PROFICIENCY OF DIFFERENT MEDIA, CARBON AND NITROGEN SOURCES ON MYCELIAL GROWTH OF OYSTER MUSHROOM
Rukhsana Afzal
Abstract
Mushrooms are substantial and gorgeous food constituent globally. In Pakistan, Oyster mushroom cultivation is gaining attractiveness owing to fast mycelial growth rate as well as its adaptability to flourish in miscellaneous climatic circumstances. In mushroom production, mycelial growth is a key component, requires suitable cultural conditions. Thus, significant physiological factors i.e. culture medium, carbon and nitrogen sources of eighteen collected samples of oyster mushroom were optimized to acquire superb mycelial growth rate. Chickpea Extract Agar followed by Potato Dextrose Agar act as appropriate culture medium from seven tested media. Organic nitrogen sources i.e. yeast extract and peptone proved to be superior one over inorganic sources like Potassium nitrate and Sodium nitrate. Among carbon sources, two monosaccharaides (sucrose and glucose) stimulated the mycelial growth of all mushroom samples and metabolize the fungal activities. Key words: Mushroom, oyster, mycelial growth, culture, nitrogen and carbon sources.
