Abstract
A novel, aerobic, Gram-positive actinomycete strain, designated XMU15(T), was isolated from an ocean sediment collected from Zhaoan Bay in the East China Sea and was subjected to a polyphasic approach to determine its taxonomic position. The isolate grew optimally at 28 C and at pH 7.0 in the presence of 3% (w/v) NaCl on ISP medium 2. Gelatin liquefaction, milk coagulation and nitrate reduction were positive. Cellulose and starch hydrolysis, hydrogen sulfide and melanin production, and catalase, urease and oxidase activities were negative. The predominant menaquinone of the isolate was MK-9 (H-4), and meso-diaminopimelic acid was the diagnostic amino acid in the cell wall. The phospholipids of the isolate comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, and a minor amount of phosphatidylethanolamine. The major fatty acids of the strain were iso-C-16:0 (26.36%), C-17:(1)omega 6C (16.80%), C-15:0 (16.2 %), C-16:0 (8.90 %), C-17:1 omega 8C (7.69%) and iso-C-16,1 H (5.95%). The DNA G+C content of the genomic DNA was 68.1 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that the isolate fell within the evolutionary radiation encompassed by the genus Saccharomonospora and showed the highest 16S rRNA gene sequence similarity (96.7%) to Saccharomonospora xinjiangensis DSM 44391T. Based on the results of 16S rRNA gene sequence analysis and phenotypic and genotypic characterization, strain XMU15(T) (=KCTC 19701(T) =CCTCC AA 209048(T)) represents a novel species of the genus Saccharomonospora, for which the name Saccharomonospora marina sp. nov. is proposed.

  • 滇缅铁路筹建史:中国构建西南出海口的历史变迁 

    尚萌 (2015-12-23)
    中国是一个海陆兼备的国家。近代以来,中国人寻求西南出海口的步伐从未停止过,修建滇缅铁路就是这种不懈努力和尝试的突出代表。在历代国人提出的各种修建滇缅铁路的构想和方案背后,其所代表的追求和努力方向都是一致的,即克服中国西南内陆地区交通落后、远离东部海港的弊端,利用毗邻印度洋沿岸国家缅甸的地缘优势,建构最便捷的通向海外的交通线,规避主要依赖太平洋水路的单一性,实现“两洋”战略。 十九世纪中期,英国连接云南与缅甸的铁路计划开启了滇缅铁路修筑的 ...
  • 由蒙自等海关看云南对外贸易的第一个高潮(1889-1910) 

    曾婷 (2012-10-17)
    云南省自1889年开埠以后,其对外贸易迅速发展。洋货的大量涌入促进传统经济结构的松动,小农经济开始瓦解,商品流通范围扩大,商业资本也有了一定程度的积累,开始出现新兴的商业组织。云南省逐渐整合成一个统一的区域市场,通过香港的转口贸易,加强与国内东部沿海地区以及国外的经济联系,逐步被纳入世界市场体系。 绪论,说明选题缘起及所用资料,回顾相关学术史研究,阐述笔者的写作思路。 第一章,介绍云南省开埠以前的对外贸易状况,如传统的对外贸易路线以及贸 ...
  • 云贵区域市场研究(1889-1945) 

    肖良武 (2007-06-29)
    区域市场是全国统一市场的有机组成部分。我国在“十一五”规划中,将区域规划的编制放在重要位置。以大区域进行统一规划的构想,已经成为中国经济发展的重要思路。处于经济现代化时期的今天,研究区域市场问题可以说是一项具有重大理论意义的课题。本文将云贵作为一个区域来研究,既符合我国区域规划发展的要求,也符合打破省级行政区划、进行跨省区统一规划的战略构想。本文主要运用历史学、经济学、地理学及数学等相关学科的理论,探讨近代云贵区域市场随着区域开放,市场 ...
