摘要

有毒水华形成蓝藻,铜绿微囊藻,已在世界范围内频繁报道。这些菌落形成有毒的蓝藻窝藏了广泛的异养细菌群落。本研究试图了解铜绿假单胞菌的生长动态,并从印度南部的两个淡水池塘中分离出与菌落相关的可培养异养细菌。对这些研究区进行的月度监测显示,高营养含量的温暖停滞水体有利于铜绿假单胞菌华的形成。工位1的温度、硝酸盐和磷酸盐峰值分别达到30.5°C、4.48 mg/L和1.64 mg/L,工位2的温度、3.45 mg/L和0.62 mg/L。分离得到28株细菌,分别属于α变形菌门、β变形菌门、γ变形菌门、放线菌门和厚壁菌门。在这28株菌株中,厚壁菌门菌和铜绿假单胞菌在两个研究区域均占优势。

Phylogenic diversity of bacteria associated with potentially toxic cyanobacteria Microcystis aeruginosa: a synthesis on its bloom dynamics.

The occurrence of toxic bloom-forming cyanobacteria, Microcystis aeruginosa, has been frequently reported worldwide. These colony forming toxic cyanobacteria harbour a wide range of heterotrophic bacterial communities. The present study has attempted to understand the bloom dynamics of M. aeruginosa along with isolating their colony-associated culturable heterotrophic bacteria from two freshwater ponds in south India with a persisting cyanobacterial bloom. The monthly monitoring of these study areas revealed the conducive role of warm, stagnant waters with high nutrients in forming M. aeruginosa bloom. The peak values of temperature, nitrate, and phosphate at station 1 reached up to 30.5 °C, 4.48 mg/L, 1.64 mg/L, and at station 2, 31 °C, 3.45 mg/L, and 0.62 mg/L, respectively. Twenty-eight bacterial isolates belonging to Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Actinobacteria, and Firmicutes were obtained during the study. Among these 28 isolates, Firmicutes was dominant with the M. aeruginosa bloom from both the study areas.

期刊介绍: Unlike journals which specialize ever more narrowly, Folia Microbiologica (FM) takes an open approach that spans general, soil, medical and industrial microbiology, plus some branches of immunology. This English-language journal publishes original papers, reviews and mini-reviews, short communications and book reviews. The coverage includes cutting-edge methods and promising new topics, as well as studies using established methods that exhibit promise in practical applications such as medicine, animal husbandry and more. The coverage of FM is expanding beyond Central and Eastern Europe, with a growing proportion of its contents contributed by international authors.
