TL;DR: In this paper, a review discusses different mechanisms by which microbes induce or inhibit corrosion in metals and the roles of these factors are also emphasized, as the corrosive or inhibiting behaviors of microorganisms vary considerably depending on environmental factors.

TL;DR: This study reports the removal of 30 diverse trace organic contaminants (TrOC) by live, intracellular enzyme-inhibited and chemically inactivated whole-cell preparations and the fungal extracellular enzyme extract from Trametes versicolor (ATCC 7731).

TL;DR: The most appropriate strategy for bioremediation of Cr(VI) and lindane co-contaminated soils would be the inoculation with Streptomyces sp.

TL;DR: In this article, a fungal bioremediation method was developed for soils heavily contaminated with persistent organic compounds, such as polyaromatic hydrocarbons (PAHs), which was performed at both laboratory and field scales.

TL;DR: Analysis of the ability of Pseudomonas putida to degrade aflatoxin B 1 showed that AFB 1 was bio-transformed to structurally different compounds, with the modified furan and lactone ring on the AFB 1 molecule.

TL;DR: In this article, ureolytic Exiguobacterium undae was employed for immobilization of cadmium in contaminated soil at low temperature (10°C) and the sequential extraction test revealed conversion of more than 90% of the tested soil from the soluble-exchangeable fraction to carbonate-bound fraction in 14 days of treatment.

TL;DR: In this paper, the authors used aqueous filtrate of de-oiled karanja and jatropha (Jatropha curcas) cakes left after extracting oil for preparing biodiesel to enhance the activity of eucalyptus oil as a pesticide by making a nanoemulsion for the control of Tribolium castaneum, a secondary pest of stored grains.

TL;DR: In this paper, a response surface methodology (RSM) based on a factorial design was performed to investigate and optimize the effects of the microbial consortia application rate and amount of mature compost amendment on the TPH removal.

TL;DR: In this paper, HPLC and GC-MS analysis was performed on three Streptomyces spp. isolates AB1, AH4, and AM2 from surface soils at Mitidja plain (North of Algeria).

TL;DR: In this paper, the effect of an organic loading rate (OLR) and a hydraulic retention time (HRT) was evaluated by comparing the single-stage and two-stage anaerobic digestion processes.

TL;DR: In this paper, the main MDWW colorants are polyphenols, melanoidin, alkaline degradation products of hexoses, and caramels whose formation, concentration and antimicrobial effects are summarized in this review.

TL;DR: Utilization of M. oleifera derivatives as bio-coagulant provides several advantages such as lower impact on the environment, lower cost formicroalgae harvesting, allow rapid microalgae culture expansion and as chemical-free green technology.

TL;DR: The chemical characterization of this EO through GC/GC–MS analysis depicted 13 compounds comprising 97.09% of the EO, carvone being the major component (59.6%) and the phytotoxicity assay showed 100% germination of EO-treated chickpea seeds.

TL;DR: This study aimed to compare the growth and proximate composition of Nannochloropsis sp.

TL;DR: In this article, the five most popular chemical mitigation strategies that were previously mentioned have been investigated and discussed and discussed The article is broken down into three main discussions Firstly the sewer transformation processes and factors affecting the hydrogen sulphide generation and emission are highlighted Secondly, comparisons and differences between each selected chemical mitigation strategy as well as its application covered Finally, the review of the chemical efficiency and cost is conducted by comparing two case studies in controlling the formation of dissolved sulphide.

TL;DR: In this article, a set of experiments has been carried out testing M-doped TiO2 compounds for their efficiency as photocatalysts, for the chromatic changes induced by their application on stone surfaces and for their antibacterial activity against selected Gram positive and Gram negative bacteria.
