Aggregation properties of p- and n-functionalized calix[4]resorcine in water/oil emulsion in the presence of sulfate reducing desulfobacter bacteria

Abstract

Abstract This paper presents a comparative study of the aggregation properties of P- and N-functionalized calix[4] resorcines in “water/oil emulsion + Desulfobacter culture”. It has been shown that both compounds under study displayed aggregation properties in low concentration range. Nevertheless, their structural features affect the aggregation process. Moreover, the beginning of aggregation of N-functionalized calix[4]resorcine with petroleum hydrocarbons molecules and microorganism cells shifted to lower concentration zones than the one of P-functionalized calix[4]resorcine. However, P-functionalized calix[4]resorcine was characterized by a wider interval at which the structuring of the water/oil emulsion is observed.
