The rhizospheres and phyllospheres of peas, beans, tomatoes, and squash raised in a desert sand soil mixed with 0.5% crude oil were rich in oil-utilizing bacteria and accommodated large numbers of free-living diazotrophic bacteria, with potential for hydrocarbon utilization. According to their 16S rRNA-sequences, the cultivable oil-utilizing bacteria were affiliated with the following genera, arranged in decreasing frequency: Bacillus, Ochrobactrum, Enterobacter, Rhodococcus, Arthrobacter, Pontola, Nocardia, and Pseudoxanthomonas. Diazotrophic isolates were affiliated with Rhizobium, Bacillus, Rhodococcus, Leifsonia, Cellulosimicrobium, Stenotrophomonas, Kocuria, Arthrobacter, and Brevibacillus. The crude oil-utilizing and diazotrophic isolates grew, with varying growth intensities, on individual aliphatic (C-8 to C-40) and aromatic hydrocarbons, as sole sources of carbon and energy. Quantitative gas liquid chromatographic measurements showed that representative bacterial isolates eliminated pure n-hexadecane, n-decosane, phenanthrene, and crude oil from the surrounding liquid media. Cultivation of oily sand-soil samples with any of the four tested crops led to enhanced oil degradation in that soil, as compared with the degradation in uncultivated oily sand-soil samples.
