“…Mass transfer was expected to be an important rate-limiting factor in the overall process. Rates of aerobic S 0 oxidation soils is known to be dependent on surface area (Germida and Janzen, 1993;Lee et al, 1988;Sholeh et al, 1997). Increasing S 0 concentration would provide an increased surface area for colonization and dissolution, thus, it is expected that the greater S 0 concentrations would support more rapid kinetics.…”

Perchlorate (ClO(4)(-)) contamination of ground and surface water has been recently recognized as a widespread environmental problem. Biological methods offer promising perspectives of perchlorate remediation. Facultative anaerobic bacteria couple the oxidation of organic and inorganic electron-donating substrates to the reduction of perchlorate as a terminal electron acceptor, converting it completely to the benign end-product, chloride. Insoluble inorganic substrates are of interest for low maintenance bioreactor or permeable reactive barrier systems because they can provide a long-term supply of electron donor without generating organic residuals. The main objective of this research was to investigate the feasibility of utilizing elemental sulfur (S(0)) as an insoluble electron donor for the biological reduction of perchlorate. A chemolithotrophic enrichment culture derived from aerobic activated sludge was obtained which effectively coupled the oxidation of elemental sulfur to sulfate with the reduction of perchlorate to chloride and gained energy from the process for cell growth. The enrichment culture grew at a rate of 0.41 or 0.81 1/d in the absence and presence of added organic carbon for cell growth, respectively. The enrichment culture was also shown to carry out sulfur disproportionation to a limited extent as evidenced by the formation of sulfide and sulfate in the absence of added electron acceptor. When nitrate and perchlorate were added together, the two electron acceptors were removed simultaneously after an initial partial decrease in the nitrate concentration.

“…2c and C). There are a number of reasons for this result in high plant uptake and accumulation of these heavy metals; however, the main reason is most probably that the increase of solubility of Zn and Cd leads to an improvement in metal bioavailability with a decrease of soil pH by application of S. There are certain groups of acidophilic soil bacteria in the soil, predominantly the genus Thiobacillus, that can oxidize S and change it to SO 4 2 À when soil pH has decreased (Lee et al, 1988;Tichý et al, 1997;Kayser et al, 2000). McLaughlin et al (1998) reported that increasing SO 4 2 À in soil could increase shoot Cd concentration, in the present experiment, the increasing SO 4 2 À in soil (data were not given) may be another cause that increased the shoot Cd content.…”

“…One important fact is the oxidation of S by certain groups of acidophilic bacteria, notably Thiobacillus spp. in the soil (Lee et al, 1988;Seidel et al, 1998;Tichý et al, 1997;Kayser et al, 2000). Tichý et al (1997) reported that 156 mmol of different types of elemental sulphur per kilogram of soil were added to a gleyic cambisol with an initial soil pH between 5 and 5.5, the soil pH decreased to 3.3 within 80 days.…”

A pot experiment was conducted to study the influence of elemental sulphur (S) on solubility of soil Pb, Zn and Cd and uptake by maize (Zea mays L.). Two rates of elemental sulphur (S) applied at 0 (S 0 ) and 200 (S 200 À 1 soil, respectively. The result showed that with S application at 200 mmol S kg À 1 , soil pH decreased about 0.3 unit and the solubility of the Zn and Cd was significantly increased, but the solubility of Pb had no significant influence. The concentration of Pb, Zn and Cd in maize shoots and roots were increased with increasing rates of heavy metals. However, the concentration of Zn and Cd in shoots and roots were higher with application of S rather than without S but no significant difference was found for Pb. The highest concentration of Zn in the shoots was 2.3 times higher with application of S rather than without at the same rate of Zn, 200 mg kg. Plant biomass was also significantly affected by the application of S and of heavy metals. With heavy metal addition, the shoot and root biomass were decreased with the rates of those of heavy metals increased either with or without application of S. However, the shoot biomass was significantly decreased with S application at the same rate of heavy metals except that with Zn addition. The removal of Cd and Pb by maize uptake and accumulation with application of S had no significant increase compared to that without, but the removal Zn by maize uptake from the soil increased by application of S, 90.9 Ag plant À 1 contrast to 25.7 Ag plant À 1 at Zn 200 within a growth period of only 40 days.

“…The soil acidifying effect of S 0 may be explained by the activities of certain groups of acidophilic soil bacteria, particularly the genus Thiobacillus, which can metabolize S 0 in the presence of O 2 and generate H þ and SO 2À 4 , leading to soil acidification. [11][12][13][14] …”
