Abstract
Enumeration and isolation of luminous
bacteria from seawater and sponges collected
from the coastal regions of northern Taiwan
were performed in the present study. Plate
counts indicated that luminous bacteria in
mostly sponge samples (8 out of 13) were in
the range between 104 and 105 CFU/g wet wt;
others were less than 102 CFU/ml or CFU/g
wet wt. Luminous bacteria accounted for 9.0
to 18.2% of heterotrophic bacteria in some
sponge samples (3 out of 13), while only less
than 5% of heterotrophic bacteria in the other
samples were found to be luminous.
Forty-one strains of luminous bacteria were
isolated. All of them were halophilic,
facultatively anaerobic, Gram-negative rods,
and could be identified as the family of
Vibrionaceae. According to morphological and
physiological characteristics, these isolates
were divided into six groups. The first group
had the highest similarity with
Photobacterium leiognathi (99.4%). The other
5 groups had higher than 98% similarity
with Vibrio harveyi or its closely related
species. It was found that these V. harveyi or
its closely related species and P. leiognathi
represented the entire luminous bacterial flora
in the shallow coastal waters of Taiwan during
the sampling period. The sponge-associated
luminous bacteria were predominated by
Vibrio harveyi or its closely related species.
