Combined effect of pediocin bacHA-6111-2 and high hydrostatic pressure to contr...
Castro, S. M.; Silva, J.; Casquete, R.; Queirós, Rui; Saraiva, J. A.; Teixeira, P.In and ex situ production of bacteriocin (bacHA-6111-2) combined with high hydrostatic pressure (300 MPa, 5 min, 10ºC) were assessed on the survival of Listeria innocua reviously inoculated in Alheira, a traditional Portuguese fermented meat product. The effect was evaluated immediately after each treatment, alone and combined, and during 60 days of storage (4ºC). For higher concentrations of L. innocua, a bact...
Adsorption of triclosan on single wall carbon nanotubes: A first principle appr...
Castro, S. M.; Araújo, A. B.; Nogueira, R. F.P. [UNESP]; Guerini, S.Made available in DSpace on 2018-12-11T17:09:49Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-05-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Fundação de Amparo à Pesquisa e ao Desenvolvimento Científico e Tecnológico do Maranhão; The interaction of triclosan on (8,0) and (5,5) single wall carbon nanotube (SWCNT) was investigated using density functional calculations. The r...
Biopreservation strategies in combination with mild high pressure treatments in...
Castro, S. M.; Kolomeytseva, M.; Casquete, R.; Silva, J.; Queirós, R.; Saraiva, J. A.; Teixeira, P.Thrombomodulin (TM) is an endothelial cell membrane protein that acts as a major cofactor in the protein C anticoagulant pathway. The EGF-like domains 4-6 of TM (TM456) are essential for PC activation. In this study, we proposed a liposomal recombinant TM conjugate to mimic the membrane TM structure and its anticoagulant activity. First, a DSPE-PEG2000-TM456 was successfully synthesized by site-specific conjuga...
Enhancement of bacteriocin production and antimicrobial activity of pediococcus...
Garcia, J. M.; Castro, S. M.; Casquete, R.; Silva, J.; Queirós, R.; Saraiva, J. A.; Teixeira, P.The effect of sequential treatments of pressure (50-150 MPa, 10 degrees C, 5 min) and temperature (57 degrees C, 15 min) on the survival and bacteriocin production of Pediococcus acidilactici HA-6111-2 cells in the exponential growth phase was assessed. The growth curves were fi tted with the modifi ed Gompertz model, and the estimated maximum specifi c growth rate was considered to be pressure dependent. A del...
Effect of thermal and high pressure pre-treatments and of high pressure shift f...
Castro, S. M.; Van Loey, A.; Saraiva, J.; Smouth, C.; Hendrickx, M.Industrially, bell peppers are usually fiozen, after being thermally blanched, to be consumed in salads after thawing. However, texture tend to decrease after this process. Therefore, several thermal (55°C) and thermalhigh-pressure (200MPa, 25°C and 55°C) pre-treatments, with and without calcium (0.50%, wlv) addition, were studied for their possible effect on texture improvement of green bell peppers. The tempe...

Thermal inactivation of pectin methylesterase from peppers (Capsicum annum)
Castro, S. M.; Van Loey, A.; Saraiva, J.; Smout, C.; Hendrickx, M.Pectin methylesterase (PME) from green bell peppers (Capsicum annuum) was extracted and purified. Isothermal inactivation of purified pepper PME at pH 7.5 could be described by a fractional conversion model for lower temperatures (55-57°C) and a biphasic model for higher temperatures (58-70°C).
