“…The antimicrobial effects of sulphiting agents such as sodium metabisulphite have led to their use as food and beverage additives. A previous study (Gould and Russell ) indicated that their function in inhibiting the growth of bacteria, yeast and moulds results from the sulphurous acid (SO 2 .H 2 O) and bisulphite ion (

{HSO}_{3}^{-}

), which can exist in media under acidic conditions (Russell ). Gould and Russell () reported the antimicrobial effects of sulfiting agents to be a result of carbonyl group reactions that inhibit the formation of FAD+, RNA and DNA.…”

This study evaluated efficacy of 42 organic and inorganic salts as possible alternatives to synthetic fungicides for the control of Ilyonectria root rot of kiwifruit. Preliminary in vitro tests showed that ammonium bicarbonate, ammonium carbonate, potassium benzoate, potassium sorbate, sodium benzoate and sodium metabisulphite at 2% completely inhibited mycelial growth of the fungus. No significant differences were observed among these salts and disodium EDTA (P ≤ 0.05). However, the ED50, minimum inhibition concentration (MIC), and minimum fungicidal concentration (MFC) values indicated that sodium metabisulphite was more toxic to Ilyonectria liriodendri than these other six salts. Soil bioassays showed that sodium metabisulphite, sodium benzoate and potassium sorbate at 0.25% completely inhibited mycelial growth of the fungus, whereas potassium benzoate reduced the mycelial growth of fungus by 90.30%; however, the differences in inhibitory effects were statistically insignificant (P ≤ 0.05). Moreover, there was no significant difference between 0.1% sodium metabisulphite and 0.5% ammonium carbonate, 0.75% ammonium bicarbonate and 1.5–2.0% disodium EDTA (P ≤ 0.05). Unlike disodium EDTA, complete inhibitory was observed with ammonium carbonate and ammonium bicarbonate at higher concentrations. However, in root bioassays, applications of 2% ammonium bicarbonate, 1.5% ammonium carbonate and 2% disodium EDTA were phytotoxic to kiwifruit seedlings, but 0.25% four other salts were neither phytotoxic to kiwifruit seedlings nor did it adversely affect root length, root fresh weight and root dry weight of seedling. This study also showed I. liriodendri to be capable of growth in both acidic and basic environments. However, while the fungus showed uninhibited growth at pH values of 5–11, growth decreased significantly at both higher and lower pH values (P ≤ 0.05) and was completely inhibited at pH 12.

“…It is usually added in the sulphite salt form as sodium metabisulphite (Varnam & Sutherland, 1995) and expressed as part per million (ppm) or mg/kg SO 2 (Gould & Russell, 2003). The antimicrobial effect of the sulphite salts is exerted through the undissociated SO 2 molecule.…”

“…Alternatively, by-products of lipid peroxidation have been shown to affect the mitochondrial respiratory chain (25) and are also implicated in DNA damage (19). This could account for the reported inhibitory effect of sodium metabisulfite on energetic metabolism (29) as well as DNA damage as a consequence of both aluminum and sulfites (9,16,31).…”

Aluminum chloride and sodium metabisulfite have shown high efficacy at low doses in controlling postharvest pathogens on potato tubers. Direct effects of these two salts included the loss of cell membrane integrity in exposed pathogens. In this work, four fungal potato pathogens were studied in order to elucidate the role of membrane lipids and lipid peroxidation in the relative sensitivity of microorganisms exposed to these salts. Inhibition of mycelial growth in these fungi varied considerably and revealed sensitivity groups within the tested fungi. Analysis of fatty acids in these fungi demonstrated that sensitivity was related to high intrinsic fatty acid unsaturation. When exposed to the antifungal salts, sensitive fungi demonstrated a loss of fatty acid unsaturation, which was accompanied by an elevation in malondialdehyde content (a biochemical marker of lipid peroxidation). Our data suggest that aluminum chloride and sodium metabisulfite could induce lipid peroxidation in sensitive fungi, which may promote the ensuing loss of integrity in the plasma membrane. This direct effect on fungal membranes may contribute, at least in part, to the observed antimicrobial effects of these two salts.Organic and inorganic salts are widely used in the food industry as preservatives and antimicrobials (26). These salts have a broad spectrum of antimicrobial activity with low mammalian toxicity (22), possess biocompatibility (13), and are generally recognized as safe. Several studies suggest that salts represent an interesting alternative to synthetic fungicides and could find application for the control of plant pathogens (13,20,22), particularly in the case of postharvest diseases that directly affect foodstuffs that will be consumed by the public (12, 21). Recently, organic and inorganic salts have revealed efficacy against postharvest pathogens affecting potato tubers (12,20,21,22,32). Of the tested salts, aluminum chloride and sodium metabisulfite were among the most efficient in controlling potato dry rot (Fusarium sambucinum [20]), soft rot (Erwinia carotovora [32]), and silver scurf (Helminthosporium solani [12]).Recent microscopic work with different potato pathogens, including the gram-negative bacterium E. carotovora (32) and the fungus F. sambucinum (T. J. Avis, M. Michaud, and R. J. Tweddell, unpublished data), has demonstrated that aluminum chloride and sodium metabisulfite produce changes in both bacterial and fungal cells, leading to loss of membrane integrity. Theses results are in agreement with other studies that have postulated that, under certain conditions, aluminum chloride and sodium metabisulfite may act through cell disruption, compromised membrane permeability, and lipid peroxidation (1,3,6,15,17,34).In an effort to gain better insight into the mode of action of these salts and in an attempt to ascertain biochemical determinants in the implicated mechanisms, four fungal potato pathogens were assayed with regard to (i) sensitivity toward aluminum chloride and sodium metabisulfite, (ii) intrinsic...
