Abstract:
The decolouration of fermentation residues (vinasse) and liquid extract of coffee pulp by the mushroom Pleurotus ostreatus was studied in addition to laccase activity. The fungus was inhibited in both residues when they remained undiluted. In submerged cultivation on wastewaters a good production of biomass (14.8 g/l for vinasse and 5.4 g/l for extract of coffee pulp) and also laccase activity (14.1 U/ml for vinasse and 3.0 U/ml for extract of coffee pulp) up to the 10 days of fermentation was observed, being significantly greater in the culture with vinasse. It was shown that treatment with this mushroom reduces both the chemical oxygen demand and the colour, contributing to their biological treatment.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
