上 田泰司,中 村 良一,鈴 木 譲:放 射線医 学総合研究所 海洋放射生態学研究部 茨城県那珂湊市磯崎町3609 〒311-12 Marine organism/CF/Sediment The concentration factors of 106Ru-106Rh and 137Cs for a marine bivalve and a alga were investigated. Furthermore, the transfer ratio ([cpm/g of organism] /[cpm/g of sediment]) of these nuclides from contaminated sediments to organisms was examined . Then the concent ration factors were compared with t...
Micromonas is a unicellular motile alga within the Prasinophyceae, a green algal group that is related to land plants. This picoeukaryote (<2 μm diameter) is widespread in the marine environment but is not well understood at the cellular level. Here, we examine shifts in mRNA and protein expression over the course of the day-night cycle using triplicated mid-exponential, nutrient replete cultur...
The marine brown alga Halidrys siliquosa is known to produce compounds with antifouling activity against several marine bacteria. The aim of this study was to evaluate the antimicrobial and antibiofilm activity of organic extracts obtained from the marine brown alga H. siliquosa against a focused panel of clinically relevant human pathogens commonly associated with biofilm-related infections. T...
Despite promises that 'healthy' marine systems show increased resilience, the effects of ecosystem management strategies on invasion success in marine systems is still unclear. We show that resistance to the invasive alga, Sargassum horneri, in a temperate reef system occurs through alternate mechanisms in different ecosystem states. In an old marine protected area (MPA), invasion of S. horneri...
Despite the recent interest in viruses infecting eucaryotic marine microalgae, only 7 viruses infecting marine phytoplankton have been isolated so far. It is therefore worth reviewing isolation techniques and rationalizing the method for obtaining novel microalgal viruses. I consider 7 steps as critical in the isolation procedure: (1) selection of the target host alga, (2) preparation of target...
