The magnitude and diversity of the microbial population associated with coffee processing wastes viz., coffee pulp waste and coffee processing waste water was assessed. The anaerobic diversity was studied by an enrichment culture technique. The high C/N ratio of coffee pulp waste promoted more microbial diversity than coffee processing waste water. The distribution pattern of diversified groups revealed an order of bacteria > yeast >fungi in coffee pulp waste and bacteria > fungi > yeast in coffee processing waste water. Moreover, anaerobic population showed a significant positive correlation with the total microbial biomass in the enrichment culture throughout the enrichment process. With steady and maximum biogas production on 30th day the methanogens occupied 2.18% of the total anaerobic population, 0.4% of each cellulolyzers and tannin degraders, 0.3% of pectinolyzers and 0.53% of acid formers. The different morphotypes were identified as majority belonging to the genera Clostridium, Methanosarcina sp., Methanococcus, Methanothrix etc. These results further suggest a significant linkage between the microbial community dynamics and function in the enriched coffee processing wastes over time. This can be further exploited for commercial generation of energy by biomethantion process from coffee processing wastes.
