Sulphur Cycle & Microbial Role in It

The sulfur cycle is the collection of processes by which sulfur moves between rocks, waterways and living systems. Such biogeochemical cycles are important in geology because they affect many minerals. Biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in …

Nitrogen Cycle: Converting Nitrogen into Multiple Chemical Forms

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and …

Interactions among Microbial Populations

Organisms living together in a community influence each other directly or indirectly under natural condition. All vital process of living such as growth, nutrition, reproduction required interactions between individuals of same species, or between species which are inter- and intra-related. Such relationships of individuals in a population of an ecosystem …
