The surface tension was measured in cell-free culture supernatants. Interestingly, the surface tension decreased with time in all cultures (Figures 1–3).However, the extent of surface tension reduction was different depending on the utilized sulfur source (Table 2).The surface tension of the DBT culture was significantly different from that of the DBT-sulfone and the MgSO 4 cultures (p < 0.05).

Flue Gas Desulfurization - an overview | ScienceDirect Topics

Several wet ,flue gas desulfurization, (FGD) processes are based on the absorption of sulfur dioxide in caustic suspension or absorption liquor. The dissolved sulfur dioxide, which we will refer to as S (IV), is neutralized by the additive, commonly lime or limestone [1]. In aqueous phase several species of S (IV), hydrated sulfur dioxide, bisulfite ...

A dibenzothiophene (DBT)-desulfurizing bacterial strain was isolated and identified as Gordona strain CYKS1. Strain CYKS1 was found to transform DBT to 2-hydroxybiphenyl via the 4S pathway and to be able to also use organic sulfur compounds other than DBT as a sole sulfur source. Its ,desulfurization, activity was susceptible to sulfate repression. Active resting cells for ,desulfurization, could ...
