Abstract:
ABSTRACTFor small-copy-number pUC-type plasmids, theinc1andinc2mutations, which deregulate replication, were previously found to increase the plasmid copy number 6- to 7-fold. Because plasmids can exert a growth burden, it was not clear if further amplification of copy number would occur due toincmutations when the starting point for plasmid copy number was orders of magnitude higher. To investigate further the effects of theincmutations and the possible limits of plasmid synthesis, the parent plasmid pNTC8485 was used as a starting point. It lacks an antibiotic resistance gene and has a copy number of ∼1,200 per chromosome. During early stationary-phase growth in LB broth at 37°C,inc2mutants of pNTC8485 exhibited a copy number of ∼7,000 per chromosome. In minimal medium at late log growth, the copy number was found to be significantly increased, to approximately 15,000. In an attempt to further increase the plasmid titer (plasmid mass/culture volume), enzymatic hydrolysis of the selection agent, sucrose, at late log growth extended growth and tripled the total plasmid amount such that an approximately 80-fold gain in total plasmid was obtained compared to the value for typical pUC-type vectors. Finally, when grown in minimal medium, no detectable impact on the exponential growth rate or the fidelity of genomic or plasmid DNA replication was found in cells with deregulated plasmid replication. The use ofincmutations and the sucrose degradation method presents a simplified way for attaining high titers of plasmid DNA for various applications.

Abstract:
In this study, the plasmid content and bacteriocin production of natural isolates of lactococci were investigated. Five bacteriocin producing lactococcal strains (Lactococcus lactis subsp. lactis BGMN1-2, BGMN1-3, BGMN1-5, BGMN1-6, and BGMN2-7) were isolated as nonstarter microflora of semi-hard homemade cheese and characterized. All isolates contained a number of plasmids. It was shown that lcnB structural genes for bacteriocin lactococcin B were located on large plasmids in all isolates. In the strains BGMN1-3 and BGMN1-5 proteinase prtP genes collocated with lcnB. Furthermore, these strains produced two additional bacteriocins (LsbA and LsbB) with genes responsible for their production and immunity located on the small rolling circle-replicating plasmid pMN5. Using deletion experiments of pMN5, minimal replicon of the plasmid and involvement of a bacteriocin locus in plasmid maintenance were identified. In addition, plasmid curing experiments showed that genes for catabolism or transport of 10 carbohydrates in the strain BGMN1-5 were plasmid located.Key words: lactococci, natural isolates, bacteriocin, plasmid curing.

Abstract:
ABSTRACTDuring the past 2 decades,Bacillus megateriumhas been systematically developed for the gram-per-liter scale production of recombinant proteins. The plasmid-based expression systems employed use a xylose-controlled promoter. Protein production analyses at the single-cell level using green fluorescent protein as a model product revealed cell culture heterogeneity characterized by a significant proportion of less productive bacteria. Due to the enormous size ofB. megaterium, such bistable behavior seen in subpopulations was readily analyzed by time lapse microscopy and flow cytometry. Cell culture heterogeneity was not caused simply by plasmid loss: instead, an asymmetric distribution of plasmids during cell division was detected during the exponential-growth phase. Multicopy plasmids are generally randomly distributed between daughter cells. However,in vivo andin vitroexperiments demonstrated that under conditions of strong protein production, plasmids are retained at one of the cell poles. Furthermore, it was found that cells with accumulated plasmids and high protein production ceased cell division. As a consequence, the overall protein production of the culture was achieved mainly by the subpopulation with a sufficient plasmid copy number. Based on our experimental data, we propose a model whereby the distribution of multicopy plasmids is controlled by polar fixation under protein production conditions. Thereby, cell lines with fluctuating plasmid abundance arise, which results in population heterogeneity. Our results provide initial insights into the mechanism of cellular heterogeneity during plasmid-based recombinant protein production in aBacillusspecies.

Abstract:
ABSTRACT A major limitation to improving small-molecule pharmaceutical production in streptomycetes is the inability of high-copy-number plasmids to tolerate large biosynthetic gene cluster inserts. A recent finding has overcome this barrier. In 2003, Hu et al. discovered a stable, high-copy-number, 81-kb plasmid that significantly elevated production of the polyketide precursor to the antibiotic erythromycin in a heterologous Streptomyces host (J. Ind. Microbiol. Biotechnol. 30:516-522, 2003). Here, we have identified mechanisms by which this SCP2*-derived plasmid achieves increased levels of metabolite production and examined how the 45-bp deletion mutation in the plasmid replication origin increased plasmid copy number. A plasmid intramycelial transfer gene, spd, and a partition gene, parAB, enhance metabolite production by increasing the stable inheritance of large plasmids containing biosynthetic genes. Additionally, high product titers required both activator (actII-ORF4) and biosynthetic genes (eryA) at high copy numbers. DNA gel shift experiments revealed that the 45-bp deletion abolished replication protein (RepI) binding to a plasmid site which, in part, supports an iteron model for plasmid replication and copy number control. Using the new information, we constructed a large high-copy-number plasmid capable of overproducing the polyketide 6-deoxyerythronolide B. However, this plasmid was unstable over multiple culture generations, suggesting that other SCP2* genes may be required for long-term, stable plasmid inheritance.

Abstract:
ABSTRACT A Thermus thermophilus selector strain for production of thermostable and thermoactive α-galactosidase was constructed. For this purpose, the native α-galactosidase gene (agaT) ofT. thermophilus TH125 was inactivated to prevent background activity. In our first attempt, insertional mutagenesis ofagaT by using a cassette carrying a kanamycin resistance gene led to bacterial inability to utilize melibiose (α-galactoside) and galactose as sole carbohydrate sources due to a polar effect of the insertional inactivation. A Gal+ phenotype was assumed to be essential for growth on melibiose. In a Gal−background, accumulation of galactose or its metabolite derivatives produced from melibiose hydrolysis could interfere with the growth of the host strain harboring recombinant α-galactosidase. Moreover, the AgaT− strain had to be Kms for establishment of the plasmids containing α-galactosidase genes and the kanamycin resistance marker. Therefore, a suitable selector strain (AgaT− Gal+ Kms) was generated by applying integration mutagenesis in combination with phenotypic selection. To produce heterologous α-galactosidase in T. thermophilus, the isogenes agaA and agaBof Bacillus stearothermophilus KVE36 were cloned into anEscherichia coli-Thermus shuttle vector. The region containing the E. coli plasmid sequence (pUC-derived vector) was deleted before transformation of T. thermophilus with the recombinant plasmids. As a result, transformation efficiency and plasmid stability were improved. However, growth on minimal agar medium containing melibiose was achieved only following random selection of the clones carrying a plasmid-based mutation that had promoted a higher copy number and greater stability of the plasmid.

Abstract:
Three plasmids of 55.0, 31.2, and 7.4 kb, designated as pXCM18-I, pXCM18-II, and pXCM18-III, respectively, were identified and isolated from strain HR13B/2 of Xanthomonas campestris pv. malvacearum. The bacterium was cured of all three plasmids in high frequency (3.1%) with heat (42 °C). The cured strains were nonmucoid and light yellow and were greatly impaired in exopolysaccharide production and virulence. Transformation of a cured strain using a mixture of purified plasmid DNA from HR13B/2 resulted in colonies carrying all six possible combinations of the three plasmids. Of the transformants, two morphologically distinct colony types were observed. The first type of transformants were mucoid and deep yellow, not distinguished from wild-type colonies in morphology, and fully complemented for exopolysaccharide production. These transformants invariably carried pXCM18-II. The second type of transformants were not distinguished from the untransformed strain in morphology but were found to be transformed after screening for plasmid content. These transformants carried either pXCM18-I, pXCM18-III, or both, but never pXCM18-II. In pathogenicity tests, each of the three plasmids restored virulence significantly, and additively, with plasmid pXCM18-I playing a predominant role.Key words: Xanthomonas campestris pv. malvacearum, cotton, plasmid, pigmentation, exopolysaccharide, virulence.

Abstract:
Salmonella Infantis carrying extended spectrum β-lactamase blaCTX-M-65 on a pESI-like megaplasmid has recently emerged in United States poultry. In order to determine the carriage rate and gene content variability of this plasmid in U.S. Salmonella Infantis, whole genome sequences of Salmonella isolates from humans and animals in the U.S. and internationally containing the pESI-like plasmid were analyzed. The U.S. Department of Agriculture Food Safety and Inspection Service (FSIS) identified 654 product sampling isolates containing pESI-like plasmids through hazard analysis and critical control point (HACCP) verification testing in 2017 and 2018. The Centers for Disease Control and Prevention identified 55 isolates with pESI-like plasmids in 2016–2018 through the National Antimicrobial Resistance Monitoring System. Approximately 49% of pESI-like plasmids from FSIS verification isolates and 71% from CDC NARMS contained blaCTX-M-65. Pan-plasmid genome analysis was also performed. All plasmids contained traN and more than 95% contained 172 other conserved genes; 61% contained blaCTX-M-65. In a hierarchical clustering analysis, some plasmids from U.S. animal sources clustered together and some plasmids from South America clustered together, possibly indicating multiple plasmid lineages. However, most plasmids contained similar genes regardless of origin. Carriage of the pESI-like plasmid in U.S. appears to be limited to Salmonella Infantis and carriage rates increased from 2017 to 2018.

Abstract:
Musty taste and odor is a serious problem for drinking water. Much data regarding its occurrence are being accumulated. However, we may be able to solve this problem by inquiring into the nature of secondary metabolism through the mevalonic acid pathway in actinomycetes and/or cyanobacteria that yield musty smelling compounds. Therefore, genetic analysis is applied to look for new solutions. By investigating Streptomyces sp. with the protocol to recover plasmid DNA, it was difficult to get the infinitesimally small covalently closed circular (ccc) plasmid. On the other hand, Streptomyces strains which have been cured, which implicates plasmids, lost phenotypic characters such as musty odor production with aerial mycelium and pigment formation. DNA in Streptomyces are unstable and often cause amplification and deletion. The existence of giant linear plasmids was detected in musty smelling strains using pulsed – field gel electrophoresis.

Abstract:
Recombinant production of pharmaceutical proteins like antigen binding fragments (Fabs) in the commonly-used production host Escherichia coli presents several challenges. The predominantly-used plasmid-based expression systems exhibit the drawback of either excessive plasmid amplification or plasmid loss over prolonged cultivations. To improve production, efforts are made to establish plasmid-free expression, ensuring more stable process conditions. Another strategy to stabilize production processes is lactose induction, leading to increased soluble product formation and cell fitness, as shown in several studies performed with plasmid-based expression systems. Within this study we wanted to investigate lactose induction for a strain with a genome-integrated gene of interest for the first time. We found unusually high specific lactose uptake rates, which we could attribute to the low levels of lac-repressor protein that is usually encoded not only on the genome but additionally on pET plasmids. We further show that these unusually high lactose uptake rates are toxic to the cells, leading to increased cell leakiness and lysis. Finally, we demonstrate that in contrast to plasmid-based T7 expression systems, IPTG induction is beneficial for genome-integrated T7 expression systems concerning cell fitness and productivity.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2012.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 96-104).<br>DNA vaccines and gene therapies that use plasmid DNA (pDNA) as a vector have gained attention in recent years for their good safety profile, ease of manufacturing, and potential to treat a host of diseases. With this interest comes increased demand for high-yield manufacturing processes. Overall, this thesis aims to develop new, innovative tools for the production of plasmid DNA biopharmaceuticals. As one part of this thesis, we designed a 1-mL fed-batch microbioreactor with online monitoring and control of dissolved oxygen, pH, and temperature, as well as continuous monitoring of cell density. We used the microbioreactors to scale down temperature-induced production of a pUC-based DNA vaccine vector, pVAX1-GFP. Scaled-down processes can facilitate high-thoughtput, low-cost bioprocess development. We found that the microbioreactors accurately reproduced the behavior of a bench-scale bioreactor as long as key process parameters, such as dissolved oxygen, were held constant across scales. The monitoring capabilities of the microbioreactors also provided enhanced process insight and helped identify conditions that favored plasmid amplification. A second aspect of this thesis involved construction and characterization of a new DNA vaccine vector based on a runaway replication mutant of the R1 replicon. Runaway replication plasmids typically show increased amplification after a temperature upshift. However, we found that our new vector, pDMB02-GFP, gave higher yields during constant temperature culture at 30"C, reaching a maximum of 19 mg pDNA/g DCW in shake flasks. We gained mechanistic insight into this behavior by measuring RNA and protein expression levels of RepA, a plasmid-encoded protein required for initiation of replication at the R1 origin. Through these studies we found that RepA levels may limit plasmid amplification at 42*C, and relieved this limitation by increasing RepA translation efficiency via a start codon mutation. We also scaled up production of pDMB02-GFP at 300C from 50-mL shake flasks to 2-L bioreactors. Initial scale up efforts resulted in increased growth rate compared to the shake flasks, accompanied by very low plasmid yields. Decreasing the growth rate by limiting dissolved oxygen increased plasmid specific yield and emerged as a viable strategy for maintaining productivity during scale up.<br>by Diana M. Bower.<br>Ph.D.

Abstract:
Hepatitis-C Virus (HCV) remains the leading cause of liver transplant in the US and the UK, and the World Health Organization (WHO) estimates that 71 million people are infected worldwide. A vaccine would drastically impact the healthcare-associated burdens that HCV causes globally. The objective of this master’s thesis project is to produce human antibody (IgG) against HCV. This project will focus on the monoclonal antibodies (mAbs) HEPC3, AR3C, HEPC74, and HCV1. These four antibodies have been isolated from patients who have successfully cleared the infection, and their sequences and structures are available in the public domain. These four antibodies have also shown to bind to E2, a glycoprotein on the surface HCV that is crucial for viral binding and entry. This interaction of the mABs with E2 has been implicated in viral neutralization, making them promising choices for this study. Overall, 3 out of 4 mAbs were successfully cloned and produced. The unsuccessful antibody, HEPC74, was discovered to have failed due to an error in the plasmid sequence. Just as the western blot to confirm secretion was ready to be run, the laboratory closed due the Covid-19 outbreak. Therefore, the data can officially declare a ¾ mAb production success, however it is safe to assume that the alternative clone for HEPC74 was also a success due to a perfect sequence match. Since the primary objective of this project was to successfully clone and produce these four antibodies, then this study is considered an overall success. Lastly, this study examined how the same protocol  could be applied the SARS-CoV-2 outbreak, by the cloning and production of anti-RBD IgG and testing them for viral neutralization.<br>Hepatit-C (HCV) är fortsatt den enskilt största orsaken till levertransplantationer med uppskattningsvis 71 miljoner infekterade globalt sett, enligt världshälsoorganisationen (WHO).Ett vaccin mot HCV skulle drastiskt minska trycket på global hälso- och sjukvård. Syftet med detta projekt är att producera antikroppar (igG) mot HCV. Projektet fokuserar på HEPC3, AR3C, HEPC74 och HCV1 som är monoklonala antikroppar (mAbs). Dessa antikroppsvarianter har isolerats från patienter som tillfrisknat från infektion. Både DNA-sekvenser och strukturer av antikropparna finns offentligt tillgängliga. Dessa fyra antikroppar har också visats kunna binda till E2 som är ett membranbundet glykoprotein hos HCV som är centralt för viral adhesion och fusion. Interaktionen mellan dessa mAbs och E2 har visat sig neutralisera virulens, vilket gör dem till lovande kandidater för denna studie. Tre av fyra mAbs kunde klonas och produceras framgångsrikt. Försöket med HEPC74 misslyckades på grund av ett fel i plasmidsekvensen och just som western blot skulle genomföras för att bekräfta sekretion av en alternativ klon avslutades the praktiska arbetet med anledning av Covid-19 utbrottet. Resultaten visar entydigt att tre av fyra mAb producerades framgångsrikt. Det går dock att anta att det andra försöket med HEPC74 sannolikt också lyckades pga perfekt sekventiell matchning. Då det huvudsakliga syftet med projektet var att framgångsrikt klona och producera dessa fyra antikroppar så kan studien anses vara framgångsrik. Slutligen så undersöktes huruvida samma förfarande kunde appliceras mot SARS-CoV-2 genom kloning och produktion av anti-RBD IgG och tester av viral neutralisering.

Different hydrophobic amino acid sequences, beingeither theoretically designed or representing transmembraneregions of bacterial or viral origin, were fused on gene leveleither N-terminally or C-terminally to allow association withiscoms. In addition, affinity tags derived from<i>Staphylococcus aureus</i>protein A (SpA) or streptococcalprotein G (SpG), were incorporated to allow efficient recoveryby means of affinity chromatography. A malaria peptide, M5,derived from the central repeat region of the<i>Plasmodium falciparum</i>blood-stage antigen Pf155/RESA,served as model immunogen in these studies. Furthermore,strategies for<i>in vivo</i>or<i>in vitro</i>lipidation of recombinant immunogens for iscomincorporation were also investigated, with a model immunogendeltaSAG1 derived from<i>Toxoplasma gondii</i>. Both strategies were found to befunctional in that the produced and affinity purified fusionproteins indeed associated with iscoms.

Abstract:
The purpose of gene therapy is to introduce foreign genetic material into host cells to either supplement aberrant genes or to endow additional biological functions. To date, however, there has been only modest progress towards this goal, mainly due to the lack of safe, effective and broadly applicable delivery methods. Functional nanodiamonds (NDs) are rapidly emerging as promising platform carriers for next-generation therapeutics due to their innate biocompatibility, scalability, precise particle distribution, high surface area-to-volume ratio, near-spherical aspect ratio, and easily adaptable carbon surface for bioagent attachment. NDs have been functionalized with a range of therapeutics, proteins, antibodies, DNA, polymers, and other assorted biological agents. Furthermore, NDs are stable and dispersible in water, making them a promising and clinically important modality in improving the efficacy of the treatment of diseases and even some cancers at the molecular level. Mitochondrial function (MTT) and luminescent ATP production assays have demonstrated that NDs are not toxic to a wide variety of cell types. In this study, we functionalized NDs with amine groups via either covalent attachment of (3-aminopropyl) trimethoxysilane or surface immobilization of 800 Da low molecular weight polyethyleneimine (LMW PEI800) for plasmid DNA delivery. The latter delivery approach combines complementary characteristics of PEI800 and NDs to create a hybrid material that exhibits the high transfection efficiency of high molecular weight PEI, but without the inherent high cytotoxicity.
