Frank, Hilmer A. (Eastern Regional Research Laboratory, Philadelphia, Pa.). Influence of low incubation temperature on classification of Pseudomonas geniculata. J. Bacteriol. 84:68-71. 1962.-Biochemical and physiological properties of psychrophilic Pseudomonas geniculata isolates were determined at 8 C and at 27 C. No qualitative differences in taxonomically significant properties were observed...
Production of psychrophilic enzymes in the commonly used mesophilic expression systems is hampered by low intrinsic stability of the recombinant enzymes at the optimal host growth temperatures. Unless strategies for low-temperature expression are advanced, research on psychrophilic enzymes may end up being biased toward those that can be stably produced in commonly used mesophilic host systems....
Diatoms are a highly diversified group of algae that are widely distributed in aquatic ecosystems, and various species have different nutrient and temperature requirements for optimal growth. Here, we describe unusual psychrophilic diatoms of Cymbella in a travertine deposition environment in southwestern China in winter season.Travertine surfaces are colonized by these psychrophilic diatoms, w...
The Deepwater Horizon oil spill produced large subsurface plumes of dispersed oil and gas in the Gulf of Mexico that stimulated growth of psychrophilic, hydrocarbon degrading bacteria. We tracked succession of plume bacteria before, during and after the 83-day spill to determine the microbial response and biodegradation potential throughout the incident. Dominant bacteria shifted substantially ...
this research with the aims of microbial flora determination in pasteurized milk and it’s shelf life study based on microbial and physicochemical parameters were performed within 10 days. in this study, 60 pasteurized milk samples randomly were selected and then total count of bacteria and total psychrophilic bacteria count were performed. to investigate microbial flora of pasteurized milk, col...
Salami and Sausage are ready to eat meat products that can pose a risk for human health. This study was aimed determine the some microbiological, chemical histological properties of 31 salami 23 sausages from different companies offered sale in markets, Turkey. The total aerobic mesophilic bacteria (TAMB), yeast mould enumeration, lactic acid psychrophilic count were evaluated. water activity, ...
Abstract Hyporheic zone (HZ) is an interstitial part of groundwater. Complex physical, chemical and biological processes in HZ impact water quality. We hypothesized that groundwater upwelling improves surface with biogenic compounds lowland spring niches, it depends on among others biota communities. The research was conducted two niches suburbs Białystok. Interstitial samples were collected mi...
