Abstract
Abstract A method for causing the acceleration and the increment of growing of micro-organisms, wherein the culture, immersed in a suitable liquid nutrient medium, is exposed to the action of a magnetic field, generated by a coil, having preferably a ferromagnetic core, and to which an A.C. is fed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
53 words
A METHOD FOR ACCELERATING THE GROWTH OF THE MICROORGANISM PENICILLUM WIDEMANNIM, COMPRISING ESTABLISHING A LIQUID CULTURE MEDIUM OF SAID MICROORGANISM, IMMERSING A COIL COMPRISING A FEW DOZENS OF INSULATED TURNS OF ELECTRICALLY CONDUCTIVE MATERIAL IN SAID CULTURE MEDIUM, PASSING THROUGH SAID COIL, AN ALTERNATING CURRENT HAVING A VOLTAGE OF 1 AND AN AMPERAGE
Claim 2
Independent Claim
53 words
A METHOD FOR ACCELERATING THE GROWTH OF THE MICROORGANISM PENICILLUM WIDEMANNIM, COMPRISING ESTABLISHING A LIQUID CULTURE MEDIUM OF SAID MICROORGANISM, IMMERSING A COIL COMPRISING A FEW DOZENS OF INSULATED TURNS OF ELECTRICALLY CONDUCTIVE MATERIAL IN SAID CULTURE MEDIUM, PASSING THROUGH SAID COIL, AN ALTERNATING CURRENT HAVING A VOLTAGE OF 1 AND AN AMPERAGE
Claim 3
Dependent Claim
15 words
A method as claimed in claim 1, and providing said coil with a ferromagnetic core.
Claim 4
Independent Claim
89 words
A method for increasing the fermentative activity of the microorganism Saccaromyces lactis, comprising establishing a liquid culture medium of said microorganism containing lactose, immersing a coil comprising a few dozens of insulated turns of electrically conductive material in said culture medium, passing through said coil an alternating current having a voltage of 1.4 and an amperage of 1.9, and maintaining said coil immersed in said medium with said current passing therethrough for a period of time sufficient to increase substantially the fermentative activity of said microorganism on said lactose.
Claim 5
Independent Claim
89 words
A method for increasing the fermentative activity of the microorganism Saccaromyces lactis, comprising establishing a liquid culture medium of said microorganism containing lactose, immersing a coil comprising a few dozens of insulated turns of electrically conductive material in said culture medium, passing through said coil an alternating current having a voltage of 1.4 and an amperage of 1.9, and maintaining said coil immersed in said medium with said current passing therethrough for a period of time sufficient to increase substantially the fermentative activity of said microorganism on said lactose.
Claim 6
Dependent Claim
15 words
A method as claimed in claim 3, and providing said coil with a ferromagnetic core.
