Systems and methods of improved fermentation

摘要

Devices, systems and methods for processing cellulosic material to produce fermentable sugars are provided. Devices, systems and methods for increasing fermentation rates of microbes via biostimulation are provided. Electrodes are preferably positioned along an interior or exterior of a tube-shaped component to administer electromagnetic/electric pulses to a solution comprising a microbe. Systems can advantageously be used in new biofuels production plants, or in existing biofuels production plants without the need for significant retrofits.

主权项

1. A method for processing cellulosic biomass, comprising:
feeding a first set of electric pulses to a solution comprising the cellulosic biomass, wherein the first set of electric pulses is fed to the solution at a first frequency; and feeding a second set of electrical pulses to the solution at a second frequency different from the first frequency, at one or more voltages of at least 500 V/cm to produce fermentable sugars.
