Extracellular Enzymes of Penicillium

Biochemistry of lipolytic enzymes secreted byPenicillium solitumandCladosporium cladosporioides

“…4) Penicillium is one of the most investigated genera, 29) being a good producer of various extracellular enzymes as well as a very important decomposer-recycler of organic matter of all types. 18,30) Cladosporium has been found to be able to produce cellololytic and xylanolytic enzymes, but little is known about its lipolytic enzymes. 25,31) The present study found that two fungal strains, P. solitum 194A and C. cladosporioides 194B, isolated ) lipases as a function of various concentrations of p-nitrophenyl esters as substrates.…”

Pilot-scale production and optimizing of cellulolytic <i>Penicillium oxalicum</i> for controlling of mango malformation

“…When purified active substance applied, significantly inhibited pathogen growth expressed as zone inhibition. Mycoparasitism involving lytic enzymes has been already described as the mechanism of action of Penecillium isolates in the biological control of commercially important plant pathogens [8,10]. Reports on glucanases, cellulase, and the relative importance of any of these systems in the antagonistic process as antifungal agents are well documented [14].…”

“…Application of a conidial suspension of P. oxalicum by watering the tomato seedlings in seedbeds 7 days before transplanting usually results in a significant reduction of Fusarium and Verticillium wilts of tomato plants [9]. Species of Penicillium are versatile organisms and have long been known as producers of a wide variety of extracellular enzymes, some of which are of industrial interest such as cellulose and xylans [10]. These enzymes are capable of degrading components that are normally present in other species of fungi.…”

Modern Concepts in Penicillium and Aspergillus Classification

“…Together with Penicillium chrysogenum Thom, P. funiculosum Thom is the most widely used Penicillium species for biotechnological purposes (Hamlyn et al, 1987). P. funiculosum in the broad sense of is widely used for the production of biochemicals, such as cellulases and dextranases, but it is not known whether these products are produced by P. funiculosum, or similar species such as P. pinophilum Hedgcock or P. minioluteum Dierckx.…”

“…A connection between P. janthinellum and E. javanicum and related species would be of great theoretical and practical importance, especially because strains of the teleomorphic state are also important in biotechnology (Hamlyn et al, 1987).…”
