Improving The Effectiveness Of Crude-oil Hydrocarbon Biodegradation Employing Azotobacter Chroococcum As Co-inoculant

Azotobacter chrococcum has a great potential as biosurfactant producing bacteria and was used as co-inoculant to promote the rate of hydrocarbon biodegradation. The rate of hydrocarbon biodegradation were 0.01212, 0.01582 and 0.01766 g/l per day for Acinetobacter sp, Bacillus cereus and the consorsium culture respectively. On the other hand, the rates of biodegradation using Azotobacter as co-inoculant were 0.1472, 0.01612 and 0.02709 g/l per day. Azotobacter chroococcum co-inoculant has the capability of increasing biodegradation efficiency of crude oil hydrocarbon. The biodegradation efficiency of petroleum hidrocarbon was increated by 13.4, 14.6 and 14.4 % within the petrobacter cultures.
