An article on lactic acid fermentation of source separated urine

The article focus on an important topic - treatment of source separated human urine for odour control and maintaining a higher fertilizing value of urine. The experiments were carried out  in Moldova, at the laboratory scale. Fresh urine was lacto-fermented with inoculum from saurkraut juice and molasses was added as a source of carbon for lactic acid bacteria. The lacto-fermented urine was compared to untreated, stored urine as regarding the ammonium content, odour and effects on germination of radish. The application of lacto-fermentation in an urine tank of an UDDT showed tendency of pH decrease, however hydrolization was not stopped. Given that the hydrolyzed stale urine has a high buffering capacity, the lactic acid bacterial inoculum should be added to the urine storage tank of a UDDT before urine starts to accumulate there to increase the efficiency of the lactic acid fermentation.
