Abstract
The present invention relates to a consortium of Nitrosomonas eutropha and Nitrobacter winogradskyi, which is more effective at removing ammonia and nitrite than the commonly used consortium of Nitrosomonas europea and Nitrobacter winogradskyi, particularly in aquaculture such as shrimp ponds. Supplementation of the consortium in aquaculture such as shrimp ponds may lead to an increase in total yield, an increase in size, a decrease in Food Conversion Ratio (less food required per kg of shrimp obtained), and an increase in total per pond sales.
