Abstract:

Brackish water shrimp aquaculture activities often result in organic waste from excess of unconsumed foodstuff and biological waste from shrimp biological waste. The high organic contents increase the levels of ammonia, which is toxic to shrimp and many other aqua lives. One of the most widely used organic material biodegradation system as biofilters, biofilm has not yet seen many uses in shrimp aquafarm waste management. This study aims to isolate and screen biofilm-forming primary bacteria with abilities to degrade ammoniacal nitrogen compounds. The processes involved in this study are locat

Abstract:

Pseudomonas aeruginosa (P. aeruginosa) is ubiquitous in nature, and may be a causative agent in severe, life-threatening infections. In >60% of cases, β-lactam antibiotics are used in the therapy of P. aeruginosa infections, therefore the emergence of carbapenem-resistant P. aeruginosa (CRPA) is a signiﬁcant clinical concern. In this study, phenotypic methods were used to characterize ﬁfty-four (n = 54) P. aeruginosa isolates, which were included based on their suspected non-susceptibility to meropenem. Minimum inhibitory concentrations (MICs) of meropenem, ceftazidime, cefepime, ciprofloxa

Abstract:

Acinetobacter baumannii (A. baumannii) is an important nosocomial pathogen, which may be a causative agent in a wide-range of human pathologies. Carbapenems are usually considered the last safe and eﬀective choice of drugs for the treatment of Gram-negative infections. The emergence of carbapenem-resistant A. baumannii (CRAB) is a critical public health issue as they leave clinicians with limited therapeutic options. In this study, phenotypic methods were used to characterize sixty-two (n = 62) A. baumannii isolates, which were included based on their suspected non-susceptibility to meropenem.

Abstract:

Biofilm resistance to antimicrobials is a complex phenomenon, driven not only by genetic mutation induced resistance, but also by means of increased microbial cell density that supports horizontal gene transfer across cells. The prevention of biofilm formation and the treatment of existing biofilms is currently a difficult challenge; therefore, the discovery of new multi-targeted or combinatorial therapies is growing. The development of anti-bioﬁlm agents is considered of major interest and represents a key strategy as non-biocidal molecules are highly valuable to avoid the rapid appearance of

Quorum sensing (QS) is a form of microbial communication that relies on small signal molecules to regulate group behaviors such as bioﬁlm formation in response to population density. In this study, we attempted to apply the paradigm of bacterial QS to aerobic granular sludge (AGS) formation for wastewater treatment. An essential element of interspecies QS signals, boron, was added to a sequencing batch reactor (SBR) to stimulate AGS growth. Bioassays elaborated the activity of autoinducer-2 (AI-2). We found that boron accelerated AGS growth, resulting in improved settlement performance and inc

Abstract:

An anaerobic upflow blanket filter (UBF) was employed for the treatment of dye wastewater containing cationic red X-GRL (X-GRL) in this study. The bacterial community in the UBF at its stable state was investigated by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). The results showed that all color and the majority of chemical oxygen demand (COD) (92–74%) can be removed as the dye load increased from 33 to 134 g/(m3 d). The removal of color and COD were mostly attributed to the anaerobic activated sludge in the reactor. According to the DGGE fingerprints, the bact

Abstract:

Extracellular DNA (eDNA) is an abundant matrix component that protects biofilm from environmental stress, facilitate horizontal gene transfer, and serve as a source of nutrients. eDNA is also found in Listeria monocytogenes biofilm, but it is unknown to which extent its importance as a matrix component varies in terms of phylogenetic relatedness. This study aims to determine if these variations exist. Biofilm forming capacity of ten L. monocytogenes strains of different phylogenetic lineages and serotypes was examined using crystal violet assay at 37°C and 22°C. eDNA content was evaluated fluo

Abstract:

The biological denitrification method applied to treat municipal sewage containing low levels of nitrogen compounds and contaminated groundwater is very popular. There are few studies in the literature on the treatment of industrial wastewater containing high levels of nitrogen compounds. To assess the feasibility of biofilm and immobilized cells for treating wastewater which contains high-strength nitrogen compounds, the biofilm characteristics of the biological denitrification process in attached-growth reactors were studied. The Richardson-Zaki relationship can adequately describe the biopa

Abstract:

The influences of reactor conditions (substrate loading rate and shear) and microbial characteristics (yield and growth rate) on the structure of biofilms is discussed. Based on research on the formation of biofilms in Biofilm Airlift Suspension (BAS) reactors a hypothesis is postulated that the ratio between biofilm surface loading and shear rate determines the biofilm structure. When shear forces are relatively high only a patchy biofilm will develop, whereas at low shear rates the biofilm becomes highly heterogeneous with many pores and protuberances. In case of a right balance smooth and s

Abstract:

Photographic chemistry has long been a complex combination of inorganic metal-halide and organic chemistries and polymer science. We at the P.R.I, have managed to add biology to this stew.Silver has long been known as a toxicelement to microbes, and so used as a drug to kill bacteria. But there are bacteria that can survive in environments high in silver. It has been reported that some bacteria can accumulate up to 25% of their dry biomass as silver, and so acquire resistance to the toxic effects of silver. Also, a recent article in the Proc. Nat. Acad.Sci. describes the intracellular depositi
