Biotransformation of alpha-, beta, gamma-, and delta-hexachlorocyclohexane under methanogenic conditions
Article Abstract:
The enrichment of an anaerobic microbial consortium reductively dechlorinates beta-hexachlorocyclohexane through tetrachlorocyclohexene, resulting in the accumulation of chlorobenzene and benzene. Other important isomers of hexachlorocyclohexane are also dechlorinated to chlorobenzene at similar (alpha) or lower rates (gamma; delta). The addition of vancomycin inhibited dechlorination, but not the addition of bromoethanesulfonic acid. It was, however, completely inhibited by pasteurization.

Population heterogeneity affects transport of bacteria through sand columns at low flow rates
Article Abstract:
Heterogeneity in the adhesion properties within the bacterial populations is a major factor in the large travel distances of bacteria through sand columns. A fraction of the percolated dilute suspensions of Pseudomonas sp. strain B13 deposited in sand columns while the remainder easily passed a second column identical to the first without much hindrance. Increased electrostatic repulsion between sand and bacteria partially reverted the deposition.
