This study investigated the fermentability of hemicellulosic hydrolysates obtained by intensified steam explosion pretreatment switchgrass (Panicum virgatum) and Eucalyptus globulus. Xylitol carotenoids were high-value molecules produced fermentation. The allowed to process a large amount biomass per unit time resulted in containing high sugars, among which, significant fraction was form oligom...

The subject of this study was to investigate lactic acid bacteria (LAB) and yeasts microbiota traditional sourdough (n = 36) indicate characteristics enriched that is produced from combinations isolates. A total 60 LAB 40 were identified by matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry (MALDI-TOF MS) analysis. dominant microflora Lactobacillus brevis (43.33%), Ped...

The Kluyveromyces marxianus yeast recently has gained considerable attention due to its applicability in high-value-added product manufacturing. In order intensify the biosynthesis rate of a target product, reaching high biomass concentrations reaction medium is mandatory. Fed-batch processes are an attractive and efficient way how achieve cell densities. However, depending on physiology partic...

Pectinolytic yeasts, Saccharomyces marxianus, S. bayanus, S. cerevisiae var. ellipsoideus, and Schizosaccharomyces sp., predominated in the natural fermentation of coffee cherries of Coffea robusta variety grown in Chikmagalur district of Mysore State, India. These yeast species were found on the cherry surfaces, and evidence was adduced to show that the natural fermentation of coffee was the r...

The aim of the study was to determine the optimum conditions for brown pigment formation by Kluyveromyces marxianus and Streptomyces chibaensis. Pigment formation was followed during the time course experiment in medium contains 20 g/l D-xylose as carbon source, 12 g/l of a mixture of peptone and yeast extract as a nitrogen source at pH 5.0 when incubated at 32°C, the production of pigment reac...

Abstract Background ?-Nicotinamide mononucleotide (NMN) is the direct precursor of nicotinamide coenzymes such as NAD + and NADP , which are widely applied in industrial biocatalysis especially involving cofactor-dependent oxidoreductases. Moreover, NMN a promising candidate for medical uses since it considered to be beneficial improving health aged people who usually suffer from an insufficien...

The present study was conducted to investigate the influence of initial sucrose concentration, pH and aeration rate on biomass and inulinase production by Kluyveromyces marxianus var. bulgaricus in a stirred batch reactor. Maximum inulinase activity (15.29 UmL) was obtained at a sucrose concentration of 10 g L, pH 5.0 and aeration rate of 1 vvm. The 20 g L sucrose concentration was suitable for...
