This study could have implications both for understanding the role of endospore-forming bacteria in the environment as well as in terms of improving the bioremediation processes. An endospore is a reduced form of a bacterium. These endospore-forming bacteria belong to the Bacillus and Clostridium genus. A special emphasis was given to endospore-forming bacteria, which could use sporulation as a survival strategy to resist in highly contaminated areas. Sporulating bacteria are derived from the Firmicute phylum and mainly consist of Gram positive bacteria. 3 Endospores enable bacteria to lie dormant for extended periods, even centuries. In endospore formation, the bacterium divides within its cell wall, and one side then engulfs the other. The main objective of this project is to investigate how these elevated concentrations of heavy metals affect both abundance and diversity of prokaryotes in the sediments. Endospore formation is usually triggered by a lack of nutrients, and usually occurs in gram-positive bacteria. Even if this water is properly treated with modern technologies, we can observe an accumulation of micro pollutants into the sediments, and particularly heavy-metals. Aerobic endospore-forming bacteria are taxonomically and physiologically diverse, and are ubiquitous members of soil microbial communities. Prior to 1980, the year of the compilation of the Approved Lists of Bacterial Names, four genera of aerobic endospore-forming bacteria had been established, with the genus Bacillus. By forming spores, bacteria can survive in hostile conditions. ABSTRACT The conspicuous morphological feature of endospore formation has lent itself from early on as an easily recognized property for taxonomic differentiation. Treated wastewater and runoff-water is released by the outlet of the sewage treatment plant of Vidy (Lausanne) directly into the Lake of Geneva via a pipe located 300m from the shore. Aerobic endospore forming bacteria may be considered to be potentially useful indicators of climate and/or environmental changes. Endospores are formed by a few genera of bacteria, such as Bacillus.

During endospore formation, these bacteria enter a. Endospores can survive without nutrients. Endospore formation is a survival strategy found among some bacteria from the phylum Firmicutes. The endospore consists of the bacterium's DNA and part of its cytoplasm, surrounded by a very tough outer coating.
