축산폐수에서 분리된 세균 S. sp1(S. capitis)와 S. sp2(3. xylosus)를 이용한 축산폐수 중 질소화합물 분해정도를 파악한 결과 1) 증식에 알맞은 조건은 LB broth, $27^{\circ}C$, pH7로 나타났다. 2) S. sp1은 배양 7일 초기 농도의 90.3%, 7일째 32.9%로 감소되어 14일까지 다소 증가하면서 유지되었다. 3) S. sp1과 S. sp2를 혼합배양한 결과 S. sp1과 S. sp2 단독배양보다 분해 효율이 높고 기간도 2일정도 단축되었다.

Parasites of wild animals are closely related with parasites of domestic animals. Wild animals take charge of an important role at parasitic infestation of domestic animals because of unrestrained movement. The authors carried out the work of actual condition of parasitic infestation on wild animals, total 1,014 cases, in the Korean Zoo. The results are summarized as follows: 1. Total rate of parasitic infestation was 36.1% with infestation of 366 among 1,014 cases. The rate of single infestation was 32.6% with infestation of 331 cases, double infestation 3.1% with 31 cases, triple infestation 0.2% with 2 cases and quadrople infestation 0.2% with 2 cases. 2.

The extremely halophilic archaebacterium Haloarcular sp. EH-1 was isolated from solar salts. Haloarcular sp. EH-1 accumulated poly(3-hydroxyalkanoate) (PHA) as intracellular granules. PHA production in batch culture have been studied. The PHA was identified as poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHB/HV) of 3-hydroxybutyric acid and 3-hydroxyvaleric acid by the analysis of GC, IR and NMR. The melting temperature of PHB/HV was 152.46$^{\circ}C$, viscosity was 1.25 ㎗/g, and molecular weight was $1.44 X 10^5.$

In this study, aniline dioxygenase genes responsible for initial catabolism of aniline in Burkholderia sp. HY1 and Delftia sp. HY99 were cloned and the amino acid sequences were comparatively analyzed, which already have been reported as bacteria utilizing aniline as a sole source of carbon and nitrogen, B. sp. HY1 was found to have at least a plasmid, and the plasmld-cured strain, B. sp. HY1-PC obtained using mitomycin C was tested with wild type strain to investigate whether the former maintained the degradability for aniline. This proved that the aniline oxygenase gene from B. sp. HY1 was located in chromosomal DNA, not in plasmid DNA. Aniline dioxygenase small subunits from B. sp. HY1 and D. sp. HY99 were found, based on 146 amino acids, to share 79% similarity. Notably, ado2 genes from B. sp. HY1 and D. sp. HY99 which were found to be terminal dioxygenase of aniline dioxygenase small subunit showed 99% similarity in the deduced amino acid sequences with tdnA2 of Frateuria sp. ANA-18 and danA2 of D. sp. AN3, respectively. Besides, enzyme assay and amino acid sequence analysis of catechol dioxygenase supported the previous report that B. sp. HY1 might occupy ortho-cleavage pathway using catechol 1,2-dioxygenase, while D. sp. HY99 might occupy catechol 2,3-dioxygenase for meta-cleavage pathway.

Objectives : This research ws performed to investigate the effect of manual acupuncture at TE4, SP3 and TE4+SP3 on body weight, blood glucose, BUN, creatinine, lipid metabolism, liver function and morphological change of hepatic tissue in hyperglycemia rats. Methods : Experimenal groups were divided into hyperglycemia group(Control group), hyperglycemia and acupuncture therapy group at SP3, hyperglycemia and acupuncture therapy group at TE4, hyperglycemia and acupuncture therapy group at TE4+SP3 , once per 2 days during 5 weeks. Results : Body weight was decreased significantly in TE4 group of fifth week compared with Control group. Blood glucose was decreased significantly in SP3 group compared with control group. Creatinine was decreased significantly in TE4 and TE4+SP3 group compared with control group. Total cholesterol was decreased significantly in TE4+SP3 group compared with control group. Triglyceride was decreased significantly in TE4 gorup compared with control group. In the morphological change of hepatic cell, TE4 and SP3 group were showed he rough endoplasmic reticulum forms aggregates of parallel, flattened cisternae scattered randomly throughout the cytoplasm compared with control gruop. Conclusions : Acupuncture at TE4 can manage hyperglycemia by controlling body weight, and lipid metabolism in hyperglycemia rats induced by streptozotocin.

Gas formation, and container swelling and explosion during the distribution of commercial soy sauce is an important problem to be solved. Six yeasts were isolated from soy sauce returned because of container swelling. Three isolates (SS-1, SS-2, SP-1) formed film on soy sauce while others did not. Five isolates(SS-1, SS-2, SS-4, SP-1, SP-2) actively fermented soy sauce to produce gas and all were identified as Zygosaccharomyces rouxii, and one other isolate (SS-3) fermented soy sauce very weakly and was identified as Candida globosa.

This paper describes six new species of sponges in the genus Agelas from Kosrae Island, The Federated States of Micronesia. Most Agelasid sponges are known from only tropical regions. All the new Agelas species; A. fragum n. sp., A. kosrae n. sp., A. purpurea n. sp., A. bakusi n. sp., A. vansoesti n. sp. and A. incrustans n. sp. are compared with other valid species that were studied. Six new species differ from the other species by morphology, growth form, skeletal fibres, habitats and spicule size. Agelas fragum n. sp. is characterized by its tuberculate surface and primary fibres with brush-like spicules. Agelas kosrae n. sp. is differs in skeletal structure and have tertiary fibres. Agelas purpurea n. sp. is characterized by primary, secondary and tertiary fibres are all cored with spicules. Agelas bakusi n. sp. is similar to Agelas clathrodes in shape, but differs in the primary fibres. Agelas vansoesti n. sp. is characterized by having acanthostrongyles. Agelas incrustans n. sp. is distinguished by its encrusting and not cavernous interior.

Larvae of fishes were collected at 26 stations in the Korea Strait, by horizontal towings using the fish larval net (Norpac) in the surface layer and by oblique towings using Isaac-Kid mid-water trawl in the mid-water layer in summer (July) and in autumn (November), in 1983. The towing speed was 1.5 knots. Of the larval fish examined, 3,529 individuals were identified to generic and specific levels. They belong to 27 families, consisting of 38 species in 37 genera. Unidentified were 114 specimens. The most abundant species was Engraulis japonica which occupied $88.5\%$ of the whole 3,645 individuals. Diaphus sp. took the second place with 50 individuals ($l.3\%$). Seasonally abundant species were in the order of Engraulis japonica, a Gobid, Trichiurus lepturus, and Diaphus sp. in summer, and in the order of Diaphus sp., Engraxlis japonica, Bothus sp., and a Ophichthid in autumn. Of these larvae, Engraulis japonica and Diaphus sp. continuously appeared from summer to Autumn. Champsodon sp., Diaphus sp. and Synagrops philippinensis were unrecorded species in Korea.

BACKGROUND: Recent studies have described the importance of bacteria that can degrade polycyclic aromatic hydrocarbons (PAHs). Here we screened bacterial isolates from commercial gasoline for PAH degraders and characterized their ability to degrade PAHs, lipids and proteins as well as their enantioselective epoxide hydrolase activity, salt tolerance, and seawater survival. METHODS AND RESULTS: One hundred two bacteria isolates from commercial gasoline were screened for PAH degraders by adding selected PAHs on to the surface of agar plates by the sublimation method. A clear zone was found only around the colonies of PAH degraders, which accounted for 13 isolates. These were identified as belonging to Bacillus sp., Brevibacterium sp., Micrococcus sp., Corynebacterium sp., Arthrobacter sp., and Gordonia sp. based on 16S rRNA sequences. Six isolates belonging to Corynebacterium sp., 3 of Micrococcus sp., Arthrobacter sp. S49, and Gordonia sp. H37 were lipid degraders. Arthrobacter sp. S49 was the only isolate showing high proteolytic activity. Among the PAH-degrading bacteria, Arthrobacter sp. S49, Brevibacterium sp. S47, Corynebacterium sp. SK20, and Gordonia sp. H37 showed enantioselective epoxide hydrolase activity with biocatalytic resolution of racemic styrene oxide. Among these, highest enantioselective hydrolysis activity was seen in Gordonia sp. H37. An intrinsic resistance to kanamycin was observed in most of the isolates and Corynebacterium sp. SK20 showed resistance to additional antibiotics such as tetracycline, ampicillin, and penicillin. CONCLUSION: Of the 13 PAH-degraders isolated from commercial gasoline, Arthrobacter sp. S49 showed the highest lipid and protein degrading activity along with high active epoxide hydrolase activity, which was the highest in Gordonia sp. H37. Our results suggest that bacteria from commercial gasoline may have the potential to degrade PAHs, lipids, and proteins, and may possess enantioselective epoxide hydrolase activity, high salt tolerance, and growth potential in seawater.
