Ten strains of genus
Streptomyces
were isolated from phyllosphere of three
mangrove tree species viz.,
Sonneratia caseolaris
,
Kandelai candel
and
Exoecocaria aggallocha
found in Bhitarkanika mangrove ecosytem of Orissa. According to
physiological and biochemical data, all ten isolates were taxonomically assigned to
the species
Streptomyces exfoliatus
. However, all the strains varied morphologically
and exhibited different extracellular activity. This is a unique report on this mangrove
ecosystem as far as
Streptomyces occurrence is concerned.
