Genes encoding for glycosyl hydrolases （GH） in multiple families were recovered from an expression sequence tag library of Coptotermesformosanus, a xylophagous lower termite species. Functional analyses of these genes not only shed light on the mechanisms the insect employs to successfully use cellulosic materials as energy sources, which may serve as strategic targets for designing molecular-based bio-pesticides, but also enrich discoveries of new cellulolytic enzymes for conversion ofbiomass into biofuel. Our study demonstrated that cellulose could be converted to glucose by two recombinant endogenous glycosyl hydrolases （endo-β- 1,4 glucanase in GH9 and β-glucosidase in GH1）. While the former cleaved cellulose to cellobiose and cellotriose, the resulting simple cellodextrins were digested to glucose. Both of the Escherichia coli-expressed recombinant proteins showed properties that could be incorporated in a glucose-based ethanol production program.

黄曲霉是花生在生长和储存过程中存在的一种主要真菌。影响人类和动物的健康,对农业、商业都产生重大的影响,因为黄曲霉会产生毒性极强的天然毒素-黄曲霉毒素,它可以致癌、致突变、免疫抑制、致畸形等。从海洋中分离出的巨大芽孢可抑制黄曲霉毒素的生成,利用基因芯片分析的方法可以看出黄曲霉基因表达受到影响。结果表明,在实验组Jinhua 1012和UF715133-1的黄曲霉毒素B1浓度,超过85%的黄曲霉毒素B1被抑制,但仍超过在食品和饲料中的最大允许存在量。还有一些编码蛋白酶的基因显著下调,如短链脱氢酶、三价铁螯合物还原酶、二氢黄酮醇-4-还原酶等,这些基因在黄曲霉毒素生物合成中的作用并未阐明,其作用机制还有待进一步深入研究。

Silk damping is well known in the study of cosmic microwave background（CMB） and accounts for suppression of the angular power spectrum of CMB on large angular multipoles. In this article, we study the effect of Silk damping on the scalar-induced gravitational waves（SIGWs）. Resulting from the dissipation of cosmic fluid, the Silk damping notably suppresses the energydensity spectrum of SIGWs on scales comparable to a diffusion scale at the decoupling time of weakly-interacting particles. The effect offers a novel observable for probing the underlying particle interaction, especially for those mediated by heavy gauge bosons beyond the standard model of particles. We anticipate that pulsar timing arrays are sensitive to gauge bosons with mass ～10～3-10～4 GeV, while space-and ground-based interferometers to those with mass ～10～7-1012GeV, leading to essential complements to on-going and future experiments of high-energy physics.
