苯并[a]芘降解菌Acinetobacter sp. Bap30菌株的分离、鉴定及降解特性研究

提出一种新的方法, 用于富集苯并[a]芘耐受菌株。该方法使用多孔介质脱脂棉作为载体, 从连续流动的流体--下水道污水中富集菌株。利用介质截留法、富集培养法等理论, 为富集目标微生物提供了最佳条件。以苯并[a]芘为唯一碳源和能源, 从下水道沉积物中分离、筛选出4株苯并[a]芘耐受菌株, 其中一株能在20天内将40 mg/L的苯并[a]芘降解28.7%。通过16S rRNA基因序列分析和部分生理生化特征分析, 鉴定该菌株为Acinetobacter sp. Bap30。这是不动杆菌可降解苯并[a]芘的首次报道。添加其他碳源和低分子量多环芳烃--菲作为共代谢底物, 研究菌株的共代谢作用。研究结果对石油污染的土壤或者焦化废水等工业污水中的高分子量多环芳烃--苯并[a]芘具有非常重要的实践意义。     

一种腹柱虫Gastrostyla sp.包囊形成过程中纤毛器的去分化

Ｇａｓｔｒｏｓｔｙｌａ ｓｐ．包囊形成过程中纤毛器的去分化存在着三种形式：１．）从细胞前端开始进行；２．）从细胞后端开始进行；３）从细胞两端朝中央进行。其中纤毛器的去分化与伪尖毛虫不同之处在于；Ｇ．ｓｐ．是口围带先瓦解，其次是口侧膜；口围带瓦解的顺序是从其前端向后进行，而伪尖毛早恰好都相反。Ｇａｓｔｒｏｔｙｌａ ｓｐ。成包囊过程中纤毛器的去分化和冠突伪尾柱虫相似之处在于：口围带瓦解的方向均是从其前

A new genus and species of bythitid fish (Teleostei: Ophidiiformes) from New Zealand

Brosmodorsalis persicinus n. gen., n. sp. is described from specimens collected from shallow coastal rocky reefs of northern New Zealand. Brosmodorsalis is placed in the bythitid fish subfamily Brosmophycinae because it has the caudal fin separate from the dorsal and anal fins. The genus differs from all others within the subfamily by the origin of the dorsal fin being well in advance of the posterior margin of the operculum and the anterior dorsal fin rays being free of membrane.     

存在于牡蛎肝胰腺的病毒样颗粒的发现

近年来，人工吊养牡蛎时有发病，从中采样进行电镜观察，发现一种直径为 １５０～１８０ｎｍ，有包膜，存在于细胞质中的球状病毒样颗粒，以及另一种大小为 ５０～８６ × ２１０～２８０ ｎｍ，有包膜，存在于细胞质中的弹状病毒样颗粒．该形态大小的球状病毒颗粒在长毛对虾和珠带拟蟹宋螺中也可见．     

Report on Crassispirinae Morrison, 1966 (Mollusca: Neogastropoda: Turridae) from the China Seas

The present paper reports 32 turrid species from the China Seas, belonging to eight genera of the subfamily Crassispirinae of the family Turridae. Four new species are described: Funa cretea sp. nov., Inquisitor plurivaricis sp. nov., Inquisitor vividus sp. nov. and Ptychobela resticula sp. nov. Eight species are recorded for the first time from the China Seas.
