Mannosylerythritol lipids (MELs) are biosurfactants with excellent biochemical properties and a wide range of potential applications. However, most of the studies focusing on MELs high titre production have been relying in the use of vegetable oils with impact on the sustainability and process economy. Herein, we report for the first time MELs prod...

Full-text available
Mannosylerythritol lipids (MELs) are a group of biosurfactants with a wide range of potential applications, due to their excellent tensioactive properties, biocompatibility, and biodegradability. One of the envisioned uses for MELs is in bioremediation in marine and terrestrial environments. However, knowledge regarding their ecotoxicity is limited...

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 over the pathogenic strains, owing to their GRAS status, to broaden end-applications toward the food and pharmaceutical industries. However, the incr...

Mannosylerythritol lipids (MELs) are biosurfactants with excellent biochemical properties and a wide range of potential applications. However, high production costs, low productivity and unsatisfactory scale-up production have hampered commercial adoption. Herein, we report for the first time the β-galactosidase production by Moesziomyces spp. from...
Article
Enzymes involved in xylan hydrolysis have several industrial applications. Selection of efficient microbial hosts and scalable bioreaction operations can lower enzyme production costs and contribute for their commercial deployment. This work aims to investigate Moesziomyces aphidis yeast cultivation conditions contributing for maximal xylanase titr...
Article
Full-text available
The discovery of itaconic acid as a product of citric acid pyrolytic distillation in 1837 opened the possibility of using it as a polymer building block. Itaconic acid, featuring two carboxylic acids and an unsaturated group, can potentially be used as a building block in several chemical syntheses, with a particular emphasis on polymer manufacture...
Article
Full-text available
Itaconic acid (IA), or 2-methylenesuccinic acid, has a broad spectrum of applications in the biopolymer industry owing to the presence of one vinyl bond and two acid groups in the structure. Its polymerization can follow a similar mechanism as acrylic acid but additional functionality can be incorporated into the extra beta acid group. Currently, t...

The cover image is based on the Research Article Production of mannosylerythritol lipids from lignocellulose hydrolysates: tolerance thresholds of Moesziomyces antarcticus to inhibitors by Marisa V. Santos et al., DOI: 10.1002/jctb.5853. Image Credit: Marisa V. Santos. Thanks to FCT grant CRUISE (PTDC/AAG‐TEC/0696/2014). The cover image is based on...
Article
Xylanases play a crucial role in the hydrolysis of xylan-rich hemicelluloses and have wide industrial applications in the fuel, food, feed and pulp and paper industries. The production of these enzymes at low cost is of paramount importance for their commercial deployment. Moesziomyces antarcticus PYCC 5048T and M. aphidis PYCC 5535T were screened...
Article
BACKGROUND Moesziomyces antarcticus is an efficient producer of mannosylerythritol lipids (MEL), a biosurfactant with wide range of potential applications. The use of lignocellulosic biomass can contribute to sustainable MEL production. While lignocellulosic sugars (e.g. D‐glucose and D‐xylose) can be converted to MEL, the required pretreatment of...
Poster
Enzymes cost still constitutes one of the major barriers to commercial implementation of lignocellulosic ethanol. Therefore, search for more efficient and cost-effective enzymes is desirable. Given the market availability of efficient commercial cellulases, focus should be given to novel effective xylanases to boost hemicellulose conversion. In the...

Full-text available
Agro-industrial residues are presently underused and attractive renewable resources. Recently, there has been a great interest in its use as low-cost raw materials for the production of value-added compounds as microbial enzymes. Hemicelulases have been gaining increasing attention due to its wide biotechnological applications, especially in the bi...

Full-text available
Background Mannosylerythritol lipids (MEL) are glycolipids with unique biosurfactant properties and are produced by Pseudozyma spp. from different substrates, preferably vegetable oils, but also sugars, glycerol or hydrocarbons. However, solvent intensive downstream processing and the relatively high prices of raw materials currently used for MEL p...
Article
Mannosylerythritol lipids (MEL) are glycolipid biosurfactants, produced by Pseudozyma spp., with increasing commercial interest. While MEL can be produced from d-glucose and d-xylose, the direct conversion of the respective lignocellulosic polysaccharides, cellulose and xylan, was not reported yet. The ability of Pseudozyma antarctica PYCC 5048(T)...
Article
The pentose-assimilating capacity of yeasts from the genus Pseudozyma, P. antarctica PYCC 5048T, P. aphidis PYCC 5535T and P. rugulosa PYCC 5537T, was exploited towards the production of mannosylerythritol lipids (MEL), a glycolipid with biosurfactant properties. The three strains tested were able to grow on D-xylose and L-arabinose with similar ma...
Conference Paper
Helicobacter pylori is a Gram-negative rod that colonizes the human stomach and is associated with the gastrointestinal disorders such as chronic gastritis, peptic ulcer disease, and gastric carcinoma. The over usage of the standard treatments (triple therapy) led to an increased antibiotic resistance. So far, routine antibiotic- resistance charact...
