“…Measurements of the persistence of organochlorine insecticides in soil have .been reported by a number of workers (Lichtenstein et al, 1971a,b;Nash and Woolson, 1967;Stewart and Fox, 1971; Young and Rawlins, 1958;Voerman and Besemer, 1970). Earlier data were summarized by Edwards (1966).…”

INSECTICIDE LOSS FROM FIELD SOILS lulose fraction of wheat and rice straw was actually in the carbon atoms of glucose, the cellulose isolated from the rice or wheat treated with nitrofen-14C was hydrolyzed and the resulting glucose was derivatized to the osazone. The osazone was then recrystallized to a constant specific radioactivity and identified by infrared spectrophotometry.The radioactivity present in the pure osazones from both rice and wheat was significantly high enough to conclude that a limited amount of conversion of the carbon atoms of nitrofen-14C into glucose and cellulose had occurred.By dividing the specific radioactivity of the cellulose by the specific radioactivity of the original rice or wheat straw and multiplying by the percent of crude fiber (cellulose) in the cereal straw, the percent of radioactive residues as cellulose at harvest was calculated. Table IV contains data from such calculations.It can be seen that only preemergence nitrofen treated rice straw has any large amount of radioactive residue in the cellulose. Postemergence-treated rice straw as well as preemergence wheat straw contained little radioactivity in the cellulose. SUMMARYIt is apparent that rice and wheat can metabolize nitrofen-14C in such a way as to produce a lignin fraction

“…environments, such as soil, sediment and groundwater (Vogel et al, 1987). HCH isomers have been found to persist in some environments for more than 15 years (Voerman & Besemer, 1970). Nevertheless, lindane biodegradation has been observed in both anaerobic and aerobic ecosystems (Bhuyan et al, 1992;Jagnow et al, 1977;Wada & Peel, 1989).…”

Lindane-degrading activity under aerobic conditions has been observed in two bacterial strains : UT26, phenotypically identified as Sphingomonas paucimobilis, and a new single unidentified isolate named RP5557T. The rrs (165 rDNA) sequences for both strains and the phenotypic characteristics for the unidentified isolate RP5557T were determined. RP5557T does not have high identity (less than 90% in all cases) with any sequence in the GenBank or RDP databases. A phylogenetic analysis based on rrs sequences indicated that RP5557T belongs to the y-Proteobacteria in a coherent phylum that includes the genera Xanthomonas and Xy/e//a (1 00 O/ O bootstrap), whereas UT26 is clearly separate from the Xanthomonas cluster. Based on the phylogenetic analyses and on the phenotypic characteristics, a new genus, Rhodanobacter, containing a single species, Rhodanobacter lindaniclasticus, is proposed for strain RP5557T (= LMG 183853, which becomes the type strain.

“…Half-life of BHC was found to be about 2 years after its incorporation deep into the soil [63]. Voerman and Besemer [64] found 3-8% of the applied lindane in soil after 15 years. However, Stewart and Fox [65] could not detect any lindane residues 12 years after surface spray application of Nova Scotian soils in Canada.…”

Genetic manipulations of microorganisms for the degradation of hexachlorocyclohexane

Hexachlorocyclohexane (HCH) is an organochlorine insecticide which has been banned in technologically advanced countries. However, it is still in use in tropical countries for mosquito control and thus new areas continue to be contaminated. Anaerobic degradation of HCH isomers have been well documented but until recently there have been only a few reports on aerobic microbial degradation of HCH isomers. The isolation of these microbes made it possible to design experiments for the cloning of the catabolic genes responsible for degradation. We review the microbial degradation of HCH isomers coupled with the genetic manipulations of the catabolic genes. The first part discusses the persistence of residues in the environment and microbial degradation while the second part gives an account of the genetic manipulations of catabolic genes inw)lved in the degradation.
