The fungal genus Exophiala comprises both pathogen species, which cause severe infections in humans, and environmental species, which are able to degrade alkylbenzene compounds. The draft genome sequence of Exophiala mesophila presented here is the first genome assembly of an alkylbenzene-degrading organism belonging to the genus Exophiala.
In this study, the elucidation of the toxicity mechanism was undertaken regarding the IC(50) of the oxygen uptake rate (OUR) with relevance to the biosorption as a toxicity evaluation of chemical substances for activated sludge (AS). At the IC(50) of<100 mg/l, malachite green (MG) and crystal violet (CV) were confirmed in the group showing relatively strong OUR inhibition. These dyes were marke...
Composting is an important waste management strategy, providing economical and environment-friendly approach to sanitizing stabilizing biosolids for land soil amendment. However, the resulting product can contain a large number of organic pollutants that may have adverse effects on ecosystem. This paper presents occurrence eight widely used (four linear alkylbenzene sulfonates (LAS C10-C13), no...
Background and Objective: Nowadays linear alkyl benzene sulfanate (LAS) is widely used in the production of various detergents. The purpose of this study was to assess the health and ecological hazards of this pollutant on target organisms such as fish and daphnia in the Doroodzan Dam water. Materials and Methods: According to the research objective and given existing restrictions, 21 water sa...
The adsorption of the lactonic (LS) and acidic (AS) forms of sophorolipid and their mixtures with the anionic surfactant sodium dodecyl benzene sulfonate (LAS) has been measured at the air/water interface by neutron reflectivity, NR. The AS and LS sophorolipids adsorb with Langmuir-like adsorption isotherms. The more hydrophobic LS is more surface active than the AS, with a lower critical micel...
