Abstract:
The utilization of paper on a commercial scale is increasing day by day throughout the world that produces million of tons of paper waste yearly and burdened for landfills. The present study focuses on the exploitation of waste papers (office paper, newspaper and tissue paper) as a cheapest alternative source of energy to extract fermentable sugar by applying chemical and enzymatic pretreatments. The quantification of released sugar was analyzed by spectrophotometer and high performance liquid chromatography refractive index (HPLC-RI) detector.

Waste Shiitake (Lentinula edodes) mushroom medium, a lignocellulosic aglicultural residue, was evaluated as a fermentable substrate. 87% of the fermentable sugars remained in the waste mushroom medium. The sugar yield of the waste mushroom medium (46.3%) was higher than that of raw mushroom medium (20.3%) after 48 h of enzymatic saccharification by Meicelase because L. edodes changed wood structure. These results indicated that the waste mushroom medium is a suitable substrate for fermentation. Next, the efficient ethanol production using steam explosion pretreatment was studied. After 30 h of

One of the main concerns regarding extensive production of biobutanol has been associated with the high costs of the substrate (preparation of fermentable sugars) and the relatively low tolerance of Clostridia to butanol. In this study a simple, mild approach was tested to obtain fermentable sugars from agricultural waste. Giant hogweed and hay was pre-treated with simple boiling and enzymatically hydrolysed. The results demonstrated that after adaptation of the genus Clostridium bacteria to the new substrate, the growth kinetics and sugar consumption of these bacteria were similar to the ones

The results indicate that there are 59.32gL-1 reducing sugar under the conditions of 100°C, solid-liquid ratio of 1:12 gmL-1, acid concentratio

Abstract:
Sugar cane bagasse is a cheap lignocelluloses which has high carbohydrate content and, if properly pre-treated, could be converted to fermentable sugar. In this study various fungal isolates isolated from lignocellulosic waste were assayed for their CMCase, FPase and xylanase activity. Four potent plant cell wall-degrading fungi were identified as Trichoderma sp., Aspergillus niger, Cladosporium sp. and Curvularia sp. Among these isolates Trichoderma sp. produced the highest enzymatic activity in the culture filtrates containing steamed NaOH treated-bagasse. The yield of endo-β-glucanase i.e.,

As the gradual up-growing trend of industrialization and urbanization leading steady increment of demand of energy; eco-friendly, bio degradable, cost competitive and promising source of energy with high sustainability is toughly needed for the new era of modern world. Hydrolysis of cellulose by cellulase enzymes is a vital candidate for this option. It is a solid-liquid heterogeneous reaction; strongly affected by the non-reaction resistances caused most notably by the crystalline structure; reaction environment parameters as temperature, pH, characteristics of enzyme, cell & substrate lo

Abstract:
It is of general interest to produce fermentable carbohydrates from plant biomass. However, obtaining monosaccharides requires some effort, due to the intricate structure of the cell wall lignocellulosic complex. The aim of this study was to apply a simple two-stage hydrolysis process, using only concentrated hydrochloric acid, to generate fermentable carbohydrates from L. rotundiflorus biomass. First and second stage acid concentrations were 32% and 42.6%. Total monosaccharide yields with respect to dry matter after the first stage, second stage, and the overall process, were 27.5%, 21.0% and

Abstract:
Composting is a process for the biological treatment of waste. This work consists of the valorization of the fermentable fraction of the household waste (FFOM) of the city of Tiaret by the production of enriched compost and its physicochemical characterization. In this context, 50 kg of selectively collected FFOM were composted by the Andean composting technique with mechanical turning and oxygen supply by aeration. Two enrichment treatments were applied. The first consists of the addition of ash on the waste to be compacted and the second, the addition of urea on the 25th day of the process.

To develop biofuel production from waste lignocellulosic biomass materials the rice straw was selected one of renewable material and the degradation condition about pretreatment and enzymatic hydrolysis to obtain effectively fermentable sugars was investigated. Rice straw was pretreated by five kinds of methods and then the components ratio of rice straw was examined. First, the steam explosion was selected based on the degradability and the requirement energy.

Biomass pretreatment has an important role in the production of cellulosic bioethanol. In this study, the effectiveness of microwave assisted alkaline pretreatment of algae waste was analysed. After pretreatment, the product was hydrolysed using sulphuric acid. The effects of microwave power, irradiating time, solid–liquid ratio and NaOH concentration were examined. Under the best conditions, the fermentable sugars were converted to cellulosic bioethanol using Saccharomyces Cerevisiae with a bioethanol yield of 1.93 ± 0.01 g/g and a fermentation efficiency of 40.4%.
