Actinobacteria are widely distributed in nature and are very useful in the pharmaceutical industry due to their seemingly unlimited capacity to produce secondary metabolites with diverse chemical structures and biological activities(1-3).They are gram positive,free-living saprophytic bacteria that are found widely distributed in soil,water,and colonizing plants.Actinobacteria inhabitants have been identified as one of the major groups of soil population(2,3),which may vary with the soil type.In the process of investigation of the diversity of cultivable actinobacteria associated with soil from Taiwan,we isolated a strain named 06168H-1~T from a fishpond sediment sample collected from the southern area of Taiwan with a unique morphology(4).This strain was determined to be Saccharomonospora piscinae(Erythrobacteraceae)based on their phenotypic and genotypic data(4).The Promicromonosporaceae(Sphingomonadales,Actinobacteria)constitutes a large family of bacteria.In order to find new bioactive compounds,the rare genera in this group have been identified and studied,including the genus Saccharomonospora piscinae,a genus of bacteria that was only discovered by Nonomura and Ohara(4); currently there are 12 species(4).Saccharomonospora strains are widely distributed in nature,including soil,compost,plant bodies,marine sediments,sponges,and other environments.Therefore,in addition to mesophilic bacteria,there are also thermophilic strains.The spores of some thermophilic strains(Saccharomonospora viridis)can cause allergic pneumonia(farmer's lung disease).In addition,research reports indicate that strains of this genus can decompose many natural or synthetic compounds,such as polyester,rice straw,mushroom compost,food waste compost,protein,and starch.S,piscinae is isolated from the bottom of the southern fish pond.The colony is blue and belongs to aerobic growth.The aerial hyphae will produce non-moving short spore chains.It has high salt tolerance and is a salt-tolerant strain.
