Showing papers in "Bioresource Technology in 1995"

TL;DR: Biosurfactants are widely used for various purposes in industry, but for many years were mainly chemically synthesized as mentioned in this paper, and there are conflicting reports regarding their efficacy and the economics of both their production and application, and caution is frequently exercised with respect to their use because of possible subsequent microbial contamination of either underground oil reservoirs or products.

TL;DR: In this article, the potential of fungal biomass as sorbents is indicated by the available data, and more research and development of the fungal biosorption technology is recommended.

TL;DR: In this paper, the authors developed an anaerobic digestion process for Korean food wastes containing 15-30% total solids (TS) and measured the biochemical methane potentials of their components and mixture (mixed food waste, MFW) were measured.

TL;DR: In this article, a technical and economic comparison of three different processes for the production of fuel ethanol from pine is presented, and it is concluded that none of the processes can be eliminated as less economical than the others.

TL;DR: In the batch reactor system, denitrification was almost complete while the C/N ratio of each of the four different carbon sources (methanol, acetic acid, glucose, benzoic acid) was properly controlled.

TL;DR: The production of 2,3-butanediol by bacterial species continues to be of great interest because of its varied application as discussed by the authors, and two bacterial species, Bacillus polymyxa and Klebsiella pneumoniae have demonstrated potential for butanediol fermentation on a commercial scale.

TL;DR: A review of progress in the treatment of wastewater from slaughterhouses is presented in this article, where significant progress in issues such as nutrient removal and high-rate anaerobic treatment are highlighted.

TL;DR: Banana pith (Musacea zingiberales) was evaluated for its ability to sorb metal ions from electroplating waste and synthetic solutions under both batch-and continuous-flow conditions as discussed by the authors.

TL;DR: In this article, the effects of temperature, air to liquid flow ratio and pH were investigated using wastewaters with a range of solids concentrations and pH values, and the results showed that at a pH of 9·5 and 10·5, ammonia removal efficiency was directly dependent upon the air and liquid influent temperatures.

TL;DR: In this article, the lignin peroxidase (LiP) activity was monitored in five white-rot fungi cultivated on nitrogen (N)-limited glucose-BIII medium and were compared with the activities obtained in media supplemented with 56 m m peptone.

TL;DR: In this paper, the potential of the biomass of non-living, dried, roots of water hyacinth (Eichhornia crassipes) to remove two basic dyes, methylene blue and Victoria blue, from aqueous solutions were conducted.

TL;DR: In this paper, dilute (0·06 and 0·5%) sulfuric acid at 100, 120 and 140°C has been investigated for the solubilization and depolymerization of carbohydrates in oranges.

TL;DR: In this paper, the authors compared the performance of empty-fruit-bunches with either goat dung, cow dung or chicken manure and found that mesophilic and thermophilic bacteria showed consistent activity throughout the process, whereas fungal activity was completely suppressed during peak heating phase.

TL;DR: In this article, the effects of different application rates of organic and inorganic fertilizers on soil physical properties and maize production in a severely degraded Ultisol in southern Nigeria were studied for two growing seasons.

TL;DR: In this paper, the anaerobic treatment of wastewaters from the seafood processing industry was studied in a 15 m3 industrial pilot-plant, where the adaptation of the biomass to the salinity and the antagonistic effects on sodium toxicity caused by the presence of other ions made it possible to operate at these high sodium concentrations.

TL;DR: A reduction in production time with high volumetric productivity and inexpensive raw materials make sophorolipid competitive against surfactants used in the food and cosmetics industries.

TL;DR: In this article, the degradation pattern of Sugarcane bagasse, a complex substrate, when differentiated into four fractions of particle sizes with a view to enhancing its nutritive value as animal feed rather than production of fungal protein for human consumption, showed a varying pattern of degradation by white-rot fungi.

TL;DR: In this paper, the use of peat for the continuous adsorption of hexavalent chromium in columns was examined and two flow-rates were used at each pH value.

TL;DR: In this paper, the results of a wide experimental campaign carried out on an IDI engine and aimed at evaluating the overall performance, the emissions and the combustion trends observed with the new fuel.

TL;DR: It was shown that competition between hydrogen-producing and hydrogen-utilising acidogenic bacteria for glucose causes a hydrogen partial pressure decrease at a decrease of feed flow rate.

TL;DR: In this paper, a cellulosic byproduct of the soymilk and tofu (soypaneer) industry was used for the production of citric acid by solid-state fermentation using a cellulolytic Aspergillus terreus and citric-acid-producing Asperger niger.

TL;DR: In this paper, steam pretreatment of willow with the addition of SO2 or H2SO4 was studied, the aim being to recover both the cellulose and the hemicellulose fr actions.

TL;DR: A greenhouse experiment was conducted to evaluate the effect of fly-ash application on dry-matter yield and nutrient composition of 60 day-old rice and wheat plants and on pH and available nutrient status of soils as discussed by the authors.

TL;DR: Fermented fish-silage codried with protein feedstuffs is a suitable protein supplement, which can provide up to 50% of dietary protein without affecting feed efficiency, fish growth or health.

TL;DR: The activity and stability of the enzymes suggest a potential role for enzyme cocktails from compost extracts in the biological upgrading of grass lignocelluloses to animal fodder.

TL;DR: In this paper, a method for wood esterification using fatty acid chlorides in the absence of organic solvents is proposed, where a nitrogen stream was used to carry off the hydrogen chloride formed during synthesis and to displace the equilibrium of the reaction.

TL;DR: In this article, a study was conducted using polyethylene glycol (PEG) as an additive to enhance enzyme performance for the treatment of synthetic wastewaters containing a range of phenol concentrations between 0·5 and 16 millimolar at neutral pH.

TL;DR: Results show that both hydrolysates can be converted into xylitol with satisfactory yields and productivities.

TL;DR: In this paper, a two-stage, acid-catalyzed process was used to fraction wheat straw into cellulosic fibres, hemicellulose sugars and solid lignin oligomers.
