Why Microbiology Microbial Metabolism

Free-living, non-photosynthetic bacteria depend on soil organic matter as a food source whereas the photosyntheticmicroorganisms may derive their food from the products of photosynthesis.

The nitrogen fixing activity of free-living, non-photosynthetic, aerobic bacteria is strongly dependent on favorablemoisture conditions, oxygen, and an organic food source. Anaerobic representatives (Clostridium) predominate in grassland andwaterlogged soils and soil aggregates where moisture conditions and organic substrates are available but oxygen supply to themicro-environment of the bacteria is severely restricted.

Microbial metabolism - Wikipedia

Not only are microorganisms extremely widespread, but within the microbial world there is also an impressive number of different metabolic pathways. You know this because of the compounds that they consume and produce, as well as from the study of microbial genes found in nature.

carbon) it needs to live and reproduce

To betterunderstandthe biology of microbial interactions, Stanford'smicrobiologists, leadersin the fields of microbial symbiosis andpathogenesis, cell cycle controland development, and gene regulation andmetabolism, have organized theirresearch and teaching efforts into a newmulti-disciplinary program.

Microbial metabolism - an overview | ScienceDirect Topics

Sergei N. Winogradsky was one of the first microbiologists to study the organisms found in complex biofilm communities. One of the strategies he used to isolate organisms from nature was a miniature model of a pond cross-section that is now called a Winogradsky column. It is a simple device for constructing a stratified ecosystem and provides a visual example of various modes of metabolism and zonation in the microbial world. It is a classic demonstration of the metabolic diversity of prokaryotes. The poster shows the different bacteria found in each zone, their metabolic niches, and the gradients of energy sources.

Although this is not a problem for anaerobic bacteria, it could be a major problem for the aerobic species such as cyanobacteria (which generate oxygen during photosynthesis) and the free-living aerobic bacteria of soils, such as Azotobacter and Beijerinckia.

Diversity of Microbial Metabolism

Anoxygenic photosynthesis does not make oxygen and is used by the purple and green bacteria (types of bacteria that live in anaerobic aquatic environments).

Nitrogen fixation - University of Edinburgh

Oxygenic photosynthesis generates oxygen and is used by the cyanobacteria (a type of bacteria) and algae (a eukaryote), as well as all living plants.
