ABSTRACT: Sausages are highly susceptible to microbial spoilage. Lactic acid bacteria (LAB) is the main group of spoilage in vacuum packed cooked sausages. To control growth natural antimicrobials have been used as food preservatives. The aim this study was identify strains lactic isolated from spoiled commercial Calabresa sausages and use them an vitro challenge with antimicrobials, nisin (NI)...

Patterned coatings based on biodegradable crosslinked poly(ester/carbonate) have been prepared by photo-induced ring-opening polymerization of a liquid bifunctional trimethylene carbonate-based monomer using poly(ε-caprolactone) triol as initiator and guanidine superbase photogenerator activated irradiation at 385 nm. The influence various parameters gel time such components molar ratios, or re...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

We present a simple query-algorithm for learning arbitrary functions of k halfspaces under any product distribution on the Boolean hypercube. Our algorithms learn any function of k halfspaces to within accuracy ε in time O((nk/ε)) under any product distribution on {0, 1} using read-once branching programs as a hypothesis.. This gives the first poly(n, 1/ε) algorithm for learning even the inters...

The release of the anti-cancer drug paclitaxel (PTX) from microspheres of the bioresorbable poly(ε-caprolactoneoxyethylene-ε-caprolactone) tri-block copolymer was studied. The microspheres, both loaded and not with PTX, were prepared by emulsion-evaporation technique, then characterized by SEM, AFM, total reflection and spotlight FT-IR spectroscopy, and DSC. The quantities of PTX released were ...
