Predicting soil water movement in converted soybean fields under high moisture condition
Crops adapt to variable soil moisture by varying the distribution of their roots and patterns of water absorption. Meanwhile, proper numerical model for predicting soil moisture in croplands especially under h...

Macropores regulate CO2 behavior in an andisol soil
Macropores resulting from soil pedogenesis, biological activity, and agricultural practices play important roles in soil water, chemical and gas transport; however, seldom studies focus on the effect of soil m...

Open AccessEfficient production and secretion of oxaloacetate from Halomonas sp. KM-1 under aerobic conditions
The alkaliphilic, halophilic bacterium Halomonas sp. KM-1 can utilize glucose for the intracellular storage of the bioplastic poly-(R)-3-hydroxybutyric acid (PHB) and extracellular secretion of pyruvate under aer...

Predicting soil moisture condition in arbitrary agricultural lands using the digital soil map and soil physical properties database
To predict soil moisture condition in arbitral agricultural lands by taking spatial distribution of soil type in a watershed into account, we investigated the possible proper methods of determining the soil hy...

Open AccessEfficient production and secretion of pyruvate from Halomonas sp. KM-1 under aerobic conditions
The alkaliphilic, halophilic bacterium Halomonas sp. KM-1 can utilize both hexose and pentose sugars for the intracellular storage of bioplastic poly-(R)-3-hydroxybutyric acid (PHB) under aerobic conditions. In t...

Behavior of carbon dioxide in soils affected by tillage systems
Agricultural management plays an important role in the storage of carbon in soils. The behavior of soil CO2 in an Andisol in two different tillage systems (no tillage and tillage) was studied. Soil-column incubat...

Phyto-purification of livestock-derived organic waste by forage rice under subtropical climate
Soil and water pollution caused by organic waste is a concern for livestock-breeding areas. Nitrogen balance in a paddy-field water-purifying system in which cattle feces were applied was studied for 4 years t...

Micro paddy lysimeter for monitoring solute transport in paddy environment
The micro paddy lysimeter (MPL) was developed and evaluated for its performance to simulate solute transport in paddy environment under laboratory conditions. MPLs were constructed using soil collected from Fi...

Anaerobic growth of Corynebacterium glutamicum using nitrate as a terminal electron acceptor
Corynebacterium glutamicum, a gram-positive soil bacterium, has been regarded as an aerobe because its growth by fermentative catabolism or by anaerobic respiration has, to this date, not been demonstrated. In th...

Efficient induction of formate hydrogen lyase of aerobically grown Escherichia coli in a three-step biohydrogen production process
A three-step biohydrogen production process characterized by efficient anaerobic induction of the formate hydrogen lyase (FHL) of aerobically grown Escherichia coli was established. Using E. coli strain SR13 (fhl...

Enhanced hydrogen production from glucose using ldh- and frd-inactivated Escherichiacoli strains
We improved the hydrogen yield from glucose using a genetically modified Escherichia coli. E. coli strain SR15 (ΔldhA, ΔfrdBC), in which glucose metabolism was directed to pyruvate formate lyase (PFL), was constr...

The development of a coupled model (PCPF-SWMS) to simulate water flow and pollutant transport in Japanese paddy fields
A new coupled model (PCPF–SWMS) was developed for simulating fate and behavior of pollutant in paddy water and paddy soil. The model coupled the PCPF-1, a lumped model simulating pesticide concentrations in pa...
