Bioactive compounds from Hagenia abyssinica with activity against bean pathogenic bacteria

Common bean (Phaseolus vulgaris L.) is a major food crop in Africa and its production is plagued by diseases that reduce the potential yield, thus threatening food security. This study evaluated compounds from Hagenia abyssinica for bioactivity against bean bacterial pathogens Xanthomonus axonopodis pv. phaseoli and Pseudomonus savastanoi pv. phaseolicola. One triterpenoid, 1,3,19-trihydroxy-2-oxo-12-ursen-28-oic acid...

Harnessing the bio-stimulatory properties of heavy metals in improving biogas yield from agro-wastes: Two-phase logistic modeling of diauxic response

This study aimed to harness the bio-stimulatory properties of two heavy metals, Zn (II) and Cd (II) at low concentrations in improving biogas yield from anaerobic digestion of cow dung (CD) and pig dung (PD). Proximate characteristics of the feedstocks were estimated by adopting standard methods. The batch fermentation experiment which was set-up in triplicates with equal weights of CD/PD and three concentrations: 0.02,...
