Effect of ethanol treatment on morphological and technical properties of corn starch
As a result, starch treated by solvent with different concentrations tended to form wrinkles and pore from the surface to the inside of the starch granules during ethanol immersion. Therefore, the oil and water holding capacity, solubility, swelling and viscosity of the solvent-treated starch samples increase as the concentration of ethanol increases.

Production of bacterial cellulose films by gluconoacetobacter xylinus for lipase immobilization
Results showed that increasing in rotational speed from 0 rpm to 200 rpm converted cellulose-producing cells to non-cellulose-producing ones, leading to a significant decline in BC film formation. The increase in initial inoculum size from 0.01 g/L to 0.1 g/L reduced sugar concentration and surface area of the medium, and therefore inhibiting the formation of film-like cellulosic biomass.

An investigation of upland soil fertility from different soil types
Soil type is a vital determinant of soil fertility because of its characteristic biological, chemical, and physical properties. However, the soil fertility of upland soil is probably changed by different agricultural management practices regardless of soil type. This study investigated the features of soil fertility (bacterial biomass, total carbon (TC), and total nitrogen (TN)) in upland fields in Japan. One thousand soil samples from different soil types were collected from upland fields located on 36 prefectures in Japan.

Residual feed intake: A limiting economic factor for selection in poultry breeding programs
This review provides new insight into the RFI and its relationship with productive traits in different species of poultry. In poultry breeding programs, use of the RFI in selection procedures as a negative trait must be adopted to produce an efficient breed with low feed costs and high productivity. From the point of view of an environmental perspective, selecting birds with lower RFI reduces emissions of ammonia and greenhouse gases from poultry houses.

Interseeding of ruzigrass into soybean: Strategies to improve forage cultivation in no-till systems
The present study hypothesized that ruzigrass seed treatment and sowing density and period influence seed germination and seedling establishment and that physical and/or allelopathic effects of the leaves and petioles of soybean cultivars are a major factor for interseeding success. To test these hypotheses, the influences of seed treatment, sowing density, time, and soybean cultivar on the emergence of ruzigrass seedlings in a soybean interseeding system were evaluated with the aim of mitigating environmental effects in the establishment of forage in succession to soybean.
