    The Effect of the Interaction of Varying Chicken Manure Supplement Levels with Three Different Solid Sisal Wastes Substrates on Sporocarp Cap Lengths and Diameters, Stipe Lengths and Diameters and Dry Weights of Coprinus Cinereus (Schaeff) S. Gray S.Lat
    (2013) Mwita, Liberata N.; Lyantagaye, Sylvester L.; Mshandete, Anthony M.
    Coprinus cinereus (Schaeff) S. Gray s.lat is an indigenous Tanzanian edible and medicinal mushroom, which grows in the wild on decomposed sisal wastes heaps. In the laboratory, it was cultivated on three types of sisal wastes substrates each supplemented with varying chicken manure concentrations 0, 5, 10, 15, 20 and 25% using solid-state fermentation bioreactors. The results showed that the interaction of sisal dust, sisal fibres and sisal decortications leaves wastes substrates with chicken manure at varying concentrations, produced a highly significant effect (p < 0.05) on cap lengths and diameters, stipe lengths and diameters and dry weights of C. cinereus (Schaeff) S. Gray s.lat. The interactions of sisal dust waste with 5% chicken manure concentration induced longest mean cap length and widest mean cap diameter. On the other hand, the interaction of sisal leaves decortications wastes with 25% chicken manure concentration produced heaviest sporocarps mean dry weight. These findings for the first time illustrate importance of chicken manure supplementation in C. cinereus (Schaeff) S. Gray s.lat cultivation on sisal decortications wastes substrates.

    Improved Antimicrobial Activity of the Tanzanian Edible Mushroom Coprinus Cinereus (Schaeff) Gray by Chicken Manure Supplemented Solid Sisal Wastes Substrates
    (2010) Mwita, Liberata N.; Mshandete, Anthony M.; Lyantagaye, Sylvester L.
    The Tanzanian edible mushroom species Coprinus cinereus was grown on sisal waste substrates supplemented with chicken manure with the aim to evaluate the effects of the chicken manure supplement on the antimicrobial activity of the mushroom’s extracts. Crude ethyl acetate extracts were prepared from the mushroom’s fruiting bodies harvested at pre-capping, capping and post capping stages, and the extracts were tested for antimicrobial activity, using the agar well method. The antimicrobial activity was observed only in capping and post capping stages of the mushrooms and the activity generally increased with increased percentage of manure supplementation. These findings show that Tanzanian edible C. cinereus mushroom contains antimicrobial compounds and chicken manure could be used in the cultivation of the mushroom to increase the production of active secondary metabolites, which could be used as lead compounds for discovery of new and more effective drugs against microbial infections.
