Sophorolipids are surface-active compounds synthesized by a selected number of yeast species. They have been known for over 40 years, but because of growing environmental awareness, they recently regained attention as biosurfactants due to their biodegradability, low ecotoxicity, and production based on renewable resources. In this paper, an overview is(More)
This review covers the production, properties and applications of the biopolysaccharide dextran; this biopolymer can be produced via fermentation either with Leuconostoc mesenteroides strains and other lactic acid bacteria or with certain Gluconobacter oxydans strains. The former strains convert sucrose into dextran with the dextransucrase enzyme whereas(More)
Lactobacillus amylovorus LMG P-13139, isolated from corn steep liquor, produces two bactericidal peptides with respective estimated molecular masses of 4.5 and 6.0 kDa upon denaturing sodium dodecyl sulfatepolyacrylamide gel electrophoresis. The antimicrobial activity detected in the fermentation supernatant fraction of L. amylovorus LMG P-13139 was heat(More)
Pediocin PD-1, produced by Pediococcus damnosus NCFB 1832, is inhibitory to several food spoilage bacteria and food-borne pathogens. However, pediocin PD-1 is not active against other Pediococcus spp. and differs in this respect to other pediocins produced by Pediococcus acidilactici and Pediococcus pentosaceus. Production of pediocin PD-1 starts during(More)
Microbial metabolomics has received much attention in recent years mainly because it supports and complements a wide range of microbial research areas from new drug discovery efforts to metabolic engineering. Broadly, the term metabolomics refers to the comprehensive (qualitative and quantitative) analysis of the complete set of all low molecular weight(More)
A production process for ectoine has been developed, using Brevibacterium epidermis DSM20659 as the producer strain. First, the optimal conditions for intracellular synthesis of ectoine were determined. The size of the intracellular ectoine pool is shown to be dependent on the external salt concentration, type of carbon source, and yeast extract(More)
Certain strains of Gluconobacter oxydans have been known since the 1940s to produce the enzyme dextran dextrinase (DDase; EC2.4.1.2)—a transglucosidase converting maltodextrins into (oligo)dextran. The enzyme catalyses the transfer of an α1,4 linked glucosyl unit from a donor to an acceptor molecule, forming an α1,6 linkage: consecutive glucosyl transfers(More)
The production of d-ribose by fermentation has received much attention lately, possibly because of the use of this pentose to synthesize antiviral and anticancer drugs. This review briefly outlines the methods that have been used to synthesize d-ribose since it was identified in yeast RNA, and focuses in particular on the latest developments in d-ribose(More)
