Abstract

Conventional biological wastewater treatment and large amount of low value bacterial biomass. The treatment and disposal of this excess bacterial biomass, also known as activated sludge, accounts for about 40 – 60 % of wastewater treatment plant operation cost. A different form of biomass with a higher value could significantly change the economics of wastewater treatment process. The biomass produced during fungal wastewater treatment process has potentially much higher value than that from the bacterial activated sludge process .The fungi can also be used as a protein source various high- value biochemical can also be used. High value bio chemicals are produced by commercial cultivation of fungi under aseptic conditions using expensive substrates. Food – processing wastewater is an alternative as a source of low cost organic matter and nutrients to produce fungi with concomitant wastewater purification. This review summarizes about production of mushroom from spawn on coconut coir and rice paddy and using them as a biological source for wastewater treatment. The wastewater is passed through the mushroom almost 50 – 80% 0f water is purified. It’s not completely but partially purified. Can be used for drinking but mostly used for medical process for gardening etc.

History

1917: Flack described the first successful cultivation of Pleurotus Ostreatus.

1951: Lowhag was the first to grow Pleurotus on sawdust mixtures.

1962: Bano and Srivastava reported mass production on straw – based substrates and work paved the way for large scale commercial exploitation.

Keywords: Sajor – caju (Pleurotus spp) called as oyster mushroom, coconut coir, rice paddy.
