"Relationship between aeration, carbon source, and respiration yield and the ethylene production and differentiation of static cultures of Penicillium cyclopium and P. velutinum."

Abstract:
Fully aerated surface cultures of Penicillium cyclopium and P. velutinum grown on liquid medium with 2-oxoglutarate or glutamate (34 mM) produced ethylene in association with the formation of aerial hyphae at about the 5th day (ethylene peak EP 1), its concentration then declined, and rose again during conidiation at about the 7th day (peak EP 2). In P. cyclopium glucose (22.2 mM) shortened differentiation, EP 1 and EP 2 merged, and culture pH dropped to 1.8. Methionine (34 mM) prevented the formation of aerial mycelium in P. cyclopium and penicilli initiation in P. velutinum; ethylene product

Abstract:
The effect of Aspergillus ochraceus, A. versicolor, Penicillium citrinum, P. cyclopium and P. urticae on production of aflatoxin by A. flavus when grown together with A. flavus in rotary shake culture was investigated. The two aspergilli had no apparent effect on aflatoxin production, whereas all three Penicillium species substantially lowered aflatoxin production. The toxins that these penicillia produced when growing in pure culture were not found when the penicillia were grown with A. flavus. However, these toxins had no effect on aflatoxin production added to the growth media, nor did the

Abstract:
This article studies the effect of carbon and nitrogen sources on the biosynthesis of pectinliase enzymes in Penicillium cyclopium. The carbon and nitrogen sources in the nutrient medium influence not only the constructive metabolism of P. cyclopium but also the synthesis of pectinliase enzymes. It is found that the best carbon source is fructose, which provides accumulation of polymethylgalacturonatliase (PMGL) and polygalacturonatliase (PGL) in culture fluid up to 5.0 and 5.7 units/ml. The best nitrogen source is ammonium chloride. When it was added to the nutrient medium as the only nitroge

Abstract:
An assessment of the impact of low-intensity laser irradiation (LILI) and magnetic field (MF) on the biodegradation of a number of industrial products: wood fiberboard (WFB) and polyester caused by filamentous fungi is presented. It has been established that the magnetic field is capable of causing intensive destruction of wood fiberboard and polyester by fungi Alternaria alternata, Aspergillus niger, then the destructive process of WFB in the case of Penicillium cyclopium remained at the control level, and in the case of polyester it slowed down. The action of LILI, on the contrary, increased

Abstract:
En raison de leur mode d'action particulier, les lipases suscitent depuis longtemps un intérêt académique. En effet, bien que solubles en phase aqueuse, elles agissent préférentiellement sur des substrats insolubles. Ces biocatalyseurs suscitent également de plus en plus d'intérêt au niveau industriel, du fait de leurs spécificités variées. La connaissance structurale et fonctionnelle de ces enzymes a beaucoup progressée au cours de ces dix dernières années. C'est dans ce contexte que nous avons étudié les lipases d'une souche fongique : Penicillium cyclopium. Dans un premier temps, leur carac
