- Inorganic Nitrate (N03-) contaminated the soil around their plant. Scientists developed mechanisms for removing Nitrite (N02-) from the soil, but have not found one for Nitrate (N03-). Is there any types of bacteria that could metabolize Nitrate (N03-) to give rise to Nitrite (N02-)? Indicate ALL metabolic pathways that could be used (aerobic respiration, anaerobic respiration, aerobic chemolithotrophy, and anaerobic chemolithotrophy) to carry out this reaction? Which of these reactions can oxidize or reduce inorganic materialsarrow_forwardYeast are facultative anaerobic organisms that can make ATP by aerobic respiration if oxygen is present, but are also capable of switching to fermentation under anaerobic conditions. For thousands of years, humans have used yeast, such as Saccharomyces cervesisiae, to ferment grapes (starch sugar) to make wine (alcoholic beverage). Four batches of wine were made following the contents and conditions listed in the table below, Contents and Conditions of Four Batches of Wine Yeast Solution Water Grape Solution Batch Added Container (L) (L) (L) Lid 1 40 0.0 8 оpen 2 40 0.2 8 closed 40 0.2 8. оpen 4 40 0.2 closed 9.
