摘要: Publisher Summary This chapter discusses the production of bacteriocins by strains group A, B, H, and D streptococci. The frequency bacteriocin A streptococci is tabulated. mechanisms inhibition are in many cases not clearly characterized must always be attributed to action bacteriocins. It has been reported that some inhibitory phenomena among caused toxic hydrogen peroxide. also true for Streptococcus sanguis (group H). Wolff Duncan described a bactericidal substance produced streptococci, which an other than bacteriocin. Among from milk, substances ways resemble antibiotics used therapeutic purposes—for example, Diplococcin Nisin.
