“…After 96 hours, the removal efficiency of iron and manganese decreased respectively. Similar results were also produced by Kanamarlapudi & Muddada in 2020 who indicated that metal ion accumulation can cause saturated microbes that leads to metal ion desorption inside the solution (Kanamarlapudi, 2020).…”

Mine acid drainage (MAD) is a primary environmental problem caused by mining activity. The main characteristics of MAD are extremely low pH level (1.5-4.0), as well as content of sulfate and a number of heavy metals and metalloids that can destroy vegetation, accelerate erotion, and disrupt land ecosystem balance. The objective of this research was to process MAD by improving pH level and lowering iron and manganese content in MAD by Lactobacillus casei and Dekkera bruxellensis mixed culture. MAD Neutralization test was conducted on SMSs media with MAD concentration variations of 10, 15, 20 and 25 (%;v/v), and contact time variations of 48, 96, 144, and 192 (hours). The MAD neutralization test by Lactobacillus casei and Dekkera bruxellensis mixed culture occurred best at 10% concentration (v/v) with contact time of 96 hours. The pH improvement reached up to 6.20 with iron metal efficiency removal at 32.47% and manganese metal up to 24.94%. MAD neutralization test revealed that the best contact time variation is at 96 hours. At this contact time, the pH level was increased to 6.17 with iron metal removal efficiency at 31.17% and manganese metal removal at 25.43%.

Biosorbents have been extensively studied for heavy metal adsorption due to their advantages of low cost and high efficiency. In the study, the living and non-living biomass of Cupriavidus necator GX_5 previously isolated were evaluated for their adsorption capacity and/or removal efficiency for Cd (II) through batch experiments, SEM and FT-IR investigations. The maximum removal efficiency rates for the live and dead biomass were 60.51% and 78.53%, respectively, at an optimum pH of 6, a dosage of 1 g/L and an initial Cd (II) concentration of 5 mg/L. The pseudo-second-order kinetic model was more suitable for fitting the experimental data, indicating that the rate-limiting step might be chemisorption. The Freundlich isotherm model fit better than the Langmuir isotherm model, implying that the adsorption process of both biosorbents was heterogeneous. FT-IR observation reflected that various functional groups were involved in Cd (II) adsorption: –OH, –NH, C=O, C–O and C–C groups for the living biomass and –OH, –NH, C–H, C = O, C–N and N–H groups for the dead biomass. Our results imply that non-living biosorbents have a higher capacity and stronger strength for absorbing Cd (II) than living biomass. Therefore, we suggest that dead GX_5 is a promising adsorbent and can be used in Cd (II)-contaminated environments.
