Assessment of Different Spent Mushroom Substrates to Bioremediate Soils Contaminated with Petroleum Hydrocarbons

Bioremediation techniques are being developed as substitutes for physical–chemical methodologies that expensive and not sustainable. For example, using the agricultural waste spent mushroom substrate (SMS) which contains valuable microbiota soil bioremediation. In this work, SMSs of four cultivated fungal species, Pleurotus eryngii, Lentinula edodes, ostreatus, Agaricus bisporus were evaluated bioremediation soils contaminated by petroleum hydrocarbons (TPHs). The test was carried out mixing different with TPH-contaminated in comparison an unamended control to assess its natural attenuation. To determine most efficient strategy, hydrolase, dehydrogenase, ligninolytic activities, ergosterol content, percentage TPHs degradation (total chains) determined at end assay 40 days. application SMS significantly improved respect control. effective degrade A. bisporus, followed L. edodes P. ostreatus. Similar results obtained removal aliphatic aromatic hydrocarbons. showed effectiveness remove from C10 C35. This work demonstrates alternative valorizing abundant bioremediate soils.
