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.

The study relied on secondary data accessed from World Bank data base spanning over 37 years (1976-2012). Data obtained were analyzed using canonical cointegration regression (CCR) method. It was found that poor education (secondary school enrollment) was exerting negative influence on innovation levels in SSA (p<0.05) in the long-run. Credit to the private sector as well as value of official aids received, labour... Read more.
