Glycolipid biosurfactants are the most prominent group of microbial biosurfactants, comprising rhamnolipids, sophorolipids and mannosylerythritol lipids (MELs). Usually, large amounts hydrophobic substrates (e.g., vegetable oils) used to achieve high titers (~200 g/L) a crude product low purity at values limited 50–60%, contaminated with unconsumed triacylglycerol residual free fatty acids monoacylglycerides. The methods reported for removal these contaminants use mixture organic solvents,...

Mannosylerythritol lipids (MELs), one of the most promising biosurfactants (BS), are glycolipids produced by yeasts or fungi, with great environmental performance and a high compatibility human body. MELs besides working as typical surfactants, can form diverse structures when in critical aggregation concentration (CAC), reducing surface tension water other solutions, being stable over wide range conditions. Among others, present anti-microbial, antitumor, antioxidant anti-inflammatory...

Fermentations are complex and often unpredictable processes. However, fermentation-based bioprocesses generate large volumes of data that currently underexplored. These can be used to develop data-driven models, such as machine learning (ML), improve process predictability. Among various fermentation products, biosurfactants have emerged promising candidates for several industrial applications. Nevertheless, biosurfactant large-scale production is not yet cost-effective. This study aims...

The discovery of itaconic acid as a product citric pyrolytic distillation in 1837 opened the possibility using it polymer building block. Itaconic acid, featuring two carboxylic acids and an unsaturated group, can potentially be used block several chemical syntheses, with particular emphasis on manufacture. elucidation biochemical pathways originating from first Aspergillus terreus and, recently, species Ustilago genus, has intensified diversified research focused microbe-based production,...

Research on biosurfactants (BS) is consistently increasing in the past years, driven from their beneficial attributes over chemical surfactants. Lactobacilli (LAB) and yeast BS producers could prevail pathogenic strains, owing to GRAS status, broaden end-applications toward food pharmaceutical industries. However, increased cost of production confers a bottleneck for industrial manufacture. Hence, exploitation agro-industrial waste by-products as fermentation supplements currently spotlight....

Abstract BACKGROUND Moesziomyces antarcticus is an efficient producer of mannosylerythritol lipids (MEL), a biosurfactant with wide range potential applications. The use lignocellulosic biomass can contribute to sustainable MEL production. While sugars (e.g. D‐glucose and D‐xylose) be converted MEL, the required pretreatment releases by‐products that are potentially inhibitory for yeasts.
