Title: Innovations by Herbert A Schroeder

Introduction

Herbert A Schroeder is a notable inventor based in Fort Collins, CO (US). He has made significant contributions to the field of nutritional products and adhesive resins, holding a total of 4 patents. His work focuses on utilizing microorganisms and lignin in innovative ways to enhance agricultural and industrial processes.

Latest Patents

One of his latest patents is titled "Process for the production of nutritional products with microorganisms using sequential solid substrate and liquid fermentation." This invention describes a method where rural biomass and other cellulosic materials are converted into a protein-enriched animal feed supplement or single-cell protein through a series of bio-reactions. The first stage involves a solid substrate bio-reaction, where enzymes like cellulase are produced. These enzymes are then used in a second-stage bio-reaction, which involves pretreating the feedstock to hydrolyze hemicellulose and partially digest starch. The result is a substantial digestion of the feedstock, allowing for the harvesting of single-cell protein in an aerobic bio-reaction, while ethanol is produced in an anaerobic reaction. The products of this invention serve as valuable feed supplements to enhance the protein content of animal feed.

Another significant patent by Schroeder is the "Method for recovering and using lignin in adhesive resins." This patent outlines a process for isolating demethylated lignin from a lignin-containing aqueous solution by adding an organic solvent, typically a polar and partially water-immiscible substance like ethyl acetate. The mixture is acidified to separate the water layer, discarding it, while the organic solvent layer contains the demethylated lignin. This lignin can then be dissolved in an alkaline solution with an aldehyde source to produce a resol-type resin, which has various applications in adhesive formulations.
