Biodegradação de resíduos lignocelulósicos gerados na bananicultura e sua valorização para a produção de biogás AGRIAMBI
Souza,Ozair; Federizzi,Mauri; Coelho,Bruna; Wagner,Theodoro M.; Wisbeck,Elisabeth.
Propôs-se, neste trabalho, avaliar a potencialidade do uso de resíduos lignocelulósicos da bananicultura como substrato de fermentação do processo de metanização. Os resíduos casca de banana, engaço, folhas e pseudocaule da bananeira Musa cavendischii, foram biodegradados a 30 °C e pH 7,2, em diferentes volumes de trabalho, empregando-se como biodigestor frascos Erlenmeyer, garrafas plásticas e biorreator de bancada. A composição ideal do substrato para a metanização foi definida como: 50% m m-1 de cascas, 25% de folhas e 25% de pseudocaule. O engaço, por apresentar baixa velocidade de biodegradação em comparação com as demais biomassas, não foi recomendado para a metanização conjunta dos resíduos. A hidrólise ácida prévia do substrato foi prejudicial à...

Biodegradation of 2,4 dichlorophenol by Pleurotus ostreatus DSM 1833 BABT
Silva,Heloisa Helena Batista da; Schneider,Andréa Lima dos Santos; Wisbeck,Elisabeth; Furlan,Sandra Aparecida.
This work aimed to investigate the capacity of Pleurotus ostreatus DSM 1833 to degrade 2,4-dichlorophenol, important pollutant found in the wastewaters of the paper and cellulose industry. Using a factorial design 2², the concentrations of glucose and 2,4-dichlorophenol varied between 0 and 10g.L-1 and 5 and 30mg.L-1, respectively. The best global biodegradation rate was obtained using 30 mg.L-1 of 2,4- dichlorophenol in the absence of glucose. This culture medium was used for scaling up the process, resulting in a global biodegradation rate of 0.47mg.L-1.h-1. A comparative test between an inoculated medium and an abiotic control demonstrated that 54.1% of 2,4- dichlorophenol degradation could be attributed to the presence of P. ostreatus.

Cultivation of Agaricus blazei on Pleurotus spp. spent substrate BABT
Gern,Regina Maria Miranda; Libardi Junior,Nelson; Patrício,Gabriela Nunes; Wisbeck,Elisabeth; Chaves,Mariane Bonatti; Furlan,Sandra Aparecida.
The aim of this work was the use of Pleurotus ostreatus and Pleurotus sajor-caju for the previous lignocellulolytic decomposition of banana tree leaf straw and the further use of the degraded straw as substrate for the culture of Agaricus blazei. For optimising the production of A. blazei in terms of yield (Y%) and biological efficiency (BE%), adjustments to the composition of the substrate were evaluated in a 2(5) experimental design. The following components were tested in relation to % of substrate dry mass: urea (1 and 10%), rice bran (10 or 20%) or ammonium sulphate (0 or 10%), inoculum (10 or 20%) and the casing material (subsoil or burned rice husks). The best results (79.71 Y% and 6.73 BE%) were found when the substrate containing 10% of rice bran,...

Extracellular polysaccharide production by a strain of Pleurotus djamor isolated in the south of Brazil and antitumor activity on Sarcoma 180 BJM
Borges,Gisele Martini; De Barba,Fabiana Figueredo Molin; Schiebelbein,Ana Paula; Pereira,Bruna Parmezzani; Chaves,Mariane Bonatti; Silveira,Marcia Luciane Lange; Pinho,Mauro Souza Leite; Furlan,Sandra Aparecida; Wisbeck,Elisabeth.
Polysaccharides with medicinal properties can be obtained from fruiting bodies, mycelium and culture broth of several fungus species. This work was carried out in batch culture using a stirred tank reactor with two different initial glucose concentrations (40-50 g/L) and pH values (3.0-4.0) to enhance extracellular polysaccharides production by Pleurotus djamor UNIVILLE 001 and evaluate antitumor effect of intraperitonial administration of Pleurotus djamor extract on sarcoma 180 animal model. According to factorial design, the low pH value (pH 3.0) led to a gain of 1.6 g/L on the extracellular polysaccharide concentration, while glucose concentration in the tested range had no significant effect on the concentration of polysaccharide. With 40 g/L initial...

The production of Pleurotus sajor-caju in peach palm leaves (Bactris gasipaes) and evaluation of its use to enrich wheat flour Ciênc. Tecnol. Aliment.
Cogorni,Paula Fernanda Bomfim Oliveira; Schulz,João Guilherme; Alves,Endi Pricila; Gern,Regina Maria Miranda; Furlan,Sandra Aparecida; Wisbeck,Elisabeth.
The aim of this study was to evaluate of Pleurotus sajor-caju production in peach palm leaves and the addition of different fractions of mushroom powder to wheat flour to increase its nutritional value without changing its characteristics. The best yield (48.4%), biologic efficiency (4.5%), and Pr (0.36 g/day) values were obtained using 20% inoculum fraction and 10% rice bran fraction. The Pleurotus sajor-caju fruiting body cultivated under these conditions had the following composition in 100 g: 29.91 g (carbohydrates), 42.92 g (proteins), 1.24 g (lipids), 15.93 g (fibers), 7.42 g (ashes), 1.6 g (phosphorus), 2.7 g (potassium), 8.73 mg (iron), 23.75 mg (sodium), 0.34 mg (thiamine), and 0.57 mg (riboflavin). The wheat flour with mushroom powder had reduced...
