Therefore, at sea level, air is 784 times less dense than water. Expressed in another way, a volume of air at sea level has 0.1275% of the density of the same volume of water. Dirt is about 2.5 times the density of water.
Penicillium (/ËpÉnÉªËsÉªlÉªÉm/) is a genus of ascomycetous fungi of major importance in the natural environment as well as food and drug production. Some members of the genus produce penicillin, a molecule that is used as an antibiotic, which kills or stops the growth of certain kinds of bacteria inside the body.enicillium species are present in the air and dust of indoor environments, such as homes and public buildings. The fungus can be readily transported from the outdoors, and grow indoors using building material or accumulated soil to obtain nutrients for growth.
Its natural habitat is in hay and compost. some species withstand heat eg; Aspergillus fumigatus (pathogenic type) these are commonly found in compost. This type of mold can be found everywhere indoors (prefers damp materials) and outdoors.spergillus can produce mycotoxins â these are often found in contaminated foodstuff and are hazardous to the consumer. Many toxins of this type of mold have been identified and depend greatly on genus and species.
