Which one of the following equipments is essentially required for growing microbes on a large scale, for industrial production of enzymes?
1 Sludge digester
2 Industrial oven
3 Bioreactor
4 BOD incubator
Explanation:
Bioreactor is an apparatus for growing organism (yeast, bacteria or animal cells) on a large scale. It is also used in industrial processes to produce pharmaceuticals, vaccines, or antibodies and to convert raw materials, into useful bio product. Sludge digester - Used to decompose organic waste. Industrial oven - Are heated chamber used for a variety of industrial application. BOD incubator - It is used to maintain the temperature of tissue culture.

Which of the following is correct?
1 Cyanobacteria makes mycorrhiza which absorbs phosphate form soil
2 Azotobacter is symbiotic nitrogen fixing bacteria
3 In paddy field, cyanobacteria is used to decrease soil microbes
4 Methanobacterium feed cellulose in anaerobic condition
Explanation:
Methanobacterium are strictly anaerobic bacteria. In terms of nutrition, it is an "autotrophic organism" that receives energy and carbon from decompositions products. Certain bacteria, which grow anaerobically on cellulosic material, produce a large amount of methane along with $\mathrm{CO}_2$ and $\mathrm{H}_2$. These bacteria are collectively called methanogens, and one such common bacterium is Methanobacterium. These bacteria are present in the rumen (a part of the stomach) of cattle. A lot of cellulosic material present in the food of cattle, and also present in the rumen. In the rumen, the bacteria help in the breakdown of cellulose and play an important role in the nutrition of cattle.

Which of the following is correct about biogas -
1 Methane gas is produced along with ethyl alcohol by methanogen
2 Methanogens acts on cellulose and release biogas
3 Biogas is produced by thunder and lightening
4 Maximum gas found in biogas is $\mathrm{CO}_2$
Explanation:
Methanogens act on cellulose and release biogas. Methanogens are anaerobic bacteria that grow anaerobically on cellulosic material and produce large amounts of methane along with $\mathrm{CO}_2$ and hydrogen. - One common methanogenic bacteria is Methanobacterium. Methanogens are also present in the rumen of cattle hence, the excreta (dung) can also used for biogas production.

Which of the following microbes is correctly paired with its function?
3 Saccharomyces - Production of citric cerevisiae acid
4 Methanogenic Gobar gas formation bacteria
Explanation:
Biogas (gobar gas) is a mixture of gases which can be used as fuel. Methane is the major component of biogas. It is produced when methanogens (bacteria) anaerobically digest the cellulosic material. methanogens are also present in the rumen of cattle hence, the dung can also be used for biogas (gobar gas) production. -Aspergillus niger carries out fermentation to from citric acid. - Fungus Trichoderma polysporum produces cyclosporin through fermentative activity. Cyclosporin-A used as an immunosuppressive agent in organ transplantation. - Saccharomyces cerevisiae (baker's yeast/brewer's yeast) is used in production of bread/alcohol.
