13. Calcário, nitrogênio e enxofre para a recuperação do capim-braquiária cultivado em solo proveniente de uma pastagem degradada. / Lime, nitrogen and sulfur for signal grass recovery in a soil from a degraded pasture.
O presente trabalho foi desenvolvido com o objetivo de avaliar as respostas da Brachiaria decumbens Stapf, cultivada em solo proveniente de uma pastagem degradada. O experimento foi desenvolvido em casa-de-vegetação do Departamento de Ciências Biológicas da Escola Superior de Agricultura "Luiz de Queiroz"/USP. O solo utilizado foi classificado como Neoss

14. Microbially Mediated Leaching of Low-Sulfur Coal in Experimental Coal Columns †
The leaching of a low-sulfur bituminous coal was investigated with experimental coal columns subjected to simulated rainfall events. Leachates from the columns became dominated by iron-oxidizing bacteria as evidenced by specific enrichment cultures and measurements of CO2 assimilation. Heterotrophic microorganisms were also present in the coal leachates, but

15. Accelerated Biodegradation of Cement by Sulfur-Oxidizing Bacteria as a Bioassay for Evaluating Immobilization of Low-Level Radioactive Waste
Disposal of low-level radioactive waste by immobilization in cement is being evaluated worldwide. The stability of cement in the environment may be impaired by sulfur-oxidizing bacteria that corrode the cement by producing sulfuric acid. Since this process is so slow that it is not possible to perform studies of the degradation kinetics and to test cement mi
