Outline of Final Research Achievements |
We previously reported that Bacillus cereus and its close relatives accumulate silicon (Si) in and around a spore coat layer. Si is taken up from the environment as soluble silicate (Si[OH]4), which is then polymerized and accumulated as insoluble silica (SiO2). The spore coat is a proteinaceous shell composed of more than 50 proteins. Silica accumulation in and around the spore coat strongly suggests that spore coat proteins play an important role in silica formation. In this study, we found that one of the spore coat proteins, CotB1, mediates the accumulation of silica.
