Four Critical Aspects of a Mould Remediation Mould Mould is part of the Fungi family which is divided into 3 groups.
Most mould cells are filamentous. These cells, individually called hyphae, collectively form mycelium. Well established growth is referred to as colonization. Moulds reproduce by means of spores.
Moulds need 4 things to grow.
Moulds can produce mycotoxins that will be present in the cell wall of the hyphae or the spore even if the organism is dead. Mycotoxins are the moulds’ natural defense system against other microorganisms. Mycotoxins can cause adverse health effects at very low concentrations. Cryptococcus neoformans and Histoplasma capsulatum are primary pathogens (can cause disease in a healthy host) that prefer to grow in bird and bat droppings. Both can be easily aerosolized if disturbed. Aspergillus fumigatus is an opportunistic pathogen (generally requires a suppressed immune system) that can cause the disease aspergillosis. MVOCs Microbial Volatile Organic Compounds The musty, mouldy odors in water-damaged indoor environments are compounds produced by metabolically active bacteria and fungi. While health effects have not yet been attributed to MVOC exposures, their presence is an indicator of microbial contamination.
