The properties of extracellular cellulase obtained from Bacillus species (FIIRO Strain B223) on supplying cellulose from Brewers Spent Grain (BSG) were studied. Generally, a crude cellulase activity between 11,757 Units to 13,930 Units was observed for both sources of carbon (BSG and crystalline cellulose). The optimum pH and temperature of 5.0, and 30°C - 40°C for both sources of carbon was observed. Heavy metals such as copper, zinc, and iron inhibited the activities of B223 cellulase while the cellulase activities on alkaline earth metal (manganese) were moderate. The co-factor behaviour of manganese ion was also established. Local production of cellulase in Nigeria using local raw materials such as Brewers Spent Grain reduces enzyme cost;cost of finished products and increases gross domestic products. 展开更多

Protein baitsprays were produced from many different sources for the controlling fruit flies in the integrated pest management program around the world.Here,fruit fly baits were formulated based on cost-effective bait mixtures such as local jaggery,brewers spent grain(BSG),apple cider vinegar,wheat bran powder and local red wine with the fresh enzyme from papaya and pineapple.Fruit fly Baits were prepared by mixing the small amount of local detergent as insecticide.Our results indicated that the best efficient fruit fly bait for area wide integrated pest management(AW-IPM)is the BSG-based bait whereas the second efficient bait is local red wine-based bait.The highest fruit fly per trap per day(FTD)value by BSG-based bait traps was discovered.The highest female captured percentage is BSG-based bait with papaya solution.The field analysis of one week and one month old protein-based bait showed that FTD values decreased slightly while only one month old wheat bran-based bait dropped to the base.The BSG-based baits analysis is effective not only female fruit flies but also cockroaches male in Myanmar’s tropical region.Thus our results reveal that the efficient protein-based bait is the fresh BSG-based bait with papaya solution. 展开更多
