Effect of processing conditions on cyanide content and colour of cassava flours from West Africa

  The evolution of cyanide content and colour were monitored during the processing of lafu, traditional flour and improved flour from five cassava cultivars from Benin. In addition, the total phenol, polyphe-noloxidase (PPO), peroxydase (POD) and linamarase activities were assessed. The processing of cassava in lafu and improved flour proved superior for producing safe and white non-fermented and fermented...

The influence of cultural and physical conditions on the antimicrobial activity of bacteriocin produced by a newly isolated Bacillus megaterium 22 strain

  Bacillus megaterium 22, a soil isolate, produced a bacteriocin that exhibited a broad range of inhibitory activity against food-spoilage microorganisms includingSalmonella typhimurium and Staphylococcus aureus. The antimicrobial activity peaked at the early stationary phase. De Man Rogosa Shrarpe (MRS) was the best medium for bacteriocin production, where growth of B....
