Alginate microporous beads promote higher ethanol productivity than the normal beads in a repeated-batch ethanolic process involving Saccharomyces cerevisiae LC 269108

Mass transfers pose significant challenge in fermentation due to wide diffusion gradient existing between the culture broth and the immobilized cells. In the present study, Saccharomyces cerevisiae LC 269108 was immobilized in a recently described microporous alginate beads. The new method was compared with the conventional calcium alginate gel beads in a repeated batch process for the production of ethanol. The...

Quantitative trait loci (QTL) mapping for intermittent drought tolerance in BRB 191 Ă— SEQ 1027 Andean Intra-gene cross recombinant inbred line population of common bean (Phaseolus vulgaris L.).

Drought is a major constraint of common bean (Phaseolus vulgaris L.) production in Uganda where irrigation for the crop is very uncommon. This study aimed to identify quantitative trait loci (QTLs) underlying drought tolerance in 128 F5 RILs derived from an Andean intra-gene cross between drought-tolerant SEQ 1027 and BRB 191. Eighteen traits were evaluated under drought stress and non-stress conditions in the field for...

Chemical study of Peganum harmala seeds

Peganum harmala belongs to the family Zygophyllaceae and is popularly known as "Arruda of Syria". It presents a broad therapeutic potential, highlighting the anti inflammatory, anticancer, analgesic, antiseptic and antibacterial activities. It is used in the preparation of religious rituals beverages with effects on the central nervous system as an inhibitor of the enzyme monoaminoxidase, whose action is due...
