Unformatted text preview: ESTED FROM SULFUR, NOT AS MUCH AS GLUCOSE. IN ANAEROBIC RESP, NOT AS MUC NRG AS AEROBIC RESP. C, N & S cycles SULFUR CYCLE: CHEMOAUTOTROPHS TAKE REDUCED FORM OF SULFUR, OXIDIZE IT AND PRODUCE NRG IN PROCESS. ORGANISMS THAT RESPIRE AEROBICALLY: USE OXIDIZED SULFUR AS TERMINAL ELECTRON ACCEPT IN ANAEROBIC RESPIR EX: IN MUDFLATS, SULFUR ODOR PRODUCED BY MO'S THAT PRODUCE H2S AND OTHER ORGS THAT OXIDIZE H2S NRG CAN BE HARVESTED FROM SULFUR, NOT AS MUCH AS GLUCOSE. IN ANAEROBIC RESP, NOT AS MUC NRG AS AEROBIC Read about C, N & S cycles REDUCED FORM OF NITROGEN: NITRATE AND NITRITE, MO'S GET NRG FROM NITRIFICATION, ORGANISMS GET NRG FROM OXIDIZING INROGANIC COMPOUND. ASSIMILATORY METABOLISM: TAKE NITROGEN FROM ENVIMNT, BUILD IT INTO CELL MATERIAL; 1.NITRATE REDUCTION TO MAKE CELL FUEL (ONLY MO'S) 2. NITROGEN FIXATION: NITROGEN FROM ATMOSPHERE CAN ONLY BE MADE INTO ORGANIC MATERIAL BY BACTERIA. OTHERWISE NITROGEN WOULD GET STUCK IN AIR AS NITRATE OR NITROGEN GAS MAKING IT UNAVAILABLE FOR HUMAN USE NO3 NO2 Classification of Microbes Taxonomy: The study of s...
