Selenium protective activity against aflatoxin B1 adverse affects on Drosophila melanogaster

O objetivo deste trabalho foi investigar os efeitos da AFB1 e AFB1 + Se 4 em vários estágios de desenvolvimento da Drosophila melanogaster. Ambos diferentes concentrações da ABF1 e Se4+ aplicado com AFB1 foram alimentados durante a fase de desenvolvimento da mosca (ovo, larva e pulpa). Quando a progenese F1 do controle e aplicações foram comparadas com outros grupos, ABF1 ampliou o processo de metamórfose e na redução do número total de ovos. Porém esses efeitos negativos foram inibidos com o tratamento com selênio em diferentes concentrações (4.0 e 8.0 ppm). Esses resultados sugerem que o selênio pode efetivamente inibir AFB1 que induz anomalias nos estágios do desenvolvimento da Drosophila melanogaster.

Effect of single cell protein as a protein source in Drosophila culture

The effects of biomass of Phanerochaete chrysosporium at various concentrations (1; 2.5; 5; 10; 25; 50; 75 and 100 percent) on the growth of Drosophila melanogaster have been investigated. Biomass was used as a protein source instead of corn flour in Standard Drosophila Medium (SDM). It was seen that it causes increments in both body size of larvae and the numbers of offsprings, specially at higher concentrations (50, 75 and 100 percent) at the application of 100 percent concentration, metamorphosis accelerated and was completed one day before the control. There were phenotypic abnormalities in both control (0.64 percent) and applications with low concentrations (0.02-0.19 percent), while they were not observed at the application of 100 percent concentration.
