绿色木霉3711在稻壳基上产生纤维素酶条件的研究

通过对绿色木霉３７１１在稻壳粉培养基上培养产生纤维素酶活力的测定,得出绿色森酶１产生纤维素酶的适宜条件为：最适ＰＨ为４．５￣５．０,最适温度为３０℃,最佳培养时间是４ｄ。用４％ＮａＯＨ处理的稻壳粉做２基碳源较未经处理的稻壳粉做２基碳源产生纤维素酶ＣＭＣ糖化力高。     

内生细菌与木霉复合处理诱导甜瓜对枯萎病的抗性

在对甜瓜枯萎病温室防效试验的研究中发现，内生枯草芽孢杆菌B6菌株与绿色木霉T23菌株复合处理的相对防效达82．22％，比B6和T23的单独处理分别提高32．8％和146．7％。分析比较了B6和T23单独和复合处理甜瓜幼苗后，甜瓜根部防御反应相关酶系苯丙氨酸解氨酶、过氧化物酶、多酚氧化酶、β-1，3-葡聚糖酶比活性的变化趋势。结果表明：内生细菌B6和木霉T23复合接种，其苯丙氨酸解氨酶、过氧化物酶、多酚氧化酶和β-1，3-葡聚糖酶比活性比单独接种有不同程度的增强，这种变化在挑战接种甜瓜枯萎病菌之后更加明显。     

Phylogeny and biodiversity of Trichoderma and Hypocrea and its implications on taxonomy

Safe strain identification and species recognition is an important issue for Trichoderma and Hypocrea, because members of the genus are economically important producers of industrial enzymes and antibiotics, have application as biocontrol agents against plant pathogens, whereas some have become known as opportunistic pathogens of immunocompromised mammals and humans. However, classical approaches based on the use of morphological and phenetic characters have been difficult to apply, due to…     

绿色木霉生物学特性及防治的研究

通过对大田食用菌生产各个环节中绿色木霉的侵入途经、最适温度、湿度、酸碱度及防治方法的研究,证明绿色木霉存在于培养基内,灭菌不彻底就会大量发生,并由空气气流传播.绿色木霉25～30℃、相对湿度70%以上、pH 5.5～6环境生长最快.增强栽培菌种的抗病力、已污染菌袋日光曝晒3 d后喷0.2%克霉灵治愈率90%以上.
