The alpha-proteobacterial strain Sphingobium japonicum UT26 utilizes a highly chlorinated pesticide, gamma-hexachlorocyclohexane (gamma-HCH), as a sole source of carbon and energy, and haloalkane dehalogenase LinB catalyzes the second step of gamma-HCH degradation in UT26. Functional complementation of a linB mutant of UT26, UT26DB, was performed by the exogenous plasmid isolation technique usi...

Sphingobium lucknowense F2(T), isolated from the hexachlorocylcohexane (HCH) dumpsite located in Ummari village, Lucknow, India, rapidly degrades HCH isomers. Here we report the draft genome of strain F2 (4.4 Mbp), consisting of 4,910 protein coding genes with an average G+C content of 64.3%.

introduction along with increasing population, technology has had more developments for raising the efficiency of agricultural production. modern agriculture must keep its production against destruction risk by pests. then, for maintaining the production and crops against pests and diseases, large amounts of pesticides are used each year. addition to the environment, this also threats consumers...

Here, we report the complete genome sequence of a γ-hexachlorocyclohexane (γ-HCH)-degrading bacterium,Sphingobiumsp. strain MI1205. The genome of MI1205 consists of two chromosomes and four plasmids with sizes of 33 to 292 kb. All thelingenes for γ-HCH metabolism are dispersed on the four plasmids.

Here, we report the draft genome sequence of the hexachlorocyclohexane (HCH)-degrading bacterium Sphingobium ummariense strain RL-3, which was isolated from the HCH dumpsite located in Lucknow, India (27°00'N and 81°09'E). The annotated draft genome sequence (4.75 Mb) of strain RL-3 consisted of 139 contigs, 4,645 coding sequences, and 65% G+C content.

The surface shear rheology of hydrophobin HFBII adsorption layers is studied in angle-ramp/relaxation regime by means of a rotational rheometer. The behavior of the system is investigated at different shear rates and concentrations of added β-casein. In angle-ramp regime, the experimental data comply with the Maxwell model of viscoelastic behavior. From the fits of the rheological curves with t...

BACKGROUND Few studies have evaluated predictors of childhood exposure to organochlorine pesticides (OCPs), a class of lipophilic persistent chemicals. OBJECTIVES Our goal was to identify predictors of serum OCP concentrations-hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), and p,p-dichlorodiphenyldichloroethylene (p,p´-DDE)-among boys in Chapaevsk, Russia. METHODS Between 2003 an...

It has been shown that hypercholesterolemia (HCh) exaggerates the microvascular dysfunction that is elicited by ischemia and reperfusion (I/R). The objective of this study was to determine whether oxidants contribute to the exaggerated inflammatory responses and enhanced albumin leakage observed in HCh rat mesenteric venules exposed to I/R (10 minutes of ischemia and 30 minutes of reperfusion)....

In recent years, β-Hexachlorocyclohexane (β-HCH) has been detected frequently in water, seriously threatening human health and ecological balance. To explore the effects of different treatment groups on removal β-HCH experimental water response microbial community structure system, three strains β-HCH-degrading bacteria—Ochrobactrum sp. (Och1, Och2) Pseudomonas (Pse1)—combined with Canna were s...
