Abstract:
Medium-chain-length polyhydroxyalkanoates (mcl-PHAs) have gained great attention as a new green alternative to petrochemical-derived polymers. Due to their outstanding material properties they can be used in a wide range of applications. Pseudomonas putida KT2440 is a metabolically versatile producer of mcl-polyhydroxyalkanoates. Although the metabolism of polyhydroxyalkanoate synthesis by this bacterium has been extensively studied, the comparative proteome analysis from three growth stages of Pseudomonas putida KT2440 cultured with oleic acid during mcl-PHA synthesis has not yet been reported. Therefore; the aim of the study was to compare the proteome of Pseudomonas putida KT2440 at different time points of its cultivation using the 2D difference gel electrophoresis (2D-DIGE) technique. The analyses showed that low levels of a nitrogen source were beneficial for mcl-PHA synthesis. Proteomic analysis revealed that the proteins associated with carbon metabolism were affected by nitrogen starvation and mcl-PHA synthesis. Furthermore, the induction of proteins involved in nitrogen metabolism, ribosome synthesis, and transport was observed, which may be the cellular response to stress related to nitrogen deficiency and mcl-PHA content in bacterial cells. To sum up; this study enabled the investigators to acquire a better knowledge of the molecular mechanisms underlying the induction of polyhydroxyalkanoate synthesis and accumulation in Pseudomonas putida KT2440 that could lead to improved strategies for PHAs in industrial production.

Abstract:
The rapidly growing interest on polyhydroxyalkanoates (PHA) processing for biomedical purposes is justified by the unique combinations of characteristics of this class of polymers in terms of biocompatibility, biodegradability, processing properties, and mechanical behavior, as well as by their great potential for sustainable production. This article aims at overviewing the most exploited processing approaches employed in the biomedical area to fabricate devices and other medical products based on PHA for experimental and commercial applications. For this purpose, physical and processing properties of PHA are discussed in relationship to the requirements of conventionally-employed processing techniques (e.g., solvent casting and melt-spinning), as well as more advanced fabrication approaches (i.e., electrospinning and additive manufacturing). Key scientific investigations published in literature regarding different aspects involved in the processing of PHA homo- and copolymers, such as poly(3-hydroxybutyrate), poly(3-hydroxybutyrate-co-3-hydroxyvalerate), and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), are critically reviewed.

Abstract:
To develop a system for gene replacement in Nocardia corallina, a protocol for electroporation was optimized by systematic alterations of growth conditions, field strength, time constant and the electroporation buffer. Transformation efficiencies of 0.5 × 106–3 × 106transformants/μg plasmid DNA were obtained routinely. The gene encoding the polyhydroxyalkanoate (PHA) synthase I of N. corallina was cloned and interrupted by insertion of a kanamycin-resistance gene. The resulting plasmid was introduced into N. corallina by electroporation to inactivate the wild-type gene by homologous recombination. Kanamycin-resistant clones were screened by Southern hybridization for the absence of the wild-type gene and analyzed for PHA accumulation.Key words: gene replacement, Nocardia, polyhydroxyalkanoates (PHAs).

Abstract:
Exploration for promising polyhydroxyalkanoates (PHA) producers is a continuous process as effort to mitigate the accumulation of synthetic plastic is on the rise. The present study focuses on isolation of indigenous polyhydroxyalkanoates producing bacteria from soil, waste water effluent and organic waste sample of Obio-Akpor, LGA. Screening of the selected bacteria isolates for polyhydroxyalkanoates production was based on viable plate method followed by microscopic visualization using Sudan black B. The PHA producing abilities of the selected isolates were estimated by gravimetric method and the positive isolates were detected for the presence of PHA synthase gene and identified up to genus level. Results revealed that out of 106 isolates, 55 were suspected to accumulate PHA after screening and produced PHA in the range of 0.2-1.1 g/L. Six potential isolates produced highest PHA yield and their phaC genes were successfully amplified from genomic DNA. Based on morphological, cultural and biochemical characteristics, the six isolates were tentatively identified to the genus Bacillus sp, Lysinibacillus sp and Pseudomonas sp. The result of the present study indicated that these bacterial isolates have the potential of producing PHA and their potential harnessed for future purposes.

Abstract:
In this research, the utilisation of used transformer oil (UTO) as carbon feedstock for the production of polyhydroxyalkanoate (PHA) was targeted; with a view to reducing the environmental challenges associated with the disposal of the used oil and provision of an alternative to non-biodegradable synthetic plastic. Acinetobacter sp. strain AAAID-1.5 is a PHA-producing bacterium recently isolated from a soil sample collected in Penang, Malaysia. The PHA-producing capability of this bacterium was assessed through laboratory experiments in a shake flask biosynthesis under controlled culture conditions. The effect of some biosynthesis factors on growth and polyhydroxyalkanoate (PHA) accumulation was also investigated, the structural composition of the PHA produced by the organism was established, and the characteristics of the polymer were determined using standard analytical methods. The results indicated that the bacteria could effectively utilise UTO and produce PHA up to 34% of its cell dry weight. Analysis of the effect of some biosynthesis factors revealed that the concentration of carbon substrate, incubation time, the concentration of yeast extract and utilisation of additional carbon substrates could influence the growth and polymer accumulation in the test organism. Manipulation of culture conditions resulted in an enhanced accumulation of the PHA. The data obtained from GC-MS and NMR analyses indicated that the PHA produced might have been composed of 3-hydroxyoctadecanoate and 3-hydroxyhexadecanoate as the major monomers. The physicochemical analysis of a sample of the polymer revealed an amorphous elastomer with average molecular weight and polydispersity index (PDI) of 110 kDa and 2.01, respectively. The melting and thermal degradation temperatures were 88 °C and 268 °C, respectively. The findings of this work indicated that used transformer oil could be used as an alternative carbon substrate for PHA biosynthesis. Also, Acinetobacter sp. strain AAAID-1.5 could serve as an effective agent in the bioconversion of waste oils, especially UTO, to produce biodegradable plastics. These may undoubtedly provide a foundation for further exploration of UTO as an alternative carbon substrate in the biosynthesis of specific polyhydroxyalkanoates.

Abstract:
Polyhydroxyalkanoates (PHA) are biodegradable polyesters, which are produced by various bacteria including numerous halophiles. Employment of halophilic strain for PHA production brings numerous benefits such as robustness of the process against contamination by ubiquitous mesophiles or possibility to isolate polymer from bacterial biomass via hypotonic lysis. In this work, we screened three moderate halophiles – Halomonas halophila, Halomonas organivorans and Halomonas salina for the presence of phaC gene encoding for PHA synthase and, subsequently, we have investigated their PHA production potential on various sugars. Among tested strains, H. organivorans demonstrated the extraordinary capacity of PHA production in particular on galactose and mannose since on these saccharides PHA content in dried bacterial cells reached 83 and 90 wt. % on mannose and galactose, respectively. Therefore, H. organivoras can be considered being promising PHA producing strain in particular suitable for the valorization of lignocellulose materials rich in galactomannans such as spent coffee grounds.

Abstract:
Presented work was focused on biodegradability of bacterial natural and modified polyesters and their composites. The first part of the work was focused on study of influence of PHA granules structure on their biodegradability using selected enzymes and influence of physiological conditions on PHA stability. Overall, tested polymer either in crytalinne or amorphous phase seems to be rezistent to attack of seleced hydrolytic enzymes such as lipases or proteases and is stable in simulated physiological fluids as well. Because of thies results, it is possible to use tested PHA materials in biomedical applications requiring rather resistant biomaterials. Second part of the work was focused on microbial degradation of modified PHA materials considering their potential environmental impact. Both mixed thermophillic culture originaly used in wastewater treatment plant and bacterial strain Delftia acidovorans were employed for biodegradation tests. Composites containing chlorine PHB and PHB films modified using plasticizers were tested. Films containing chlorine PHB cause inhibition of biomass growth to both tested cultures. The highest rate of degradation (31%) was observed in presence of bacterial culture with film containing 10% chlorine PHB. The results show that used microbial population is important factor affecting biodegradability.

Abstract:
Polyhydroxyalkanoates (PHA) are microbial storage polyesters that represent a renewable and environmentally friendly alternative to petrochemical plastics. However, their production and use are severely disadvantaged by the high production cost. The use of extremophilic PHA producers is one of the ways to reduce the cost of PHA production. Extremophiles bring numerous advantages resulting from the high robustness of the process against microbial contamination. In this doctoral thesis, attention was focused on the study of PHA production using selected halophilic and thermophilic microorganisms. Representatives of the genus Halomonas were mainly from public collections of microorganisms. Two promising PHA producers on waste frying oil were identified, namely Halomonas hydrothermalis and Halomonas neptunia. Both strains achieved good PHA yields in flask experiments. With the addition of suitable structural precursors, they were also able to produce copolymers with interesting material properties. However, in the proposed thesis, the main emphasis was placed on the study of PHA production using thermophilic microorganisms. As a part of the work, the isolation of thermophilic PHA producers from various thermophilic consortia (active sludge, compost, etc.) was performed. During isolations experiments, an original isolation procedure was designed using changes in osmotic pressure, the so-called osmoselection. Dozens of promising thermophilic PHA producers were obtained thanks to this original approach. They were taxonomically classified using 16S rRNA and tested for production potential. The most promising PHA producer was the isolate which was classified as Aneurinibacillus sp. H1. This bacterium is able to utilize a variety of substrates, including waste glycerol, to produce PHA. Even more important is the capability of synthesizing copolymers with a high content of 4-hydroxybutyrate. The monomer composition of the PHA copolymer and thus the material properties of the prepared copolymer can be controlled by suitable adjustment of the cultivation conditions. The prepared copolymer P(3HB-co-4HB) has unique properties and the great application potential in numerous high-end applications, for example in the field of health care, food industry or cosmetics.

Abstract:
This diploma thesis deals with testing, optimazing and comparing methods for the identification of bacteria producing polyhydroxyalkanoates. Work included cultivation and microscopy methods, wherein the bacterial cells were stained with lipophilic dyes Nile red and Sudan black. Further, we also used flow cytometry and spectroscopic methods - Raman spectroscopy and infrared spectroscopy with Fourier transformation, and molecular biological methods, which analyzed the presence of a gene encoding PHA synthase (phaC) by polymerase chain reaction (PCR). PCR assay consist of two reactions, the firt on eis based on amplification of phaC gene along with 16S rRNDA gene, which is common for all the bacteria (multiplex PCR). The second reaction is focused on specific amplification of PHA synthase catalyzing biosynthesis of mcl-PHA. In order to overcome false positive results typical for methods analyzing genotype and also to avoid false negative results occuring in fenotype analyzing methods, the best strategy is to combine both aproaches. According to our results, analysis of presence of phaC gene by PCR can be combined with methods capable of determining presence of PHA in bacterial cells. For this purpose, Raman microspectroscopy seems to be very promising tool, since it is able to detect low content of PHA in cells and PHA can not be confused with other lipid metabolites. The results provide an overview of test methods, their advantages and disadvantages and also to compare different criteria according to which it is possible to choose the method of identification in depending on the adjustable requirements.

Abstract:
The aim of this diploma thesis was study of the isolation of polyhydroxyalkanoates using a commercial surfactant and selected biosurfactants, which were sophorolipids, coconut soap, lecithin, lauryl glucoside, coco glucoside and cocamidopropyl betaine. PHA was isolated from Schlegelella thermodepolymerans DSM 15344, where the amount of NaCl in the production medium was first optimized. The molecular weight of the isolated polymer was analyzed by SEC-MALS. The largest structural changes were recorded for coconut soap. Possible impurities in the isolated polymer were analyzed by infrared spectrometry (ATR-FTIR). The least protein contamination of the polymer was recorded with coconut soap. From the above biosurfactants, coconut soap, lauryl glucoside and coco glucoside were selected, because the highest purity of PHA was obtained. However, coconut soap had the greatest potential. The isolation temperature and surfactant concentration were optimized for selected biosurfactants. The best results were obtained at 90 °C and a concentration of 5 g/L. Furthermore, the versatility of the isolation method was tested using selected biosurfactants on various thermophilic microorganisms, which were Chelatococcus composti DSM 101465, Schlegelella thermodepolymerans DSM 15264, Tepidimonas taiwanensis LMG 22826 and Aneurinibacillus thermoaerophilus H1.

Abstract:
This diploma thesis focuses on the molecular characterization of selected PHA producers. Within this work, the PHA producing thermophilic isolates originating from the samples of activated sludge and compost were identified and characterized using molecular biological methods. By sequencing the 16S rRNA gene, the thermophilic isolates were identified and taxonomically classified into the Firmicutes bacterial phylum. In these bacterial isolates, the ability to produce PHA at the genotype level was determined by conventional PCR detection of the phaC gene encoding PHA synthase, which is a key enzyme in PHA biosynthesis. Class I, II and IV PHA synthases were detected in most of the isolated bacteria, wherein class I and II PHA synthases are not characteristic for these bacterial genera. The largest proportion of isolates was identified for the species of thermophilic bacterium Aneurinibacillus thermoaerophilus, in which class IV PHA synthase was detected. In the second part of the diploma thesis, the RT-qPCR method was implemented to study the expression of selected genes of the bacterium Cupriavidus necator H16 involved in PHA metabolism. As part of the implementation of this method, PCR-based detection of selected genes was optimized and quantification of genes using real-time PCR was performed. The tested method included steps of RNA isolation, cDNA synthesis and quantification of gene segments for which the critical points of the method were determined based on the obtained data.

Objectives of the thesis. Management and monitoring of a pilot scale process for the microbial synthesis of intracellular biopolymer (polyhydroxyalkanoates, PHA) by using the fermentation liquids of municipal sewage sludge as carbon source. Working methodology. The work is based on pilot-scale aerobic process, investigating the possibility to use a real feedstock, the fermented stream rich in volatile fatty acids (VFA) obtained by the anaerobic fermentation process of sewage sludge. The process needs to be judged in terms of stability and technical feasibility, as well as maximum PHA accumulation capacity of the mixed microbial culture PHA-producer. Experimental part planned. Long-term pilot scale aerobic process (3-4 month) for the cultivation of a mixed microbial consortia highly enriched in PHA-accumulating microorganisms; the cultivated biomass will be evaluated in terms of storage response parameters (PHA storage yield; PHA storage rate). The process needs to be also evaluated in terms of robustness and stability, for its application at larger scale. Medium-low organic loading rate (OLR) and short hydraulic retention time (HRT) will be applied to sustain a good selection on PHA-storing biomass. This biomass will be tested in its accumulation capacity in order to quantify the maximum PHA content in the biomass. A final mass balance will be also assessed as first step for future technical-economic analysis of the technology. Research area. Chemical plants (09 / D3) - Industrial biochemical processes Expected results. The selection of PHA-storing biomass will be evaluated in terms of: a) storage rate (expected values 200-300 mgPHA/(gX h)), b) storage yield (expected value 0.4-0.6 gPHA/gVFA). The accumulation potential of the biomass could be around 40-50% of PHA as percentage in terms of cell dry weight (w/w). The last part of the thesis will be dedicated to the calculation of the overall yield, as gPHA per g of Carbon Source. This value is pivotal for the technical-economical evaluation of the technology.

Abstract:
The aim of this work is study of utilization of PHA producing bacteria in bioremediation technologies. For this study were used bacteria Pseudomonas putida KT2440 and two isolates from soil contaminated by petroleum - Pseudomonas gessardii (D2) a Pseudomonas fulva (D3). The experimental part describes especially study of feather biodegradation using selected microbial strains. All the tested bacterial strains were capable of feather degradation and utilization as the sole carbon source. During biodegradation experiment, we monitored weight loss of feather, protease and keratinase activity, concentration of bacterial biomass and PHA content as well as pH. The highest biodegradation ability and keratinase activity was observed in Pseudomonas putida. None of tested bacteria accumulated detectable amount of PHA during growth on waste feather, nevertheless, bacterial biomass grown during feather degradation can be used as an inoculum for PHA production on waste frying oil and octanoic acid. Using this experimental setup, high PHA content (54% of cell dry weight) was achiaved in Pseudomonas putida. Another part of the thesis deals with biodegradation of petroleum oil. The highest capability of growth on this carbon source were determined in Pseudomonas fulva.

Abstract:
Interest in noise control has been growing in recent years and efforts are under way to improve the acoustic performance of existing sound absorbers and also to replace the non-recyclable ones with environmentally friendly materials. Present study describes the research on fabrication, improvement of acoustic absorption and enhancement of mechanical strength of bio-based open-cell foams. Through this study, highly porous open-cell Polylactide (PLA) foams were fabricated by a new fabrication method combining particulate leaching technique and compression molding. Foamed structures were fabricated with PLA and Polyethylene glycol (PEG) with salt as the particulate. Pore size of the foam was controlled by salt particulates and higher interconnectivity was achieved by the co-continuous blending morphology of PLA matrix with water-soluble PEG. As a result of novel secondary porous structure, acoustic performance of PLA foams was successfully improved. One issue with application of bio-based open-cell foams is the weak structure. To improve mechanical characteristics of PLA foams, different polymer composites of PLA and Polyhydroxyalkanoate (PHA) were foamed and characterized in terms of acoustic performance, mechanical properties and foam morphology. Polymers used in this study are bio-based which is of great importance considering huge amount of foams used as acoustic absorbers in various industries.
