Question

Which of the following microbes is correctly paired with its function?

(a) Aspergillus niger - Production of lactic acid

(b) Trichoderma polysporum - Lowers blood cholesterol

(c) Saccharomyces cerevisiae - Production of citric acid

(d) Methanogenic bacteria - Gobar gas formation

Answer 1

Correct option (d) Methanogenic bacteria - Gobar gas formation

Explanation :

Aspergillus niger carries out fermentation to form citric acid. Fungus Trichoderma polysporum produces cyclo9sporin through formentative activity. It has antifungal, anti-inflammatory and immuno-supprressive properties. Sacchaaromyces cerevisiae (baker's yeast/brewer's yeast) is used in production of bread/alchohol. Methanogenic bacteria carry out microbial decomposition of organic matter and aids in gobar gas production.
