Table 1: Known factors in processing of microbes in industrial side streams affecting biosorption capacity. EC = Extracellular Entzymes, IC = Intracellular Entzymes.
Process phase Factor Effect on biosorption
Effect on cell wall Effect on biosorption
Ethanol fermentation High ethanol concentration Lower specific surface area and reduced concentration of mannans in the cell wall [31] Negative
Increased chitin concentration [24] Positive
Denaturation of soluble cell wall proteins [35,36] Positive
Enzyme production Phosphate limitation Lower amount of teichoic acids in Bacillus [45] Negative
Separation (filtration) Shear forces Disintegration and leaking of cell wall polysaccharides [47] Negative
Thermal disruption High temperature Denaturation of soluble cell wall proteins [35,36] Positive
Mechanical disruption Shear forces Disintegration and leaking of cell wall polysaccharides [47] Negative
