Psychrotrophic bacteria in sausage
Food / Nahrung, 1993AbstractA total of 50 samples of frozen fresh beef sausage were collected from grocery stores at Beni Suef City. These samples were examined for enumeration, isolation and identification of psychrotrophic bacteria. All samples contained psychrotrophic bacteria in variable numbers.

Psychrotrophic Bacteria: Pseudomonas spp.
2022Psychrotrophic bacteria Pseudomonas spp. are currently the most commonly microbial agents isolated from spoiled milk and dairy products. They are the cause of numerous technological problems and contribute to significant economic losses in the dairy industry. Some strains of the P. fluorescens and P.

Psychrophilic and psychrotrophic microorganisms
Experientia, 1986Psychrophilic and psychrotrophic microorganisms have the ability to grow at 0 degree C. Psychrotrophic microorganisms have a maximum temperature for growth above 20 degrees C and are widespread in natural environments and in foods. Psychrophilic microorganisms have a maximum temperature for growth at 20 degrees C or below and are restricted to ...

Psychrotrophic bacteria are responsible for the highest spoilage of unprocessed or heated milk during storage because of their capacity to synthesize thermostable extracellular proteases and lipases leading to gelation, off-odours/flavours, loss of sensory quality and shelf life. This chapter critically describes and discusses various topics related to

Psychrotrophic properties of Listeria monocytogenes
Canadian Journal of Microbiology, 1972Listeria monocytogenes grew between 3 and 45C. Growth at 10C was at a rate characteristic of psychrophilic bacteria. The increase in the duration of the lag phase of growth with decreasing temperatures was expressed with a hyperbolic curve which indicated an infinite lag time at 3.3C.

Proteases from Psychrotrophs: An Overview
Critical Reviews in Microbiology, 2010Proteases are hydrolytic enzymes which catalyze the total hydrolysis of proteins in to amino acids. Although proteolytic enzymes can be obtained from animals and plants but microorganisms are the preferred source for industrial applications in view of scientific and economical advantage.

Environmental reservoirs of psychrotrophic meat spoilage fungi
New Zealand Veterinary Journal, 1977Summary The numbers of psychrotrophic fungi in various environments have been investigated as these fungi are potential meat spoilage organisms, carried into the freezing works on stock awaiting slaughter. Of a number of soils examined, those from urban and high-altitude areascontained the fewest psychrotrophic fungi.

Marine Biotechnology, 2001
A versatile system that permits genetic manipulation of a psychrotrophic deep-sea bacterium, Pseudoalteromonas sp. PS1M3, has been developed. A cryptic indigenous plasmid, pPS1M3, of 3.1 kb from the above strain was isolated and characterized. The nucleotide sequence analysis of plasmid pPS1M3 revealed the presence of one open reading frame, and its ...

Isolation and characterization of psychrotrophs from subterranean environments
Journal of Bioscience and Bioengineering, 1999Subterranean environments are potential sources for the isolation of novel microorganisms. Water and soil samples were collected at depths ranging from 10 to 1800 meters below the surface, and screening was carried out with aerobic rich and anaerobic minimal media. Two psychrotrophic and three chemoautotrophic strains were isolated.
