Sugarcane bagasse was delignified with alkali and peracetic acid in a two-stage process to obtain pulps with high yield and low kappa number. The experimental results indicated that alkali pretreatment prior to peracetic acid (PAA) delignification could significantly reduce PAA loading by partially removing lignin and swelling the fibers. An optimum condition for the two-stage delignification w...

Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

This work evaluated the effect of dissolved oxygen and the initial inoculum concentration on xylose reductase (XR) production by Candida guilliermondii from sugarcane bagasse hemicellulosic hydrolysate. Both the parameters were studied under an experimental design 2 with triplicate at central point. The statistical analysis of the results indicated a significant negative effect on XR production...

Solid-state fermentation of sugarcane bagasse by Penicillium citrinum MTCC 2553 was optimized to maximize the yield of xylanase. Preliminary experiments carried out with various lignocellulosic materials revealed sugarcane bagasse to be the most suitable substrate for producing xylanase. Response surface methodology was used in the optimization. Xylanase activity was maximized in a 5-day batch ...

In this study, three agro-waste materials were used as biosorbents for removal of copper (Cu) from water. This work aims to optimise conditions for preparation of these materials to obtain maximum Cu adsorption capacity. The optimal conditions were determined in terms of Cu removal efficiency and/or energy consumption. The results indicate that banana peels dried at 120°C for 2h and ground into...

in order to investigate the effects of substrate and spawn levels on growth and development of florida oyster mushroom an experiment was conducted in 2005 at the laboratory of the department of horticulture, agriculture faculty, shahid chamran university, ahvaz. the design of the experiment was a factorial one of a randomized complete blocks of 3 replications. the two factors of substrate and s...

BACKGROUND There is an imperative necessity for alternative sources of energy able to reduce the world dependence of fossil oil. One of the most successful options is ethanol obtained mainly from sugarcane and corn fermentation. The foremost residue from sugarcane industry is the bagasse, a rich lignocellulosic raw material uses for the production of ethanol second generation (2G). New cellulol...

BACKGROUND Sugarcane is the most efficient crop for production of (1G) ethanol. Additionally, sugarcane bagasse can be used to produce (2G) ethanol. However, the manufacture of 2G ethanol in large scale is not a consolidated process yet. Thus, a detailed economic analysis, based on consistent simulations of the process, is worthwhile. Moreover, both ethanol and electric energy markets have been...

In the present study a strain of Bacillus subtilis-BS05 was grown in submerged fermentation of agricultural wastes for xylanolytic activity. Various agricultural wastes such as sugarcane bagasse, wheat straw, rice husk, soybean meal, corn cobs and wheat bran were evaluated for xylanolytic acitivity using different media (M-I, M-II, M-III & M-IV). Among all these tested substrates maximum xylano...

Vermicompost produced from sugarcane bagasse (SBV) or sawdust (S) were substituted at a range of different concentration in soilless bedding plant container medium, as a peat: vermiculite: perlite (6:3:1), to evaluate their effects on the growth of Dieffenbachia amoena in the greenhouse. Dieffenbachia amoena was grown in container medium PE: VE: P (6:3:1), in that peat substituted with 0%, 10%,...
