Research Abstract

porpose : In our university, usually workmen incinerate animal feces and garbage, but we intend to exchage useful material from disposal of animal feces and garbage with some kinds of the purchased microorganisms.
sampling : our facilities have been making the most of that advantage because of getting animal feces in each animal house, then they were weighed and treated.
machine : We set the apparatus of rapid, good conditioned fermentation by microbial decomposition (N.I.Tecnosales Co.Tokyo).
results : In 7 times sampling (2 weeks) 112kg of feces and garbage from the rabbit, guinea pig and rat rooms. After 2 weeks we get about 70kg of decomposition, materials from other animals also derived almost same results. During these phenomena began we have bad-smelling around of the apparatus, I don't check these offensive odor clearly, I guess some compounds for example ammonia, hydrogen sulfide, methyl mercaptan etc.
It is very important that when we start this type of treatment we need to take a measure to meet the situation of deodorization.
