Synopsis. Eighteen strains of algae, including 17 formerly symbiotic with Paramecium bursaria , were tested for capacity to release sugar. Detectable amounts of sugar were found in the supernatant fluids from 10 strains, including 6 strains infective for aposymbiotic P. bursaria syngen 2. The other 4 sugar‐releasing strains were noninfective and released ˜26–46 m̈g sugar/mg dry cell weight compared to ˜90–175 m̈g sugar/mg dry cell weight for infective strains. This relationship of infectivity with capacity to release sugar supplements data that indicate a relationship of infectivity with resistance to Con A agglutination. The correlation is completed if we assume that resistance to Con A agglutination and capacity for sugar release must both be present in an algal strain for infectivity. The data thus strongly suggest that these 2 characteristics must be present for infectivity by any algal strains for aposymbiotic P. bursaria syngen 2.
