BIOREMEDIATION OF XENOBIOTICS: USE OF DEAD FUNGAL BIOMASS AS BIOSORBENT

Myxococcus xanthus biomass as biosorbent for lead.

This paper deals with lead biosorption by Myxococcus xanthus biomass in which dry biomass, accumulating up to 1.28 mmol of lead g(-1), is demonstrated to be a more efficient biosorbent than wet biomass. Dry biomass biosorption was found to be very rapid, reaching equilibrium after 5-10 min. Culture age, the initial lead concentration and pH affected this process, but temperature did not. Furthe...

Effect of Hexavalent Chromium and Aluminium in Fresh Water Fish Ictalurus Punctatus and Bioremediation by Using Dead Fungal Biomass

Fish serum may reflect status of many biochemical processes in the metabolism. Heavy metals may alter serum biochemical parameters in fishes. In this study, the effect of Cr(VI) and Al(III) in fresh water fish I.Punctatus and neutralize these metals by using dead fungal biomass. Activity of serum enzymes AST, ALT, ALP, CPK, LDH and α – amylase in aluminium and chromium exposed fish. The above s...

Bioremediation of Waters Contaminated with Heavy Metals Using Moringa oleifera Seeds as Biosorbent

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

biosorption of cr (vi) ions from aqueous solution by the dead fungal biomass aspergillus niger

chromium is one of the major causes of environmental pollution. to remove heavy metal ions from water, microorganisms can be used. in this study, dead fungal biomass of aspergillus niger is used. the biomass was boiled in 0.5 n naoh solutions to increase the metal removal capacity of a.niger and was applied when the ph of wash solution was in the normal range. the optimum adsorption ph value ob...
