The production of transparent exopolymer particles (TEP) by four diatoms, Coscinodiscus granii, Eucampia zodiacus, Rhizosolenia setigera, and Skeletonema sp., was examined. Most of the TEP in C. granii (74% of the maximum) were produced during the growth phase. In contrast, most of the TEP in E. zodiacus (73%), R. setigera (74%), and Skeletonema sp. (70%)(More)
The combined antimicrobial effects of hop resins with sodium hexametaphosphate, glycerol monocaprate, and lysozyme were investigated aiming to make an effective agent against Escherichia coli. When they are used separately, the antimicrobial activity against E. coli was minimal. However, the combination of hop resins with sodium hexametaphosphate exhibited(More)
In the autumn of 2007, marine mucilage caused by the diatom Coscinodiscus granii occurred in the central area of Ariake Sound, Japan, and resulted in damage to fishery. To elucidate the mechanism underlying the outbreak of marine mucilage, we examined the effect of temperature on cell growth and production of transparent exopolymer particles (TEPs) in a(More)
Concomitant with the bloom of a diatom, Coscinodiscus sp., there was a sudden production of mucilage in the central area of Ariake Sound during the autumn of 2007. To obtain basic information about this marine mucilage and identify the causative organism, we have examined the morphological characteristics of Coscinodiscus sp. and the production of(More)
Local footpad infection in mouse was investigated with 55 clinically isolated strains of Staphylococcus aureus. When 10(7) viable cells were inoculated into the footpad, local swelling and bacterial growth resulted after 24 hr. With a dose of 10(6) cells, moderate swelling was observed after a few hours but the reaction had almost disappeared after 24 hr.(More)
