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.
Penicillium is often reffered to as Deuteromycetes, or Fungi imperfecti. The name Penicillium comes from the word brush; this refers to the appearance of spores in Penicillium. One species, Penicillium chrysogenum 9' , is classified as a psychrotrophic microorganism.Bancerz et. al.owever, Penicillium is not merely a harmful fungus. It also has many useful species. For example, Penicillium roquefortii is used to make bleu cheese. The color of the cheese comes from the spores (conidia) of the fungus. The spores are injected into the cheese curd during fermentation.
