Title: David E Tribe: A Pioneer in Ethanol Production Innovations

Introduction

David E Tribe is an accomplished inventor based in Maroubra, Australia. With a strong focus on ethanol production technologies, he holds three patents that contribute significantly to advancements in the field of biofuels. His innovative processes leverage specific bacterial strains to enhance the efficiency and sustainability of ethanol production.

Latest Patents

David’s latest patents include two groundbreaking methods for producing ethanol from carbohydrate substrates. The first patent, titled "Semibatch Ethanol Production," describes a process that involves culturing a flocculant strain of Zymomonas mobilis, such as ATCC 31822. This semi-batch process allows for the flocculent cells to periodically settle, facilitating the removal of ethanol-containing supernatant and the introduction of fresh fermentation medium into the fermentor.

The second patent, "Ethanol Production in a Continuous Process with Cell Recycle," outlines an improved approach for ethanol production from fermentable carbohydrates like glucose, fructose, or sucrose. This method employs continuous culturing of Zymomonas mobilis in a culture medium that incorporates a constant replacement of removed culture medium with fresh medium. Unique to this method is the separation and return of Zymomonas mobilis cells, a practice that enhances ethanol production while circumventing the issues associated with the continuous culturing of yeasts.
