Experimental Formation of "Corn Cob" In Vitro

Organisms isolated from corn cob were examined for aggregation with Bacterionema matruchotii. Such aggregations, interpreted as corn cob formation, in vitro, occurred with five isolates identified as Streptococcus sanguis. A cell-surface component of Streptococcus sanguis or a phospholipid-related substance of Bacterione ma matruchotii appeared to be involved.
