  • Diverse bacteria are known to colonize plants. However, only a small fraction of that diversity has been evaluated for their biopesticide potential. To date, the criteria for sampling and selection in such bioprospecting endeavors have not been systematically evaluated in terms of the relative amount of diversity they provide for analysis. The present study aimed to enhance the success of bioprospecting efforts by increasing the diversity while removing the genotypic redundancy often present in large collections of bacteria. We developed a multivariate sampling and marker-based selection strategy that significantly increase the diversity of bacteria recovered from plants. In doing so, we quantified the effects of varying sampling intensity, media composition, incubation conditions, plant species, and soil source on the diversity of recovered isolates. Subsequent sequencing and high-throughput phenotypic analyses of a small fraction of the collected isolates revealed that this approach led to the recovery of over a dozen rare and, to date, poorly characterized genera of plant-associated bacteria with significant biopesticide activities. Overall, the sampling and selection approach described led to an approximately 5-fold improvement in efficiency and the recovery of several novel strains of bacteria with significant biopesticide potential.

  • Environmental and energy issues have always been a hot topic of global research. Oil leakage has caused great damage to the environment, affecting a wide area and it is difficult to clean up. In most cases, carbon-based adsorbents are typically utilized to remove oil spills because of their economic benefits and high adsorbent efficiency. At the same time, its excellent material properties can also be used for the preparation of supercapacitors. In this paper, the carbon aerogels were prepared by the one-step method. The prepared materials endowed a 3D network structure with a huge number of micropores and mesoporous, and the material is light-weight, stable, hydrophobic and has affinity for oil (17.02 g/g) to the KGM carbon aerogel. Through the physicchemical characterization, the KGM carbon aerogel shows specific surface area is $689m^2/g$, high water contact angle ($136.64^{\circ}$) and excellent reusability (more than 15 cycle times). In addition, we also discussed the electrochemical properties of the material and obtained the specific electrical capacity of 139 F/g under the condition of 1 A/g.

  • The purpose of the study is to investigate factors influencing the adoption of environment-friendly agriculture in greenhouse vegetable production of Jeonnam province. An interview survey were conducted during 2008, including six counties: Gwansanku of Gwangju, Gwangyang, Goheung, Damyang, Boseong, and Suncheon. Major crops grown in surveyed area were green peppers, cucumbers, strawberries, cherry tomatoes, tomatoes, and watermelons. Logit model results show that adopters of environment-friendly agriculture are more likely to participate in extensional education programs, attend educational programs on environment-friendly agriculture, have greater cultivated acreage, and have larger agriculture-only-designated farmland. However the adopters are less likely to have greater number of family members participating in farming, and live Goheung county. Efforts should be made in extensional education programs to lead more vegetable growers to adopt environment-friendly agriculture. Policy makers' additional efforts should be followed to increase adoption rate of environment-friendly agriculture in lower adopted areas.
