TEMPERATURE AND PH DEPENDENCE ACTIVITY OF CRUDE ALCOHOL DEHYDROGENASE ISOLATED FROM YEAST (Saccharomyces cerevisiae) OF Raphia hookeri AND Elaeis guineensis SAPS IN SELECTED LOCATIONS IN NIGER DELTA REGION OF NIGERIA

Alcohol dehydrogenase (E.C 1.1.1.1) is an enzyme that catalyses the reduction of acetaldehyde to ethanol during fermentation. In this study, activity crude alcohol (ADH) isolated from yeast (Saccharomyces cerevisiae) fresh Raphia hookeri and Elaeis guineensis palm wine(saps) Niger Delta region (Akwa Ibom, Bayelsa, Cross River, Delta, Edo, Imo River States) was determined at a temperature range 25-70°C pH 5.0-9.0. The results showed yeasts both R. E. saps increased in all states as 25-30oC but decreased with further increase 40-700C. optimum recorded 300C for locations, ADH State exhibiting highest (0.00025?mole/min). study also various temperatures (30 -70°C), activities sap were higher than those sap. locations increasing till 8.0 declined markedly 9.0. A similar trend observed states.The found be across locations. It concluded S. cerevisae Niger-Delta Nigeria could applied by alcohol-producing industries alcoholic fermentation 30°C 8.0, especially yeasts.
