Genotyping of Streptococcus thermophilus strains isolated from traditional Egyptian dairy products by sequence analysis of the phosphoserine phosphatase (serB) gene with phenotypic characterizations of the strains

Abstract

This study presents a novel, simplified procedure based on serB nucleotide sequencing for genotyping Strep. thermophilus. It also provides a pool of phenotypically diverse Strep. thermophilus cultures, from which certain strains could be selected for use in bioprocessing applications including the preparation of fermented dairy products.
