Phytochemical investigation of the sesame dregs of Sesamum indicum was conducted by open column and prep-HPLC chromatography. Two phytosterols (1 and 2) and two lignans (3 and 4) were isolated from the MeOH extracts of sesame dregs, and identified as ${\beta}$-sitosterol (1), daucosterol (2), sesamin (3), and sesamolin (4) by spectral analysis. Although these compounds were already isolated from sesame, it is important that they were still main phytochemical components in the sesame dregs.

A study on the screening and isolation of microorganism was performed for the removal of main malodor, such as ammonia, produced from the livestock farm. The main malodor components in livestock farm are ammonia, volatile fatty acids, sulfur compounds and trimethylamine. Damages to man and livestock were originated from malodors mainly due to ammonia, and thus ammonia reduction experiments were performed. Sludge of sewage treatment plant was inoculated in the sesame dregs culture, from which ammonia gas was produced. An aerobically grown, pure cultured isolated from the 10th enrichment culture was analyzed by 16S rRNA sequencing and identified as Alcaligenes sp. NS-1. This strain NS-1 precultured in the sesame dregs was found to remove ammonia gas with an efficiency of approximately 99-100% at an average concentration of 40 ppmv of ammonia gas. When the strain NS-1 sprayed to pig excrements, the removal efficiency at an average concentration of 100 ppmv of ammonia was approximately 60% after 16 hr.

참기름의 변조 여부를 쉽게 판별하고, 변조에 사용된 혼입유의 실태를 파악할 수 있는 방법으로써 FV(Fatty acid ratio & villavecchia reaction) value를 상요하였다. FV value 는 gas chromtography로 지방산 조성을 분석하여 C18: 1 + C18 : 2/C16 : $0{\times}C18$ : 3값을 구하고 이 값에 modified cilavecchia -suarez test(MVTV)에서 얻어진 값을 곱하여 결정하였다. 이 FV value를 이용하여 전남 지방 시장등지에서 구입한 참기름 총 74건에 대해 그 순도를 판별하고 변조에 사용된 혼입유의 실태를 파악하였다. 수거된 참기름들에 대해 FV value 로 산출한 결과 총 74건 중 11건만이 순수한 참기름으로 추정되어졌다. 변조에 상용된 혼입유의 실태를 산출된 FV value로 추정한 결과 대두유 혼입이 23건으로 가장 많았으며, 그밖에 미강유 혼입 및 깻묵을 유기용매로 재 추출한 참기름이 각각 10건, 들깨유 혼입이 8건, 옥수수유 혼입이 7건, 면실유 혼입이 3건, 채종유 혼입이 2건 등이었다.

Agrochemicals for the plant-disease control are criticized severely for causing environmental pollution and residual problems, and consequently microbial disease control agents are expected to be safer and more economical for sustainable agriculture. Treatment of biological control agents to seed requires the use of effective delivery systems that allow full expression of the benefical qualities of the bioprotectant. For the activation and establishment of bioprotectant around the plant seed which are able protect the seeds and seedlings from pathogen attack, the optimal liquid coating formulation was obtained using 2% sodium carboxymethyl cellulose (binder), 20% sesame dregs (solid particulate material), and dried spore of Bacillus subtilis YBL-7 (bioprotectants, 10 mg/g of seed). Suppressive of root rot was demonstrated in pot trials with coated kidney bean (Phaseolus vulgaris L.) seeds. Coated seeds with B. subtilis YBL-7 spore in F. solani-infested soil reduced disease incidence by 85% to 90% after 30 days.
