Anaerobic bacteria

Tinidazole (TNZ) demonstrates greater efficacy against anaerobic bacteria, particularly Gram-negative strains, compared to metronidazole. This study aimed to formulate an in situ gel containing preformed Eudragit RSPO-based nanoparticles (NPs) of TNZ and to evaluate its physicochemical properties.

Alkaline pulping liquors are the problematic for environment due to their toxicity and poor biodegradability. During last decade, anaerobic treatment technology has been successfully applied to various types of pulp and paper industry effluents. In the present study, the treatment of highly toxic pulping liquors in lab-scale has been done using sulfate reducing bacteria (SRB) isolated from sediment samples of pulp and paper mills in Vietnam. This treatment could reduce 70 - 75% of COD after three weeks. The COD removal could achieve 82 - 88% by subsequent aerobic treatment in 48 hours.

Two novel chondroitinases, chondroitin ABC lyase (EC 4.2.2.4) and chondroitin AC lyase (EC 4.2.2.5), have been purified from Bacteroides stercoris HJ-15, which was isolated from human intestinal bacteria with glycosaminoglycan degrading enzymes. Chondroitin ABC lyase was purified to apparent homogeneity by a combination of QAE-cellulose, CM-Sephadex C-50, hydroxyapatite and Sephacryl S-300 column chromatography with a final specific activity of 45.7 lmolÆmin)1Æmg)1.

In Klebsiella pneumoniae, the flavoprotein, NifL regulates NifA mediated transcriptional activation of the N2-fixation (nif) genes in response tomolecular O2and ammonium.We investigated the influence of membrane-bound oxidoreduc-tases on nif-regulation by biochemical analysis of purified NifLandbymonitoringNifA-mediated expressionofnifH¢-¢lacZ reporter fusions in different mutant backgrounds. NifL-bound FAD-cofactor was reduced by NADH only in the presence of a redox-mediator or inside-out vesicles derived from anaerobically grown K.pneumoniaecells,...

The membrane lipid composition of planctomycetes capable of the an-aerobic oxidation of ammonium (anammox), i.e. Candidatus‘Brocadia anammoxidans’ and Candidatus‘Kuenenia stuttgartiensis’, was shown to be composed mainly of so-called ladderane lipids. These lipids are com-prised of three to five linearly concatenated cyclobutane moieties withcis ring junctions, which occurred as fatty acids, fatty alcohols, alkyl glycerol monoethers, dialkyl glycerol diethers and mixed glycerol ether⁄esters. ...
