This study reports a new white-rot fungus Cerrena sp. WR1, identified based on an 18S rDNA sequence, which can secrete extracellular forms of laccase with a maximal activity reaching 202 000 U l⁻¹ in a 5-l fermenter. A laccase protein, designated Lcc3, was purified and shown to be N-linked glycosylated by PNGase F and liquid chromatography tandem mass(More)
Two novel hydrogenotrophic methanogens, designated strains P2F9704aT and P2F9705, were isolated from an estuary in Eriln Shi, Taiwan. The cells of strain P2F9704aT were non-motile, irregular cocci 0.9-1.4 microm in diameter. They stained gram-negative. The cells catabolized formate and H2+CO2 to produce methane, but did not utilize acetate, methanol,(More)
Three novel halotolerant, hydrogenotrophic methanogens, designated strains K1F9705bT, K1F9705c and O1F9704a, were isolated from an estuary in Eriln Shi, Taiwan, and from a nearby marine water aquaculture fishpond. These isolates were irregular cocci that stained Gram-negative. Strains K1F9705bT and K1F9705c were non-motile, but strain O1F9704a was weakly(More)
PURPOSE This study was to examine the serum leptin levels in the prediction of pregnancy outcomes in women receiving ovarian hyperstimulation. Effect of leptin on the steroidogenesis was evaluated for granulosa cell (GC) culture in vitro. METHOD Serum levels of leptin and estradiol were measured on Day 2, the time of hCG administration and oocyte(More)
Current next-generation sequencing (NGS) platforms adopt two types of sequencing mechanisms: by synthesis or by ligation. The former is employed by 454 and Solexa systems, while the latter by SOLiD system. Although the pros and cons for each sequencing mechanism have more or less been discussed in a number of occasions, the potential obstacle imposed by(More)
A mesophilic, hydrogenotrophic methanogen, strain CYW4(T), was isolated from deep-sea sediment obtained by the Ocean Researcher I cruiser, ORI-961, in 2011. The sediment was from the deformation front area offshore of south-western Taiwan. Here, seismic reflections indicated that methane hydrates were abundant. The methanogenic substrates utilized by strain(More)
A mesophilic, hydrogenotrophic methanogen, strain S3Fa(T), was isolated from sediments collected by Ocean Researcher I cruise ORI-934 in 2010 near the submarine mud volcano MV4 located at the upper slope of south-west Taiwan. The methanogenic substrates utilized by strain S3Fa(T) were formate and H2/CO2 but not acetate, secondary alcohols, methylamines,(More)
A mesophilic, hydrogenotrophic methanogen, strain ML15(T), was isolated from an aquaculture fish pond near Wang-gong, Taiwan. The cells were irregular cocci, non-motile, 1.5-2.0 microm in diameter and Gram-negative. Cells of strain ML15(T) lysed easily in the presence of SDS (0.1 g l(-1)) and the S-layer protein had an M(r) of 138 800. The catabolic(More)
The aim of this study was to classify certain environmental haloarchaea and methanoarchaea using matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and to expand the archaeal mass spectral database. A total of 69 archaea were collected including type strains and samples isolated locally from different environments.(More)
