The bacteriocin-producing strain Enterococcus faecium ST5Ha was isolated from smoked salmon and identified by biomolecular techniques. Ent. produces a pediocin-like bacteriocin with activity against several lactic acid bacteria, Listeria spp. some other human food pathogens, remarkably HSV-1 virus. Bacteriocin produced at high levels in MRS broth 30 degrees C 37 C, reaching maximum production of 1.0 x 10(9) AU/ml, checked ivanovii ATCC19119 as target surrogate pathogenic monocytogenes....
To evaluate the probiotic properties of strains isolated from smoked salmon and previously identified as bacteriocin producers. Strains Lactobacillus curvatus ET06, ET30 ET31, fermentum ET35, delbrueckii ET32, Pediococcus acidilactici ET34 Enterococcus faecium ET05, ET12 ET88 survived conditions simulating gastrointestinal tract (GIT) produced bacteriocins active against several Listeria monocytogenes, but presented very low activity other lactic acid bacteria (LAB). Cell-free supernatants...
Abstract Nine LAB bacteriocin-producers, isolated from vacuum-packaged cold-smoked salmon (CSS), were phenotypically and genotypically identified as Lactobacillus curvatus, delbrueckii, fermentum, Enterococcus faecium, Pediococcus acidilactici. Their bacteriocins partially characterized. The antimicrobial spectrum was determined against Listeria monocytogenes, E. faecalis, Staphylococcus aureus. molecular size of ranged 2.8 to 4.5 kDa. They inactivated by treatment with proteolytic enzymes...
Repeated exposures to sodium arsenite in vitro of a normal strain Trypanosoma gambiense and one highly resistant reduced tryparsamide failed induce resistance this compound. A T. remained infective after somewhat higher concentrations than tryparsamide-resistant strain, although the respiration latter was slightly more that former. The had no influence on response trypanosomes tryparsamide, arsenite, or compound NF 114. measurably decreased during 21 months when contact with drug. slight...
Total DNA extracted from bacteriocinogenic and potential probiotic lactic acid bacteria (LAB) (Lactobacillus curvatus ET06, ET30 ET31, Lactobacillus fermentum ET35, delbrueckii ET32, Pediococcus acidilactici ET34 Enterococcus faecium ET05, ET12 ET88), have been screened for presence of more than 50 genes related to production biogenic amines (histidine decarboxylase, tyrosine decarboxylase ornithine decarboxylase), virulence factors (sex pheromones, gelatinase, cytolisin, hyaluronidase,...
This work has evaluated the effect of processing conditions on acceptance smoked catfish (P. fasciatum). The variables studied were thickness (1.9 and 3.6 cm), salting time (30, 60 90 min) smoking (4, 5 6 h at varying temperatures). influence species pirinampu P. fasciatum) freshness fillets also studied. Smoked 1.9 cm had moisture contents significantly (p < 0.05) lower salt concentration was greater than in salted thickness. thinner received greatest scores for texture appearance....
Potatoes are one of the most important food crops in Albania. Virus diseases on this crop major threat to production. According EPPO list spread and viruses Albania Potato virus X (PVX), Y (PVY), leafroll (PLRV). The identification is done using ELISA test. Monitoring potential vectors performed. Samples have been collected spring autumn during plant vegetation. Some species aphids like Macrosiphum euphorbiae (Thomas), Myzus persicae (Sulzer), Aulacorthum solani (Kaltenbach) were observed....
