Effect of phenolic acids on glucose and organic acid metabolism by lactic acid ...
Campos, Francisco M.; Figueiredo, Ana R.; Hogg, Tim A.; Couto, José A.The influence of phenolic (p-coumaric, caffeic, ferulic, gallic and protocatechuic) acids on glucose and organic acid metabolism by two strains of wine lactic acid bacteria (Oenococcus oeni VF and Lactobacillus hilgardii 5) was investigated. Cultures were grown in modified MRS medium supplemented with different phenolic acids. Cellular growth was monitored and metabolite concentrations were determined by HPLC-R...

Hogg, Tim A.; Couto, José A.; Teixeira, Paula; Malcata, F. MalcataMany of the difficulties faced nowadays by society at large in maintaining a safe food supply can be effectively addressed by more and (preferably) better science. However, excellence in science will become more and more dependent on sharing of data and expertise - the nuclear idea emphasized in this viewpoint article, which conveys the major points presented and discussed by the senior author in the (invited) ...

Torres, André F.; Mesquita, Paulo A. R.; Campos, Francisco M.; Couto, José A.; Tóth, Ildikó V.; Rangel, António O. S. S.; Hogg, Timothy A.A flow injection analysis (FIA) system was developed for the determination of phosphate efflux from wine lactic acid bacteria (Oenococus oeni and Lactobacillus hilgardii) as an indication of cell membrane damage. The system allowed the direct injection of the cell suspension, avoiding the filtration step, with minimumsample treatment andminimized reagent consumption. The developed system is characterized by a l...
