Fungal Flora Isolated from Deteriorating Card Board and Corrugated Box Samples in Thane and Bhiwandi, India
Many cellulose based articles have found their way into human requirements and have become articles of necessity, paper being one such article. Card board and corrugated boxes are used as packing materials universally and alike paper, these are vulnerable to invasion by cellulose degrading fungi. The study in regions of Thane and Bhiwandi cities on the outskirts of Mumbai city in Western coastal part of Maharashtra, India focused on the invasion of cardboard and corrugated paper boxes by fungi. Twenty four species of fungi belonging to 11 genera were found on the deteriorating card board and corrugated paper samples during the study, prominent amongst them being the genus Aspergillus, Chaetomium, Curvularia, Trichoderma, Penicillium, Alternaria and five other cellulolytic fungal genera. Growth of fungi resulted in crumbling of the cardboard at places due to loss of strength. Many of the fungal forms isolated were potential health hazards which was cause for concern.
