Abstract

Microbial degradation of pollutants is a safe and cost-effective way to clean the environment. However, little is known on changes at the cell ultrastructure level and on the mechanisms of adaptation in general to xenobiotics under conditions of their biodegradation. Rhodococcus sp. strain 7Ba is capable of preserving long-term viability and the ability to degrade when growing with phenol at up to 1 g/L. Destructive morphological changes at the ultrastructural level were not detected in the cells growing on phenol, which indicated rapid adaptation to it. Strain 7Ba cells formed a polysaccharide matrix under all experimental conditions. Investigation of the growth of spore-forming bacteria cells on glyphosate (0.5 g/L) showed that, although the substrate was not optimal, the cells were able to grow on it. The cells of Paenibacillus sp. GP5-2 and Rossellomorea sp. GP5-7 exhibited ultrastructural changes and a delay in spore formation (for strain GP5-2). The detected changes were adaptive, and further study will improve our understanding of their strategy ensuring the preservation of survival and the ability to degrade.

存在污染物时生长的细菌细胞的活力和超微结构变化
摘要 微生物降解污染物是清洁环境的一种安全且具有成本效益的方法。然而,人们对细胞超微结构水平的变化以及在生物降解条件下对异种生物的一般适应机制知之甚少。Rhodococcus sp. 菌株 7Ba 能够在苯酚浓度高达 1 克/升的条件下保持长期活力和降解能力。在苯酚上生长的细胞未发现超微结构层面的破坏性形态变化,这表明它们能迅速适应苯酚。菌株 7Ba 的细胞在所有实验条件下都能形成多糖基质。对孢子形成菌细胞在草甘膦(0.5 克/升)上生长情况的调查表明,虽然该基质不是最佳的,但细胞仍能在其上生长。Paenibacillus sp. GP5-2 和 Rossellomorea sp. GP5-7 的细胞表现出超微结构变化和孢子形成延迟(对于菌株 GP5-2)。检测到的变化是适应性的,进一步的研究将使我们更好地了解它们的策略,以确保生存和降解能力。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
