Showing papers in "International Biodeterioration & Biodegradation in 2001"

TL;DR: In this paper, the authors used the halo zone test to evaluate the antimicrobial properties of polymeric polymers with phenol and benzoic acid as pendant groups, and the results showed that polymers exhibited low antimicrobial activity when compounded with low molecular weight antimicrobial agents due to the extremely slow diffusion.

TL;DR: The determination of a satisfactory condition for the use of this type of photobioreactor in tropical climates and the study of its performance under various dilutions were the main objectives of this work.

TL;DR: Common fungal isolates from refineries and distribution systems grew equally well in laboratory diesel/water systems with or without a chemical additive mixture, showing that this package of compounds neither promoted nor retarded fungal growth.

TL;DR: In this article, a mixed culture of iron oxidizing bacteria, originally isolated from rust deposits of a clogged carbon steel heat exchanger was used to study the corrosion mechanism of 1020 AISI carbon steel in iron bacteria contaminated water.

TL;DR: Results suggested that cellulases induced in the presence of each substrate were able to hydrolyze more effectively, if substrate concentration was similar to that used in the induction of enzymes.

TL;DR: Extracellular xylanase production by selected isolates of the current study was characterized during their growth on xylan as a sole carbon source on solid medium and the results revealed that 93.3% of the isolates tested could degrade xylan and the highest activity against xylan was showed by members of Aspergillus, Fusarium, Penicillium and Trichoderma.

TL;DR: The microbial diversity of in-use emulsifiable oil metal- working fluids is investigated to develop strategies to improve metal-working fluid formulation and longevity, and to improve microbial exploitation for biological disposal routes using bioreactors.

TL;DR: In this article, the susceptibility to bioremediation of the hydrocarbons contained in a waste from crude oil extraction was examined, and the substrate preferences of the natural population towards various fractions of the crude oil were determined by both the length of the lag phase and the slope of the exponential growth in a mineral salt-base medium containing either of the different hydrocarbon fractions as the sole source of carbon.

TL;DR: Findings suggest that C. aquaetextoris might metabolise pNP via terminal oxidation of the alkyl chain, followed by a β-oxidation pathway, and a novel metabolic route for the microbial degradation of 4-(1-nonyl)phenol, at least in certain yeasts is proposed.

TL;DR: Analysis of the predicted amino acid sequences for the PueB, PueA, and other polyurethanase enzymes and similar lipase enzymes suggested that they have evolved from lipases, and are not derived from a single source.

TL;DR: In this article, the effect of remediation processes, namely oxalic acid (OA) extraction and Bacillus licheniformis fermentation, on leaching of copper, chromium, and arsenic from particleboard made from remediated wood particles and also investigates decay resistance of the particleboard.

TL;DR: The problem of antibiotic resistance development is reviewed and the potential clinical implications of inappropriate biocide use are considered, contributing to the evolution and persistence of drug-resistance within microbial communities and could adversely affect the clinicians’ therapeutic arsenal.

TL;DR: In this paper, a biocorrosion mechanism by which the excretion of acidic products can promote Fe 2+ availability for sulfate-reducing bacterium (SRB) was proposed.

TL;DR: The literature concerning site characteristics that impact the biodegradation of historic submerged wood, and the current research on archeological wood removed from waterlogged environments are reviewed.

TL;DR: Laboratory experiments demonstrated that fungal degradation of lubricating grease produced organic acids and localized corrosion of carbon steel cables in polyvinyl chloride sheaths and there was a spatial relationship between fungal hyphae and corrosion.

TL;DR: In this article, the decay types identified were soft rot, erosion and tunnelling bacteria, which occurred in samples buried under near anaerobic conditions, while soft rot decay was evident for samples buried in less anaerobitic conditions and high organic matter content of the soil.

TL;DR: In this article, the application of a partial dehydration conventional embedding protocol for ultrathin-section transmission electron microscopy preserved the hydrocarbon degrading bacteria-surfactant-oil interface and showed that less than 1% surfactant is required to emulsify waste hydrocarbon during or to promote biodegradation.

TL;DR: In this paper, the first-order reaction kinetics of E. coli and Staphylococcus aureus death in CaO powder slurps was assumed to follow first order reaction kinetic.

TL;DR: There is a group of characteristic species on granite monuments whatever the environmental conditions are, and a large number of species were identified on each coastal church that brought some important data to the relationship between salts weathering and the protective action of lichens.

TL;DR: In this article, the primary cause appears to be the production of a volatile phosphorous compound by SRB which reacts with iron to form a black precipitate in the medium, the highly reactive compound is produced from an organic compound, inositol hexaphosphate, the major source of phosphorous in plants.

TL;DR: In this paper, field-collected samples taken from palo podrido were sorted visually into three groups representing early, and two stages of advanced delignification (termed as EDS, ADS1 and ADS2, respectively).

TL;DR: The results suggest that protection of susceptible strains by resistant organisms may occur under field conditions because of the varied resistance levels among isolates from a single system to FA.

TL;DR: In this paper, an array of microcosms containing California Air Resources Board (CARB)-compliant, oxygenated 87-octane gasoline over nutrient-amended water was monitored over a 7-month period.
