Dosimetria esporular: Bacillus subtilis TKJ6312 como biossensor de radiação solar biologicamente ativa
2009
Since 2000, spore dosimetry and spectral photometry have been performed in parallel at the Southern Space Observatory, Sao Martinho da Serra (Southern Brazil). A comparative study involving data from Punta Arenas - Chile (53.2o S), Sao Martinho da Serra (29.5o S), Padang - Indonesia (0.9oS), Brussels - Belgium (50.9o N) and Kiyotake - Japan (31.9o N) from 2000 to 2006 is presented. The Spore Inactivation Doses presented the higher values in summer (973 ± 73 for Punta Arenas and 4,369 ± 202 for Sao Martinho da Serra, as well 1,402 ± 170 and 3,400 ± 1,674 for Brussels and Kiyotake, respectively). The simplicity, robustness and high resistance of bacterial spores makes the biosensor an potential biological tool for UV-B monitoring.
