Cellulose degrading bacteria in termites are important plant degraders as they play an essential role in digesting cellulose for termites. This study aimed to identify cellulose degrading bacteria in termites (Macrotermites ...

PROFILING AND EVALUATION OF BACTERIAL CONSORTIA FOR EFFICIENT BIOGAS PRODUCTION IN SMALL SCALE BIODIGESTERS WITHIN UASIN-GISHU COUNTY

OSESO, FLORENCE (University of Eldoret, 2022-06)

Anaerobic digestion is a sequential biological activity that accepts the efficient capture of methane for energy production. The dependence on fossil and wood fuels as a primary energy source has led to multitudes of ...

CELLULOLYTIC ACTIVITY AND DIVERSITY OF BACTERIA ISOLATED FROM THE WHOLE BODY OF (Macrotermes michaelseni) FROM NANDI AND VIHIGA COUNTY

MIYAYO, RAHELI NEEMA (University of Eldoret, 2022-03)

The accumulation of plant waste in the environment has increased recently since plants are not easily degraded. Consequently, there is a rising demand for efficient cellulolytic bacteria that can break done cellulose ...
