Hydrotalcite derived materials are considered to be promising candidates for solid sorbents for carbon dioxide capture at intermediate temperatures (250–400 C). The recently developed organically intercalated layered double hydroxide (LDH) shows a great improvement in carbon dioxide adsorption capacity compared to alternative sorbents. However, the molecular-scale structure of this new class of...

The characteristics of L-lactic acid transport across the trophoblast basal membrane were investigated and compared with those across the brush-border membrane by using membrane vesicles isolated from human placenta. The uptake of L-[(14)C]lactic acid into basal membrane vesicles was Na(+) independent, and an uphill transport was observed in the presence of a pH gradient ([H(+)](out) > [H(+)](i...

Malathion in-vitro biodegradation study was conducted in liquid medium with five bacterial strains labeled S1, S2, S3, S4 and S5 isolated from newly reclaimed agricultural soil. Malathion residues were measured at successive intervals until 30 days after incubation, paralleled with control samples. Malathion Recovery rate was performed at 0.1 and one mg kg, achieved values were 91.30 and 98.70%...

There is an increasing interest in applying natural antimicrobial compounds in the food industry. Consumers are increasingly avoiding the consumption of foods treated with chemicals. Natural alternatives are needed to achieve a high level of safety with respect to foodborne pathogenic microorganisms [1]. The natural sanitizers, such as organic acids, have been investigated because of their bact...

We aimed to determine the effects of variations in dietary composition on equine gut microbiota and their fermentation products, and proposed that dietary modifications profoundly affect microbial ecosystems and their metabolites. Bacterial communities within the large intestine of three groups of horses were compared using oligonucleotide-RNA hybridisation methodology. Each group consisting of...

A new monocarboxylic acid ionophore antibiotic related to zincophorin, CP-78,545 (1), was found in the culture broth of Streptomyces sp. N731-45. CP-78,545 was extracted with organic solvents and purified by column chromatography. The metabolite, which is active in vitro against certain Gram-positive bacteria, as well as the anaerobe Treponema hyodysenteriae, and a coccidium Eimeria tenella, wa...
