摘要:
Our study navigated investigated the metal adsorption ability of bacterial Bacillus cereus strain HM-5 isolated from manganese ore. The effects of pH, initial metal ions concentration, biomass dose, contact time, and temperature on biosorption were studied. The results showed that the biosorption capacity of the B. cereus strain HM-5 for the metallic ions reached up to 98.9% for Mn at 600 mg/L initial metal ion concentration. The biosorptoin was most affected by pH and incubation temperature. Optimal pH and temperature were 6 and 35ºC, respectively. Optimal contact time was 5 d for biosorption by B. cereus strain HM-5. The surface chemical functional groups of B. cereus biomass identified by Fourier transform infrared (FTIR) were hydroxyl, alkyl, amide, phosphoryl, and phosphoric acid groups, which may be involved in the biosorption of heavy metals. SEM micrographs indicated that B. cereus HM-5 cells were irregular and cracked with the appearance of wrinkles and many flocs on the surface after Mn stress. The results showed that the selected bacteria had good application prospect in manganese-contaminated soil remediation. © 2018, HARD Publishing Company. All rights reserved.
