Abstract
Background L-(+)-tartaric acid (L-TA) is an important organic acid, which is produced from the cream of tartar or stereospecific hydrolysis of the cis-epoxysuccinate. The former method is limited by the availability of raw material and the latter is dependent on the petrochemical material. Thus, new processes for the economical preparation of L-TA from carbohydrate or renewable resource would be much more attractive. Production of 5-keto-D-gluconate (5-KGA) from glucose by Gluconobacter oxydans is the first step to produce L-TA. The aim of this work is to enhance 5-KGA accumulation using combinatorial metabolic engineering strategies in G. oxydans. The sldAB gene, encoding sorbitol dehydrogenase, was overexpressed in an industrial strain G. oxydans ZJU2 under a carefully selected promoter, P0169. To enhance the efficiency of the oxidation by sldAB, the coenzyme pyrroloquinoline quinone (PQQ) and respiratory chain were engineered. Besides, the role in sldAB overexpression, coenzyme and respiratory chain engineering and their subsequent effects on 5-KGA production were investigated. Results An efficient, stable recombinant strain was constructed, whereas the 5-KGA production could be enhanced. By self-overexpressing the sldAB gene in G. oxydans ZJU2 under the constitutive promoter P0169, the resulting strain, G. oxydans ZJU3, produced 122.48 ± 0.41 g/L of 5-KGA. Furthermore, through the coenzyme and respiratory chain engineering, the titer and productivity of 5-KGA reached 144.52 ± 2.94 g/L and 2.26 g/(L · h), respectively, in a 15 L fermenter. It could be further improved the 5-KGA titer by 12.10 % through the fed-batch fermentation under the pH shift and dissolved oxygen tension (DOT) control condition, obtained 162 ± 2.12 g/L with the productivity of 2.53 g/(L · h) within 64 h. Conclusions The 5-KGA production could be significantly enhanced with the combinatorial metabolic engineering strategy in Gluconobacter strain, including sldAB overexpression, coenzyme and respiratory chain engineering. Fed-batch fermentation could further enlarge the positive effect and increase the 5-KGA production. All of these demonstrated that the robust recombinant strain can efficiently produce 5-KGA in larger scale to fulfill the industrial production of L-TA from 5-KGA.

Abstract
The ascomycete fungus Beauveria bassiana is a pathogen of hundreds of insect species and is commercially produced as an environmentally friendly mycoinsecticide. We sequenced the genome of B. bassiana and a phylogenomic analysis confirmed that ascomycete entomopathogenicity is polyphyletic, but also revealed convergent evolution to insect pathogenicity. We also found many species-specific virulence genes and gene family expansions and contractions that correlate with host ranges and pathogenic strategies. These include B. bassiana having many more bacterial-like toxins (suggesting an unsuspected potential for oral toxicity) and effector-type proteins. The genome also revealed that B. bassiana resembles the closely related Cordyceps militaris in being heterothallic, although its sexual stage is rarely observed. A high throughput RNA-seq transcriptomic analysis revealed that B. bassiana could sense and adapt to different environmental niches by activating well-defined gene sets. The information from this study will facilitate further development of B. bassiana as a cost-effective mycoinsecticide.

Abstract
The epoxide hydrolase (EH)-encoding gene (EPH1) from the basidiomycetous yeast Xanthophyllomyces dendrorhous was isolated. The genomic sequence has a 1,236-bp open reading frame which is interrupted by eight introns that encode a 411-amino-acid polypeptide with a calculated molecular mass of 46.2 kDa. The amino acid sequence is similar to that of microsomal EH and belongs to the alpha/beta hydrolase fold family. The EPH1 gene was not essential for growth of X. dendrorhous in rich medium under laboratory conditions. The Eph1-encoding cDNA was functionally expressed in Escherichia coli. A sixfold increase in specific activity was observed when we used resting cells rather than X. dendrorhous. The epoxides 1,2-epoxyhexane and 1-methylcyclohexene oxide were substrates for both native and recombinant Eph1. Isolation and characterization of the X. dendrorhous EH-encoding gene are essential steps in developing a yeast EH-based epoxide biotransformation system.

Abstract
Chiral intermediates constitute a significant part of the fine chemicals market, which is strongly influenced by trends in the pharmaceutical industries, where approximately 70% of pharmaceuticals are expected to be enantiomerically pure in the next century as compared to 25% today. The main technologies by which enantiomerically pure ingredients are obtained today are (dynamic) resolutions of racemic mixtures. Asymmetric syntheses are being developed, but their applications in industry are still under represented. Biotechnological methods, resolutions as well as asymmetric syntheses, are becoming increasingly important in the industrial production of fine chemicals.
