Toxicity of zinc to fungi, bacteria, and coliphages: influence of chloride ions.

摘要: A 10 mM concentration of Zn2+ decreased the survival Escherichia coli; enhanced Bacillus cereus; did not significantly affect Pseudomonas aeruginosa, Norcardia corallina, and T1, T7, P1, phi80 coliphages; completely inhibited mycelial growth Rhizoctonia solani; reduced Fusarium solani, Cunninghamella echinulata, Aspergillus niger, Trichoderma viride. The toxicity zinc to fungi, bacteria, coliphages was unaffected, lessened, or increased by addition high concentrations NaCl. in presence NaCl a result synergistic interaction between elevated osmotic pressures but formation complex anionic ZnCl species that exerted greater toxicities than cationic Zn2+. Conversely, decrease with increasing probably reflected levels due Zn-Cl species, which less inhibitory these microbes A. niger tolerated higher at 37 25 degrees C.
