Publication number: 20200190552Abstract: A method of enzyme-based processing of plant-based materials includes steps of providing a bulk amount of a plant-based material having a substantial amount of the cell walls in a physically-intact condition; providing an enzyme broth having an enzyme capable of breaking down the cell walls in the physically-intact condition; combining the bulk amount of the plant-based material with the enzyme broth; allowing the enzyme capable of breaking down the cell walls in the physically-intact condition to break down at least a portion of the cell walls in the physically-intact condition to thereby produce intact oil bodies, hydrolyzed carbohydrates, and intact protein bodies; collecting a first product including the intact oil bodies; collecting a second product including the hydrolyzed carbohydrates; and collecting a third product including the intact protein bodies.Type: ApplicationFiled: December 16, 2019Publication date: June 18, 2020Inventor: Lu-Kwang Ju

Publication number: 20200190554Abstract: Disclosed herein are methods and compositions for antimicrobial quantification and functional measurement. In one aspect, a method for quantifying antimicrobial comprises: obtaining a biological sample from a patient receiving an antimicrobial; incubating the biological sample with a reference microbial strain and a fluorophore for detecting cell lesion; measuring a first signal of fluorescent intensity in the incubated biological sample using flow cytometry; and comparing the first signal to a calibrating curve previously generated for the antimicrobial, thereby quantifying the antimicrobial present in the biological sample.Type: ApplicationFiled: June 1, 2018Publication date: June 18, 2020Inventors: Cidalia Irene Azevedo Pina Vaz, Acacio Agostinho Goncalves Rodrigues
