抄録	Acid mine drainage (AMD) is acidic and generally enriched with iron, aluminum, sulfate and heavy metals, such as lead and cadmium. AMD is a growing problem of emerging concern that cause detrimental effects to the environment and living organisms. Yanahara mine in Misaki Town, Okayama, Japan, had mainly produced pyrite for sulfuric acid manufacture. Although it was closed in 1991, AMD is being generated from the mine now. A passive treatment based on the biological oxidation of ferrous iron is a promising strategy for AMD remediation. AMD from Yanahara mine is treated in a plant using iron-oxidizing bacteria, Acidithiobacillus ferrooxidans and Ferrovum spp. The AMD generation continues for several centuries with dramatic consequences on the receiving environments. Therefore, the development of sustainable and cost effective treatment process is required. A development of the effective biological treatment process with an iron oxidation reactor operated at pH 3.5 is described in this report. Economic aspects are also discussed.

抄録	The objectives of this study were to (i) determine the optimum number of whole leaves to retain on a tomato plant for effective blossom-end rot (BER) management and (ii) explore the relationship between shoot calcium (Ca) and fruit Ca in non-defoliated plants in two different sized fruit cultivars, a large-fruited cultivar ‘Momotaro fight’ and a medium-fruited cultivar ‘Cindy sweet’. Treatments involved maintaining 18, 15 and 12 leaves on a plant. All lateral shoots were removed regularly throughout the growing period except the shoot closest to the flowering truss in the 18-leaf treatment. At the length of 10cm, these shoots were sampled for real time Ca determination using a hand held Ca2+ meter. In the plants defoliated to 18 leaves, BER was higher in ‘Momotaro fight’ at 10% compared to 2% in ‘Cindy sweet’. Fruit growth rate was significantly increased by defoliation in ‘Momotaro fight’, however no significant difference was observed among treatments in ‘Cindy sweet’. Defoliating to 12 leaves increased daily Ca transport rate by 59% and 37% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. Defoliating to 12 leaves increased the water-soluble Ca concentration in the distal part of fruit by 34% and 14% in ‘Momotaro fight’ and ‘Cindy sweet’, respectively. In the plants defoliated to 18 leaves where only old yellowish leaves were removed, a significant steady decrease was observed in the concentration of water soluble Ca in the distal part of fruit with increase in truss order. There was a significant linear relationship between water-soluble Ca concentration in the distal part of the fruit and Ca concentration in the lateral shoot of plants defoliated to 18 leaves. We conclude that under moderate water stress by root zone restriction and also certain other BER inductive conditions, defoliation to 12–15 leaves on a tomato plant should be a promising approach for decreasing BER incidence in susceptible large fruit cultivars.

抄録	The field study was conducted in Nam Dong district, Thua Thien Hue province, Vietnam during May 2019 to observe the effects of SRI method on the rice yield and eradicate the factor affecting the yield. The study was carried out to evaluate the agronomic characteristics of rice, fresh and dry matter production, soil characteristics with a focus group discussion regarding cultivation by SRI and non-SRI methods. The soil analyses using standard measurements showed quite similar soil fertility in both SRI and non-SRI methods, while rice plants showed good agronomic performances and fresh and dry matter production in SRI method. At harvesting time, the yield and yield potentials of rice were greater in SRI than that in non-SRI methods. Focus group discussion found some factors that limited SRI development in Nam Dong district.

酵母2μプラスミドのコピー数変動の数理的解析

タイトル（別表記）	Mathematical analysis of copy number variation of 2 μ-based plasmids in yeast cells
フルテキストURL	srfa_109_007_011.pdf
著者	佐伯望\| 守屋央朗\|
抄録	Plasmids with the 2 μ plasmid origin are commonly-used in the genetic engineering of the budding yeast Saccharomyces cerevisiae. Intracellular copy numbers of 2 μ plasmids are different depending on the genes inserted into the plasmids. This difference is thought to occur from the difference in the growth efficiency （fitness） produced by the positive- and negative-selection biases of genes inserted in the plasmid. In this study, we made a mathematical model based on this assumption. Computational simulations of the model validated that copy numbers of the plasmids are rapidly settled depending on the fitness created by the gene on the plasmid. The copy number of a plasmid only contains a bias to keep the plasmid in a single copy became average 20copies per cell when the plasmid is randomly distributed, suggesting that no positive distribution mechanism is required for a plasmid to become multicopy.

抄録	Novel glycine oxidase (GlyOX) from Marinomonas mediterranea depends on cysteine tryptophilquinone (CTQ) and catalyzes the oxidative deamination of glycine to produce a glyoxylate, ammonia, and hydrogen peroxide. M. mediterranea GlyOX genes (goxA and goxB) were cloned and recombinant GlyOX was heterologously expressed by E. coli. The purification of recombinant GlyOX was carried out by metal affinity and DEAE-Toyopearl 650M column chromatographies. M. mediterranea GlyOX was homotetramic with a molecular mass of 76kDa and showed optimum activity around 30°C and at pH 5.0, and stability below 50°C and between pH 5.0 to 9.0. M. mediterranea GlyOX shows a strict substrate specificity toward glycine, and the Michaelis constant for glycine was 0.5mM. M. mediterranea GlyOX could determine the quantity of glycine in human serum and human blood plasma with high sensitivity. This study revealed the catalytic and structural properties of M. mediterranea GlyOX with high substrate specificity.
