ABSTRACT:Millipede gut microbiology and decomposition of faecal pellets over a period of eight weeks were studied in the laboratory. Bacterial numbers. carbon and nitrogen content. pH and weight loss were monitored Heterotrophic bacteria were the most abundant and reached a peak in the first two weeks of decomposition The amount of carbon was constant while arnmonium nitrogen decreased from 1.51% to 0.03% after eight weeks. The pH of the pellets was slightly acidic and did not change much during the course of decomposition. A succession of micro-organisms was observecl on decomposing pellets. Zygonwcetes were replaced by Ascomycetes after 20 days of decomposition. Decomposition was significantly affected by temprature. The rate of decomposition was highest at 35°C.
