| 摘要 |
The present invention is based on a Bacillus the spores and vegetative cells forms of which are a different colour because of differential presence of at least one carotenoid in the spore and vegetative cell forms of the Bacillus. The Bacillus may therefore be used in detection methods and biosensors. The Bacillus may also be used a colourant and a dye and in the generation of foods, food supplements, probiotic compositions, dyes, cosmetic, pharmaceuticals and vaccines. The Bacillus may also be used for the production of carotenoids, precursors thereof and downstream derivatives. |
