Transduction by temperate cyanophage plays an important role in understanding the effects of environmental pollution on genetic function. Using a new isolate, this paper illustrates the influence of contaminants and the rapid variations that result as a virus particle passes through successive hosts. Host‐range and plaque‐morphology, using an extended range of genetically‐differing hosts, compares archetype LPP‐1 cyanophage cultured on microbially contaminated hosts with bacteria‐free cyanophage cultured on pure host strains. Microbial contamination can alter the host‐range and serology of the cyanophage produced. It is suggested that bacteria are involved in the virus infection of cyanophycean hosts and that the study of host‐range and plaque‐morphology can aid in the biological characterization and segregation of mutants illustrating mechanisms of inter generic transfer of genetic material. It is shown that derivatives of archetype LPP‐1, cultured on axenic hosts, possess a host‐range, plaque‐morphology and serology similar or identical to that of the temperate cyanophage, S3.
