Description
Summary:Distillation wastes of aromatic crops, rich in lignocellulosic content may be suitable for the cultivation of Pleurotus mushrooms by solid-state fermentation. The lignocellulosic biomass of lemongrass, rosagrass, java citronella and wheat straw taken as control were utilized for the production of mushrooms derived from the species Pleurotus florida. Further, fruiting bodies were used for analysing the biological efficiency of the substrate, mineral and heavy metal content. The highest biological efficiency was observed in case of rosagrass with 32.8% followed by wheat straw, lemongrass and java citronella with 25.3%, 21.6% and 18% respectively. In addition to this, high amount of minerals; zinc (97 ± 0.6 mg/kg), manganese (11 ± 0.2 mg/kg) and copper (18 ± 0.2 mg/kg) was observed in the fruiting bodies of mushrooms obtained from java citronella as compared to control. Significant increase in amount of mineral content was obtained in mushrooms obtained from distillation wastes of lemongrass and rosagrass on comparison with control. Subsequently, heavy metal content was almost negligible in mushrooms obtained from all the substrates, thereby, making them safe for consumption. Thus, utilization of distillation waste of aromatic crops paves a new approach for the production of biofortified mushrooms. Graphical Abstract
