Compounds of polyketide origin possess a wealth of pharmacological effects, including antibacterial, antifungal, antiparasitic, anticancer and immunosuppressive activities. Many of these compounds and their semisynthetic derivatives are used today in the clinic. Most of the gene clusters encoding commercially important drugs have also been cloned and sequenced and their biosynthetic mechanisms studied in great detail. The area of biosynthetic engineering of the enzymes involved in polyketide biosynthesis has recently advanced and been transferred into the industrial arena. In this work, we introduce a computational system to provide the user with a wealth of information that can be utilized for biosynthetic engineering of enzymes involved in post-PKS tailoring steps. Post-PKS tailoring steps are necessary to add functional groups essential for the biological activity and are therefore important in polyketide biosynthesis.

White and brown strains of Flammulina velutipes were inter-crossed. All F1 showed light-brown fruitbody, suggesting that a gene for the brown fruitbody was incompletely dominant against the white one. And backcross experiment showed that more than two genes were involved in color determination. To isolate a molecular marker linked to fruitbody color, a set of primers was designed from a sequence of clones derived by a bulked segregant analysis. These markers showed a specific band which co-segregated with brown fruitbody forming strains.

The microbial diversity in soil ecosystems is higher than in any other microbial ecosystem. The majority of soil microorganisms has not been characterized, because the dominant members have not been readily culturable on standard cultivation media; therefore, the soil ecosystem is a great reservoir for the discovery of novel microbial enzymes and bioactivities. The soil metagenome, the collective microbial genome, could be cloned and sequenced directly from soils to search for novel microbial resources. This review summarizes the microbial diversity in soils and the efforts to search for microbial resources from the soil metagenome, with more emphasis on the potential of bioprospecting metagenomics and recent discoveries.

This study is aimed to evaluate skin whitening effects of Sanguisorba officinalis and Stichopus japonicus for cosmeceutical ingredients. The extract of Stichopus japonicus showed 61.78% inhibition of tyrosinase activity, and the mixture of Sanguisorba officinalis extract and Stichopus japonicus extract showed 59.14% inhibition of tyrosinase activity. On the clone M-3 cell meloanocyte, the mixture of Sanguisorba officinalis extract and Stichopus japonicus extract showed remarkable inhibition of melanogenesis. Also, those extracts were not irritable in ocular irritation test. It is concluded from these results that Sanguisorba officinalis and Stichopus japonicus have skin whitening effect. It could be used as natural depigmental material in cosmeceutical ingredients.
