Use of vinasse and sugarcane bagasse for the production of enzymes by lignocellulolytic fungi

Abstract

In this present work, three strains of Pleurotus and

Pretreatment strategies for delignification of sugarcane bagasse: a review

“…The chemical pretreatment for sugarcane bagasse developed by Aguiar et al (2010) to produce exoglucanases and endogluconases resulted in better breakage of the fibers when using 2% H 2 O 2 together with 1.5% NaOH at 121ºC for 15 min. This treatment increased the cellulose level up to 1.2 times and decreased the hemicellulose content 8.5 times, promoting a better accessibility of the fungi to the fibers.…”

Enhanced saccharification of corn straw pretreated by alkali combining crude ligninolytic enzymes

“…47 High alkali concentration increases treatment costs, and leads to more sewage production. 19,20 Therefore, 1.5% NaOH was selected for the following experiments. It is worth noting that the straw particle size in this study was much bigger and the processing temperature much lower than those of other studies.…”

“…The combination of alkali pretreatment with other physical or chemical methods usually improves delignification efficiency and reduces process severity. 19,20,21 As a result, toxic compounds and pollutant production are reduced. It has been shown that ultra-high pressure explosion combined with treatment with 0.5% NaOH at 125…”

“…19 Aguiar et al 20 reported that the treatment of bagasse with 2% H 2 O 2 plus 1.5% NaOH and autoclaving resulted in greater fiber breakage and higher cellulose content. Unfortunately, such physical and chemical pretreatments usually result in sewage production, equipment corrosion and high energy consumption.…”

Cultivation and nutritional studies of an edible mushroom from North Brazil

“…This species has a worldwide distribution and can be found in tropical or subtropical forests (Guerrero and Homrich, 1999;Putzke, 2002;Rosado et al, 2002). This mushroom has been produced in vitro in several agro-industrial substrates as castor plant peel, rice straw, sugarcane bagasse, cotton waste, soybean straw, corn cob, elephant grass, oat, rye grass, sunflower seed, eucalyptus sawdust, stillage and privet (Rosado et al, 2002;Donini et al, 2005;Bernardi et al, 2007;Minotto et al, 2008;Nascimento et al, 2008;Aguiar et al, 2010;Reis et al, 2010).…”
