Integration of treated agro-based wastewaters (TAWs) management with mushroom cultivation

Abstract

The inefficient management of wastewater generated from agro-based industries has become a cause of environmental degradation. Treated agrobased wastewaters (TAWs) are characterized by higher nutrients load and therefore, utilizable in the agriculture and horticulture as irrigation source. Agricultural reuse of TAWs is the most common practice done by the farmers of developing countries. Using freshwater for substrate wetting has been creating an extra load on our drinking water resources. Globally, a huge volume of freshwater is utilized for substrate formulation in the commercial mushroom cultivation and integration of TAWs with mushroom cultivation has presented improvements in the mushroom productivity, signifying their cultivation more profitable. Furthermore, spent substrates can be used for biogas production, animal feed for mature castrated male sheep, post-weaning calves feeding, biodiesel production, bioethanol production, reducing sugar production, biofertilizer production, methane production, butanol production, etc. This book chapter deals with sustainable approaches to the potential use of TAWs in the formulation of mushroom's substrate material along with efficient management of spent mushroom substrate.

Spatial Assessment of Potentially Toxic Elements (PTE) Concentration in Agaricus bisporus Mushroom Collected from Local Vegetable Markets of Uttarakhand State, India

“…Accordingly, A. bisporus could be a natural “treatment plant” for different agro-industrial, dairy, and domestic wastewaters [ 6 ], resulting in reduced hazardous dispersion of PTE in the environment. However, not all button mushrooms that are consumed are a product of human cultivation, especially in developing countries where the local population tends to forage and sell the mushroom in rural markets as their main source of income [ 7 , 8 ]. The PTE concentrations of these wild mushrooms may be very high if they are collected near mines or industrial factories [ 9 ].…”

Kinetic Studies on Delignification and Heavy Metals Uptake by Shiitake (Lentinula edodes) Mushroom Cultivated on Agro-Industrial Wastes

“…The integration of mushroom production and agro-based wastewaters as a nutrient supply constitutes a sustainable and effective way for the treatment of the latter [42]. Moreover, the use of nutritional supplements in mushroom cultivation can provide the fungi with readily available nitrogen and carbon, thus promoting an earlier and larger mushroom production [35,43].…”

“…In another study, the supplementation of wheat straw and sugarcane bagasse substrates with treated sugar effluents increased the yield and medicinal properties of Agaricus bisporus ((J.E. Lange) Imbach) mushrooms [42]. On the other hand, there are just a couple of reports on the use of DPW for mushroom cultivation [1,45].…”

ENRICHMENT OF CASING SOIL WITH FE AND SOY-FLOUR UNDER Pseudomonas INOCULATION ON YIELD AND QUALITY OF BUTTON MUSHROOM

“…copper (Cu), boron (B), and Fe, added to the substrate at spawning do not influence the yield significantly (Weil et al, 2006). Nonetheless, it seems that micronutrient supplements provide mushroom producers with a potential opportunity to improve the efficiency and quality of freshly harvested mushrooms (Kumar et al, 2020).…”
