Insights on Anabaena sp. PCC 7120 Responses to HCH Isomers: Tolerance, Degradation, and Dynamics on Potential lin Genes Expression.

ABSTRACT: Hexachlorocyclohexane (HCH) was extensively used as a pesticide until the 1990s. It was synthesized by benzene photochlorination, resulting in a mixture of stereoisomers, which included α-, β-, γ-, and δ-HCH, among others. It was later discovered that only the γ-HCH isomer (also called lindane) had insecticidal properties, so it began to be purified from this mixture, while the remaining HCH isomers (representing around 85%-90% of industrial HCH production) were disposed of in dumpsites, generating environmental issues. Several works have studied microbial-driven biodegradation and physiological responses to γ-HCH, but information concerning the other isomers is scarce. Since previous research showed that the cyanobacterium Anabaena sp. PCC 7120 is effective at removing lindane; this study
