  • Two porcellanid crabs collected from Jeju Island, Petrolisthes militaris (Heller, 1862) and P. coccineus (Owen, 1839) are recorded as new to Korean fauna. Hence, the Korean porcellanid crabs consist of nine species of seven genera and the genus Petrolisthes now contains three described species.

  • Basic studies on the cultural characteristics of Pycnoporus coccineus and P. cinnabarinus were performed. They exhibited $30{\sim}40{\circ}C$ optimal temperature ranges and optimal pH ranges of $5{\sim}6$. Among 6 media, they were good at mycelial growths on PDA, LBA and YMA.P. coccineus grew more than P.cinnabarinus on the same medium. Among 10 sawdust media, they were good at mycelial growth on three oak trees and Alnus hirsuta. However, the sawdust of Castanea crenata was bad at mycelial growth. Among 3 coniferous trees, Larix leptolepis showed better growth than the other trees such as Pinus densiflora and P. koraiensis. The fruit body production P. coccineus was about twice better than P. cinnabarinus on Quercus spp. sawdust cultivation.

  • Seven white rot fungi (Irpex lactenis, Coriolus hirsutus, Lopharia mirabilis, Schizopora paradoxa, Ganoderma lucidum, Pleurotus ostreatus and Pycnoporus coccineus) native to Korea and two famous exotic lignin degradable white rot fungi (Coriolus versicolor and Phanerochaete chrysosporium) were investigated to clarify their physiological and physicochemical characteristics on white-rotted wood blocks. G. lucidum degraded wood blocks more seriously than those by exotic lignin-degrading fungi, C. versicolor and P. chrysosporium, but only slightly decreasecl the strength of wood which was compared to the weight loss, persumably on the account of its small use of cellulose when attacking wood. It is quite interesting to note that the holocellulose degradation rate of G. lucidum was also higher than any of the other tested fungi. The order of fungi, according to the lignin-decomposing rates, was G. lucidum>P. coccineus>C. versicolor>S. paradoxa>P. chrysosporium>L. mirabilis>P. ostreatus>C. hirsutus>I. lactenis. The lignin degradation of G. lucidum and P. coccineus which were collected in Korea was greater than that of C. versicolor and P. chrysosporium. If holocellulose degradation is not considered. G. lcidum has the merit of actual application in biomass conversion due to linin removal.

  • This study was conducted to evaluate the degradation of aromatic dyes and the production of ligninolytic enzymes by 10 white rot fungi. The results of this study revealed that Pycnoporus cinnabarinus, Pleurotus pulmonarius, Ganoderma lucidum, Trametes suaveolens, Stereum ostrea and Fomes fomentarius have the ability to efficiently degrade congo red on solid media. However, malachite green inhibited the mycelial growth of these organisms. Therefore, they did not effectively decolorize malachite green on solid media. However, P. cinnabarinus and P. pulmonarius were able to effectively decolorize malachite green on solid media. T. suaveolens and F. rosea decolorized methylene blue more effectively than any of the other fungi evaluated in this study. In liquid culture, G. lucidum, P. cinnabarinus, Naematoloma fasciculare and Pycnoporus coccineus were found to have a greater ability to decolorize congo red. In addition, P. cinnabarinus, G lucidum and T. suaveolens decolorized methylene blue in liquid media more effectively than any of the other organisms evaluated in this study. Only F. fomentarius was able to decolorize malachite green in liquid media, and its ability to do so was limited. To investigate the production of ligninolytic enzymes in media containing aromatic compounds, fungi were cultured in naphthalene supple mented liquid media. P. coccineus, Coriolus versicolor and P. cinnabarinus were found to produce a large amount of laccase when grown in medium that contained napthalene.

  • The first zoea of Petrolisthes trilobatus Osawa, 1996, from a female collected in Japan is described and illustrated. Its morphological characteristics are compared with those of other known species of the genus Petrolisthes. The first zoea of P. trilobatus appears very similar to those of P. lamarckii, P. asiaticus and P. hastatus. However, it could be distinguished from the others in having a spine on the lower posterior margin of the carapace, three pairs of setae on the postero-dorsal surface of the telson and minute spinules on the dorsal margins of the abdominal somites 2-5. Based on zoeal morphology, it is suggested that the zoeas of Petrolisthes could be divided into two groups: the first group (P. coccineus, P. moluccensis, P. lamarckii, P. trilobatus, P. asiaticus, P. hastatus, P. pubescens, P. tomentosus, and P. carinipes) and the second one (P. ohshimai, P. armatus, P. boscii, P. tridentatus, P. tonsorius, and P. japonicus).

  • Laccase produced by Pycnoporus cinnabarinus SCH-3 isolated from Korea was partially purified using ultrafiltration, anion exchange chromatography and affinity chromatography, The laccase was produced as the predominant extracellular phenoloxidase during primary metabolism. Neither lignin peroxidase nor manganese-dependent peroxidase were detected in the culture fluid. In order to examine the effect of inducers in laccase production, 2,5-xylidine was added in the culture of Pycnoporus cinnabarinus SCH-3. Addition of 2,5-xylidine enhanced 25-fold laccase production. Purified laccase was a single polypeptide having a molecular mass of approximately 66 kDa, as determined by SDS-polyacrylamide gel electrophoresis, and carbohydrate content of 9%. $K_{m}\;and\;V_{max}$ values for laccase with ABTS [2,2-azinobis (3-ethylbenzthiazoline 6-sulfonic acid)] as a substrate (Lineweaver-Burk plot) was determined to be $44.4{\mu}M\;and\;56.0{\mu}mole$, respectively. The optimal pH for laccase activity was found to be 3.0. The enzyme was very stable for 1 hour at $60{\circ}C$. Half-life ($t_{1/2}$) of the enzyme was about 10 min at $80{\circ}C$. Spectroscopic analysis of purified enzyme indicated that the enzyme was typical of copper-containing protein. Substrate specificity and inhibitor studies for laccase also indicated to be a typical fungal laccase. The N-terminal amino acid sequence of the P. cinnabarinus SCH-3 laccase showed 94% of homology to the N-terminal sequences of laccases from P. cinnabarinus PB and P. coccineus.
