Vedclass · Answer

(C) Microbes are not involved in the primary treatment of sewage,which is a physical process involving filtration and sedimentation to remove large and small particles.Secondary treatment (biological treatment) involves the growth of aerobic microbes to consume organic matter.Anaerobic sludge digesters use anaerobic bacteria to digest the sludge produced during secondary treatment.Microbes are also used in the production of various bioactive molecules such as cyclosporin $A$ and statins.Therefore,microbes are used in $2, 3,$ and $4$.

Column $I$	Column $II$ and $III$
$(a)$ Trichoderma	$(s)$ Cyclosporin $A$ - $(iv)$ Immunosuppressive agent
$(b)$ Vitamin	$(q)$ Riboflavin - $(ii)$ Vitamin
$(c)$ Monascus purpureus	$(r)$ Statins - $(iii)$ Blood cholesterol lowering agent
$(d)$ Streptococcus	$(p)$ Streptokinase - $(i)$ Clot buster

Column-$I$	Column-$II$
$(a)$ Distillation	$(1)$ Rhizobium
$(b)$ Non-distillation	$(2)$ Azotobacter
$(c)$ Symbiotic	$(3)$ Beer and Wine
$(d)$ Free-living	$(4)$ Whisky,Brandy,Rum

Microbes are used in:
$1.$ Primary treatment of sewage
$2.$ Secondary treatment of sewage
$3.$ Anaerobic sludge digester
$4.$ Production of bioactive molecules
