The fate of aerobic heterotrophic bacteria single-cell protein production under differnet C/N ratios

The fate of aerobic heterotrophic bacteria single-cell protein production under differnet C/N ratios

Aerobic heterotrophic bacteria represent an upcoming source of alternative protein for animal feed. Carbon-to-nitrogen (C/N) ratio are known to affect the composition microbial community, in turn the performance of the bioreactor. This study investigated two C/N ratios, 100:1 and 100:3.5 and their i...
