International Journal of Pharma and Bio Sciences V1(2)2010 PRETREATMENT AND SACCHARIFICATION OF STEAM EXPLODED WASTE OF A PHARMA INDUSTRY

چکیده
Herbal waste of processed medicinal plants of a local pharmaceutical industry was pretreated by steam explosion (160C for 0.5 – 2.0 h), and the process was accelerated by the use of Conc. H2SO4 (0.5 – 2.0%, 160 C for 0.5 – 2.0 h), NaOH (0.5 – 2.0%, 160C for 0.5 – 2.0 h). Significant increase in the content of reducing sugars was found after acid/alkali pretreatment of steam exploded herbal biomass. Maximum Reducing sugars obtained was 145.9 mg/g of herbal waste with 1.5% of H2SO4 at 160 C for 1.5 h. Bulk of herbal waste disposed off by pharma industry can act as secondary substrate as a source of fermentable sugars.

Comparison of saccharification and fermentation of steam exploded rice straw and rice husk
BACKGROUND Rice cultivation produces two waste streams, straw and husk, which could be exploited more effectively. Chemical pretreatment studies using rice residues have largely focussed on straw exploitation alone, and often at low substrate concentrations. Moreover, it is currently not known how rice husk, the more recalcitrant residue, responds to steam explosion without the addition of chem...
متن کاملMethane Potential and Enzymatic Saccharification of Steam-exploded Bagasse
To evaluate the biofuel potential of bagasse, an abundant co-product in sugarcane-based industries, the effect of steam explosion on the efficiency of enzymatic saccharification and anaerobic digestion was studied. Bagasse was steam exploded at four different severity levels, and the impact of pretreatment was evaluated by analyzing the release of glucose after enzymatic saccharification with C...
متن کاملEffect of different steam explosion conditions on methane potential and enzymatic saccharification of birch.
Birch (Betula pubescens) was steam exploded at 13 different conditions with temperatures ranging from 170 to 230 °C and residence times ranging from 5 to 15 min. Increasing severity in the pretreatment led to degradation of xylan and formation of pseudo-lignin. The effect of the pretreatments was evaluated by running enzymatic saccharification and anaerobic digestion followed by analysis of sug...
متن کاملSteam explosion distinctively enhances biomass enzymatic saccharification of cotton stalks by largely reducing cellulose polymerization degree in G. barbadense and G. hirsutum.
In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5-6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H2SO4 pretreatment could further increase biomass digestibility of the steam-exploded stalks, and also cause the highest sugar-ethanol conversion rates probably by rel...
متن کاملPretreatment effects on orange processing waste for making ethanol by simultaneous saccharification and fermentation.
Citrus processing waste (CPW) pretreated under different times, pH and temperatures was investigated. Pretreatments at 160 degrees C for longer than 4 min with steam purging were needed to remove limonene, an inhibitor for fermentation, to below 0.1%. While hemicelluloses were solubilized well following all pretreatments at 160 degrees C, just 70% of the pectin was solubilized in natural CPW co...
