In the tanning industry the problem of micro-organisms able to grow on leather during the different processing phases is well known. Wet-white leathers are excellent substrates for fungal growth: storage temperature, acid pH, presence of water, proteins and fats constitute the most important conditions for the development and growth of a lot of moulds such as Penicillium spp, Aspergillus spp. and Trichoderma viride. The fungal contamination appears as coloured stains on the leather, usually permanent. Microbiological testing has been performed on wet-white leather tanned with Ti-Al based tanning agent using an inoculum with 4 species of fungi. This study revealed that the Ti-Al-tanned wet-white leather is attacked by all types of fungi studied.
