We define and study the Magnus representation for homology cylinders generalizing the work of Kirk, Livingston and Wang [KLW] which treats the case of string links. Using this, we give a factorization formula of Alexander polynomials for three dimensional manifolds obtained by closing homology cylinders. We also show a relationship between the Gassner representation for string links and the Mag...

Dyes are the major toxic substances in all industrial wastewater and are highly carcinogenic to human beings and other soil and water living things. In this study, the most efficient bacterial isolate in decolorization of Basic Red 46 dye, isolate A3, was isolated and identified as Enterobacter cloacae sp. under the accession number KP202719. Different parameters such as dye concentration (100 ...

The effects of pretreatment method of cow dung compost, which was employed as natural hydrogen bacteria source, on the microbial community, population distribution of microbes and hydrogen production potential were investigated in the batch tests. The maximum hydrogen yield of 290.8 mL/L-culture appeared in the pretreated method A (infrared drying) by dark fermentation. The pretreated method of...

Biological uranium reduction was investigated using bacteria isolated from a uranium mine in Limpopo, South Africa. Background uranium concentration in soil from the mine was determined to be 168 mgkg(-1) much higher than the typical background uranium concentration in natural soils (0.30-11.7 mgkg(-1)). Therefore it was expected that the bacteria isolated from the site were resistant to U(VI) ...

We screened 313 ceftazidime-resistant Enterobacteriaceae isolates obtained in the United States from 1999 to 2004 for all three known qnr genes. A qnr gene was present in 20% of Klebsiella pneumoniae isolates, 31% of Enterobacter sp. isolates, and 4% of Escherichia coli isolates. qnrA and qnrB occurred with equivalent frequencies and, except for qnrB in enterobacters, were stable over time. qnr...

An isolate of Enterobacter sp. was obtained from the microbial community within the gut of the Anopheles gambiae mosquito, a major malaria vector in Africa. This genome was sequenced and annotated. The genome sequences will facilitate subsequent efforts to characterize the mosquito gut microbiome.

Enterobacter sp. Sa187 is a plant endophytic bacterium, isolated from root nodules of the desert plant Indigofera argentea, collected from the Jizan region of Saudi Arabia. Here, we report the genome sequence of Sa187, highlighting several genes involved in plant growth-promoting activity and environmental adaption.

Enterobacter sp. strain ODB01, which was isolated from the Changqing oil field, can degrade crude oil efficiently and use crude oil as its sole source of carbon and energy. We report the complete genome sequence of ODB01. The results promote its application in the remediation of petroleum contaminants.

A novel compound 2-(2-ethoxyphenyl)-5-hydroxy-1-(2-hydroxyethyl)-5-methyl piperidin-4-one (II) has been synthesized by a previously well-known reaction between (E)-3-(2-ethoxyphenyl)-1-(2-methyloxiran-2-yl)prop-2-en-1-one (I) and ethanol amine. The was used to synthesize (Z)-2-((2S,5S)-2-(2-ethoxyphenyl)-5-hydroxy-1-(2-hydroxyethyl)-5-methylpiperidin-4-ylidene)hydrazine-1-carbothioamide (III) t...
