An auxin-producing bacteria (A-1) was isolated from soils of Oyster mushroom farmhouse in Daejeon city, South Korea. The strain A-1 was classified as a novel strain of Ochrobactrum anthropi based on a chemotaxanomic and phylogenetic analyses. The isolate was confirmed to produce indole-3-acetic acid (IAA), one of auxin hormones, by TLC and HPLC analyses. The maximum concentration of IAA, 5.6 mg L-1 was detected from the culture broth of O. anthropi A-1 incubated for 24 h at 35oC in R2A broth containing 0.1% L-tryptophan. To investigate the growth-promoting effects to the crops, the culture broth of O. anthropi A-1 was inoculated to water cultures and seed pots of mung bean as well as lettuce. In consequence, the adventitious root induction and root growth of mung bean and lettuce were 2.7 and 1.4 times higher than those of the non-inoculated, respectively.

The purpose of this study is to present the results as basic data for establishing proper storage conditions and distribution conditions of actual farms at point of increasing concern about hygiene and palatabiltiy of consumers to food. In this study, three farmhouses of dried persimmons prepared using different storage conditions were selected in Sangju (Korea). The dried persimmons were stored for 90 days. Changes in temperature and humidity were measured with a temperature and humidity recorder under each storage condition, and physicochemical analysis and sensory evaluation were performed. The average temperatures of farmhouse A, B and C were approximately -22--23℃, -19--18℃ and -25℃ respectively. The humidities of A, B and C were 62-63%, 59-60%, and 66-67%, respectively, and the moisture contents of all farmhouses increased during the storage period, with farmhouse B showing the most rapid increase. Free sugars increased, except for those from farmhouse C. Persimmons from farmhouse B showed the greatest changes in chewiness and hardness. The values of a* and b* were significantly decreased in persimmons from farmhouse B, and the color difference value of farmhouse B was dramatically increased. Sensory evaluation showed that the color preference tended to decrease compared with the initial value. Only farmhouse B showed decreased overall acceptability. Moreover, farmhouse B had the highest storage temperature and lowest humidity. Therefore, our results showed that storage at a low temperature and high humidity was important for manufacturing high-quality dried persimmons.

This study was carried out to obtain the optimal ammonia removal efficiency using pyroligenous liquid for the economical and environment-friendly odor removal at a petty livestock farmhouse. The ammonia removal efficiencies were evaluated due to changing dilution rates(×10, ×20, ×30, ×50 and ×100 times) and different spray amounts(10㎖ and 20㎖) of pyroligenous liquid. The wet scrubber device was used to remove odor in closed-type livestock farmhouse. According to dilution rate of the pyroligenous liquid, the optimum rate was 20 times and the removal efficiency increased by decreasing dilution rates. In the case of spray amounts with the optimum dilution, the amount was 20 ㎖ and the removal efficiency increased by increasing spray amount. Also, the removal efficiency by using wet deodorizing device was 83.0～97.0% with 20 times diluted liquid.
