INCIDENCE AND ANTIBIOTIC RESISTANCE OF PSYCHROTOLERANT BACILLUS CEREUS GROUP IN ICE CREAM SAMPLES, WITH SPECIAL REFERENCE TO BACILLUS THURINGIENSIS [PDF]

Assiut Veterinary Medical Journal, 2011
Bacillus cereus causes food-poisoning by means of enterotoxins with either emetic or diarrheal effects. Hence, psychrotolerant Bacillus cereus group occurrence in 150 ice cream samples was investigated. Mannitol-egg yolk-polymyxin B (MYP) agar medium was

Cold Stress Tolerance in Psychrotolerant Soil Bacteria and Their Conferred Chilling Resistance in Tomato (Solanum lycopersicum Mill.) under Low Temperatures. [PDF]

PLoS ONE, 2016
The present work aimed to study the culturable diversity of psychrotolerant bacteria persistent in soil under overwintering conditions, evaluate their ability to sustain plant growth and alleviate chilling stress in tomato.

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

Morphological Features and Cold-Response Gene Expression in Mesophilic Bacillus cereus Group and Psychrotolerant Bacillus cereus Group under Low Temperature

Microorganisms, 2021
At low temperatures, psychrotolerant B. cereus group strains exhibit a higher growth rate than mesophilic strains do. However, the different survival responses of the psychrotolerant strain (BCG34) and the mesophilic strain (BCGT) at low temperatures are

Microbial Diversity of Psychrotolerant Bacteria Isolated from Wild Flora of Andes Mountains and Patagonia of Chile towards the Selection of Plant Growth-Promoting Bacterial Consortia to Alleviate Cold Stress in Plants

Microorganisms, 2021
Cold stress decreases the growth and productivity of agricultural crops. Psychrotolerant plant growth-promoting bacteria (PGPB) may protect and promote plant growth at low temperatures.

Psychrotolerant plant-associated bacteria can enhance cold tolerance in crop plants

, 2023
<p>Climate change is causing warmer winter and spring periods with increased frequency of chilling and frost damage on crop plants. Psychrotolerant plant-associated bacteria could improve plant tolerance to cold stress.

Atlantinone A, a Meroterpenoid Produced by Penicillium ribeum and Several Cheese Associated Penicillium Species

Metabolites, 2012
Atlantinone A has been isolated from the psychrotolerant fungus Penicillium ribeum. The exact structure of the compound was confirmed by mass spectrometric and 1- and 2D NMR experiments. Atlantinone A was originally only produced upon chemical epigenetic

Development of a Monte Carlo simulation model to predict pasteurized fluid milk spoilage due to post-pasteurization contamination with gram-negative bacteria

Journal of Dairy Science, 2022
: Psychrotolerant gram-negative bacteria introduced as post-pasteurization contamination (PPC) are a major cause of spoilage and reduced shelf life of high-temperature, short-time pasteurized fluid milk.

Psychrobacter arenosus Bacteremia after Blood Transfusion, France

Emerging Infectious Diseases, 2013
We report a case of transfusion-associated bacteremia caused by Psychrobacter arenosus. This psychrotolerant bacterium was previously isolated in 2004 from coastal sea ice and sediments in the Sea of Japan, but not from humans. P.

Culturable bacteria associated with Antarctic lichens: affiliation and psychrotolerance [PDF]

Polar Biology, 2009
Antarctic habitats harbour yet unexplored niches for microbial communities. Among these, lichen symbioses are very long-living and stable microenvironments for bacterial colonization. In this work, we present a first assessment of the culturable fraction of bacteria associated with Antarctic lichens.
