【摘要】 在长期贮存水中细菌所处营养环境逐渐由丰富转为匮乏,为适应这种环境变化,水中细菌会采取一系列自组织行为来应对低营养环境,并形成以下特性:(1)降低代谢水平、减缓繁殖速度;(2)扩大对各种基质的利用能力;(3)缩小体积、增加比表面积;(4)多以生物膜形式存在;(5)抗性增强。在解决贮存水的水质恶化问题时应充分注意水中细菌的这些特性,以确保长期贮存水的水质安全。更多还原

【Abstract】 The nutrition for the bacteria in the standing storage water changes gradually from plentiful to deficiency. The bacteria adopt a series of self-organization to adapt the sub-nutrition environment with forming the following characteristics: 1) Decreasing the metabolic level, slowing down the breeding velocity; 2) Enlarging the utilization ability for different kind of material; 3) Reducing the bulk and increasing the specific area; 4) Presenting in the form of bio-film, 5) Strengthening the resistance. To ensure the water quality security of long-term storage water, these characteristics should be paid attention to when solving the issue of water quality deterioration for the storage water.更多还原
