abstract={Analysis of the bacterial genera associated with the rhizosphere of <i>Cyperus</i>sp., <i>Parkia</i>sp., <i>Panicumpariflorium, Zea mays, Elaeisguineensis</i><i> </i>inpetroleum hydrocarbon contaminated soil in Ugada, Imo State, Nigeria was done. The study shows that densities of total culturable heterotrophic and hydrocarbon-utilizing bacteria varied with the type of plant and were higher in the contaminated rhizosphere than in the contaminated bulk soil (non- rhizosphere) of all the plants. Unlike the result of total culturable heterotrophic counts in the bulk soil, the mean counts of the hydrocarbon-utilizing bacteria were higher in the contaminated bulk soil for all plants. <i>Elaeisguineensis</i>, gave the lowest mean counts for both total culturable heterotrophic and hydrocarbon-utilizing bacteria of all the plants studied, this may be as a result of some of the plant¡¯s exudates not stimulating all the bacterial community. Statistical analysis showed no significant difference (P>0.05) between the rhizosphere and bulk of total culturable heterotrophic and hydrocarbon-utilizing bacterial counts in both contaminated and uncontaminated soils. The hydrocarbon-utilizing bacterial genera isolated and identified were <i>Acinetobacter</i>, <i>Arthrobacter</i>, <i>Alcaligenes, Bacillus, Flavobacterium, Micrococcus, Pseudomonas</i> spp. These isolates were able to grow on petroleum hydrocarbon at different growth rates indicating that they can be used as seeds for bioaugmentation during remediation of petroleum contaminated soil.},
