Biological product: Baker's yeast Describe each method and equipment utilized in the upstream process of this biological product.Upstream(raw materials/feedstocks, medium formulation, fermentation (fermentation mode)).

describe the production of soy sauce and explain the role of each microorganism in each stage of production.

Compare and contrast downstream processing from upstream processing in industrial microbiology.

List three characteristics required of a good sewage indicator:

Although the market value of compost is negligible, many communities have implemented yard waste composting systems. Explain why?

The activated sludge process was developed from empirical knowledge and is now widely used for wastewater treatment.   From a microbial point of view,   i. Discuss how the ecology of different sectors of the process can be defined.   ii. Design an experiment to understand how an efficient process differs from   one with problems, such as sludge bulking.
