ISOLA FED AND SURVEYED REDUCE HYDROGEN SULFITE (H2S) ABILLITY OF SULFUR-OXIDIZFNG BACTERIA (SOB) IN THE WATER OF NHIEU LOC - THI NGHE CANAL

Abstract

8 strains of Sulfur oxidizing bacteria (SOB) were isolated and tested in order to removehydrogen sulfide (H2S) from Nhieu Loc - Thi Nghe canal in the aerotank pilot scale. Thedesulphurization ability of the strains N3.4; N l l . l ; NlO.l; N6.1;N3.6; N3.1; N6.2; N3.3 weredecreased (99.29%; 83.05%; 81.25%; 80.00%; 73.52%; 68.18%; 41.91%; 25.00%) respectively
