The inhibitory effects of nisin, natamycin and malic acid, incorporated in whey protein films with pH 3, were investigated alone or with addition of sucrose esters, Tween80 or EDTA. Water vapour permeability measurements and mechanical and rheological tests were also assessed. EDTA and Tween80 did not significantly (P < 0.05) influence the inhibitory activity of films against Pseudomonas aerugi...
The effect of aluminum on dimorphic fungi Yarrowia lipolytica was investigated. High aluminum (0.5-1.0 mM AlK(SO(4))(2)) inhibits yeast-hypha transition. Both vanadate-sensitive H(+) transport and ATPase activities were increased in total membranes isolated from aluminum-treated cells, indicating that a plasma membrane H(+) pump was stimulated by aluminum. Furthermore, Al-treated cells showed a...
BACKGROUND Yarrowia lipolytica efficiently metabolizes and assimilates hydrophobic compounds such as n-alkanes and fatty acids. Efficient substrate uptake is enabled by naturally secreted emulsifiers and a modified cell surface hydrophobicity and protrusions formed by this yeast. We were examining the potential of recombinant Y. lipolytica as a biocatalyst for the oxidation of hardly soluble hy...
Cost effective production of biofuels depends critically on feedstock cost and availability. As such, volatile fatty acids (VFAs) can play an important role in advancing sustainable biofuel production since they can be derived from low cost feedstock including gases and municipal solid waste. To this end, we studied fermentations of the oleaginous microbe Yarrowia lipolytica engineered for lipi...
The yeast Yarrowia lipolytica is a potent accumulator of lipids, and lipogenesis in this organism can be influenced by a variety of factors, such as genetics and environmental conditions. Using a multifactorial study, we elucidated the effects of both genetic and environmental factors on regulation of lipogenesis in Y. lipolytica and identified how two opposite regulatory states both result in ...
Yarrowia lipolytica has been a valuable biotechnological workhorse for the production of commercially important biochemicals over 70 years. The knowledge gained so far on native biosynthetic pathways, as well availability numerous systems and synthetic biology tools, enabled not only regulation redesign existing metabolic but also introduction novel ones; further consolidating position yeast in...
We here report the complete nucleotide sequence of the 47.9 kb mitochondrial (mt) genome from the obligate aerobic yeast Yarrowia lipolytica. It encodes, all on the same strand, seven subunits of NADH: ubiquinone oxidoreductase (ND1-6, ND4L), apocytochrome b (COB), three subunits of cytochrome oxidase (COX1, 2, 3), three subunits of ATP synthetase (ATP6, 8 and 9), small and large ribosomal RNAs...
Diverse oleaginous yeasts can grow and accumulate lipid on a broad range of competitive substrates. In this study crude glycerol from conventional biodiesel production was used as the substrate for lipid production via oleaginous yeasts. Various cultivation conditions were tested – different C/N ratios, temperatures and addition of salts. Candida lipolytica, Yarrowia lipolytica, Trichosporon fe...
The ACO3 gene, which encodes one of the acyl-CoA oxidase isoenzymes, was isolated from the alkane-utilizing yeast Yarrowia lipolytica as a 10 kb genomic fragment. It was sequenced and found to encode a 701-amino acid protein very similar to other ACOs, 67.5% identical to Y. lipolytica Aco1p and about 40% identical to S. cerevisiae Pox1p. Haploid strains with a disrupted allele were able to grow...
The request for new flavourings increases every year. Consumer perception that everything natural is better is causing an increase demand for natural aroma additives. Biotechnology has become a way to get natural products. γ-Decalactone is a peach-like aroma widely used in dairy products, beverages and others food industries. In more recent years, more and more studies and industrial processes ...
