Chemical composition of bioactive pressurized extracts of Romanian aromatic plants.
In this contribution, pressurized liquid extraction has been employed to isolate bioactive compounds from three native Romanian plants, oregano, tarragon and wild thyme, and the antioxidant capacity measured by DPPH assay was highly correlated with the amount of total phenols. Expand
Optimization of xylanase production by Streptomyces sp. P12-137 using response surface methodology and central composite design
Response surface methodology and central composite design were used to optimize a biosynthesis medium for the production of xylanases by Streptomyces sp. P12-137 in submerged fermentation culture atExpand
Extraction and characterization of volatile compounds and fatty acids from red and green macroalgae from the Romanian Black Sea in order to obtain valuable bioadditives and biopreservatives
Three species of macroalgae, Ceramium virgatum, Ulva intestinalis, and Cladophora vagabunda, harvested from the Romanian Black Sea coast, were studied as sources of valuable compounds that could be used as additives and biopreservatives. Expand
Fluorescence spectroscopy and molecular modeling investigations on the thermally induced structural changes of bovine β-lactoglobulin
Abstract The heat-induced conformational and structural changes in β-lactoglobulin were analyzed using the fluorescence techniques and the molecular modeling approach. The experimental resultsExpand
Effect of buckwheat flour and oat bran on growth and cell viability of the probiotic strains Lactobacillus rhamnosus IMC 501®, Lactobacillus paracasei IMC 502® and their combination SYNBIO®, in
Developing a new synbiotic product using the best combination of probiotics and prebiotics by promoting better growth and survival and be acceptable to the consumers with high concentration of probiotic strain is developed. Expand
Production of a novel microbial transglutaminase using Streptomyces sp. polar strains
Several biotechnological aspects regarding the increase in transglutaminase biosynthesis yield were studied. The Streptomyces sp. strains used in this study, coded MIUG 6P, MIUG 7P and MIUG 13P, wereExpand
Characterization, purification, and temperature/pressure stability of polyphenol oxidase extracted from plums (Prunus domestica)
Abstract In this study, polyphenol oxidase (PPO) was extracted from Prunus domestica and partially purified by ammonium sulfate precipitation, hydrophobic interaction chromatography, and ion exchangeExpand
Overview on Brewing Yeast Stress Factors
The environmental changes directly affect cellular activity, the ones interfering with their optimal activity or jeopardizing their life are known as stress factors. Both prokaryotes and eukaryotesExpand
Potential of newly isolated wild Streptomyces strains as agents for the biodegradation of a recalcitrant pharmaceutical, carbamazepine
The strain Streptomyces MIUG 4.89 showed an interesting efficiency for CBZ removal, with a yield of 35% when it was cultivated in submerged conditions on a minimal medium supplemented with 5 g L−1 glucose, which is promising for the use of these filamentous bacteria as bioremediation agents. Expand
Response surface optimization of experimental conditions for carbamazepine biodegradation by Streptomyces MIUG 4.89.
The response surface analysis results showed that the capacity of the selected strain Streptomyces MIUG 4.89 to degrade carbamazepine was high in submerged cultivation system by cultivation in a liquid medium containing 6.5 g L(-1) glucose and 2 g L (-1) yeast extract, inoculated at 7% (v/v) and cultivated at pH 6.0.
