摘要
WHS3(Serratia marcescens)菌是一株几丁质酶的高产菌株,在诱导培养基中几丁质酶的产量可达 84.4 g/mL。通过对中国棉铃虫进行的生物测定表明:WHS3菌所产的几丁质酶(A3)能有效地提高HaSNPV的毒 力20% ~70% ,LTs0、LT90比对照组缩短天数最高可达1.1d、1.3d。

Abstract
WHs3 Serratia marcesscens is a high yield bacterium of Chitinase.The yield of chtinase in induce medium was 84.4t~g/mI .The chitinase(A3) can enhance the toxicity of Helicoverpa arm igera nucleopolyhedrovirus(HaSNPV)up tO 20% ~70% .The LT50 and LT90 were shortened 1.1 and 1.3 days respectively com paring with contro1
