HS-Protein Associates in the Aqueous/Oil System: Composition and Colloidal Properties

Fulvic acids separated from Suwannee River behavior in the aqueous-xylene system: influence of ionic strength and interaction with proteins

“…It was found that both proteins reduce adsorption of SRFA, while adsorption of albumin in presence of SRFA was close to the adsorption of free protein, and it depended on the SRFA concentration in the case of lysozyme: at low SRFA concentrations it was lower than for free protein and exceeds this value for high SRFA concentration. Moreover, when SRFA was mixed with lysozyme the formation of insoluble complexes was observed as it was shown previously for coal humic acids [2]. Using tritium labeled materials we have determined the composition of the complex for different concentrations of SRFA.…”
