BACKGROUND High-temperature fermentation technology with thermotolerant microbes has been expected to reduce the cost of bioconversion of cellulosic biomass to fuels or chemicals. Thermotolerant Kluyveromyces marxianus possesses intrinsic abilities to ferment and assimilate a wide variety of substrates including xylose and to efficiently produce proteins. These capabilities have been found to e...

DNA microarrays of 86 genes from the yeasts Debaryomyces hansenii, Kluyveromyces marxianus, and Yarrowia lipolytica were developed to determine which genes were expressed in a medium mimicking a cheese-ripening environment. These genes were selected for potential involvement in lactose/lactate catabolism and the biosynthesis of sulfur-flavored compounds. Hybridization conditions to follow speci...

We determined the genome sequence of the thermotolerant yeast Kluyveromyces marxianus strain NBRC1777. The genome of strain NBRC1777 is composed of 4,912 open reading frames (ORFs) on 8 chromosomes, with a total size of 10,895,581 bp, including mitochondrial DNA.

Kluyveromyces marxianus TISTR 5925, isolated from rotten fruit in Thailand, can ferment at pH 3 at temperatures between 42 and 45 °C. Bioethanol production from cassava pulp using the simultaneous saccharification and fermentation (SSF) process was evaluated and compared with the separated hydrolysis and fermentation (SHF) process using K. marxianus TISTR 5925. The ethanol concentrations obtain...

anti-microbial effects of the lactic acid bacteria have been studied and proved in various investigations. this investigation aimed to study the anti-yeast effect of two isolated lactic acid bacteria species from “chal” (a product from yogurt) as biological preservatives in doogh. to do so, anti-yeast activity of l. brevis and e. faecium against saccharomyces cerevisiae, kluyveromyces. marxianu...

In the present study Kluyveromyces marxianus isolated from paneer whey was employed for biomass production. Various parameters like pH, temperature and nitrogen source were optimized for maximum biomass yield. The biomass yield was studied to vary with different nitrogen sources, pH and temperature. Ammonium sulphate, ammonium nitrate, beef extract and yeast extract were used as nitrogen source...

The use of flocculating yeast strains has been considered as a convenient approach to obtain high cell densities in bioreactors with increasing productivity in continuous operations. In Kluyveromyces marxianus ATTC 10022, the GAP1 gene encodes an isoform of glyceraldehyde-3-phosphate dehydrogenase-p37-that is accumulated in the cell wall and is involved in flocculation. To test the use of p37 a...

Bu çalışmada, Düzce ilinden toplanan Lamiaceae familyasına ait Teucrium chamaedrys L. subsp. bitkisinden elde edilen etanol, etil asetat ve kloroform ekstraktları Escherichia coli, Streptococcus pyogenes, Proteus vulgaris, Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Salmonella typhimurium, Bacillus cereus subtilis gibi bakteri kültürlerine Candid...

Biomass of Kluyveromyces marxianus was used to prepare feed formulations for ornamental fish-black mollies (Poecilia latipinna). The cytotoxicity of the fungal biomass was studied using 3T3 cell lines. Three different formulations of the biomass were used in the feeding trial. Formulation I was prepared as 100% dry cells, formulation II was prepared as 50% dry cells+50%starch and Formulation II...

Novel antihypertensive peptides released by Kluyveromyces marxianus from bovine lactoferrin (LF) have been identified. K. marxianus LF permeate was fractionated by semipreparative high performance liquid chromatography and 35 peptides contained in the angiotensin I-converting enzyme (ACE)-inhibitory fractions were identified by using an ion trap mass spectrometer. On the basis of peptide abunda...
