Conteúdo: |
Corn is the cereal most produced in the world. Corn starches were modified by HCl 0.1 mol L-1 in alcoholic and aqueous solutions. Three mass losses can be observed in the degradation process using TG-DTG curve. The native and treated starches samples don't show differences in the stability region. With DSC curves were observed lower values of the ΔH of gelatinization of the modified starch by HCl in the alcoholic solutions. The modifications using alcoholic solutions demonstrated a good alternative to obtain modifies starches. |

Mineralisation of the fungicide 14C-labelled metalaxyl fungicide in Brazilian soils. |

Conteúdo: |
Laboratory incubation experiments were carried out to estimate the mineralisation of metalaxyl 14C {N-(2-6 dimethyphenyl)-N-(methoxyacetyl) alanine methyl ester} in four Brazilian soils with different physico-chemical properties, at 3 and 30 ?g a.i. g-1. In the Petrolina sandy soil the mineralisation presented higher 14CO2 production rates, at two essayed concentrations, after 70 days. Microbiological studies were done to determine the numbers of bacteria, actinobacteria and fungi (CFU g-1 soil). In relation with other microbial community, bacterial population demonstrated to be a major component of the cultivable heterotrophic community after the application.of the compound. No detectable metabolites were found in this study. The results suggest that soil properties and application history may have a strong influence on the fungicide behavior in these soil samples. |
