Biochemically, the leather is a complex organic material which contains proteins, fats, glycerides, minerals etc. Hence, it forms a favorable medium for the growth of fungi. Biodeterioration of leather and its articles, during manufacture, storage, and in user conditions is caused by fungi. Because during finishing operations some substances like gelatin, albumins and casein etc. are used as protein binders. These substances make leather highly susceptible and most vulnerable to fungal attack as they serve like nutrients under suitable relative humidity, temperature and moisture of the leather surface. The growth of leather deteriorating fungi depend on the production of many enzymes, the most important being the proteolytic and lipolytic enzymes. These enzymes play an important role during deteriogenesis of the leather by deteriogens. Such facts prompted the isolation of 47 fungi from ten types of leather samples belong to different animals and in vivo estimation of enzyme protease of selected common leather infesting fungi at different temperature and suitable relative humidity and duration of storage. Data revealed that 300 C temperatures is the most conducive for the secretion of protease enzyme in comparison to 250 C and 350 C temperature.
