The present invention discloses means, use and non-GM method for modulating proteins in microorganisms. This method comprising steps of providing a system comprising a plasma discharge source, the plasma; the plasma discharge electric field is in the range of about 200 to about 500 v/m; and a plasma modifying mechanism comprising (1) at least one magnetic material, and at least one piezoelectric material, and (2) at least one optical crystal material, the plasma modifying mechanism providing modified plasma output having frequencies in the range of about 3 KHz to about 30 KHz; and discharging the plasma towards the microorganisms in a pulsed profile; thereby modulating proteins from the target microorganisms. The invention also discloses means, use and non-GM method for de novo generating of proteins in microorganisms from within the proteome of the microorganisms. The method comprises steps of providing a system as defined above, and discharging the plasma towards microorganisms in a pulsed profile, thereby activating proteins from the target microorganisms to de novo generating of proteins in microorganisms from within the proteome of the microorganisms.
