Description
Summary:The aim of this study was to determine if different carbohydrates influence the growth of in the presence of carnocyclin A or leucocin A. ATCC PTA-5313 and UAL187 were used to produce carnocyclin A and leucocin A, respectively. Growth curves were modeled for five strains of grown in basal medium supplemented with glucose, sucrose, fructose, mannose, or cellobiose, in the presence of carnocyclin A or leucocin A. The growth of to leucocin A or carnocyclin A was influenced by carbohydrate and/or strain. Carnocyclin A inhibited the growth of more than leucocin A. Growth in media containing glucose, mannose, and fructose increased the sensitivity of some strains of to bacteriocins, while growth in cellobiose and sucrose increased the resistance of to bacteriocins, as evidenced by a shorter lag phase. Strains of developed resistance to both leucocin A and carnocyclin A, but the time to develop resistance was longer when strains are treated with carnocyclin A. Carbohydrate influences the development of resistance of to the bacteriocins, but the ability of strains to develop resistance to leucocin A or carnocyclin A differs. Results of this study indicate that carbohydrates influence the ability of to grow in the presence of bacteriocins.
