Determination of the effectiveness of organosulfur compound in the leather industry by adenosine triphosphate (ATP) luminometer

Organosulfur compound is the world’s leading bactericide product for the leather industry. It was reported that it is highly effective for preserving salt and brine solutions, soaking liquors as well as processing materials. This research was conducted in a plant-processing cattle hide in Tuzla. Measurements were carried out at 24 h of wetting back- soaking baths into which was fed organosulfur containing commercial bactericide at the ratio of 0.02% at the beginning of soaking process every month for a year. The objective of this study was to examine the effectiveness of organosulfur compound commercially using adenosine triphosphate (ATP) luminometer. According to ATP test, organosulfur compound had enough effective bactericidal activity during the soaking process. Keywords : Leather industry, soaking, organosulfur compound, ATP.

Possibility of using Rosmarinus officinalis, Myrtus communis and Origanum sp.'s essential oil as fungicide in pickling and tanning processes

The objective of this study was to examine the applicability of Rosmarinus officinalis, Myrtus communis and Origanum sp. essential oil as fungicide against fungus that grows on leather during pickling and tanning processes. In the study, 2-n-Octyl-4-isothiazolin-3-one containing commercial fungicides were also used for control. During the microbiologic tests (ASTM D 4576-86/ 91), the growth of mould species like Aspergillus niger, Alternaria alternata, Penicillium chrysogenum and Trichoderma auroviride that cause problems in leather industry were also investigated against these essential oil and fungicide. As a result of this study, it has been determined that oregano essential oil has most effective antifungal activity.
