KEMAMPUAN Flavobacterium sp NUB1 DALAM MENGGUNAKAN ALIFATIK NITRIL UNTUK PERTUMBUHANNYA
Main Article Content
Abstract
A bacteria isolate capable utilizing 1% (v/v) acetonitrile and butironitrile as thesole
source of carbon and nitrogen was isolated from industrial effluents ofPT
Petrokimia-Gresik and identified as Flavobacterium sp NUB1. The bacteriaisolate
was able to grow in both acetonitrile and butironitrile at concentrationof
up to 4% (v/v). The highest growth was reached at 1% concentration ofacetonitrile
and butironitrile, but the bacteria isolate was not able to grow onacrilonitrile.
The specific growth rate (μ) of the isolate was 0,029 h-1. Themajor
objective of this study was to explore the abilities of the isolate to utilizesome
aliphatic nitriles and then further evaluate the metabolite product of thenitrile
degradation.
Key words: aliphatic nitrile, biodegradation, Flavobacterium sp. NUB1
