Purification and characterization of thermophilin T, a novel bacteriocin produced by Streptococcus thermophilus ACA-DC 0040

Purification and Characterization of Bacteriocin Produced by Streptococcus Phocae Pi80

Uberolysin: a novel cyclic bacteriocin produced by Streptococcus uberis.

Streptococcus uberis is commonly found in the environment and in association with various bovine body sites and is a major cause of bovine mastitis. Moreover, S. uberis is known to produce a variety of bacteriocin-like inhibitory substances, antimicrobial agents that generally inhibit closely related bacterial species. In this respect, S. uberis strain 42 has previously been shown to produce a ...

Identification, Purification and Characterization of Laterosporulin, a Novel Bacteriocin Produced by Brevibacillus sp. Strain GI-9

BACKGROUND Bacteriocins are antimicrobial peptides that are produced by bacteria as a defense mechanism in complex environments. Identification and characterization of novel bacteriocins in novel strains of bacteria is one of the important fields in bacteriology. METHODOLOGY/FINDINGS The strain GI-9 was identified as Brevibacillus sp. by 16 S rRNA gene sequence analysis. The bacteriocin produ...

Characterization of Exopolysaccharide Produced by Streptococcus thermophilus CC30

An exopolysaccharide (EPS) producing strain CC30 was isolated from raw milk and identified as Streptococcus thermophilus with morphological and 16S sequencing analysis. The strain was shown to produce 1.95 g/L of EPS when grown in skim milk lactose medium at 30°C by increasing the viscosity of the medium. The EPS was isolated and purified, and it was shown to consist of glucose and galactose in...

Detection and Characterization of Weissellicin 110, a Bacteriocin Produced by Weissella cibaria

Background: Weissellicin 110 is the only bacteriocin reported in Weissella cibaria up to now. This bacteriocin represents several unique features. This is the first report on the gene sequence that encodes for the bacteriocin. Objectives: Providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives. Materi...
