Sophorolipids (SLs) are glycolipid biosurfactants abundantly produced from different feedstocks by yeasts, and have been widely developed for various applications. In this study, we searched novel SLs, aiming to broaden the functions application range. As a result of screening based on phylogenetic information known SL producer, found that Candida batistae CBS 8550 produces new types SLs. Interestingly, present product mainly constituted acid-form SLs (more than 60% total SLs), considerably...
Mannosylerythritol lipids (MELs) are biosurfactants known for their versatile interfacial and biochemical properties. To broaden application in cosmetics, we investigated the antioxidant properties of different MEL derivatives (MEL-A, -B, -C) by using a 1,1-diphenyl-2-picryl hydrazine (DPPH) free-radical- superoxide anion-scavenging assay. All tested showed activity vitro, but at lower levels than those arbutin. Of MELs, MEL-C, which is produced from soybean oil Pseudozyma hubeiensis,...
Pseudozyma antarctica is one of the best producers glycolipid biosurfactants known as mannosylerythritol lipids (MELs), which show not only excellent surface-active properties but also versatile biochemical actions. In order to obtain a variety producers, all species genus were examined for their production MELs from soybean oil. fusiformata, P. parantarctica and tsukubaensis newly identified be MEL producers. Of strains tested, gave yield (30 g L(-1)). The obtained corresponded those...
ABSTRACT Glyceric acid (GA), an unfamiliar biotechnological product, is currently produced as a small by-product of dihydroxyacetone production from glycerol by Gluconobacter oxydans . We developed method for the efficient GA target compound new surplus applications in biodiesel and oleochemical industries. investigated ability 162 acetic bacterial strains to produce found that patterns productivity enantiomeric compositions obtained several differed significantly. The growth parameters two...
ABSTRACT The basidiomycetous yeast Pseudozyma antarctica T-34 is an excellent producer of mannosylerythritol lipids (MELs), members the multifunctional extracellular glycolipids, from various feedstocks. Here, genome sequence P. was determined and annotated. Analysis might provide insights into properties this that make it superior for use in production functional leading to further development industrial applications.
Abstract Sophorolipids (SLs) are promising glycolipid biosurfactants as they easily produced and functional. SLs from microorganisms comprised of mixtures multiple derivatives that have different structures properties, including well-known acidic lactonic SL (ASLs LSLs, respectively). In this study, we established a method for analyzing all in the products Starmerella bombicola , typical SL-producing yeast. Detailed component analyses S. were carried out using reversed-phase high-performance...
Mannosylerythritol lipids (MELs), are produced from feedstock by the genus Pseudozyma, and most promising biosurfactants known due to its versatile interfacial biochemical actions. In order broaden application in cosmetics, hair care properties of MELs were investigated using damaged hair. On electron microscopic observation, was dramatically recovered with applying MEL-A MEL-B. The tensile strength increased treatment (122.0 +/- 13.5 gf/p), MEL-B (119.4 7.6 gf/p) ceramide (100.7 15.9...
Glycolipid biosurfactants, such as mannosylerythritol lipids (MELs), are produced by different yeasts belonging to the genus Pseudozyma and have been attracting much attention new cosmetic ingredients owing their unique liquid-crystal-forming moisturizing properties. In this study, effects of MEL derivatives on skin were evaluated in detail using a three-dimensional cultured human model an vivo study. The cells treated with sodium dodecyl sulfate (SDS), SDS-damaged basis cell viability. Most...
Biosurfactants (BS) are produced by a variety of microorganisms from renewable resources, and have unique properties compared to chemical surfactants. In order attain efficient production BS low-cost materials, we focused our attention on the use sugarcane molasses. Fifteen yeast strains that known as producers were examined for productivity culture medium consisting only molasses water. Among tested, Starmerella bombicola NBRC 10243 sophorolipids (SL), which glycolipid BS. The conditions...
Mannosylerythritol lipids (MELs) are glycolipid biosurfactants produced by the yeast strains of genus Pseudozyma. These show not only excellent surface-active properties but also versatile biochemical actions. In course MEL production from soybean oil P. shanxiensis, new extracellular glycolipids (more hydrophilic than previously reported MELs) were found in culture medium. As a result structural characterization, identified as mixture 4-O-[(2′,...
