Various remediation methods have been applied to clean soils contaminated with pollutants. They remove contaminants from the soils by utilizing physicochemical, biological, and thermal processes and can satisfy soil remediation standards within a limited time; however, they also have an effect on the biological functions of soils by changing soil properties. In this study, changes of the biological properties of soils before and after treatment with three frequently used remediation methods-soil washing, land farming, and thermal desorption-were monitored to investigate the effects of remediation methods on soil biological functions. Total microbial number and soil enzyme activities, germination rate and growth of Brassica juncea, biomass change of Eisenia andrei were examined the effects on soil microorganisms, plant, and soil organisms, respectively. After soil washing, the germination rate of Brassica juncea increased but the above-ground growth and total microbial number decreased. Dehydrogenase activity, germination rate and above-ground growth increased in both land farming and thermal desorption treated soil. Although the growth of Eisenia andrei in thermal desorption treated soil was higher than any other treatment, it was still lower than that in non-contaminated soil. These results show that the remediation processes used to clean contaminated soil also affect soil biological functions. To utilize the cleaned soil for healthy and more value-added purposes, soil improvement and process development are needed.

국내에 자생하는 지렁이로(붉은줄지렁이)의 장에서 야생효모를 분리, 동정하고자 하였다. 지렁이는 고양시 난지 물 재생 센터에서 분양 받았으며, 지렁이 5마리에서 19개의 야생효모를 분리하였다. 효모의 D1/D2 영역으로 동정하여 국내에 보고되지 않은 효모 3균주를 선별하였다. 국내 미기록종 효모인 Yarrowia deformans YP242 (=KACC48778), Sporidiobolus pararoseus YP66(=KCTC27963), Naganishia liquefaciens YI9 (=KACC48948) 균주는 위상차현미경, API 20C AUX kit를 통해 균학적 특성을 조사하였다. YP242, YI9, YP66 균주의 세포 모양은 타원형이며, 집락은 볼록하고, 부드러운 재질을 가지는 것으로 관찰되었다. 탄소원 활성 측정 결과, YP242는 glycerol, L-arabinose, N-acetyl-D-glucosamine을, YP66는 N-acetyl-D-glucosamine을, liquefaciens YI9는 2-keto-D-gluconate을 탄소원으로 사용할 수 있음을 확인하였다.

2006년 5월부터 10월까지 국내 농생태계 49지점에서 탐색 수집된 지렁이는 3과 5속 15종 1,846 개체이며 종 구성은 다음과 같다. Amynthas agrestis 20.9%, Amynthas koreanus 20.3%, Amynthas heteropodus 15.4%, Amynthas sp. 8.7%, Drawida japonica 8.0%, Eisenia fetida 7.2%, Amynthas hilgendorfi 7.0%, Bimastos parvus 3.2%, Amynthas hupeiensis 2.5%, Aporrectodea caliginosa 1.8%, Amynthas corticis 1.8%, Aporrectodea tuberculata 1.3%, Eisenia andrei 1.2%, Amynthas sp.20.4%, Amynthas sp. 1 0.3%이다. 종 조성 비율을 보면 이와 같이 왕지렁이속, A. agrestis, A. koreanus, A. heteropodus 3종이 차지하는 개체수는 1,046개체로 전체의 약 56.7%를 차지하는 우리나라 농생태계의 우점종 이다. 성숙 개체와 미성숙 개체의 비율은 1.25:1로 성숙된 개체가 더 많이 출현하였다. Amynthas sp. 1, Amynthas sp. 2는 본 조사를 통하여 처음으로 확인되는 신종 후보로, 여러 외부형질, 특히 malepore의 형태가 지금가지 국내에서 기록된 다른 왕지렁이속에 속하는 종들과는 확연히 구별되는 특징을 갖고 있다.

An earthworm survey of Busan metropolitan area unearthed a dozen taxa in four families (including Enchytraeidae). Members of mostly common, cosmopolitan earthworm species-complexes were: Drawida cf. koreana Kobayashi, 1938, Amynthas cf. corticis (Kinberg, 1867), Aporrectodea trapezoides (Dug$\grave{e}$s, 1828) and Eisenia fetida (Savigny, 1826). Also found were Amynthas hupeiensis (Michaelsen, 1895), A. masatakae (Beddard, 1892) and Metaphire ryunome Blakemore, 2012 - the latter a new Korean record. New taxa are: moniligastrid Drawida songae yeongdo subsp. n.; megascolecid Amynthas carnosus roki subsp. n. which is compared to nominal taxon A. carnosus (Goto and Hatai, 1899) from Japan, to A. carnosus monstriferus (Kobayashi, 1936) stat. n. from Korea and to A. lichuanensis Wang and Qiu, 2005 stat. n. from China; plus lumbricid Eisenia japonica vaga subsp. n. deemed an objectively-based molecular taxon on its unique DNA COI gene barcode. Restoration of Eisenia xanthurus (Templeton, 1836) for E. andrei is mooted (in Appendix).

Earthworms have been widely used as bioindicators for soil ecotoxicity assessment. Ecotoxicity of methyl tert-butyl ether(MTBE) to terrestrial organisms were evaluated by- earthworm assay. Test earthworm species were Perionyx excavatus and Eisenia andrei. The. toxicity test was performed based on a OECD guideline No. 207 with slight modification. Mortality and abnormal morphology of earthworms exposed to different concentrations of MTBE were measured. Toxic levels of MTBE were determined by measuring the median lethal concentration (LC5O) after 72 hours. The toxicity data was statistically analyzed by Trimmed Spearman-Harbor method. This study showed that, P. excavatus is more sensitive to E. andrei, and that earthworm assay can be a good protocol to evaluate the soils contaminated gasoline components.
