Despite the benefits of mushroom consumption, the bioaccumulation of trace metals in mushrooms can endanger consumer’s health. The consumption of mushrooms in South Eastern Nigeria has received less attention. Seven edible mushroom species (Auricular auricular judae, Lentinus squarrosulus, Pleurotus pulmonarius, Pleurotus ostreatus, Termitomyces microcarpus, Termitomyces robusta and Volvariella volvacea) and their respective substrate samples, collected from Ohiya mechanic village in Abia central senatorial zone of the South-eastern Nigeria were investigated for the presence of five heavy metals (Cd, Pb, Fe, Hg, As). Apart from this, the heavy metals associated health risks were also...

Determination of the Paper Quality as a Substrate for Oyster Mushroom Cultivation
Pleurotus sp. is well known commercially cultivated white rot fungus. It is capable of utilizing a widerange of agro-wastes such as Artichoke waste, Banana leaves and pseudostem, Barley straw, Brassica-haulms, Cinnamon leaves, Coffee sawdust, Corncobs, Cotton wastes, Groundnut shells, Oat straw, Rice straw, Soybean stems, Sugarcane bagasse, Wheat straw, wood waste etc. These substrates are rich in cellulose, hemicelluloses and lignin content. To utilize these substrates mycelium of Pleurotus sp. has to secrete extracellular enzymes complex that could depolymerised these polymers. This complex includes the oxidative enzymes laccase and manganese peroxidase , which is...

An Approach to Improve Yield Parameters of Pleurotus florida Strain P1
Aim: The efficient mushroom production involves many factors of which spawn production, culture methods and substrate selection are of prime importance. The research has, therefore, been carried out to standardize these aspects in present communication, for production of Pleurotus florida Strain- P1.Materials and Methods: Various cereals (maize, oat, barley) and millets (Italian millets, Little millet, Pearl millet) were assessed against wheat grain spawn for enhancing yield and biological efficiency of mushroom. Most suitable wheat straw component among fine pieces of leaves and leaf sheath (0.2 cm), coarse pieces of leaves and leaf sheath (0.4...

A new filter for safe view of Solar Eclipse
Looking directly at the sun can lead to permanent eye injury due to damage of light-sensitive rod and cone cells within the retina. There are two ways to look at the Sun safely: by observing the sun directly through a suitable filter, or by projecting the Sun’s reflection onto a piece of paper via handmade pinhole camera/ telescope. The present correspondence shows the specification for the development of an optical instrument for the direct observation of sun. For this device, commonly available solar control glass plates can be used. The design of this filter...
