Question

a microbiologist describes an organism as a saprobic, thermoduric, barophilic, coccus. describe the organisms metabolic, structural and growth conditions in layperson nonscience terms

Answer 1

The microbiologist describes an organism as saprobic, thermoduric, barophilic,coccus. These microorganisms are termed in one word as Psychrophilic microorganisms. They have the ability to grow at 0 degree celsius.They have a maximum temperature for growth at 20 degree celsius and or below and are restricted to permannetly cold habitats.This ability to grow at a low temperature may be correlated with a lower temperature characteristic, an increasing proportion of unsaturated fatty acids in the lipid phase of the cell membrane, which makes it more fluid, and a protein conformation functional at lower temperature. The relatively low maximum temperature of growth for these microorganisms is often considered to be due to the thermolability of one or more essential cellular components, particularly enzymes, while some degradative activities are enhanced, resulting in an exhaustion of cell energy, a leakage of intracellular substances or complete lysis. Psychotrophic microorganisms are well-known for their degradative activities in foods.Some are pathogenic or toxinogenic for man, animals or plants. However in natural microbial ecosystems psychotrophic microorganisms can play a large role in the biodegradation of organic matter during cold seasons.
