AIM To assess esterase profiling of members of Geodermatophilaceae isolated from desert stones and monuments in Tunisia and Egypt. METHODS AND RESULTS Members of Geodermatophilaceae family isolated from desert stones and monuments in Tunisia and Egypt were characterized by partial 16S rRNA sequences. Twenty-five strains were clustered in three dissimilar(More)
Detection of lactic acid bacteria (LAB) bacteriocins producers is of great significance for food industry to establish starter bacterial association and to improve food safety. Eighty oneLactococcus lactis strains, isolated from traditional Tunisian dairy products, were screened for their antibacterial activity. Bacteriocin production in the supernatant was(More)
reformat accordingly to the journal style) 1 Aim: To assess genetic diversity and esterase profiling of members of actinobacteria 2 Geodermatophilaceae isolated from desertic stones and monuments in Tunisia and Egypt. 3 Methods and Results: Geodermatophilaceae Actinobacterial isolated from desert stones and 4 monuments in Tunisia and Egypt, were assigned on(More)
The M(w) of a Lactobacillus sakei intracellular esterase, determined by gel filtration, was compared to those obtained from SDS-PAGE or MALDI-TOF, pointing to a dimeric structure. Its N-terminal sequence and peptide mass fingerprint suggest that it is the putative LSA044 protein from L. sakei 23K genome.
Lactobacillus sakei, a lactic acid bacterium naturally found in fresh meat and sea products, is considered to be one of the most important bacterial species involved in meat fermentation and bio-preservation. Several enzymes of Lb. sakei species contributing to microbial safeguarding and organoleptic properties of fermented-meat were studied. However, the(More)
