TL;DR: Cheese-whey utilization has been the subject of much research as mentioned in this paper and the most representative applications of cheese whey being exploited and under research are briefly discussed in this paper.

TL;DR: In this paper, the adsorption of dyes such as congo red, procion orange and rhodamine-B by waste orange peel was examined at different concentrations of dye, adsorbent dosage, agitation time and pH.

TL;DR: The development of Jatropha curcas L. as a possible energy crop in Nicaragua is discussed in this article, where a technical process for the processing of the seeds and the production of the methyl esters from the seed oil is described.

TL;DR: Results from the breeding program indicate that recurrent restricted phenotypic selection could lead to development of new cultivars, and research has indicated that seed dormancy can be modified, resulting in increased seed germination and a greater number of switchgrass plants.

TL;DR: Xylanase activities produced by different organisms, including filamentous fungi and yeasts, are compared for both submerged and solid-state fermentations, and data on the concurrent formation of cellulolytic enzyme activities are included.

TL;DR: In this paper, four types of hydrolysis kinetics were tested for anaerobic degradation of complex organic matter using the generalized simulation model described earlier, including a surface colonization of the particles by hydrolytic bacteria, as well as following surface degradation.

TL;DR: In this paper, the parameters and corresponding threshold values defining the quality of RME used as biodiesel according to the latest Austrian standardization (O-NORM) are presented and discussed.

TL;DR: In this paper, the feasibility of the glycerolysis of vegetable oils with crude glycerol derived from the transesterification of vegetable oil and animal fats was investigated for improving the overall economy.

TL;DR: In this paper, the effects of three moisture levels, 50%, 60%, and 70%, on the composting process were evaluated, and it was found that a moisture content of between 50 and 60% can be considered as the optimal moisture level for further composting of the spent litter.

TL;DR: Growth in Chlorella vulgaris media was comparable to growth in the commercial Bristol medium which contains nitrate as the nitrogen source and was accompanied by a decrease in nitrogen content in the medium, indicating that nitrogen removal was due to algal uptake and assimilation.

TL;DR: In this paper, the use of a medium severity refinery hydroprocess yielded a product (super cetane) in the diesel boiling range with a high Cetane value (55-90).

TL;DR: There is an urgent need to develop some easy technologies for formulation and mass production of fungi at a commercial scale for field application and some of these fungi may be used in integrated nematode management programmes despite some obstacles.

TL;DR: The extent to which each parameter tested was able to stimulate the formation of astaxanthin in the alga varied and the overall effectiveness of each treatment in promoting astaxAnthin formation in theAlga is discussed.

TL;DR: In this article, the authors studied the performance of biomethanation of banana peel and pineapple wastes at various HRTs and showed a higher rate of gas production at lower retention time.

TL;DR: In this article, the properties of products obtained in the cellulose decomposition process conducted in near-critical water were analyzed using HPLC, GPC and IR, and a reaction model consisting of the formation process of water solubles (WS) and the subsequent second decomposition process was proposed.

TL;DR: A model 6V92TA Detroit Diesel Corporation diesel engine (9.0 l) was tested using the Environmental Protection Agency (EPA) heavy-duty engine test cycle in an EPA certification test cell.

TL;DR: In this paper, the effects of ammonia fiber explosion (AFEX) treatment on the initial rates and 24 h hydrolysis yields for several crop residues and lignocellulosic materials using low enzyme levels (1−5 IU/g dry biomass).

TL;DR: In this article, the feasibility of thermophilic (55°C) anaerobic treatment of an alcohol distillery wastewater (cane molasses vinasse) was studied using a 140 l up-flow UASB reactor for a period of 430 days, where organic loading rates were applied up to 28 kg chemical oxygen demand m−3 d−1 by reducing hydraulic retention time at a fixed influent concentration of 10 g COD l−1.

TL;DR: A bench-scale unit for the development of an enzymatic process for the bioconversion of lignocellulosics to ethanol has been used to study the recycling of waste-water streams to minimize fresh-water requirements and reduce effluent streams as mentioned in this paper.

TL;DR: In this paper, the abilities of different species of seaweeds and their derivatives to remove a range of heavy metals from solution under standard laboratory conditions were determined, and the effect of the presence of more than one metal ion in solution was investigated in order to determine whether any competition effects might have affected metal-ion uptake.

TL;DR: In this paper, a review of published investigations regarding the economy of ethanol production from lignocellulosic material is presented, where the influence of plant capacity and overall product yield on the ethanol production cost is investigated, as well as variations in capital costs in different processes.

TL;DR: In this paper, the authors studied the bioconversion of solid paper-pulp mill sludges and primary sewage sludge for 40 days at a ratio of 3:1 dw:dw in containers with and without earthworms.

TL;DR: The dry matter content of poultry manures is suggested as a useful indicator of total fresh weight nutrient concentrations.

TL;DR: In this paper, the authors present an engineering framework for assigning economic consequences of the additional utilization of corn fiber in a wet-milling process, based on published compositional analyses of cellulose, starch, mono-saccharides, hemicellulose, protein and oil as distributed between the compartmentalized components of the corn kernel and published yield factors for hexose and pentose fermentations.

TL;DR: In this article, the emissions of harmful gases, malodorous compounds and greenhouse gases emitted during composting of swine feces under continuous aeration were studied using a laboratory-scale composting apparatus.

TL;DR: The solid residue of enzymatically hydrolysed SPW was found to be nearly as good a substrate as SPW, although the cellulose content was as low as 20% in this hydrolysis residue.

TL;DR: In this paper, color elimination by Aspergillus niger from wastewater from molasses alcoholic fermentation was studied, and the influences of the nutrient concentrations, initial pH and carbon source on this color elimination were analyzed.

TL;DR: In this paper, the effect of oxygen pressure and sodium carbonate addition on hemicellulose solubilization was investigated and it was shown that the two process parameters had little effect on the solubiliization of hemicella.
