Haricot beans are the most important food and cash crop for most of the Ethiopian farmers. However, bean stem maggot (BSM) (Ophiomyia species) is limiting the production of the crop particularly in dry areas. Three species are involved in the infestation: Ophiomyia phaseoli, Ophiomyia spencerlla and Ophiomyia centrosematis. Two decades ago, two management options of BSM were developed and used for the last twenty years.... Read more.

A lectin was purified from the tuber, Dioscorea mangenotiana in this study. The lectin agglutinated erythrocytes from human and rabbit, and the activity was inhibited by glucose and N-acetyl-D-glucosamine with minimum inhibitory concentration (MIC) of 50 and 25 mM, respectively. The lectin was composed of two isoforms, DML I and DML II. The apparent native molecular mass of DML I was estimated at 51 kDa and the... Read more.

Alcohol production in industry is carried out almost exclusively by means of batch or continuous fermentation processes. In both cases, cells are found spread throughout the fermenting substrate and have to go through a centrifugation cycle in order to be recovered. Investment in equipment is very high and performance is often lower than expected. According to available information, ethanol fermentation performance... Read more.
