Green mold

Fruit Decay. Finally in the field of diseases are the decays of fruit in transit. Much of the Brazilian fruit is exported, giving a long period from harvest to utilization and in Argentina a slow rail transport plus the use of uninsulated metal cars adds to the problem. Stem-end rot (Diaporthe citri Wolfe and Diplodia natalen-sis Pole-Evans) plus blue and green molds (Penicillium italicum, Wehmer, and P. digitatum, Sacc.) are rampant, and while the Dowicide A (sodium orthophenyl phe-nate)-Hexamine (hexamethylenetetramine) treatment worked out in Florida is satisfactory, import difficulties stand in the way of obtaining needed materials.

A polymerase chain reaction-based test for the identification of Trichoderma harzianum biotypes 2 and 4, responsible for the worldwide green mold epidemic in cultivated Agaricus bisporus. Appl. Microbiol. Biotechnol. 52, 246-250. 

The term mold does not have a dear cut mycological definition. While the yeasts have a preponderantly positive value in food production and utilization, the molds make some positive contributions (some cheeses, etc.), but they partrcipate 111 many more negative ways (leaf molds on plants bine-green molds on fruits machinery mold causes of some foodborne diseases etc,). Some authorities identify all or most mold as saprophytes, as previously defined, This identification, however, is not fully satisfactory in terms of the present loose ways in which the word mold is used m the professional literature. Molds do play an important role in the biodegradation of unwanted substances. 

We then needed to find a way to treat the outer surface of the fruits, where most of the organisms initially propogate in their hosts. In the commercial marketplace the familiar blue-green molds produced by such spores as Penicillium digitatum are the problem. A few infected fruits within a case can ruin a shipment under normal conditions in three to four days. Obviously, deep-rooted organisms will not be controlled by the shallow electron treatment. 

By keeping ethylene concentrations to less than 0.8 ul/1 of air, stem-end decay caused by a species of Fusarium, green mold, loss of orange flavor, and development of off-flavors were minimized. Other volatiles present with and without the ethylene absorber apparently had no effect on quality. Ethylene, produced in copious quantities by rots, enhances respiration and senescence of healthy fruit within the storage facility (281). The importance of ethylene removal has been illustrated also in recent storage studies of lemons in Australia (282, 283, 284, 285). 

Order 3.— Plectascales, the blue and green molds. Examples Aspergillus and Penicillium. 

Penicilliiim glauctun (green mold or mildew), a type of mildew, belonging to the Ascomycetes class of Fungi, forms sage-green crusts on bread, jellies, old boots, gloves, and various pharmaceutical preparations. It consists of a felt-like mass of interlaced tubular... 

Properties A linear polymer extremely resistant to chemicals and to thermal degradation at molding and extrusion temperature, d 1.4, self-extinguishing, dimensionally stable, very low water absorption, outstanding chemical resistance. Natural, black, or olive-green molding powder. Finely divided powder for coatings. 

Penicillin was discovered accidentally in 1928 by the Scottish bacteriologist Alexander Fleming (1881-1995). Fleming noticed that a green mold, which he later identified as Penicillium notatum, had started to grow on a petri dish that he had coated with bacteria. As the bacteria grew towards the... 

Every day or so inspect the jars and check for the slightest sign of contamination. The most common are the green molds PenidiHum and, Aspergillus. If contamination is detected, sea the lid and remove the infected culture from the laboratory and growing facility. If ajar is suspected to be contaminated, mark it for future inspection. 

Common Name Green Mold Black Mold... 

Class Fungi Imperfecti Order Moniliales Family Dematicaeae Common Name The Dark Green Mold. Greek Root From klados which means branched and sporium or spore. The name is in reference to the two celled spores produced on branches from the main body of the conidiophore. 

Macroscopic Appearance Appearing as a granular or powdery bluish green mold, often with a broad whitish rim of new growth. Some species, less frequently encountered, are whitish, yellowish or even reddish in color. Many species exude droplets of fluid from their surfaces having antibiotic properties.
