Changes in cold hardiness, carbohydrate content and β-amylase gene expression were monitored in the shoots of the highbush blueberry (Vaccinium corymbosum L.) cultivars 'Sharpblue' and 'Jersey' during cold acclimation (CA) and deacclimation (DA). The seasonal patterns were similar in both cultivars, but the levels of cold hardiness determined by electrolyte leakage analysis were significantly d...

Changes in the content of starch, protein, and RNA and in the activity of their hydrolases in the rice endosperm (Oryza sativa L., variety IR8) were determined during the first week of germination without added nutrient both in the dark and in the light. Changes were generally more rapid in the dark than in the light. Oxygen uptake and RNase activity started to increase and the root protruded o...

This study aimed to evaluate and correlate phytochemical content, antioxidant activity alpha-amylase inhibitory in aqueous acetone extract fractions derived from it (ethyl acetate fraction, watersoluble methanol fraction fraction) which are obtained Ampelocissus martini Planch. root. Ethyl had the highest total phenolic content proanthocyanidin respectively. 2,2-diphenyl-1-picrylhydrazyl, 2,2'-...

Rhizomes of Acorus calamus L. were able to maintain a functional alpha-amylase under anoxia, whereas a steep decrease in the enzyme protein content and activity took place in potato tubers. The stress-induced control in tubers occurred on the translational level. It is suggested that this decrease is one of the key factors with regard to anoxia intolerance.

The draft genome sequence of an amylase-, protease-, lipase-, oxidase-, and catalase-producing Gram-negative bacillus (Aeromonas sp. MDS8 strain MCC2167) with the ability to produce ammonia during 16 h of growth at 37°C, isolated from dairy sludge, with a size of 4,841,753 bp and a G+C content of 63.1%, is reported here.

Bacterial amylase from Bacillus subtilis and fungal amylase from Aspergillus niger were potential source for industrial exploitation in the field of amylase production. Hence, this study on bacterial amylase and fungal amylase was done to compare the kinetic parameter of both the types of amylases. 30-60% ammonium sulfate precipitation has done which showed 90 % of purification of both the part...

Tolerance to low oxygen availability is likely to be due to the interaction of several factors. Sugar availability is one of the elements required to support anaerobic metabolism. In cereal grains the availability of soluble sugars is limited, while starch is stored in large amounts. Degradation of starch under anoxia is therefore needed to avoid sugar starvation leading to rapid cell death. Th...

Haloarchaea are found at very high concentrations in salt-conditioned environments, hence produce enzymes which are able to catalyze reactions under harsh conditions, typical of many industrial processes. In the present study, culture conditions for extracellular amylase production from Haloarchaea isolated from a solar saltern were optimized and the purified enzyme was characterized. Haloferax...

Reported here is the draft genome sequence of an amylase-, protease-, DNase-, oxidase-, gelatinase-, and catalase-producing, Gram-positive diplobacillus (Bacillus sp. SM1 strain MCC2138), which was isolated from marine coastal waters and has the ability to degum raw silk fabric as well as Ramie fiber. The genome comprises 1.76 Mb with a GC content of 34.5%.
