The phenolic composition of wine is mostly determined by the accumulation compounds in grapes, as well their extraction into wine. To increase concentration yield reduction usually performed pruning, while to wines, maceration on skins extended for longer periods time. present study focuses possibilities apply both strategies improve polyphenol organic red wines Romanian variety ‘Fetească neagr...

The first reaction in the metabolism of cellobiose in Aerobad er aerogenes was shown to be adenosine 5’-triphosphatedependent phosphorylation at C-6 of the nonreducing ring to yield 6-0-phosphoryl-O-D-glucopyranosyl-(1 + 4)-D-glucase (cellobiose monophosphate). The inducible fl-glucoside kinase that catalyzes the reaction was partially purified and characterized. In addition to cellobiose, the ...

The green sulfur bacterium Chlorobium tepidum produces chlorobactene as its primary carotenoid. Small amounts of chlorobactene are hydroxylated by the enzyme CrtC and then glucosylated and acylated to produce chlorobactene glucoside laurate. The genes encoding the enzymes responsible for these modifications of chlorobactene, CT1987, and CT0967, have been identified by comparative genomics, and ...

Cosmos caudatus Kunth. or “king’s salad” contains high values of nutritional compounds that act as health promoters. Although widely consumed for its medicinal value, information on phytochemical contents and their biosynthesis in the species is scarce. Among interesting are anthocyanins possess a dual role; an antioxidant natural colorant. A complete anthocyanin biosynthetic pathway C. was elu...

Cluster zone leaf removal is a well-established viticulture practice for improving cluster microclimate and wine quality in cooler climates, while its efficacy warmer conditions less known. Here we compared the effect of early (ELR, after fruit set; diameter berries 3–5 mm) late (LLR, beginning veraison) on berry composition phenolic profile grapevine (Vitis vinifera L.) variety Cabernet Sauvig...
