Biodegradation of textile dye Rhodamine-B by Brevundimonas diminuta and screening of their breakdown metabolites.

The carcinogenic Rhodamine-B dye is recalcitrant which could cause serious hazards to human beings. Degradation with the application of unique bacterial strain is a sustainable technique. The bioremediation technique showed great potential to degrade a variety of recalcitrant pollutants like dyes.

A review on new aspects of lipopeptide biosurfactant: Types, production, properties and its application in the bioremediation process.

Nowadays, the worldwide search regarding renewable products from natural resources is increasing due to the toxicity of chemical counterparts. Biosurfactants are surface-active compounds that contain several physiological functions that are used in industries like food, pharmaceutical, petroleum and agriculture. Microbial lipopeptides have gained more attention among the researchers for their low toxicity, efficient action and good biodegradability when compared with other surfactants.

Investigation of magnetic silica nanocomposite immobilized Pseudomonas fluorescens as a biosorbent for the effective sequestration of Rhodamine B from aqueous systems.

In the current research work, a novel eco-friendly FeO@SiO nanocomposite immobilized with Pseudomonas fluorescens biomass in calcium alginate beads (MSAB) was used as biosorbent for the elimination of hazardous Rhodamine B dye from aqueous system. The FTIR, XRD and SEM results showed that the MSAB possessed excellent surface properties for the effective sequestration of Rhodamine B. The batch adsorption results concluded that the adsorption of Rhodamine B using MSAB is highly influenced by the parameters such as pH, adsorbent dosage, initial dye concentration and contact time.
