Improvement of in vitro digestibility through biological treatment of water hyacinth biomass by two Pleurotus species

Production of fermentable sugars by combined chemo-enzymatic hydrolysis of cellulosic material for bioethanol production

“…Cellulose related polysaccharides are considered to be a major component of water hyacinth (Malik, 2007;Nigam, 2002;Mukherjee and Nandi 2004;Ingole and Bhole, 2002). The plant body contains 26.3 wt% C-6 sugars such as glucose (19.8%) and galactose (6.5%) and 20.5 wt% C-5 sugars with 11.5 wt% xylose and arabinose (Girisuta et al, 2008;Aswathy et al, 2010).…”

Biodegradation of agroindustrial wastes by Pleurotus spp for its use as ruminant feed

“…These last determinations could be indicative of the degradation of the cell wall components of the substrates produced by the extracellular enzymes of P. ostreatus. Previous authors concluded that lignification of structural polysaccharides not only inhibited ruminal microbial digestion of polysaccharides by forming 3-D matrix, but also that the presence of highly lignified tissues formed a physical barrier preventing the accessibility of the otherwise highly digestible tissues to the action of hydrolytic enzyme of the rumen microorganisms (Karunanandaa et al 1995), and have shown that increased digestibility was associated with the degradation of structural carbohydrates (Mukherjee and Nandi, 2004).…”

“…Other authors have shown that some fungi, particularly some species of Pleurotus are able to colonize different types of vegetable wastes, increasing their digestibility (Platt et al 1984;Commanday and Macy, 1985;Rajarathnam and Bano, 1989;Villas-Boas et al 2002;Zhang et al 2002;Mukherjee and Nandi, 2004;Salmones et al 2005). Previous studies have shown the feasibility of using these kind of wastes to produce animal feed (Calzada et al 1987;Adamovic et al 1998), and as substrate for mushroom production (Breene, 1990;Sermanni et al 1994;Kakkar and Dañad, 1998;Yildiz et al 2002).…”

Biological Treatment of Broad Bean Hulls and its Evaluation through Tilapia Fingerlings (Oreochromis Niloticus) Feeding

“…After incubation for 20 day at 25 ± 1°C, the sterilized bioconverted substrates were used as inoculum for non-sterilized air dried milled biomass with rate 10% as follow:-Each air dried milled biomass (broad bean hulls) was placed in glass box (width 40 cm × 30 cm height), moistened (till 65%) with water, the substrate moistened when needed. The biomass materials were treated with rate 10% from the described bioconverted substrate (106 cfu/gm), mixed well after that was covered by polyethylene and incubated for 42 days at 25 ± 1°C [7,8].…”

“…Many authors have shown that some fungi, particularly some species of Pleurotus are able to colonize different types of lignocellulsic wastes, increasing their digestibility [7,8]. Previous studies have shown the feasibility of using these kinds of wastes to produce animal feed [9], and as substrate for mushroom production [10].…”
