Chemoheterotrophs

Chemoheterotrophs Organic compounds Oxidation-reduction reactions Organic compounds, e.g., glucose All animals, most microorganisms, nonphotosynthetic plant tissue such as roots, photosynthetic cells in the dark... 

Where a single substrate serves both as carbon and energy source, which is the case for chemoheterotrophic organisms used for biomass production, we can write ...

In a system defined by wastewater in a sewer network, the heterotrophic bacteria dominate the microbial community, i.e., organic compounds are required as a carbon source. Furthermore, the energy source (electron donor) for the heterotrophs is primarily also organic compounds, i.e., the heterotrophs that dominate wastewater in sewers are chemoheterotrophic (chemoorganotrophic) microorganisms. 

Heterotrophic mode heterotrophs obtain energy and carbon from organic substances. Thus, chemoheterotrophs obtain energy from oxidations, whereas photoheterotrophs obtain energy from photosynthesis with an organic electron donor requirement. 

Streptomyces Streptomyces microorganisms are actually actinomycetes. They are Gram-positive, chemoheterotrophic microorganisms that can comprise 5 - 20 % of the bacterial count in solid phases. These microorganisms produce antibiotics, including streptomycin.

Organisms that use CO2 as the principal carbon source are defined as autotrophic organisms that use organic compounds as the principal carbon source are defined as heterotrophic. A combination ofthese two criteria leads to the establishment of four principal categories (i) photoautotrophic, (ii) photoheterotrophic, (Hi) chemoautotrophic and (iv) chemoheterotrophic organisms.

Many chemoheterotrophic bacteria oxidize organic compounds with molecular oxygen (Fig. 1.2). They oxidize many organic compounds such as carcasses and excreta of animals, and dead plants, and participate in the cleaning pollution from the surface of Earth.
