ABSTRACT The effects of API reference South Louisiana crude oil upon four larval stages of American lobster (Homarus americanus) were determined in a flow-through system. Tests were conducted with naturally-hatched animals in individual test chambers as well as in mass culture systems in an operating state lobster hatchery. Experimental flow-through crude oil exposure concentrations were 0.1, and 1.0 ppm, administered as a strongly-agitated emulsion-like mix to ambient temperature seawater ranging from 15°-20°C. Oil exposure residence times ranged from 0.8-5.6 minutes depending on the test. Exposed animals were monitored six times daily for feeding behavioral characteristics, mobility, molting success, growth and development times to reach the fourth larval stage. Pigmentation analysis was performed on individual larvae by photomicroscopy, and hydrocarbon analyses were also conducted thereon. Post-larval development through the eighth stage was investigated. Statistical comparisons were made among different control animals and between control and oil-exposed larvae.

Chesapeake Bay sediment bacteria from oil-contaminated and oil-free environments were compared for their ability to utilize a South Louisiana crude oil. Preferential solubility, column chromatography, gas–liquid chromatography, and computerized mass spectrometry were used to provide new and useful information regarding biodegradation of fractions and components of the crude oil. Vibrio, Pseudomonas, and Acinetobacter spp. were isolated from the culture inoculated with oil-contaminated sediment, whereas coryneforms and Pseudomonas spp. were isolated from the culture inoculated with oil-free sediment. Microorganisms from the oil-free sediment produced greater quantities of polar n-pentane-insoluble components (asphaltenes) after degradation, whereas microorganisms from the oil-contaminated sediments provided greater degradation of saturated and aromatic hydrocarbons.

Crude and fuel oils were compared for ability to support growth of a mixed population of estuarine bacteria. A total of four oils, two crude and two fuel oils, were examined. It was found that each of the oils supported a unique population of bacteria and yeasts, with respect to generic composition. Low-sulfur, high-saturate, South Louisiana crude oil was found to be highly susceptible to degradation. In contrast, the dense, high-sulfur, high-aromatic, Bunker C fuel oil was strongly refractory to microbial degradation.
