Unraveling and resolving inefficient glucolipid biosurfactants production through quantitative multiomics analyses of Starmerella bombicola strains.

Glucolipids (GLs) are glycolipid biosurfactants with promising properties. These GLs are composed of glucose attached to a hydroxy fatty acid through a ω and/or ω-1 glycosidic linkage. Up until today these interesting molecules could only be produced using an engineered Starmerella bombicola strain (∆ugtB1::URA3 G9) producing GLs instead of sophorolipids, albeit with a very low average productivity (0.

[Oculogyric crisis as an isolated extrapyramidal symptom of auto-intoxication with risperidone].

A 19-year-old female was seen at the emergency department following an auto-intoxication. An oculogyric crisis (ogc) was observed, in the absence of other extrapyramidal symptoms (eps). In a second anamnesis, patient indicated that she had taken risperidone 3 mg (an atypical antipsychotic).

Miniaturization of Starmerella bombicola fermentation for evaluation and increasing (novel) glycolipid production.

Both strain engineering and process optimization are intensively studied in microbial biosurfactant literature. However, screening of multiple strains and/or medium components in parallel is a very labor-intensive and timely process, considering the only applied technique nowadays is evaluation through shake flask and/or bioreactor experiments. Therefore, in this work, the development, optimization, and application of a more throughput technique-based on 24-deep well plates-are described for a new Starmerella bombicola strain producing bolaform sophorolipids.

Bio-based glyco-bolaamphiphile forms a temperature-responsive hydrogel with tunable elastic properties.

A bio-based glycolipid bolaamphiphile (glyco-bolaamphiphile) has recently been produced (Van Renterghem et al., Biotechnol. Bioeng.

From lab to market: An integrated bioprocess design approach for new-to-nature biosurfactants produced by Starmerella bombicola.

Glycolipid microbial biosurfactants, such as sophorolipids (SLs), generate high industrial interest as 100% biobased alternatives for traditional surfactants. A well-known success story is the efficient SL producer Starmerella bombicola, which reaches titers well above 200 g/L. Recent engineering attempts have enabled the production of completely new types of molecules by S.
