Application of Lentikats Biotechnology for removal of nitrates from ion-exchange brines: Implications for adaptation of encapsulated denitrifiers
Original language description
Denitrifying Bacterium Paracoccus denitrificans encapsulated in polyvinyl alcohol matrix (so called Lentikats Biocatalyst; LB) was applied for the removal of nitrates from simulated ion-exchange brines (12.14 g.L-1 Cl-, 1.35 g.L-1 SO42-, and 2.26 g.L-1 N-NO3-). The effect of brines dilution on the denitrification activity of fresh Lentikats Biocatalysts was tested simultaneously for four dilutions (100% = non-diluted, 80% = 4:1 brine:water, 60 and 40%) in four sequent repetitions per dilution without intermediate cultivation. In the first set, the denitrification of 100 and 80% brine was severely inhibited, while the denitrification activity in 60 and 40% brines was comparable to activity in non-inhibiting denitrification medium. The denitrification activity in 60 and 40% brines declined in later repetitions due to a lack of nutrients, while it increased in 80 and 100% brines before it declined as well. Such results are in contradiction to previous observations based on correlation ana
