摘要

This work is focussed on the search for alternatives to the fungicides conventionally used in the tanning industry. These alternatives should have a high efficiency towards a wide range of fungi and should be less toxic, more environmentally friendly and cost effective.
The main objective of this work is to evaluate the fungicidal capacity of the selected compounds (registered in the 98/8/EC Directive); diiodomethyl-p-tolylsulfone (DIMPTS), 3-iodo-2-propynyl-N-butylcarbamate (IPBC) and thiobendazole (TBZ, 2-thiazol-4-yl-1H-benzo imidazole), against different strains of fungi.
The fungicidal capacity of the selected compounds has been compared with that of fungicides conventionally used in tannery such as TCMTB and a proprietary mixture of phenolic compounds. The fungicidal capacity of the selected molecules was tested against strains of the following fungi, described in the literature as responsible for damage during the process of leather manufacture: Aspergillus niger, Trichoderma harzianum, Altemaria alternata and Penicillium funiculosum.
The Minimum Inhibitory Concentration (MIC) of the studied molecules against the selected fungi has been determined. Thereafter, a comparative study of the fungicidal capacity of the selected fungicides at different offers has been carried out with wet-blue leather. The results obtained confirm that two of the three fungicides studied diiodomethyl-p-tolylsulfone (DIMPTS) and 3-iodo-2-propynyl-N-butylcarbamate (IPBC) are good candidates as alternative fungicides to be used in the leather industry. Their potential application against a wider spectrum of fungi especially those isolated in tannery constitutes the aim of the next study together with toxicity evaluation associated to such application and the determination of the fungicide that remain in the different layers of leather.
