Abstract

Prezenta inventie se refera la un procedeu de obtinere, pe cale fermentativa, a fenoximetilpenicilinei, ce consta în aceea ca tulpina Penicillium chrysogenum H15 înregistrata în colectia IA Iasi la nr.51217/1967 se cultiva pe un mediu de cultura ce contine extract de porumb, fosfat de sodiu, sulfat de sodiu, carbonat de calciu, acid fenoxiacetic si ulei vegetal, la temperatura de 26...27 degree C si pH=6,0...6,6, dupa 10...15 h se începe adaugarea de hidrati de carbon alesi dintre dextroza, glucoza sau amestec de glucoza si lactoza în cantitate necesara pentru a mentine o concentratie în zaharuri de 0,2...1,2%, sulfat de amoniu în cantitate necesara pentru obtinerea de 0,02...0,04% amoniac, ulei de floarea-soarelui ca antispumant si sare de sodiu a acidului fenoxiacetic, temperatura pe tot parcursul biosintezei este de 24...25 degree C, aeratia este de 0,8...1,5 l/l mediu/min, iar timpul de biosinteza este 16...18 h.The present invention relates to a process for obtaining fermentation of phenoxymethylpenicillin, which consists in that the strain of Penicillium chrysogenum H15, registered in the Iasi Collection Iasi at No. 51217/1967, is grown on a culture medium containing corn extract, sodium phosphate, sodium sulphate, calcium carbonate, phenoxyacetic acid and vegetable oil at 26 ... 27 ° C and pH = 6.0 ... 6.6, after 10 ... 15 h starts the addition of carbonate hydrates selected from dextrose, glucose or a mixture of glucose and lactose in an amount necessary to maintain a concentration in sugars of 0.2 ... 1.2%, ammonium sulphate in the amount required to obtain 0.02 ... 0,04% ammonia, sunflower oil as an anti-sparking agent and sodium salt of phenoxyacetic acid, temperature throughout biosynthesis is 24 ... 25 ° C, aeration is 0,8 ... 1, 5 l / l medium / min, and the biosynthesis time is 16-18 h.
