Halophilic and halotolerant actinomycetes The abundance
of halophilic and halotolerant actinomycetes from the sediments of
crystallizer pond at 4 different salinities and in 3 different isolation
media is shown in Fig. 1. The actinomycetes numbers were high at
lower salinities (35 psu and 50 psu), suggesting the abundance of
halotolerant actinomycetes in this saltern. R2A agar was found to
be a suitable medium for isolation of hypersaline actinomycetes,
irrespective of whether the isolates were halotolerant or halophilic.
