TLDR
New starter cultures of lactic acid bacteria with an industrially important functionality are being developed that can contribute to the microbial safety or offer one or more organoleptic, technological, nutritional, or health advantages.Abstract:
The production of fermented foods is based on the use of starter cultures, for instance lactic acid bacteria that initiate rapid acidification of the raw material. Recently, new starter cultures of lactic acid bacteria with an industrially important functionality are being developed. The latter can contribute to the microbial safety or offer one or more organoleptic, technological, nutritional, or health advantages. Examples are lactic acid bacteria that produce antimicrobial substances, sugar polymers, sweeteners, aromatic compounds, vitamins, or useful enzymes, or that have probiotic properties.read more

Coupling the recombineering to Cre-lox system enables simplified large-scale genome deletion in Lactobacillus casei
TL;DR: This strategy is the first instance of sequential deletion of large-scale genome regions in L. casei and it is expected this efficient and inexpensive tool can help for rapid genome streamlining and generation restructured L. casesi strains used as cell factories.

Effect of microfluidization on the microstructure and physical properties of a novel yoghurt formulation
TL;DR: In this article, a new method to form emulsion-based yoghurt like gels from, but not limited to hazelnut, was developed, and the results showed that microfluidization greatly improved physical properties of the HNPs with significant increase in firmness values.

Studies on the low-salt Chinese potherb mustard (Brassica juncea, Coss.) pickle. I—The effect of a homofermentative l(+)-lactic acid producer Bacillus coagulans on starter culture in the low-salt Chinese potherb mustard pickle fermentation
Dayun Zhao,Xiaolin Ding +1 more
TL;DR: As a functional starter culture, inoculated B. coagulans B179 can effectively improve desired native LAB growth and inhibit the growth of undesired fungi, which will thereby allow it to shorten fermentation period and enhance the pickle quality in the low-salt potherb mustard pickle production.

Characterization of a Prophage-Free Derivative Strain of Lactococcus lactis ssp. lactis IL1403 Reveals the Importance of Prophages for Phenotypic Plasticity of the Host.
TL;DR: It appears that prophages contribute significantly to lactococcal cell physiology and might play an important role in the adaptation of L. lactis to cultivation and environmental conditions.
