The objective of this research was to isolate bacteria able to utilize glycerol as carbon source and study the optimal condition of 1,3-propanediol production from crude glycerol. The bacteria B-2, B-4 and B-7 could grow and produce 1,3-propanediol in basal medium formula 1,2 and 3 that containing glycerol as energy and carbon sources. The bacteria B-2 produced highest 1,3-propanediol in basal medium formula 2. In addition, the various factors that influenced to crude glycerol fermentation in basal medium formula 2 by the bacteria B-2 were investigated. It was found that the optimal conditions of 1,3-propanediol production were 10% bacterial inoculums and crude glycerol about 50 g/L was added. pH of basal medium was adjusted around 7 and the bacterial culture was incubated at 30°C with shaking at 100 rpm for 3 days. The highest yield of 1,3-propanediol was obtained about 0.4167 g/L.

The effects of surfactant physicochemical properties, such as the hydrophile-lipophile balance (HLB) and molecular structure, on the biodegradation of 2% w/v Bow River crude oil by a mixed-bacterial culture were examined. Viable counts increased 4.6-fold and total petroleum hydrocarbon (TPH) biodegradation increased 57% in the presence of Igepal CO-630, a nonylphenol ethoxylate (HLB 13, 0.625 g/L). Only the nonylphenol ethoxylate with an HLB value of 13 substantially enhanced biodegradation. The surfactants from other chemical classes with HLB values of 13 (0.625 g/L) had no effect or were inhibitory. TPH biodegradation enhancement by Igepal CO-630 occurred at concentrations above the critical micelle concentration. When the effect of surfactant on individual oil fractions was examined, the biodegradation enhancement for the saturate and aromatic fractions was the same. In all cases, biodegradation resulted in increased resin and asphaltene concentrations. Optimal surfactant concentrations for TPH biodegradation reduced resin and asphaltene formation. Chemical surfactants have the potential to improve crude oil biodegradation in complex microbial systems, and surfactant selection should consider factors such as molecular structure, HLB, and surfactant concentration.Key words: mixed culture, crude oil, surfactant, hydrophile-lipophile balance, biodegradation.
