Saccharopolyspora erythraea is a Gram-positive bacterium that can produce antibiotics. However, this microorganism must often be genetically improved for higher production before it can be used in an industrial setting. Here, we report the whole-genome sequence of the industrial hyperproducer strong mutator Saccharopolyspora erythraea strain D.

Zymomonas mobilis is a natural ethanologen with many desirable industrial biocatalyst characteristics. In this review, we will discuss work to develop Z. mobilis as a model system for biofuel production from the perspectives of substrate utilization, development for industrial robustness, potential product spectrum, strain evaluation and fermentation strategies. This review also encompasses per...

The high strain rate compressive behaviour of a Silicone elastomer: Sylgard 184® is presented. Experiments were performed over strain rates between 3000 and 15,000 s -1 , and temperatures between -40 and +73 oC, corresponding to environmental conditions in many industrial applications. An Ogden strain energy density function was fit to the data, and the strain rate and temperature dependence of...

Malolactic fermentation is essential for the deacidification of high acid grape must. We have constructed a genetically stable industrial strain of Saccharomyces cerevisiae by integrating a linear cassette containing the Schizosaccharomyces pombe malate permease gene (mae1) and the Oenococcus oeni malolactic gene (mleA) under control of the S. cerevisiae PGK1 promoter and terminator sequences i...

Genetic improvement of industrial yeast strains is restricted by the availability of selectable transformation markers. Antibiotic resistance markers have to be avoided for public health reasons, while auxotrophy markers are generally not useful for wine yeast strain transformation because most industrial Saccharomyces cerevisiae strains are prototrophic. For this work, we performed a comparati...

A genetic transformation system for an industrial wine yeast strain is presented here. The system is based on the acquisition of cycloheximide resistance and is a direct adaptation of a previously published procedure for brewing yeasts (L. Del Pozo, D. Abarca, M. G. Claros, and A. Jiménez, Curr. Genet. 19:353-358, 1991). Transformants arose at an optimal frequency of 0.5 transformant per microg...

The high lattice mismatched SiC/Si(001) interface was investigated by means of combined classical and ab initio molecular dynamics. Among the several configurations analyzed, a dislocation network pinned at the interface was found to be the most efficient mechanism for strain relief. A detailed description of the dislocation core is given, and the related electronic properties are discussed for...

This culture collection contains only non-pathogenic microorganisms contains information on strain names and special application of the particular microorganisms. This collection specializes in microorganisms valued for industrial applications, includes many patented microbes, and the company also provides oilfield and environmental services. This database provides a large set of industrial mic...

A novel 51-kb conjugative transposon of Lactococcus lactis, designated Tn6098, encoding the capacity to utilize α-galactosides such as raffinose and stachyose, was identified and characterized. Alpha-galactosides are a dominant carbon source in many plant-derived foods. Most dairy lactococcus strains are unable to use α-galactosides as a growth substrate, yet many of these strains are known to ...

BACKGROUND AND OBJECTIVES Lipases are particularly important due to the fact that they specifically hydrolyze acyl glycerol, oils and greases, which is of great interest for different industrial applications. MATERIALS AND METHODS In this study, several lipase-producing bacteria were isolated from wastewater of an oil processing plant. The strain possessing the highest lipase activity was ide...
