Abstract
1. A synthetic medium of the following ? was ? to be suited for the culture (enrichment and isolation) of marine aerobic cellulose-digesting bacteria.
NaNO3 0.5g
K2HPO4 1.0g
MgSO4. 7H2O 0.5g
FeSO4. 7H2O 0.01g
Filterd sea-water 1000.0g
Filter paper a strip (13cm×1cm) in each tube.
2. Seasonal variation of number of aerobic cellulose decomposing bacteria in sea-water (sa-mpled from Maizuru Bay) was observed.
3. Aerobic cellulose-decomposing bacteria which predominated in sea-water in different seas-ons were purely isolated and were classified into 3 species, viz., Vibrio purpureus, Vibrio pu-rpureus var, albus and Cellvibrio flavescens var. marinus, after detailed taxononical studies.
In sea-water the Vibrio predcminated in summer and the Cellvibrio outnumbered the Vibrio in the other seasons.
