- Microbiology Why do obligate aerobes need oxygen? (In other words why is oxygen so important to obligate aerobes)?Explain how the microbe in your selected food undergoes fermentation biochemically speaking, and how does this impacts the food quality? The example I chose for the fermented food is Yogurt.EXPERIMENT : UTILIZATION OF FOOD/AGRICULTURAL WASTE FOR PRODUCTION OF BIOETHANOL OBJECTIVE To learn on the basic process of microbial fermentation. To quantify the conversion of agricultural waste to bioethanol. Procedure: The agricultural wastes were got and then blended for 3 min. The juice was extracted by filtering using a double-fold of cotton gauze cloth, and particulate matter was removed by centrifuging at 10,000 g for 10 min at 4°C. The undiluted juice was stored, and the waste material obtained from the extraction of juice at -20°C until use. Kluyveromyces marxianus on the Yeast-Malt (YM) agar containing 10 g/L glucose, 5 g/L peptone, 3 g/L yeast extract, 3 g/L malt extract, and 20 g/L agar were maintained. Culture was prepared by inoculating two loopfuls of the fungus in a 250 mL Erlenmeyer flask with 100 mL growth medium containing 30 g/L glucose, 5 g/L yeast extract, 2 g/L NH4Cl, 1 g/L KH2PO4, 0.3 g/LMgSO47H2O. The preculture was grew on a rotary shaker at 150…
