本文总结了30年来作者在应用微生物学研究中所取得的一系列进展和成就如下: 麦角菌:麦角菌能引起多种禾谷类作物的严重病害,但它能产生有药用价值的一系列麦角碱,其中麦角新碱已被广泛地应用于妇产科临床,防治妇女产后大出血。麦角的含碱量随寄主而不同,一般为0.061%~0.34%.麦角菌的栽培已在黑麦上获得成功,由拂子茅(Calamagrostis epigious)分离的菌株Claviceps purpurea,Ce-3系列栽培产生的麦角的含总碱量达0.22%~0.40%.麦角碱的人工发酵生产已于1963年突破。利用灭菌的小麦粒接种麦角菌后,培养25天后,麦角碱的含量可达0.06%,与从黑麦地里采集的野生麦角的含碱量相近。在培养基内单独或混合加入葡萄糖、蔗糖、蛋白胨、硝酸铵和磷酸二氢钾可大大提高麦角碱产量。这种生产方法非常适用于条件有限的农村小工厂。麦角碱的液体深层发酵生产亦已取得成功,总碱和新碱的产量分别达到0.00936%和0.00579%.用鱼粉代替谷氨酸作氮源,总碱和新碱的产量分别增至0.0304%和0.0178%(发酵滤液)及0.160%和0.049 5%(菌丝体)。应用产碱期菌丝(idiophase m...

One of the outstanding advantages of using Lagenidium giganteum as a mosquito biocontrol agent is that it can recycle and persist in mosquito breeding sites. This recycling is completed through its host passage and, probably, its sapro-phytic development in the environment. The former has been documented in a wide range of research, but the latter infered only in a few papers. Since the saprophyti-sm of L. giganteum might contribute directly to its efficiency in mosquito control, it's of great significance to...

One of the outstanding advantages of using Lagenidium giganteum as a mosquito biocontrol agent is that it can recycle and persist in mosquito breeding sites. This recycling is completed through its host passage and, probably, its sapro-phytic development in the environment. The former has been documented in a wide range of research, but the latter infered only in a few papers. Since the saprophyti-sm of L. giganteum might contribute directly to its efficiency in mosquito control, it's of great significance to confirm if this phenomenon occurs and to evaluate it quantitatively, if possible.

1991年1—4月,作者在实验室中观察了水中分别加入肝粉、葵花籽粉、田泥、淤泥、丝藻和人造沙后,对致倦库蚊幼虫的大链壶菌(Lagenidium giganteum)感染率的影响。发现除人造沙外,其他几种物质皆能明显地增加蚊虫的大链壶菌感染率。并且在一定范围内,蚊虫感染率与所加物质的量成正相关关系。据估计,每100ml水中加入6.4mg葵花籽粉或6mg肝粉分别可使蚊虫感染率增加2倍和3倍。作者认为大链壶菌在肝粉和葵花籽粉中弥漫地腐生生长,并释放大量额外的游动孢子,是这两种有机物增加蚊虫感染率的主要原因。 对田泥、淤泥和人造沙的研究表明,土壤肥力与蚊虫感染率的增加有关。丝藻则可能是由于净化水质造成有利于大链壶菌游动孢子活动的环境而增加蚊虫的感染率。
