- Penicillium. Description. Penicillium is a fungus, and is the most abundant mold source in soil. There are more than 150 species of penicillium. Penicillium that is more than two-weeks old is bluish in color. Penicillium is a cryophilic fungi, which means it likes the cold, growing best at 34 degrees (the temperature of a refrigerator). It is xerophilic, which means it can obtain moisture from the air if humidity is at 60% or higher. Photos.

What are the chemical properties of Penicillin? Best Answer: From cultures of the mold Penicillium chrysogenum, Penicillin is an organic acid. It acts as an antibiotic through lysis of bacterial cell walls, specifically its peptidoglycan layer.Through its attachment to penicillin binding proteins, it can inhibit the synthesis of the bacterial cell wall, thus killing the bacteria.t acts as an antibiotic through lysis of bacterial cell walls, specifically its peptidoglycan layer.

Black Mold and Other Toxic Mold Black Mold and Other Toxic Mold. Mold is a type of fungi which is fluffy and can be white, yellow, pink, brown, green, gray, or black. Molds produce invisible spores which act like seeds and travel easily through the air. Under severe conditions thousands of mold spores can be carried in each cubic foot of air.

Is cheese really mold? Blue-mold cheeses like Roquefort, Gorgonzola, and Stilton are produced by inoculating loosely pressed curds with Penicillium roqueforti or Penicillium glaucum molds. The mold grows within the cheese as it ages. These cheeses have distinct blue veins and, often, assertive flavors. Their texture can be soft or firm.

Penicillin While the number of penicillin-resistant bacteria is increasing, penicillin can still be used to treat a wide range of infections caused by certain susceptible bacteria, including Streptococci, Staphylococci, Clostridium, and Listeria genera.enicillin is a secondary metabolite of certain species of Penicillium and is produced when growth of the fungus is inhibited by stress. It is not produced during active growth. Production is also limited by feedback in the synthesis pathway of penicillin.

- They are mainly bactericidal, are especially active against gram-positive organisms, and, with the exception of hypersensitivity reactions, show a particularly low toxic action on animal tissue. Penicillins are a certain collection of antibiotics that eliminate infection causing bacteria.Also known in short as pen or PCN, they originate from a type of fungi called Penicillium fungi. They are used in the treatment or prevention of many different bacterial infections, usually caused by Gram-positive organisms.enicillins are all β-Lactam (Beta-Lactam) antibiotics, which are antibiotic molecules with a β-Lactam nucleus. There are a number of penicillin types, that react to bacteria in a variety of degrees, some of these are: 1  ampicillin.

Penicillium Penicillium species are one of the most common causes of fungal spoilage in fruits and vegetables. Penicillium italicum and Penicillium digitatum are the most common attackers of citrus fruits, while Penicillium expansum is known to attack apples. P. digitatum works by producing ethylene to accelerate ripening.any species produce mycotoxins; for example, P. expansum produces one called patulin. Most of these species resemble each other in color characteristics, style of decay, and infection symptoms; they fall under a general category called blue mold. P. expansum is one of the most aggressive species.
