Sorghum is one of the commercially feasible lignocellulosic biomass and has a great potential of being sustainable feedstock for renewable energy. As with any lignocellulosic biomass, sorghum also requires pretreatment which increases its susceptibility to hydrolysis by enzymes for generating sugars which can be further fermented to alcohol. In the present study, sorghum biomass was evaluated f...

The Coats-Redfern method was used to analyze the kinetic characteristics of biomass catalytic pyrolysis, indicating that it can be described by multi-step reactions, rather than as a simple first-order reaction. Friedman model-free calculations were used to describe the starting reaction types and the corresponding initial kinetic parameters. Finally, nonlinear regression of biomass catalytic p...

Anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.This technology is superior to the landfilling and also the aerobic composting. The aim of the present study was to examine whether the effluent Volatile Fatty Acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

BACKGROUND Fine milling of dry lignocellulosic biomass, without prior chemical pretreatment, can produce a high percent theoretical yield of sugars during subsequent enzymatic saccharification. However, the high sugar yields, necessary for a commercial biofuels process, are costly, with the milling energy input, necessary to achieve such yields even exceeding the energy content of the biomass. ...

—Total aboveground live tree biomass in Puerto Rican lower montane wet, subtropical wet, subtropical moist and subtropical dry forests was estimated using data from two forest inventories and published regression equations. Multiple potentially-applicable published biomass models existed for some forested life zones, and their estimates tended to diverge with increasing tree diameter at breast ...

An analytical method based on high-performance liquid chromatography-photodiode array detection was developed for the simultaneous determination of three anti-proliferative withanolides [withalongolide A ( 1: ), withaferin A ( 2: ) and withalongolide B ( 3: )] present in the aboveground biomass of the long-leaf groundcherry, Physalis longifolia. This method was achieved by biomass extraction fo...

Background: Amongst the methods that remove heavy metals from environment, biosorption approaches have received increased attention because of their environmentally friendly and cost-effective feature, as well as their superior performances. Methods: In the present study, we investigated the ability of a surface-engineered Escherichia coli, carrying the cyanobacterial metallothionein on the cel...

Recently, carbon nanofibers have gained immense attention in research due to its tremendous application. Here, this work highlights a simple, cost effective and reliable method to develop carbon nanofibers (CNF) from biomass. The biomass used is bacterial cellulose (BC) synthesiSed using Acetobacter xylinus. CNF was developed by freeze drying of BC followed by pyrolysis at different temperature...

introduction: biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. also, living lichens are known to accumulate metals across their surface. materials and methods: in this study, the biosorption of cadmium ions cd (ii) by the lichens acarospora strigata, lecanora muralis and caloplaca aurantia was investigated in aqueous solution in...

the present investigation was carried out to study the variability, heritability, correlations and path coefficient analysis in 14 kabuli type chickpea genotypes during three successive cropping seasons (2011-14), in a randomized complete block design with four replications. combined analysis suggested significant differences between genotypes for most of characteristics. the highest phenotypic...
