the rapidly increasing interest in functional materials with reversibly switchable physico- chemical properties has led to significant work on the development of stimuli responsive membranes. thermotropic liquid crystals with their exceptional properties have potentials for drug-delivery applications. thermoresponsive liquid-crystal-embedded membranes were investigated for the purpose of develo...

background: weissellicin 110 is the only bacteriocin reported in weissella cibaria up to now. this bacteriocin represents several unique features. this is the first report on the gene sequence that encodes for the bacteriocin.objectives: providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives.material...

the potential of bulk starter fermentation strategy for production of a cost-effective and safe source of β-galactosidase was investigated. three different bulk starter media with different compositions were selected, and an industrial yogurt starter culture strain, l. bulgaricus dsm 20081 was cultivated in these media under ph-controlled conditions (ph=5.6) at 43°c. the media consisted of 1) b...

Both enantiomers of lactic acid, l-lactic acid and d-lactic acid, can be produced in a sustainable way by a photosynthetic microbial cell factory and thus from CO2, sunlight, and water. Several properties of polylactic acid (a polyester of polymerized lactic acid) depend on the controlled blend of these two enantiomers. Recently, cyanobacterium Synechocystis sp. strain PCC6803 was genetically m...

Many drugs can cause unexpected muscle disorders, often necessitating the cessation of an effective medication. Inhibition of monocarboxylate transporters (MCTs) may potentially lead to perturbation of l-lactic acid homeostasis and muscular toxicity. Previous studies have shown that statins and loratadine have the potential to inhibit l-lactic acid efflux by MCTs (MCT1 and 4). The main objectiv...

Utilization of genistein as a natural inhibitor was studied alone and in combination with conventional treatments on melanosis and microbial quality of fresh L. vannamei during 10 days ice storage. Treatments were as followed: A (dipping samples in distilled water), B (dipping in 1.25 % sodium metabisulphite solution), C (dipping in 0.01 % genistein + 2% glycerol solution), D (dipping in 0.1 % ...

SO-CAETID fermentation lactic acids are generally believed to be inactive, since it was ascertained by Phelps & Palmer [1917] and Pederson et al. [1926] that optically inactive lactic acid was produced in many natural fermentations. The lactic acid in Sake was found to be the inactive form, although not only inactive lactic acid-producing organisms (Lactobacillus sake), but also optically activ...

Stereospecificity of Some Invertebrate Lactic Dehydrogenases by Mary Jacobs Scheid 1. It has been assumed that only among unicellular organisms did nicotin¬ amide adenine dinucleotide (NAD)-linked lactic dehydrogenases occur. All higher animals were thought to possess Lspecific lactic dehydro¬ genases. It was discovered recently, however, that many species of invertebrates possess lactic dehydr...

Probiotic fermented sausages are safe and healthy meat products. Semi-dry fermented sausages were manufactured from camel meat inoculated with Lactobacillus casei and Lactobacillus paracasei and control. All treatments were analyzed for the  physico-chemical characteristics (Protein, Moisture, Fat, Ash, Lactic acid value and pH), microbiological features (total aerobic, total mold and yeast...

In this study, lactic acid production by repeated batch fermentation using cell entrapped methods was compared. Barium alginate beads, agar gel and polyurethane foam cubes were employed as carriers to immobilize Lactobacillus casei subsp. casei for the purpose of L (+)-lactic acid production. Increasing concentrations of lactic acid during fermentation were better tolerated by barium alginate e...
