Biodegradable materials are those materials which can easily be decomposed by the action of microorganisms. Microorganisms degrade the materials and are beneficial for the environment. Biodegradable plastics have the ability to replace petroleum-based plastics which are non-biodegradable. Some bacteria produce polyhydroxyalkanoate (PHA). It is a polymer having carbon-based storage molecule which is similar to plastics based on petroleum. Microbial metabolites are produced after a metabolism reaction by microorganisms. Primary metabolites are produced during active metabolism as a by-product while secondary metabolites are produced after the culture has moved to stationary phase .

Answer 1

Question

Definition Definition Phase during which the number of bacteria cell deaths gradually equals the number of viable or actively dividing cells due to decreased reproduction rate. Microbes utilize all nutrients present in the growth medium to multiply during the growth of the bacterial population, which results in the deposition of waste matter, toxins, and inhibitory compounds in the media. This changes media conditions, such as temperature and pH, creating an unfavorable environment for bacterial growth. Here, the growth rate becomes stabilized.
