Title: Dennis H. Steinberg: Innovator in Lactose Hydrolysis

Introduction

Dennis H. Steinberg is a notable inventor based in Philadelphia, PA (US). He has made significant contributions to the field of dairy science, particularly in the area of lactose hydrolysis. With a total of 2 patents, his work has had a profound impact on the food industry.

Latest Patents

Steinberg's latest patents focus on the use of mutant strains of Streptococcus thermophilus for lactose hydrolysis. The first patent describes mutant strains with defective lactose transport systems, specifically those with the phenotype sucS.sup.+ and gluS.sup.-, lacS.sup.-, and .beta.gal.sup.+. These strains are effective in processes aimed at hydrolyzing lactose, demonstrating thermostability and producing .beta.-galactosidase. This innovation allows for lactose hydrolysis before and during pasteurization, providing improved methods for creating reduced lactose dairy products. The second patent reiterates similar findings, emphasizing the effectiveness of mutant strains with the phenotype gluS.sup.31, lacS.sup.-, sucS.sup.+, and .beta.gal.sup.+ in lactose hydrolysis processes.
