本发明提供了一种下调或不表达单胺氧化酶的重组广谱绿僵菌, 或其中色胺含量高于野生型广谱绿僵菌,重组广谱绿僵菌是菌株本身,菌株后代,菌株产生的分生孢子,菌株产生的菌丝体或它们的任意组合。 从重组广谱绿僵菌中敲除单胺氧化酶基因,显著提高了绿僵菌中色胺的浓度, 从而显著提高其杀虫效率,使野生型广谱绿僵菌的半致死时间LT50从7.33±0.445天缩短到6.136±0.488天。 本发明的重组广谱绿僵菌对...
Purdue University innovation that creates a "fingerprint-like pattern" to identify foodborne pathogens without using reagents has been licensed by Hettich Lab Technology. The technology is...
Irrespective of the fact that chlamydial infections afflict more than 500 millions of people in the world, little is known about host defense mechanisms involved. Several chlamydial antigens are being...
Poly(β-hydroxyalkanoates), PHAs, are thermoplastic polyesters, which have potential for use as biodegradable plastics. The material properties of PHAs depend upon their chemical structure. Pseudomonas...
In the African Cape buffalo, circulating serum xanthine oxidoreductase (XOR) produces trypanotoxic levels of hydrogen peroxide (H2O 2). Previous, preliminary studies suggest that mammalian serum XOR H...
Dissimilatory Fe(III) reduction is one of the most significant metabolisms in sedimentary environments. Molecular and geochemical studies conducted on uranium contaminated sediments suggested that Fe(...
Genomic analysis and physiological experiments conducted on the lignocellulosic biomass degrading bacterium C. phytofermentans, indicates that it can degrade and utilize a wide-range of carbohydrates ...
The properties of a previously unknown enzyme, denominated cyclodextrin glycosyltransferase, produced from Bacillus lehensis, were evaluated using affinity chromatography for protein purification. Enz...
Nitrogen (N) dynamics within the hypolimnion of a thermally stratified reservoir were examined to test an in situ approach to measuring dinitrogen (N2) and nitrous oxide (N2O) production rates wherein...
We studied trophic dynamics in a warm eutrophic subtropical river (Bremer River, Australia) to determine potential sources of dissolved organic carbon (DOC) and the fate of heterotrophic bacterial pr...
In this work, the optimization of hydrogen production by photo-fermentation bacteria immobilized on agar gel granule was systematic investigated in batch culture. Experiment focus on the effect of som...
