Bull Environ Contam Toxicol. 2008 Sep;81(3):316-22 Authors: Sathishkumar M, Binupriya AR, Swaminathan K, Choi JG, Yun SE The sorption of As(V) from aqueous solution onto live and pretreated Biomass of Aspergillus fumigatus was studied. The studies on optimization of contact time, adsorbent dosage and pH showed that the FeCl(3) treated and FeSO(4) treated Biomass had the maximum capacity to adsorb As(V) while acid treated Biomass was found to be minimum. Adsorption parameters were determined using both Langmuir and Freundlich isotherm models. The maximum adsorption capacity of 0.054 mg/g was observed in FeCl(3) treated and FeSO(4) treated biomasses. Column mode studies were conducted using FeSO(4) treated Biomass to compare its efficacy with batch mode to adsorb As(V). Batch mode experiments proved to be efficient. Desorption studies were also carried out with dilute sodium hydroxide to recover both the adsorbent and adsorbate. PMID: 18597036 [PubMed - indexed for MEDLINE] ...

Abstract   It is essential to know the nutrient limitation status of biofilms to understand how they may buffer uptake and export of nutrients from polluted watersheds. We tested the effects of nutrient additions on biofilm Biomass (chlorophyll a , ash free dry mass (AFDM), and autotrophic index (AI, AFDM/chl a )) and metabolism via nutrient-diffusing substrate bioassays (control, nitrogen (N), phosphorus (P), and N + P treatments) at 11 sites in the Upper Snake River basin (southeast Idaho, USA) that differed in the magnitude and extent of human-caused impacts. Water temperature, turbidity, and dissolved inorganic N concentrations all changed seasonally at the study sites, while turbidity and dissolved inorganic N and P also varied with impact level. Chl a and AI on control treatments suggested that the most heavily impacted sites supported more autotrophic biofilms than less-impacted sites, and that across all sites biofilms were more heterotrophic in autumn than in summer. Nutrient stimulation or suppression of biofilm Biomass was observed for chl a in 59% of the experiments and for AFDM in 33%, and the most frequent response noted across all study sites was N limitation. P suppression of chl a was observed only at the most-impacted sites, while AFDM was never suppressed by nutrients. When nutrient additions did have significant effects on metabolism, they were driven by differences in Biomass rather than by changes in metabolic ra ...

A new life cycle study assessing the benefit of cellulosic ethanol in the context of projected feedstock constraints concludes that in terms of reducing greenhouse emissions and fossil fuel dependency, more is lost than gained when prioritizing Biomass or land for bioethanol, rather than for use in technology pathways involving heat and power production and/or biogas, or natural gas and electricity for transport. The study was published online in the journal Environmental Science & Technology on 4 October. The study by researchers in Denmark begins with the conclusion that toward 2030, the amount of Biomass which can become available for bioethanol or other energy uses will be physically and economically constrained, regardless of whether of global or a European perspective is applied. This implies that the use of Biomass or land for bioethanol production will most likely happen at the expense of alternative uses. Specifically, the study compares the use in transportation of cellulosic ethanol produced from whole-crop maize by fermentation in several process configurations to alternative use of the feedstock in heat and power applications fueled by coal or natural gas. Among the scenarios investigated, the researchers found that using willow in CHP production combined with using electric cars for transport yields the highest GHG mitigation and reduction in oil dependency. They also found that the optimal biogas scenario is for biogas t ...

Novozymes was awarded a USD 12.3 million contract from the U.S. Department of Energy (DoE) today to improve the enzymes necessary to produce cellulosic ethanol. Novozymes’ project DECREASE (Development of a Commercial-Ready Enzyme Application System for Ethanol) aims to improve the performance of Novozymes’ most advanced enzyme system, to further reduce the cost of cellulosic ethanol production. Under the terms of the 2.5-year contract Novozymes has committed to increase the efficiency of the enzymes used in the conversion of cellulosic Biomass to ethanol by two-fold. In combination with internally funded research and development to reduce enzyme production costs, this work will enable Novozymes to supply new and even more cost-efficient commercial cellulases in pilot, demonstration, and commercial plants by 2012. Novozymes will match the DoE funding dollar for dollar, bringing the total investment of the research project to USD 25 million.

Researchers In Denmark have been looking hard at the amount of Biomass that will be available for biofuels after 2030 is going to become tight. This is what they say in a peer-reviewed paper in Environment Science Technology, produced by the American Chemical Society. We show that toward 2030, regardless of whether a global or European perspective is applied, the amount of Biomass, which can become available for bioethanol or other energy uses, will be physically and economically constrained. This implies that use of Biomass or land for bioethanol production will most likely happen at the expense of alternative uses. In this perspective, we show that for the case of a new advanced bioethanol technology, in terms of reducing greenhouse emissions and fossil fuel dependency, more is lost than gained when prioritizing Biomass or land for bioethanol. Technology pathways involving heat and power production and/or biogas, natural gas or electricity for transport are advantageous. There's more, but you have to subscribe. The bit that interests me is the parts about heat and power production, that is static power generation. I guess there could be real benefits in this area because potentailly at least you could build power plants in the middle of agricultural areas. There would be transmission losses, but this would probably be less than the energy needed to transport liquid fuels around. ...
