  • Method for producing lactic acid by bacterial fermentation
    Patent number: 10927390
    Abstract: A method for producing lactic acid comprises the steps of culturing in a culture medium comprising concentrated whey permeate or delactosed whey permeate as a substrate a bioconversion competent Bacillus bacterial strain capable of converting delactosed whey permeate into lactic acid for a period of time sufficient to allow the bacteria convert at least some of the lactose present in DLP or concentrated whey permeate into lactic acid, and then recovering the lactic acid from the culture medium.
    Type: Grant

  • METHOD FOR CONVERTING POLYETHYLENE TO BIODEGRADABLE POLYHYDROXYALKANOATE
    Publication number: 20150087802
    Abstract: A method for producing polyhydroxyalkanoate (PHA) comprises the steps of culturing in a culture medium comprising pyrolysis wax obtained from the pyrolysis of polyethylene and optionally a surfactant one or more bacterial strains which are capable of accumulating PHA from pyrolysis wax, and recovering the PHA from the culture medium. Typically, the bacterial strains are selected from the group consisting of: A. calcoaceticus BD413; A. calcoaceticus RR8; B. sepacia RR10; P. aeruginosa 3924; P. aeruginosa GL-1; P. aeruginosa PAO1; P. aeruginosa RR1; and P. olevorans.
