    Photosynthetic bacterium (PSB) was isolated from sediment samples of Yamagawa Bay, Kagoshima, Japan. Phylogenetic analysis results of PSB isolate were closely related to <i>Rhodobacter sphaeroides</i>, purple non-sulfur photosynthetic bacteria (PNSB). Pink-colored smooth edges of single bacterial colonies were observed after 3-5 days of incubation period on Basic I medium agar plates. <i>Rhodobacter sphaeroides</i> microscopic examination showed a short rod cell (1-2 µm length) with round ends. Sediment and water samples used for ciliates cultivation were collected from Kuwano-ura Bay, Koshiki Island, Japan. Ciliates were cultivated using fish meal with radish leaves medium (MI), with sediment into MI (MII) and algae media (MIII). The use of the algae media (MIII) in cultivation mixture produced the highest total number of ciliates. Big size ciliates were identified as <i>Euplotes minuta</i> and <i>Cyclidium varibonneti</i>, while small size was identified as <i>Micrometopion nutans</i>, based on PCR-DGGE. When ciliates were cultured with the PSB isolate, <i>Rhodobacter sphaeroides</i> as a feed, ciliates grow to 2,081 individual ml<sup>-1</sup> 72 hrs later. These findings indicate that PNSB can be used to promote ciliates growth.

    Yamagawa Bay, located in Ibusuki, Kagoshima Prefecture, Japan, is a geographically enclosed coastal marine inlet, and its deteriorating seabed sediments are under an anoxic, reductive, sulfide-rich condition. In order to gain insight into diversity of anoxygenic photosynthetic bacteria (AnPBs) and their ecophysiological roles in the sediments, three approaches were adopted: isolation of AnPBs, PCR-DGGE of 16S rDNA, and PCR-DGGE of <i>pufM</i>. Among the bacterial isolates, relatives of <i>Rhodobacter sphaeroides</i> were most dominant, possibly contributing to transforming organic pollutants in the sediments. Abundance of <i>Chlorobium phaeobacteroides</i> BS1 was suggested by 16S rDNA PCR-DGGE. It could reflect intensive stratification and resultant formation of the anoxic, sulfide-rich layer in addition to extreme low-light adaptation of this strain. Diverse purple non-sulfur or sulfur bacteria as well as aerobic anoxygenic photoheterotrophs were also detected by <i>pufM</i> PCR-DGGE, which could be associated with organic or inorganic sulfur cycling. The outcome of the present study highlights ecophysiologically important roles of AnPBs in the organically polluted marine sediments.

    <p> As the basis of design method for facility scale of bubble circulation as the countermeasure for water quality preservation, simple index is theoretically investigated. Firstly, simple dynamic model for cyanobacteria is proposed based on some simple assumptions including far field horizontal density flow induced by bubble plume. Secondly, by using some assumptions, theoretical required simple index equation is derivated under steady state condition for preventing harmful cyanobacter. Finally, we analyzed required facility scale under the some parameters corresponding to actual engineering and natural conditions. The required theoretical facility scale agree with empirical value being successfully suppressing cyanobacteria in actual reservoirs in spite of some assumptions. Furthermore, the effects of some conditions such as the countermeasure managements as well as natural conditions on the facility scale are discussed. These results can provide useful scientific basis for actual dam managements of eutrophicated reservoirs.</p>

    充填塔型生物脱臭装置を適切に維持・運転するためには、装置の充填層に適切な水分と栄養塩類が維持されている必要がある。本研究では、ガス状VOC(揮発性有機化合物)を処理対象とする生物脱臭装置で供給される栄養塩成分として窒素源に着目し、栄養塩溶液を多孔性PVF(Polyvinyl formal)担体充填層に浸漬供給する装置での塩化アンモニウムの物質移動過程を、モデル浸漬実験により推定した。また、実際の生物脱臭装置における最適な浸漬条件の検索、また浸漬方式と通常装置で適用される散布方式との間での装置性能の比較を目的に、VOCガスの処理実験を行った。その結果、浸漬方式での栄養塩供給は、散布方式と比較して疎水性ガスであるトルエンの除去に有効であった。また、栄養塩溶液から充填担体への物質移動については、含水率75%を境に、高含水率側では分子拡散が、低含水率側では水分移動に伴う移流が、それぞれ主要な物質移動推進力となっていた。ただし、低含水率の充填層に対する実際の栄養塩移動量は、水分移動量から推定される移動量よりも低くなる傾向にあった。浸漬頻度を上げると充填層に過剰な菌体増殖が生じる傾向にあり、その原因は窒素源よりも水分の過剰な存在にあると推察された。過剰な菌体増殖を抑制するためには、充填層の含水率が75%を下回る程度まで乾燥してから浸漬操作を実施すべきと考えられた。(著者抄録)

    <p>　A marine raphidophyte <i>Heterosigma akashiwo</i> is a causative agent of harmful microalgal blooms, which often cause the massive mortality of aquacultured finfish. In the present study, the Pacific oyster <i>Crassostrea gigas</i> was reared with <i>H. akashiwo</i>, and effect of the microalga on filter-feeding behavior and microflora of the gastrointestinal tract was investigated. The intake of the raphidophyte cells inhibited the molluscan filter-feeding activities, suggesting the negative physiological effect of the microalgal cell contents. However, the bivalves ingested the <i>H. akashiwo</i> cells to the same extent as the diatom <i>Chaetoceros calcitrans</i>, a non-harmful indicator to estimate the filtration rate, showing a continuation of their non-selective ingestion of the phytoplankton. Microflora of the oyster soft tissue was dominated by bacteria affiliated with the family <i>Rhodobacteraceae</i>, some of which are associated with microalgae. In addition, the Bacteroidetes species, in which algicidal bacteria are included, were also found in the bivalve individuals exposed to <i>H. akashiwo</i>. These results suggested that the ingested phytoplankton affected the microbial flora in the gastrointestinal tracts, some constituents of which helped the mollusc assimilate the ingested red tide phytoplankton. This study will provide beneficial information to clarify mechanisms by which the oyster evades the ichthyotoxicity of harmful microalgae and the participation of the intestinal microorganisms in these processes.</p>

    <p>In biofiltration systems for gaseous pollutants control, appropriate range of moisture and nutritious ingredients have to be maintained in a packed bed to obtain a stable performance. In this study, mass-transfer mechanisms of ammonium chloride in the biofiltration, which treats gaseous VOCs (volatile organic compounds) and which has the packed bed of porous PVF (polyvinyl formal) irrigated by soaking, were evaluated through a simplified soaking experiment focused on nitrogen source as the key constituent. And a series of experiments on biofiltration of gaseous VOCs was carried out for the following two purposes : to specify an optimal condition of soaking-irrigation, and to compare the performance between the system with soaking-irrigation and that with trickling-irrigation which is commonly applied. Results showed that soaking-irrigation was more effective than trickling-irrigation in removal of gaseous toluene, a hydrophobic component. With regarding 75% of moisture content of packed bed as the boundary value, molecular diffusion and irrigating-water advection were dominant mass-transfer mechanisms of nutritious materials in higher and lower moisture content, respectively. However, the amount of mass-transfer of nutritious material in lower moisture content tended to be lower than that is expected by the estimation under the amount of advection with water transfer. Excess frequency of soaking-irrigation led to excess biomass growth in the packed bed, and this is possibly derived not from excess nitrogen source but from water accumulation. Soaking-irrigation had better be conducted after that moisture content of packed bed is confirmed to be below 75%.</p>

    <p>　Natural biodegradation of heavy oil in the marine environment can be accelerated by the addition of nutrients or seeding of pre-selected microorganisms. In this study, a microcosm experiment was conducted to investigate the effects of inorganic nutrient supplementation (biostimulation) and bacterial consortium amendment (bioaugmentation) on the natural degradative processes of artificially contaminated sediment. Our results revealed that the addition of nutrients had greater effect on remediation than the addition of bacterial cells. Supplementation of inorganic nutrients promoted and sustained the growth of oil-degrading and heterotrophic bacteria throughout the experimental period. Highest reduction in the total petroleum hydrocarbons, and of their components, <i>n</i>-alkanes, polycylic aromatic hydrocarbons (PAHs) and alkyl PAHs, were obtained in the biostimulated microcosms. Changes in the bacterial community were monitored by the PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) method targeting the 16S rDNA gene. Results revealed different responses of the bacterial community to the addition of heavy oil and remediation agents. Shifts in the bacterial communities in the seawater were more dynamic than in the sediment. Results of this study showed that addition of remediation agents significantly enhanced the natural biodegradation of heavy oil in a sediment-seawater microcosm trial.</p>
