Purification and partial characterization of a tripeptidase from Pediococcus pentosaceus K9.2
Article Abstract:
A research was conducted to study the characterization and purification of a tripeptidase from the cytoplasm of Pediococcus pentosaceus K9.2 isolated from Feta cheese. The properties of the tripeptidase was compared with those off a tripeptidase isolated from Lactococcus lactis subsp. cremoris and L. latis subsp. cremoris. Gel filtration chromatography was utilized to determine the molecular mass of the enzyme. Results indicated that the peptidase did not cleave dipeptides, oligopeptides and amino acid derivatives.

Role of Streptococcus thermophilus MR-1C capsular exopolysaccharide in cheese moisture retention
Article Abstract:
A study was conducted to investigate the functions of Streptococcus thermophilus MR-1C capsular exopolysaccharide in cheese moisture retention. Plasmid DNA was determined from S. thermophilus MR-1C while the oligonucleotide primers utilized to amplify eps gene fragments were designed with the S. thermophilus Sfi6 eps gene cluster sequence. Results showed that galactose fermention was expressed in S. thermophilus DM10.

Development and characterization of lactose-positive Pediococcus species for milk fermentation
Article Abstract:
A study was conducted to develop and characterize Lac+ Pediococcus acidilactici and Pediococcus pentosaceus strains for milk fermentation. The strains were constructed by transformation with the naturally occurring 35-kb Lactococcuslactis lactose plasmid pPN-1. Results showed the potential of theLac+ Pediococcus species as replacement cocci for Streptococcus thermophilus in Italian cheese starter blends.
