Abstract
Enzymatic isomerization procedure of glucose in fructose, characterized in that a strain of Streptomyce violaceoniger that has the following taxonomic characteristics is used as a microorganism product of isomerizing enzyme: Appearance of spores: globulous, with a dimension of 0.9 to 1, 2 microns and with smooth or slightly rough walls, Appearance of the aerial mycelium, brownish-gray spurolate, which liquefies in wet black spots and which presents ramifications of monopodial sperophores. Appearance of the spirals, they are short, they are agglomerated, they have one or two curls Appearance of the vegetative mycelium, it is whitish to yellowish (up to light yellow) It is possible to extract a soluble pigment that is pale pink and that is produced in skim milk Culture on "iron-peptone-agar" medium, without melanoid pigments (which also do not appear in culture on tyrosine-agar) Diastatic action: agar +, starch Proteolytic action. Coagulation of milk good peptonization liquefaction of gelatin; Sugars assimilated by the strain: sucrose inositol rhamanosa raffinose or a mutant strain of this strain.
