[Conditions of dextranase formation by Penicillium funiculosum 15]. 1975

L I Petrova, and G A Molodova, and N N Burtseva

The influence of the following factors on the synthesis of extracellular dextranase by Pen. funiculosum 15 has been studied: the quantity and age of the inoculum, pH of the cultivation medium, stimulants of the microbial growth, cultivation temperature and time. The optimal amount of dextranase has been found to form under the following conditions: inoculum--3 day mycelium constituting 4%, cultivation time--4 to 7 days, temperature--28 to 29 degrees C, initial pH of the medium--6.0.

UI	MeSH Term	Description	Entries
D010407	Penicillium	A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin.	Penicilliums
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
