Última Antimicrobial and antioxidant activities of cactus polyphenols extract on seafood preservation ArchiMer Besbes, Nadia; Joffraud, Jean-jacques; Ben Khemis, Ines; Amri, Mohamed; Sadok, Saloua. The present work investigated the antimicrobial and antioxidant activities of polyphenols extracted from cactus (Opuntia ficus indica) fruit-peels on sardine fillets during refrigerated storage. Biochemical, microbiological and sensorial indicators of treated sardine fillets; were studied comparatively to control lot. Microbial communities were characterized using phenotyping and molecular identification of bacterial isolates; and culture-independent method (PCR-TTGE) for fingerprinting of bacterial DNA extracted from fillets. A principal component analysis (PCA) of all the studied descriptors and variables revealed that discrimination along first principal component (PC1) was mainly correlated positively with peroxidation level and storage time but...

This study describes a polymerase chain reaction using restriction fragment length polymorphism (PCR-RFLP) assay based on the 16S rRNA mitochondrial gene to identify commercial food products of wide range of Penaeidae and Pandalidae shrimp species commercialised in the Tunisian market. Phylogenetic analyses on 16S rRNA mitochondrial gene were used to study the relationships among the considered species. Penaeidae shrimp species was easily differentiated and confirmed by direct sequencing, showing a genetic distance of 0.34 with respect to Pandalidae species. A rapid and reliable PCR method using restriction fragment length polymorphism (RFLP) with three restriction enzymes (HpyCH4III/ MboI / AluI) was optimized for unambiguous differentiation of shrimp...
