Toxigenic Potential of Mesophilic and Psychrotolerant Bacillus cereus Isolates from Chilled Tofu

Foods, 2022
The prevalence, toxin gene profile, antibiogram, and biofilm formation to determine the virulence potential of mesophilic and psychrotolerant Bacillus cereus (B. cereus) isolated from chilled tofu were investigated.

Isolation of a Psychrotolerant and UV-C-Resistant Bacterium from Elephant Island, Antarctica with a Highly Thermoactive and Thermostable Catalase

Microorganisms, 2020
Microorganisms present in Antarctica have to deal not only with cold temperatures but also with other environmental conditions, such as high UV radiation, that trigger the generation of reactive oxygen species.

Insight Into the Diversity and Possible Role of Plasmids in the Adaptation of Psychrotolerant and Metalotolerant Arthrobacter spp. to Extreme Antarctic Environments

Frontiers in Microbiology, 2018
Arthrobacter spp. are coryneform Gram-positive aerobic bacteria, belonging to the class Actinobacteria. Representatives of this genus have mainly been isolated from soil, mud, sludge or sewage, and are usually mesophiles. In recent years, the presence of

Characterization of Mycobacterium antarcticum sp. nov., a psychrotolerant member of the genus Mycobacterium isolated from Antarctic soil [PDF]

Scientific Reports
Most species of the genus Mycobacterium are widely distributed in soil and aquatic environments; however, there is limited understanding of their distribution and adaptation to permanently cold environments.

Development of extensive growth and growth boundary models for mesophilic and psychrotolerant Bacillus cereus in dairy products (Part 1) [PDF]

Frontiers in Microbiology
Guidelines for combinations of product characteristics to prevent unacceptable growth of Bacillus cereus in foods are lacking, and models are therefore valuable for predicting these responses. B.
