MICROBIAL ECOLOGY OF PETROLEUM UTILIZATION IN CHESAPEAKE BAY
Analysis of water and sediment from two stations in Chesapeake Bay revealed four to five times the concentration of petroleum in an oil polluted site in Baltimore Harbor as compared to the control, Eastern Bay. The numbers of petroleum-degrading microorganisms in water and sediment samples were relative to the oil concentration of each sample. Total yields of petroleum-degrading microorganisms grown in an oil substrate were greater for those exposed to oil in the environment. Isolates from the oil contaminated environment produces cell yields in laboratory conditions and equaled those not previously exposed to oil at optimum growth condition. Isolates from Baltimore Harbor grew on substrates representative of aliphatic, aromatic and refractory hydrocarbons. Degradation in the Chesapeake Bay appears to be mediated by autochthorous microbial flora.
