Viability of Cassava peels spawn production and mushroom cultivation
Abstract This work was carried out to ascertain the viability of spawn produced on cassava peels and used for spawning cassava peels and sawdust substrates and compare the yield with mushroom fruits from the conventional Sorghum bicolor known to be the best material for spawn production. Three different species of mushroom cultures were inoculated on cassava peels, two Pleurotus pulmonarius strains (FIIRO and Thailand) and Lentinus squarroslus. The study of mycelia colonization rate study was done in triplicate. L. squarroslus completed colonization within 18days of inoculation in test tube with a growth mean value of 11.16cm, the two strains of P. pulmonarius (FIIRO and Thailand) completed colonization in 21 days with FIIRO strain having growth mean value of 11.46cm and Thailand strain 11.20cm. Cassava peels spawn production was done in two ways, singly and supplemented with rice bran, yield from different species of mushroom (L. squarroslus and P. pulmonarius (FIIRO Strain) cultivated with cassava peels spawn in the study were compared with sorghum grains spawn. Different weight of 100, 200, 300g were used for cultivation, sorghum grains spawn produced the highest yield (202.13g) from the two species used followed by cassava peels supplemented with rice bran (179.86g) and single cassava peels spawn (124.13g). L. squarroslus did not fruit on cassava peels even with the sorghum grains spawn. The differences from the yield of the three spawn was negligible as the differences was not noticeable (cassava peels 124.133±5.21a, supplemented cassava peels spawn 179.867±0.64a, and sorghum grains spawn 202.133±8.86a). This result verified the use of cassava peels in the production of viable mushroom spawn.
Oyster mushrrom cultivation at different production systems: a review
This paper aims to review historical perspectives, nutritional and medicinal benefits, biodiversity, cultivation, diseases and their control, pathogen detection systems, food safety concerns and use of spent mushroom compost of oyster mushrooms. The genus Pleurotus (oyster mushrooms) is a diverse group of mushrooms high in nutritional value and other useful properties applicable to the environmental. The production and consumption of oyster mushrooms has increased owing to its benefits. Over the past few years, there have been efforts to identify locally available substrates, improve spawn production and limit disease incidences. Pathogen detection systems have also been improved in an effort to develop rapid and more accurate assays leading to reduced production losses. The use of chemicals threatened by development of resistance by pathogens as well as new legislations, hence alternative treatment methods have to be fully implemented. Lastly, despite its huge potential, spent mushroom compost is underexploited sometimes utilized for land filling and in crop production.
Mushrooms As Human Food
Although mushrooms have at one time been used as a staple food in some parts of Russia and South America, and they have been served as the main dish during mushroom seasons in Africa, they are generally considered only as an ingredient or complement to various dishes-rather than as a daily vegetable. However, mushrooms have been and will be increasing in importance as a source of food because they have a pleasing flavor, fine texture, adequate protein content (Crisan and Sands 1978), and health benefits (Mori 1974). The demand for mushrooms in some industrialized countries has increased
