$II$ and $III$

Vedclass · Answer

(C) $1$. $I$ Nitrosomonas: This bacterium oxidizes $NH_3$ to nitrite,not nitrite to nitrate. Nitrite to nitrate conversion is performed by Nitrobacter.$2$. $II$ Thiobacillus: This bacterium is involved in the process of denitrification,where nitrate is reduced to nitrogen gas. This is a correct match.$3$. $III$ Nostoc: This is a cyanobacterium that acts as a free-living nitrogen-fixer. This is a correct match.$4$. $IV$ Azotobacter: This is a free-living nitrogen-fixing aerobic microbe,not anaerobic. Therefore,this is an incorrect match.Thus,$II$ and $III$ are the correct matches.

Column $I$	Column $II$
$A$. Thiobacillus	$1$. Free-living nitrogen-fixing cyanobacteria
$B$. Nitrosomonas	$2$. Denitrification
$C$. Nostoc	$3$. Free-living aerobic nitrogen-fixing bacteria
$D$. Azotobacter	$4$. $NH_{3}$ to Nitrite

Column-$I$	Column-$II$
$(a)$ Free living aerobic nitrogen fixer	$(1)$ Frankia
$(b)$ Denitrification	$(2)$ Anabaena
$(c)$ Free living anaerobic nitrogen fixer	$(3)$ Thiobacillus
$(d)$ Symbionts	$(4)$ Beijerinckia

Select the correct matches.
$I$ Nitrosomonas - Nitrite to nitrate
$II$ Thiobacillus - Denitrification
$III$ Nostoc - Free-living nitrogen-fixer
$IV$ Azotobacter - Anaerobic nitrogen-fixer
