title: Characterization of coryneform bacteria in piggery wastes.
abstract: Coryneform bacteria were found to dominate in the microflora of liquid pig manure. After longterm storage or intensive aeration, the number of these organisms began to decline. At the same time, the production of offensive odour decreased. Treatment with o-phosphoric acid and ammonium persulfate led to a decrease in both the total viable count and in the number of coryneform bacteria. The slight odour reduction is explained by the bactericidal effect of these chemicals. A numerical-taxonomic analysis of 131 coryneform organisms isolated from pig manure showed that the bacteria of the 14 taxa recovered were not closely related to recognized bacterial species. They appeared to represent hitherto undescribed species or variants of known species.
