Answer to Question #127337 in Microbiology for Ibrahim jibrin

Question

Microorganisms were found to consume 500mg/dl of oxygen per hour 24 hours into the fermentation process, it became 350mg/dl per hour at 48 hours. What has happened?

Answer 1

Heterotrophic metabolism is the biologic oxidation of organic compounds, such as glucose, to yield ATP and simpler organic (or inorganic) compounds, which are needed by the bacterial cell for biosynthetic or assimilatory reactions.

In fermentation, another type of heterotrophic metabolism, an organic compound rather than oxygen is the terminal electron (or hydrogen) acceptor. Less energy is generated from this incomplete form of glucose oxidation, but the process supports anaerobic growth.
