The invention solves the problem of obtaining of microbial
amylases in high quantity and consists in proposing of
submerged cultivation proceeding of fungal strain
Aspergillus niger 33-19 CNMN FD 02A, which includes
treatment of spore suspension culture with low-intensity
millimeter waves in continuum regime. Technical result of
invention consists in increasing of amylolytic enzymes
biosynthesis by 34,3 – 31,2 % and reduction of cultivation
cycle of producer with 24-48 h.
Invenţia rezolvă problema obţinerii unor cantităţi sporite de
amilaze microbiene şi constă în elaborarea unui procedeu de
cultivare submersă a tulpinii de fungi Aspergillus niger 33-
19 CNMN FD 02A, care include tratarea suspensie de spori a
culturii cu unde milimetrice de intensitate joasă emise în
regim continuu. Rezultatul tehnic al invenţiei constă în
sporirea biosintezei enzimelor amilolitice cu 34,3 – 31,2 %
faţă de prototip, reducerea duratei de cultivare cu 24 – 48
ore.

The optimization of technological process is achieved by
supplementing the cultivation media of producer-strains with
coordination compounds of transitions metals (Cu, Ni, Mo,
Co, Ti) with different ligands - amino acid, semicarbazone,
dimetilglioxime, as stabilizers of biosynthetical capacity of
producers. The advantages of technologies consists in
increasing of hydrolytical activity with 31,8-75%, reducing
technological cycle with 24 hours;
