In the present study, Pleurotus ostreatus growth in wastewater from mushroom farm was evaluated as a potential biological treatment process for decolourisation as well as to obtain biomass (liquid inoculum). Culture medium components affecting mycelial growth were determined, evaluating colour removal. Laccase activity was monitored during the process. P. ostreatus was able to grow in non diluted WCP. Highest biomass yield was obtained when glucose (10 g/l) was added. The addition of this carbon source was necessary for efficient decolourisation. Agitation of the culture improved biodegradation of WCP as well as fungal biomass production. Laccase and manganese-independent peroxidase activities were detected during fungal treatment of the WCP by P. ostreatus CCEBI 3024. The laccase enzyme showed good correlation with colour loss. Both wastewater colour and pollution load (as chemical oxygen demand) decreased more than 50% after 10 days of culture. Phenols were reduced by 92%. specialized White-rot fungi P ostreatus Decolourisation Fungal growth Wastewater 084 19 4 519-526 2008 0923-9820 https://www.documentation.ird.fr/hor/fdi:010042633 10.1007/s10532-007-9157-z 0923-9820 [F B010042633] https://www.documentation.ird.fr/hor/fdi:010042633 https://www.documentation.ird.fr/intranet/publi/2008/07/010042633.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2008-08-08 2017-08-23 fdi:010042633 fre
