  • Isolation and application of oil-degradation microbes from the oil-contaminated soil and the determination of optimal operation conditions about the peat moss, the addition for the oil-biodegradation. After all experiments, we have acquired three important conclusions: First, we found out the 4 microbes, Pseudomonas fluorescens, Pseudomonas aeruinosa, Kurtia sp., Bacillus ceres, with excellent capability for the oil-degradation; Second, the optimal operating conditions of the peat moss for TPH treatment were pH $7{\sim}8$, temperature $25{\sim}30^{\circ}C$, water content 20%, mixing 2 times/ day, addition volume 2%; Third, in case of the application to the oil-contaminated soil with 4 mixed microbes, the removal efficiency of TPH was increased from 54% to 83% in oil-contaminated soil and from 65% to 85% in oil-contaminated soil with the peat moss.

  • Objective: This study was carried out to determine the depositional characteristics of pine needles, pine tree bark, moss, and soil, which are used as a passive air sampler (PAS) of atmospheric polychlorinated biphenyls (PCBs). Methods: All four media were sampled from the same site. PCB concentrations were analyzed by GC/MSD, and the lipid contents were measured using the gravimetric method. Results: The total PCB concentration (IUPAC No. 28, 52, 101, 138, 153, 180) was the highest in soil (227.97 pg/g dry), followed by pine needles (71.36 pg/g dry), pine tree bark (44.58 pg/g dry), then moss (21.91 pg/g dry). Pine needles contained the highest lipid contents (21.31 mg/g dry), whereas soil (10.01 mg/g dry), pine tree bark (4.85 mg/g dry), and moss (1.92 mg/g dry) contained less. The concentration of lower-chlorinated PCBs was relatively high in pine needles, pine tree bark and moss, but not in soil. The PCB concentrations were proportional to their lipid contents in pine needles, pine tree bark and moss, but a different trend was revealed in soil. Conclusions: The PCBs concentrations in the media were affected by various factors including atmospheric PCB concentrations, lipid contents, and depositional pathways. However, each of these factors had a varying influence depending on the type of medium.

  • The traditional oviposition ground for indoor breeding of Luciola lateralis is moss. This study was conducted to find the most suitable alternative oviposition ground that can maintain or increase the oviposition rate of L. lateralis while addressing the problems of larva collection time and larva loss that occur when moss is used. As alternative candidate oviposition ground comprising six colors of non-woven fabric and felt were used to measure the fecundity variation rate of L. lateralis with respect to the color and material of the oviposition ground. In addition, measure the fecundity variation rate of L. lateralis in moss, a traditional oviposition ground, was also measured and investigated for comparison. The investigation showed that the average number of eggs in the non-woven fabric group was higher than that in the felt group. The yellow non-woven fabric had an average number of eggs that was more than 100 times higher than of moss used as a traditional oviposition ground. In the space where the six color non-woven fabric were together, L. lateralis concentrated its oviposition on yellow. These results showed that yellow non-woven fabric can be sufficiently used for efficient indoor mass breeding of L. lateralis while addressing problems caused by moss, a traditional oviposition ground.

  • Growing plant in potting media without soil is known as Soilless cultivation. This method is used mostly in greenhouse cultivation to increase horticultural commodities production. Peat moss is commonly utilized as potting media substrate because of its characteristic. However, peat moss price is high because of the quantity of peat moss in nature has been decreased. Recently, most of the research is conducted to find the alternative growing medium to cultivate horticulture plant in potting media. Perlite and rice husk ash were mentioned that had a potent as alternative growing media for seasonal plants to increase agriculture production due to the lack of production area. This study aimed to determine the effect of using different substrate and growth performance of chili. The method used was the soilless cultivation. The chili was planted in the pot with perlite media, rice husk ash media, and peat moss media. The chili was measured after 65 days after planting. The result showed that rice husk ash and perlite were more potentials in chili growth performance than peat moss. Rice husk ash had the significant result of plant height. While, Perlite effect on root length, plant weight, leaf length, and stem diameter. The best alternative for cultivation chili without substrate based on this research was perlite then rice husk ash and peat moss.

  • 수출용 접목선인장 '황월'의 기존에 사용되는 배지인 피트모스 보다 가격이 낮으며, 생육이 피트모스와 비슷한 배지를 선발하고자 7가지 종류 배지 (피트모스, 배양토 BM6, 코코피트, 하이드로크레이, 하이드로볼, 휴가토, 버미큘라이트)에 재배하여 배지의 이화학적 성분과 생육변화를 조사하였다. 배지의 이화학적 분석결과로는 코코피트가 식재 90일 후에도 이화학적 성분의 변화가 거의 없어 안정적이었으며, 하이드로볼이 보수력이 높은 것으로 조사되었다. 수출용 접목선인장 '황월'의 생육조사 결과 유기질 배지에서 대조구인 피트모스와 비슷한 생육을 보인 배지는 코코피트 였으며, 무기질 배지에서는 휴가토, 버미큘라이트, 하이드로클레이가 대체적으로 양호한 생육을 보였다. 그러나 무기질 배지는 무게가 가벼워 식물식재 후 이동 시 쓰러지는 단점이 있었다. 피트모스와 비슷한 생육조건과 낮은 가격을 가진 배지로는 유기질 배지인 코코피트와 수태를 감싸지 않고 사용할 수 있는 무기질 배지인 무게가 상대적으로 무겁고 값이 낮으며 국내 생산이 되는 하이드로볼이 수출용 선인장 재배 배지로 적합할 것으로 판단되었다.

  • This study evaluates the microbial safety of ginseng sprouts packaged in moss and a modified atmosphere (MA) film within Styrofoam boxes. Ginseng sprout samples were stored at 4℃ for seven days, and the total fungi and aerobic bacteria counts, relative humidity, and moisture content were measured at 0, 1, 3, 5, and 7 days. During the storage period, both packaging treatments caused an increase in the total fungi and aerobic bacteria counts. However, by the seventh day, the ginseng sprouts packaged in the MA film demonstrated significantly lower counts of total fungi (3.03 log CFU/g) and aerobic bacteria (7.32 log CFU/g) than those in moss (3.66 and 7.63 log CFU/g, respectively). Moss packaging alone resulted in the total fungi count reaching up to 3.36 log CFU/g, with the aerobic bacteria count consistently exceeding 7 log CFU/g, highlighting the importance of hygienic management. Moreover, no significant differences were observed in the moisture content and relative humidity between the MA-film- and moss-packaged groups throughout storage. These findings indicate that the functional MA film is a more hygienic packaging solution for ginseng sprouts than moss.

  • 농가현장에서 이끼재배에 활용할 수 있는 기존의 연구자료가 거의 없는 실정에서 분화식물로서 관상가치가 높은 나무이끼의 재배기술을 개발하고자 투명용기 재배시 토양 습도, 적정 공기노출 정도구명, 적정 용토 구명, 지피용 이끼선발 등 상품화에 관한 연구를 수행하였다. 나무이끼의 투명용기 재배시 용기내에 수분을 적습(수분 60~80%)으로 관리하는 것이 좋으며 용토는 피트모스:펄라이트(7:3)의 상토에서 좋았고 공기노출 정도에 있어서는 완전밀폐와 10% 노출에서 생육이 좋았다. 용기의 공기유통 정도를 나타내는 천공형태는 상부천공 2구에서 생육이 좋고 내부에 습기가 맺히지 않았다. 투명 용기내의 적정 용토는 수태, 피트모스, 피트모스+펄라이트 구에서 생육이 좋았으나 수태는 가격이 비싸 경제성이 떨어지므로 피트모스나 피트모스+펄라이트 상토가 유리한 것으로 나타났다. 나무이끼와 어울릴 수 있는 지피용 이끼로는 솔이끼, 편평털깃털이끼, 깃털이끼, 털깃털이끼, 아기초롱이끼, 은이끼, 가는털깃털이끼, 표주박이끼, 흰털이끼, 꼬마이끼 등 10종 모두 초장이 0.7~2.7 cm로 나무이끼보다 1 cm이상 작아 지피용으로 적당한 것으로 나타났다.

  • The objective of this study was to discuss the characteristics of the moss flora of Mt. Deogyu located on the border of the Jeonbuk and Kyungnam provinces in Korea. A total of 21 field surveys were carried out at various sites in the mountain area from August 2007 to September 2008. All the collected materials were processed into voucher specimens and were currently deposited in the herbarium at Chonbuk National University (JNU). In this study, we collected and identified 158 moss taxa, which included 156 species, 1 subsp. and 1 var. of 96 genera and 37 families. Unconfirmed taxa in this study, but previously recorded, belonged to 25 taxa, which included 13 families, 19 genera and 25 species. In addition, 183 taxa were found on Mt. Dreogyu, which belonged to 37 families, 101 genera, 1 subsp. and 1 var. The habitat of each collection was examined and the classification system of Ignatov et al. (2006) was used. New vernacular names of 6 families and 11 genera were then determined. Six species, formerly thought be only in North Korea, were shown to be present on Mt. Deogyu, which included Bucklandiella laeta, Anomobryum filiforme var. concinnatum, Herzogiella turfacea, Brachythecium rutabulum, Eurhynchium angustirete and Campylidium hispidulum.
