Penicillium is unique among microorganisms due to its excellent potential for the secretion of enzyme complex to enable efficient enzymatic conversion of lignocellulosic biomass (Menegol et al., ) and feedstock into simpler l species of Penicillium are capable of producing useful enzymes that degrade complex compound like proteins, xylan, starch, lipids, etc., in.

Penicillium chrysogenum or P. notatum (formerly) is a species of fungus in the genus is common in temperate and subtropical regions and can be found on salted food products, but it is mostly found in indoor environments, especially in damp or water-damaged buildings.

It was previously known as Penicillium notatum. It has rarely been reported as a cause of human : Eurotiomycetes. Penicillium tropicum is a species of fungus in the genus Penicillium which was isolated from soil beneath a Coffea arabica plant in Karnataka in India.

Those species for which the sexual phase is known are placed in the Eurotiales. Found on foodstuffs, leather, and fabrics, they are of economic importance in the production of. Fungi are eukaryotes and have a complex cellular organization.

As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. A few types of fungi have structures comparable to bacterial plasmids (loops of DNA).

Biological classification is the process of grouping living organisms. The five kingdom classification was proposed by ker. He named the kingdoms as Monera, Protista, Fungi, Plantae and Animalia.

The most important method of asexual reproduction is by means of exogenously produced conidia. The conidia are produced on the conidiophores in basigenous or acrogenous chains. Sometimes the conidiophores are aerial and in other cases they are arranged in saucer- shaped acervuli.
