“…It was observed that a pure culture of SRB can tolerate 0.3-0.8 mM of Cu (Booth and Mercer 1963), similar to what was observed by Saleh et al (1964), who also reported that SRB can tolerate around 1.5 mM of Zn. The use of 0.35 mM of Cd and 0.4 mM of Pb induced 50 % inhibition in a SRB pure culture (Loka Bharathi et al 1990), while Desulfovibrio desulfuricans was reported to be sensitive to concentrations of Ni and Zn above 0.17 and 0.20 mM, respectively (Poulson et al 1997).…”

Anaerobic digestion (AD) is a well-established technology used for the treatment of wastes and wastewaters with high organic content. During AD organic matter is converted stepwise to methanecontaining biogas-a renewable energy carrier. Methane production occurs in the last AD step and relies on methanogens, which are rather sensitive to some contaminants commonly found in wastewaters (e.g. heavy metals), or easily outcompeted by other groups of microorganisms (e.g. sulphate reducing bacteria, SRB). This review gives an overview of previous research and pilot-scale studies that shed some light on the effects of sulphate and heavy metals on methanogenesis. Despite the numerous studies on this subject, comparison is not always possible due to differences in the experimental conditions used and parameters explained. An overview of the possible benefits of methanogens and SRB co-habitation is also covered. Small amounts of sulphide produced by SRB can precipitate with metals, neutralising the negative effects of sulphide accumulation and free heavy metals on methanogenesis. Knowledge on how to untangle and balance sulphate reduction and methanogenesis is crucial to take advantage of the potential for the utilisation of biogenic sulphide as a metal detoxification agent with minimal loss in methane production in anaerobic digesters.

SUMMARYDesulfovibrio gigas and several strains of D. desulfwicans grew by fumarate dismutation in a sulphate-free medium. Two strains of D. desulfuricans grown in a chemically defined medium formed succinate, malate and acetate during fumarate dismutation. Sulphate reduction by these strains, though not by D. gigas, was almost completely inhibited in presence of fumarate as alternative electron acceptor. The anomalous behaviour of D. gigas was reflected to some extent by the hydrogen absorption coefficients for fumarate and sulphate reduction. Effects of fumarate media on the morphology of one strain are recorded.

“…During winter the sulphate-reducing bacteria appear to tolerate a higher level of sulphide than in summer (Fig. 8); Saleh et al (1964) commented that temperature might modify the toxicity of sulphide. In late summer, when much of the sulphide has been released, the gradual decrease in temperature would result in an increase in the amount of sulphide which the sediment can hold, a decrease in sulphide toxicity, and consequently an increase also in bacterial numbers.…”

A major problem associated with the discharge of pulp or paper-mill effluent into shallow estuarine ecosystems, such as the upper L'Etang in Canada or the Don in Scotland, is the development of anoxic conditions in water column and sediment. The effluent modifies the balance, within the ecosystem, between the supply of, and demand for, oxygen. The lignosulphonate component of pulp-mill effluent blocks the transmission of light energy to photosynthetic green plants. The oxygen demand is increased by the microbial degration of the additional organic matter in water and sediment. The addition of cellulosic pulp fibre to the sediment also results in an increase in the concentration of their metabolic by-product, sulphide. The oxidation of sulphide exerts an additional oxygen demand on the system, which is an important factor in the development and maintenance of anoxic conditions. It is suggested that temperature is an important factor in controlling the release of sulphide from the sediment into the overlying water and in modifying the toxicity of sulphide towards the bacterial populations and, therefore, the capacity of the ecosystem to cope with the effluent.
