This work was designed to find the cause of the delay in hydrogen sulfide dissimilation in Desulfotomaculum acetoxidans DSM 771, which is dependent on the sulfate uptake. This bacterium grown without addition of any aromatic compound was shown by spectrum analysis with the methylene method to contain hydroxy-benzoate derivatives. The presence of these compounds was confirmed by HPLC in fraction...

Screening cargo for illicit substances is in need of rapid high-throughput inspection systems that accurately identify suspicious cargo. Here we investigate the ability of a parasitic wasp, Microplitis croceipes to detect and respond to methyl benzoate, the volatile component of cocaine, by examining their response to training concentrations, their sensitivity at low concentrations, and their a...

Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut (Aesculus...

The anaerobic biodegradation of ferulate and benzoate in stabilized methanogenic consortia was examined in detail. Up to 99% of the ferulate and 98% of the benzoate were converted to carbon dioxide and methane. Methanogenesis was inhibited with 2-bromoethanesulfonic acid, which reduced the gas production and enhanced the buildup of intermediates. Use of high-performance liquid chromatography an...

A high-performance liquid chromatography method was applied for the determination of the levels of benzoate and sorbate in 400 food samples, including pickled cucumbers, canned tomato pastes, sour cherry jams, soft drinks, fruit juices and dairy products (UF-Feta cheeses, Lighvan cheeses, lactic cheeses, yogurts and doogh). The results showed that 270 (67.5%) of all samples contained benzoate r...

Multiple, noneliminated references ((51)Cr-labeled erythrocytes, (125)I-albumin, [(14)C]- or [(3)H]sucrose, and [(2)H](2)O), together with [(3)H]hippurate or [(14)C]benzoate, were injected simultaneously into the portal vein of the perfused rat liver during single-pass delivery of benzoate (5-1,000 microM) and hippurate (5 microM) to investigate hippurate formation kinetics and transport. The o...

The ability to degrade aromatic amines and m-toluate (Tdn+ phenotype), encoded by plasmid pTDN1, was lost from Pseudomonas putida hosts after subculture in benzoate, succinate, acetate and glucose minimal medium, the fastest rate of loss occurring where benzoate was the substrate. Tdn- cells had either lost the entire pTDN1 plasmid or suffered a recombinational deletion of a specific 26 kbp reg...

Southern root-knot nematode (Meloidogyne incognita) is an obligate, sedentary endoparasite of more than 3000 plant species, that causes heavy economic losses and limit the development of protected agriculture of China. As a biological pesticide, emamectin benzoate has effectively prevented lepidopteran pests; however, its efficacy to control M. incognita remains unknown. The purpose of the pres...

In the title compound, [Gd(C(7)H(5)O(4))(3)(H(2)O)(4)]·2H(2)O, the Gd(III) ion shows a distorted square anti-prismatic coordination formed by four aqua ligands and four O atoms from the three 2,6-dihy-droxy-benzoate (L) ligands. Two L ligands coordinate the Gd(III) ion in a monodentate mode, while the third coordinates it in a bidentate-chelating coordination mode. An extensive three-dimensiona...

Four mol-ecular salts made from hexa-methyl-ene-tetra-minium and 2-chloro-4-nitro-benzoate have been synthesized and are reported, namely ammonium hexa-methyl-ene-tetra-minium bis-(2-chloro-4-nitro-benzoate), NH4+·C6H13N4+·2C7H3ClNO4-, (I), hexa-methyl-ene-tetra-minium hydrogen bis-(2-chloro-4-nitro-benzoate), 0.5C6H13N4+·C7H3.50ClNO4-, (II), hexa-methyl-ene-tetra-minium 2-chloro-4-nitro-benzoa...
