Starch, a carbohydrate used as a reserve of energy in most plants, is widely used in the food industry, either as a main component or as a thickener. Considering the application of this as an ingredient in the food industry, the study of the morphological and thermal properties of this food is of great importance because it can predict its behavior during and after the processing of this. Methodologies such as scanning electron microscopy, light scattering and optical microscopy are the most used tools in the morphological characterization of the starch granule generating accurate results and good quality. Regarding the methodologies for the study of thermal properties, the rapid amylographic analyzer and the differential scanning calorimetry are the most used. The set of results obtained with these methodologies, allows to know the technological properties of the starch, characterizing them, and even to identify the origin of this one. |

Abstract: Brazilian strains of Bacillus thuringiensis, namely S701, S764 and S1265 were analysed regarding their cry gene and protein contents, crystal type, and activity against larvae of the lepidopteran fall armyworm (Spodoptera frugiperda Smith), the velvet caterpillar (Anticarsia gemmatalis), the dipterans (Culex quinquefasciatus and Aedes aegypti) and the coleopteran (Tenebrio molitor). The LC50 of the strains against second instar larvae of S. frugiperda or A. gemmatalis revealed a high potency against those insect species. The spore?crystal mixtures of the isolates were analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and showed similar protein pattern as the B. thuringiensis subsp. kurstaki strain HD-1 (proteins approximately 130 and 65 kDa) for isolates S701 and S764, respectively, and only one major protein of approximately 130 kDa for isolate S1265. The polymerase chain reaction (PCR) using total DNA of the isolates and general and speci?c primers showed the presence of cry1Aa, cry1Ac, cry1Ia and cry2Ab genes in the two isolates serotyped as B. thuringiensis kurstaki (S701 and S764) and the presence of cry1D and cry2Ad in B. thuringiensis morrisoni S1265 strain. Scanning electron microscopy of strains S701 and S764, showed the presence of bipyramidal, cuboidal and round crystals, like in strain HD-1 and bipyramidal and round crystals like in strain S1265. |
