ganic compounds. nitrates are first converted into ammonia which combines with organic acids to form aminoacids . aminoacids are used in the systhesis of proteins, enzymes, chlorophylls, nucleic acids, etc. 3. ammonification : it is the process of releasing ammonia by certain microorganisms utilizing organic compounds derived from the dead organic remains of plants and animals and excreata of animals . the microorganisms especially involved are- actinomycetes, and bacilli (bacillus ramosus , b. vulgaris, b, mesenterilus ) oxidation of ammonia to nitrate by certain microorganisms in soil and ocean. nitrosomonas ammonia to nitrites (no, nitrobacter oxidation of the nitrites into nitrates (no). niosomonas. 2nh;} +20, —“““““_» no; +2h,0 +energy no; +20, —>+ no; + energy in ocean, ino; + o, —navacter-nirovstis_5 9 no; + energy 5. denitrification : denitrification is the reduction of nitrates back into the largely inert nitrogen gas (n;). some denitrifying bacteria are- thiobacillus denitrificants micrococcus denitrificants …
