Microbial Analysis of Compost Using Cowdung as Booster

Abstract

Microbial analysis of compost using cow dung as booster was investigated. Compost supported high population levels of bacteria with 86% of cultures tested being gram-positive and negative. The microbial identification system based on biochemical analysis identified different groups of bacteria. The microorganisms isolated and identified were Bacillus pumilus, B macereans, B. sphearicus B laterosporus, Micrococcus varians, Proteus mirabilis, Enterobacter aerogenes for bacteria, while Aspergillus rapens, A niger, A. flavus, A. fumigatus, Mucor mucedo, Rhizopus stolonifer, Varicosporium and Fusarium, were isolated for fungi. The microbial loads of the compost varies between 1.6 x 10⁶ and 1.2 x 10⁷ cfu/ml for bacteria, 5.0 x 10⁴ and 5.0 x 10⁷ cfu/ml.
