Impact assessment of azulene and chromium on growth and metabolites of wheat and chilli cultivars under biosurfactant augmentation

Effects of Textile Effluent Fertilization on Germination, Growth and Metabolites of Chilli (Capsicum annum) Cultivars

“…Ajouri et al (2004) suggested that the minimum speed of germination is in control (without treatment) may be due to nutrient unavailability as well as nutrient deficiency in soil. The reason for the germination inhibition in the higher concentration of textile effluent can be explained as the toxic effect of heavy metals and persistent organic compound present in the composite textile effluent (Singh and Rathore, 2019). Delay index calculated in present experiment also showed delayed germination due to higher dose of textile effluent while vigor index showed vigorous characteristic of used seed with moderate dose of textile effluent.…”

Diagnostic hydrocarbon pollution in Veracruz beaches and airlift bioreactor how suggesting of remediation

“…En ambos meses los hidrocarburos encontrados fueron: eicosano, heneicosano, tetracosano, docosano benzo(a)pireno y azuleno. El azuleno es un isómero del naftaleno, el cual es considerado como tóxico por su naturaleza recalcitrante, además, bajo radiación ultravioleta puede producir rupturas en el ADN (Singh y Rathore, 2019). Sin embargo, es importante indicar que el azuleno solo fue encontrado en el mes de mayo.…”

Microbial biosurfactants: a review of recent environmental applications

“… 95 Evaluate the application of a produced biosurfactant on sand decontamination and an aqueous effluent containing heavy metals Biosurfactant extract Candida tropicalis Sand artificially contaminated with a metallic solution Zn Cu Pb Removal rate for Zn, Cu and Pb: 30, 80%, 15% by purified biosurfactant 60%, 55% and 10% by crude biosurfactant, respectively 5 Toxicity test Evaluate the growth of two species of crops, Triticum aestivum and Capsicum annum at different pollutants concentrations (10 ppm and 20ppm each) under biosurfactant stimulation Lipopeptide Brevibacillus brevis BAB-6437 Biosurfactant supplementation 3% (w/v) Cr Azulene Germination percentages of wheat crops and pepper crops: At 20 ppm Cr: 58%, 54.5% and At 20 ppm azulene: 58%, 59%, respectively. 2 Evaluate the effect of biosurfactant by larvicidal activity Anopheles culicifacies and toxicity test on onion bulbs Allium cepa germination Cyclic lipopeptide (CL) Bacillus tequilensis CH Larvicidal effect: 85, 100, 110, 130 and 145 ug mL −1 biosurfactant Toxic effects: 1ppm Cd + 0.1 mg mL −1 CL, 0.1 mg mL −1- CL CdCl 2 Larvicidal effect : 50% of mortality at biosurfactant concentration of 110 ug mL −1 Toxicity effect : at 1ppm Cd+0,1 mg mL −1 CL 52%, 8% and 36% with 0.1 mg mL −1 CL 76%, 44% and 20% of normal division, abnormal division, and non-dividing cells, respectively 97 Evaluate the biosurfactant effect on the growth of heavy metal accumulating plants Bidens pilosa . and Medicago sativa Sophorolipid (SL) - Growth effect: seedlings with 10 mL of SL at 0.5% Assisted phytoremediation: SL and Cd at 1.9 g pot −1 and 29.2 mgkg −1 , respectively Cd(NO 3 ) ...…”

“…In this case, plants contaminated with metals are treated, and the application of biosurfactants favors their development either in the germination phase or in correct cell division. [ 2 ], evaluated the effects of a lipopeptide produced by Brevibacillus brevis BAB-6437 on plants contaminated with two metal textile pollutants. Germination assays of wheat and pepper crops concluded that the application of biosurfactant increased the weight of leaves in plants contaminated with azulene and chromium at a concentration of 20 ppm.…”

“…Consequently, more effort is needed to solve environmental issues [ 1 ]. The most widely used energy resource is petroleum and its related products, whose transport and use often cause different forms of pollution, such as an increase in the biological and chemical oxygen demands in some soil or underground water environments [ 2 ]. Examples of this pollution are the spills of oil tanks in several parts of the world that have damaged millions of square kilometers of environmentally protected areas [ 3 , 4 ].…”
