Phenotypic characteristics and results of PCR tests for the presence of species-specific genes indicate that a number of strains of thermophilic lactic acid bacteria previously considered as belonging to Streptococcus thermophilus are actually closely related to enterococci. In the present study, partial (over 500 nucleotides) sequencing of 16S rRNA genes from 12 strains of thermophilic lactic acid bacteria used as starters for manufacturing sour milk products on the territory of the Commonwealth of Independent States (CIS) has been performed. According to the results of the sequencing, seven of the strains have been classified with Enterococcus durans. The earlier classification (based on PCR tests) of two of the strains as S. thermophilus and three of the strains as E. faecium has been confirmed. The data obtained demonstrate that the enterococci E. durans and E. faecium are widely used as thermophilic starters for manufacturing sour milk products on the territory of the CIS.

Production of polyhydroxybutyrate with high cell density cultivation using thermophile Caldimonas thermodepolymerans.
Bioresour Technol
January 2025
This study investigates the production of polyhydroxybutyrate (PHB) using the thermophilic bacterium Caldimonas thermodepolymerans in fed-batch fermentation. This research highlights the potential of thermophilic bacteria in biopolymer production due to their ability to operate at high temperatures, which reduces contamination risks and enhances energy efficiency. Optimal fermentation conditions were identified at a temperature of 50 °C, with the strain achieving a maximum specific growth rate (μ) of 0.

Natural whey starter (NWS) is an undefined complex culture used in the production of Grana Padano and Parmigiano Reggiano PDO cheeses. The aim of this review is to discuss, in light of the latest research results, the role of NWS as a primary player in the cheese-making process, considering the microbial community scenario. NWS is traditionally produced by fermenting part of the whey collected at the end of a previous cheese-making process.
