Your first assignment is to provide information to the firm bigmoney inc, a chemical producer in kansas interested in using microbes to clean toxic spills (bioremediation). bigmoney inc. has had a major spill of inorganic nitrite (n02-) that contaminated the soil around their plant. scientists at bigmoney have developed mechanisms for removing nh4+ from soil, but have not found one for n02-. they want to know on a strictly theoretical basis (regardless of whether bacteria exist in nature that actually do these specific reactions) if there are any types of bacteria that could metabolize n02- to give rise to nh4+? nitrite (n02-) to ammonium (nh4+).a) is this an oxidation or reduction? b) is n02- acting as an electron acceptor or donor?

Bacteria that  metabolize NO2- to give rise to NH4+ belongs to the family of denitrifying bacteria and nitrate ammonification bacteria such as pseudomonas.

Explanation:

Denitrifying bacteria uses NO2- as electron aceeptor thus converting the nitrite ion (NO2-) to ammonium ion(NH4+).

              a) The above reaction is a reduction reaction because NO2- or nitrite ion accept electron to generated its reduced form known as ammonium(NH4+).

             b)  NO2- acting as electron acceptor in this reaction.

while some business owners prefer manual record keeping systems, most businesses use an electronic record keeping system - making it easier to capture information, generate reports and meet tax and legal reporting requirements.
