Cereal grains affect on spawn quality

Grains affect on spawn quality: cereal grain, a solid substrate, is used popularly for production of pure culture of mycelium, called Spawn. Just as seed quality is important to crop production, so is spawn quality to mushroom production. Cereal grains affect on spawn quality and the spawn has a fundamental role in global agricultural productivity. The success of mushroom cultivation and its yield depend to a large extent on the quality of the spawn used.   Grain preparation, inoculation and testing on Pleurotus spp.: Used grain sources consisting of wheat,…

How to grow grey oyster mushroom (Pleurotus ostreatus) on wheat straw and cardboard mixture.

Pleurotus is an aromatic edible fungus and of which some species constitute a very valuable protein source. The mushroom is easy, fast and less expensive to grow, require less preparation time and production technology compare to other mushroom species. Pleurotus spp. are the best-known lignin degraders  and they could grow versatilely on a wide range of lignocellulosic materials. These are some steps how to grow grey oyster mushroom on wheat straw and cardboard. Substrate preparation Wheat straw (S) and cardboard (C) are obtained and prepared into a culture substrate with…

How we can improve mushroom shelf life

Fresh horticultural commodities are fundamental components in a balanced healthy diet, providing vitamins, minerals and phytochemicals. Harvested horticultural products remain as living tissues subject to continuous metabolism. Before harvesting, when horticultural commodities are attached to the parent plant, losses of substrates and moisture due to respiration and transpiration are replaced. After harvest, however losses are not replaced and quality declines, limiting horticultural commodities shelf life. Moisture loss by transpiration in fresh products is associated with mass and quality losses and it is assumed to be a major cause of post-harvest…

How humidity and temperature affect on fruiting body of oyster mushroom

Oyster mushrooms efficiently grow at temperature of 20–30°C and 55%–70% humidity on different lignocellulosic substrates such as cotton wastes, rice and wheat straw, wood sawdust and chips, corn cobs, sugarcane bagasse, maize and sorghum stover, different leaves, and other residues. Humidity and temperature affect on fruiting body of oyster mushroom. Particularly, the factors affect the fruiting bodies’ shape. Optimal cultivation conditions vary with strains. Optimal temperature and humidity for fruiting body formation of this mushroom is known as 13-16°C and > 80%. High and low temperature indicates > 16°C and…

Mushroom Use in Skincare

Mushroom use in skincare: a variety of mushroom extracts and their bio-active metabolites showed a lots of promising benefits for the skin including: Anti‑tyrosinase (Skin Brightening): Some mushrooms have been found to reduce melanin content and inhibit tyrosinase activity (melanin production). Combined, this helps brighten skin and fade pigmentation. Some mushrooms contain kojic acid which is a natural skin lightener. This acid inhibits melanin production on the surface of the skin. This lightens the new skin cells formed after the dead ones are exfoliated. Anti‑hyaluronidase (Hydrating): Some mushrooms contains a…

PROBLEMS AND SOLUTIONS IN THE MUSHROOMS CULTIVATION

Source: FAO 2001 Problems and solutions in the mushrooms cultivation including: a/ Mycelium fails to form Improper initiation strategy. Solutions: consult parameter of growth. Alter moisture, temperature, light, carbon-dioxide, etc. Note: If the substrate is too moist, decrease moisture Chlorinated or contaminated water. Solutions:  Use activated charcoal water filters to eliminate chemical contaminants or any other ways of simple or appropriate technology. Bad substrate. Solutions: Check substrate. Spread the substrate and remix the substrate, package again, make sure all raw materials are good and fresh.  Note: It is necessary to…

Medicinal Properties of Pleurotus spp.

Medicinal Properties of Pleurotus spp include Antitumour activity: Various crude extracts of Pleurotus species have been shown to possess relatively strong antitumour activities. Methanol extracts of P. florida and P. pulmonarius fruiting bodies significantly reduced solid tumours in mice. P. ostreatus mycelium extract, alone and combined with the chemotherapeutic agent cyclophosphamide, inhibited in vivo tumour growth in mice. The combined administration of the extract with cyclophosphamide decreased the degree of leukopenia compared to administration of cyclophosphamide alone. A water extract of P. ostreatus exhibited the most significant cytotoxicity by inducing…

The effects of substrates on oyster mushroom growth

Mushroom as an excellent food source due to their flavor, texture, nutritional value and high productivity per unit area. Mushroom contains digestible proteins (10%-40%), carbohydrates (3%-21%), dietary fiber (3%-35%), on dry weight basis which is higher than those of vegetables and fruits and is of superior quality. High potassium to sodium ratio contain in Pleurotus species helps to cure patients suffering from hypertension & heart diseases. There are several species of Pleurotus identified in the world. Most of them are suitable for cultivation. Some Pleurotus species are Pleurotus ostreatus, Pleurotus…

How Oyster Mushroom Pleurotus Grow

How Oyster Mushroom Pleurotus Grow: Oyster mushrooms are generally a commercially grown mushroom. The muhrooms grow on a substrate of chopped wheat straw or wood sawdust that has been formed into large blocks wrapped in a thin plastic. The mushroom substrate is pasteurized to eliminate harmful pathogens and then inoculated with the mushroom spawn. It takes 10-14 days at the temperature 22-24 ° C for the mushroom spawn to permeate the growing medium creating thread-like hairs called mycelium . For pinning, this requires a constant temperature range 10-15° C, high…
