Thermobionts are organisms that tolerate low temperatures. The normal pH range for microorganisms is from 4 to 8. Bacillus alcalophilus prefers pH above 7 for growth. Uptake of phosphate by microorganisms as a function of phosphate concentration conforms to Michaelis-Menten kinetics. There will be 15 questions of this type on the Term Test.
Anoxygenic photosynthesis is performed by nitrogen-fixing cyanobacteria.
Prokaryotes cannot withstand high temperatures as well as eukaryotes. Allelopathy is a term used to describe parasitism of fungi by viruses. Bacteriophages are viruses which use bacteria hosts. Neutralism is favoured by low metabolic rates and high population density. 2 SO 4 thus preventing acidophobic sulfur oxidizing bacteria from invading.
