项目摘要
Aerobic heterotrophic bacteria containing bacteriochlorophyll a were isolated from specimens from a wide variety of marine environments on the coast of Australia (on the west cost, Shark Bay, Lake Clifton, Lake Heyward and Perth ; on the east coast, near Townsville and Brisbane ; on the north coast, near Darwin ; on the south coast, near Adelaide and Tasmania Island).The bacteria were found in a high proportion (10 to 30%) of the total hetero-trophic bacterial strains isolated from marine algae, seagrasses, stromatolites, the epiphites on stromatolites, and from seawater and sands ; in some cases they constituted up to 49% of the total. This is much higher than the previous report of 6% from Japan. A high percentage, 13%, was also found in the seawater of Hamelin Pool, at Shark Bay, where the salinity was 66%. The proportion of these bacteria was generally low in seawater and sands, with a few exceptions. There were no bacteriochlorophyll-containing bacteria on sponges or corals. Finally about 300 strains were found to contain bacteriochlorophyll a.The isolated strains were orange or pink, and most had absorption maxima around 800 and 850 to 870 nm, the absorption of bacteriochlorophyll in vivo.The maximum bacteriochlorophyll content was 1 nmol/mg dry wt. of bacterial cells. Most of the bacteria did not grow photoheterotrophically under anaeroーbic conditions in a broth medium containing succinate.Cells and cell extracts grown under aerobic conditions had photochemical activities such as reversible photooxidations of the reaction center and cytochrome(s). Some strains showed denitrifying activity. The optimal salinity for bacterial growth varied between strains.
从澳大利亚海岸各种海洋环境的标本中分离出含细菌叶绿素a的好氧异养细菌(西海岸有鲨鱼湾、克利夫顿湖、海沃德湖和珀斯;东海岸靠近汤斯维尔和布里斯班;北海岸靠近达尔文;在南海岸,靠近阿德莱德和塔斯马尼亚岛)。(10 - 30%)的总异养细菌菌株分离自海藻、海草、叠层石、叠层石上的附生物以及海水和沙子;在某些情况下,他们占总数的49%。这比日本此前报告的6%要高得多。此外,在含盐量为66%的筲箕湾海梅林池海水中,亦发现有高达13%的海水含盐量。这些细菌在海水和沙子中的比例一般很低,只有少数例外。海绵或珊瑚上没有含细菌叶绿素的细菌。结果表明,约有300株菌株含有细菌叶绿素a,分离菌株呈橙子或粉红色,大多数在800和850 ~ 870 nm处有最大吸收,最大细菌叶绿素含量为1 nmol/mg干重。细菌细胞。大多数细菌在厌氧条件下不能在含琥珀酸的肉汤培养基中进行光异养生长,而在好氧条件下生长的细菌细胞和细胞提取物具有光化学活性,如反应中心和细胞色素的可逆光氧化。部分菌株表现出明显的絮凝活性。细菌生长的最适盐度因菌株而异。
