Dynamic transition of a methanogenic population in response to the concentration of volatile fatty acids in a thermophilic anaerobic digester

Article Abstract:

The microbial community succession in a thermophilic methanogenic bioreactor under deteriorative and stable conditions induced by acidification and neutralization respectively was investigated using PCR-mediated single-strand conformation polymorphism (SSCP). The analysis indicated that the archaeal community structure was closely correlated with the volatile fatty acid (VFA) concentration.

Stable coexistence of five bacterial strains as a cellulose-degrading community

Article Abstract:

The construction of a cellulose-degrading, defined mixed culture consisting of five bacterial strains that are dominant bacteria in the original microflora is described. The characteristics of each of the members in the pure cultures are investigated and the roles and relationships among the members of the community in situ are evaluated based on these results.

Enzyme production-based approach for determining the functions of microorganisms within a community

Article Abstract:

An investigation of the relationship between the dominant members of the microbial community and their roles in the decomposition of biopolymers is made. It is also shown that these dominant members play a pivotal role as extracellular gelatinase and amylase producers during the composting process.
