Abstract
Summary: Octopine-utilizing agrobacteria could be distinguished from non-utilizers on a solid medium containing octopine as the only added nitrogen source if a pH indicator such as bromothymolblue were present. On green bromothymolblue plates, octopine-utilizing strains formed orange-yellow colonies, while those of non-utilizers were translucent. Strains could be tested for utilization of other nitrogen sources such as nopaline by substituting these for octopine in the same medium.This publication has 11 references indexed in Scilit:
