I went on to google more info........learnt something new today actually.


These are the commonly found molds that thrive in the home environment, of them cause respiratory health issues and some even more dire issues in the elderly, young and immunosuppressed.

Alternaria
Aspergillus
Aureobasidium
Chaetomium
Cladosporium
Fusarium
Penicillium
Stachybotrys Chartarum
Black mold or stachysbotrys chartarum is also called toxic mold. This is due to the fact that this type of mold creates toxic compounds known as mycotoxins. The compounds cause those that breathe the mold in to develop breathing issues, sinus infections, depression, fatigue, asthma attacks and more. This type of mold can be identified by its musty smell and is found in areas that stay damp, like air conditioning pipes and ducts.

Serpula Lacrymans
Trichoderma
Ulocladium



Not all produce mycotoxins. These are the species/types that produce mycotoxins.
Stachybotrys chartarum or more commonly known as toxic black mold that is commonly connected to Sick Building Syndrome due to it always being found in air-conditioning equipment
Aspergillus species
Penicillium species
Chaetomium globosum
Trichoderma species



The ang moh pro is correct. Mycotoxins are produced as secondary metabolites of some indoor molds while they thrive and reproduce. While most living mold spores themselves can cause the allergy as your immune system recognises them as foreign invaders and attacks them, mycotoxins are also one of the responsible allergens. Molds are generally not toxic themselves, but some are toxigenic, ie they produce mycotoxins as a secondary metabolite in a damp environment while living and reproducing.

While living or dormant mold spores can be inactivated by heat, mycotoxins are not destroyed by heat that are found in cleaning processes and thus only physical removal works. Not even at the smoking point of cooking oil at 200+ deg C. The stachybotrys chartarum black mold that is commonly found in always damp air-conditioning systems is such a toxigenic mold that produces mycotoxins.
