Biosorption of Cadmium by Fucus spiralis [PDF]
Environmental Chemistry, 2004 Environmental Context. Conventional processes for the removal of heavy metals from wastewaters generally involves chemical precipitation of metals (changing the pH) followed by a period to allow the metal precipitates to settle and be separated. These processes are inefficient when the metals are at a low concentration and still demand handling and ...

Biosorption of Hexavalent Chromium from Aqueous Medium with Opuntia Biomass [PDF]
The Scientific World Journal, 2014 The biosorption of hexavalent chromium from aqueous solutions by Opuntia cladodes and ectodermis from cactus fruits was investigated. Both types of biomass are considered low-cost, natural, and ecofriendly biosorbents.

First-Time Demonstration of a Two-Step Mechanism for Azo Dye Removal by Bacillus proteolyticus Using Molecular Docking and FT-IR. [PDF]
Water Environ ResBacillus proteolyticus OA7, isolated from textile wastewater, efficiently removed Acid Red 88 (69.74%) and Acid Blue 193 (41.01%) through substrate‐dependent mechanisms. Acid Red 88 removal involved both biosorption and biodegradation, whereas Acid Blue 193 was mainly biosorbed. FT‐IR revealed functional group changes associated with EPS, proteins, and

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers. [PDF]
New PhytolHabit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Copper biosorption by Auricularia polytricha [PDF]
Letters in Applied Microbiology, 2003 The objective of the present study was to determine the optimum conditions for copper (Cu) biosorption by Auricularia polytricha mycelium in view of its immobilization in polyvinyl alcohol (PVA).The adsorption of Cu(II) onto A. polytricha was studied in batch with respect to initial pH, temperature, adsorption time, initial metal ion and biomass ...
