BACKGROUND: The use of microorganisms in remediating environmental contaminants such as crude oil sludge has become a promising technique owing to its economy and the fact it is environmentally friendly. Polycyclic aromatic hydrocarbons (PAHs), as the major components of oil sludge, are hydrophobic and recalcitrant. An important way of enhancing the rate of PAH desorption is to compost crude oil sludge by incorporating commercial surfactants, thereby making them available for microbial degradation...

The biosurfactant production by Bacillus licheniformis W16 and evaluation of biosurfactant based enhanced oil recovery (EOR) using core-flood under reservoir conditions were investigated. Previously reported nine different production media were screened for biosurfactant production, and two were further optimized with different carbon sources (glucose, sucrose, starch, cane molasses, or date molasses), as well as the strain was screened for biosurfactant production during the growth in different media. The biosurfactant reduced the surface tension and interfacial tension to 24...

In many higher plants, seed oil accumulation is precisely controlled by intricate multi-level regulatory networks, among which transcriptional regulation mainly influences oil biosynthesis. In Arabidopsis, the master positive transcription factors, WRINKLED1 (WRI1) and LEAFY COTYLEDON1-LIKE (L1L), are important for seed oil accumulation. We found that an R2R3-MYB transcription factor, MYB89, was predominantly expressed in developing seeds during maturation. Oil and major fatty acid biosynthesis in seeds was significantly promoted by myb89-1 mutation and MYB89 knockdown; MYB89 was thus an important repressor during seed oil accumulation...

Influence of the immunization procedure on the specificity of the produced antibodies towards different conformations of the antigen was investigated. It was demonstrated that intravenous immunization of a rabbit with an adjuvant-free solution of recombinant sperm-specific glyceraldehyde-3-phosphate dehydrogenase (dN-GAPDS) resulted in production of antibodies recognizing only native conformation of dN-GAPDS and exhibiting no cross-reaction with somatic isoenzyme of glyceraldehyde-3-phosphate dehydrogenase...

Naphthenic acids (NAs), a class of structurally diverse carboxylic acids with often complex ring structures and large aliphatic tail groups, are important by-products of many petrochemical processes including the oil sands mining activity of Northern Alberta. While it is evident that NAs have both acute and chronic harmful effects on many organisms, many aspects of their toxicity remain to be clarified. Particularly, while substantive data sets have been collected on NA toxicity in aquatic prokaryote and vertebrate model systems, to date, nothing is known about the toxic effects of these compounds on the embryonic development of aquatic invertebrate taxa, including freshwater mollusks...

Microorganisms are the main contributing factor responsible for organic matter degradation during composting. In this research, the 454-pyrosequencing of the 16S rRNA gene was used to elucidate evolution of bacterial diversity during mesophilic, thermophilic and maturation composting stages of the two-phase olive mill waste ("alperujo"), the main by-product of the Spanish olive oil industry. Two similar piles were performance composting AL with sheep manure as bulking agent. Actinobacteria, Bacteriodetes, Firmicutes and Proteobacteria were the main phyla found in genomic libraries from each composting phase...

This study aimed to investigate the effect of olive oil-rich diet on omentin and adiponectin concentrations. This cross-over randomized trial included 17 overweight women. Participants were assigned to consume either a usual (16% saturated fatty acids [SFA] and 8% monounsaturated fatty acid [MUFA]) or an olive oil-rich diet (16% MUFA and 8% SFA) for 6 weeks crossing over after a 2-week washout period. There was no significant difference in the changes of omentin between two dietary interventions. However, in the adjusted model for polyunsaturated fatty acids and fat mass, usual diet tended to decrease omentin levels whilst olive oil-rich diet tended to increase (-56...

Bacterial interactions with surfaces are at the heart of many infection-related problems in healthcare. In this work, the interactions of clinically relevant bacteria with immobilized liquid (IL) layers on oil-infused polymers are investigated. Although oil-infused polymers reduce bacterial adhesion in all cases, complex interactions of the bacteria and liquid layer under orbital flow conditions are uncovered. The number of adherent Escherichia coli cells over multiple removal cycles increases in flow compared to static growth conditions, likely due to a disruption of the liquid layer continuity...

Feeds contribute highly to environmental impacts of livestock products. Therefore, formulating low-impact feeds requires data on environmental impacts of feed ingredients with consistent perimeters and methodology for life cycle assessment (LCA). We created the ECOALIM dataset of life cycle inventories (LCIs) and associated impacts of feed ingredients used in animal production in France. It provides several perimeters for LCIs (field gate, storage agency gate, plant gate and harbour gate) with homogeneously collected data from French R&D institutes covering the 2005-2012 period...
