Pengaruh Ph Terhadap Pembentukan Etanol Pada Tahap Asidogenesis Pengolahan Po…

ABSTRACT Palm mill oil effluent potential as a source of ethanol formation substrate with a total COD content of 32,000 mg / L. The pH value is very mempemgaruhi asidogenesis stage in the anaerobic process.Specific pH range would affect the dominant bacteria that work in the fermentation process to produce ethanol and cause changes in the activity of microorganisms and exert significant in…
