Mining Biosynthetic Gene Clusters in by Interference Competition Network and Genome Analysis.

is a non-starter lactic acid bacterium (LAB) of interest in the dairy industry for biopreservation. This study investigated the interference competition network and the specialized metabolites biosynthetic gene clusters (BGCs) content in this LAB in order to explore the relationship between the antimicrobial properties and the genome content. Network analysis revealed that the potency of inhibition tended to increase when the inhibition spectrum broadened, but also that several strains exhibited a high potency and narrow spectrum of inhibition.

Identification of Potential Citrate Metabolism Pathways in .

In the present study, we describe the identification of potential citrate metabolism pathways for the lactic acid bacterium (LAB) . A phenotypic assay indicated that four of six strains showed weak (Cm 6-1 and ATCC 35586) or even delayed (Cm 3-1 and Cm 5-1) citrate utilization activity. The remaining two strains, Cm 4-1 and Cm 1-2 gave negative results.

Nested structure of intraspecific competition network in Carnobacterium maltaromaticum.

While competition targeting food-borne pathogens is being widely documented, few studies have focused on competition among non-pathogenic food bacteria. Carnobacterium maltaromaticum is a genetically diverse lactic acid bacterium known for comprising several bacteriocinogenic strains with bioprotective potentialities against the food-borne pathogen Listeria monocytogenes. The aim of our study is to examine the network properties of competition among a collection of 73 strains of C.

High-Throughput Identification of Candidate Strains for Biopreservation by Using Bioluminescent .

This article describes a method for high-throughput competition assays using a bioluminescent strain of . This method is based on the use of the luminescent indicator strain EGDe The luminescence of this strain is correlated to growth, which make it suitable to monitor the growth of in mixed cultures. To this aim, luminescence kinetics were converted into a single numerical value, called the Luminescence Disturbance Indicator (LDI), which takes into account growth inhibition phenomena resulting in latency increase, decrease in the luminescence rate, or reduction of the maximum luminescence.
