We assessed the relationship between growth profile and the extent of biodegradation of Escravos light crude oil by axenic and mixed bacteria cultures in a shake flask. Eleven petroleum-degrading bacteria were isolated by enrichment from oil-contaminated soils including, Pseudomonas effusa, Pseudomonas fluorescens, Pseudomonas cruciviae, Arthrobacter tumescens, Pseudomonas species, Pseudomonas tralucida, Alcaligenes metacaligenes, Micrococcus colpogenes, Bacillus badius, Nocardia paraffinae and Bacillus species. Specific growth rates of axenic cultures of the bacteria during degradation of Escravos light crude oil ranged between 0.
