Abstract

In some embodiments, methods of controlling microbial contamination in fermenters, feedstocks and water, which is deleterious to fermentation, involving the use of peracetate oxidant solutions designed to generate reactive oxygen species. The methods may include providing a peracetate oxidant solution. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1.
