    Notes: Abstract The reaction of manganese peroxidase (MnP) of the white-rot fungusBjerkandera adusta with synthetic lignin dehydrogenation polymer, DHP) in acetone medium was investigated. Gel-permeation chromatography of the DHP treated by MnP demonstrated depolymerization of syringyl DHP in the reaction mixture containing 70% acetone; moreover, concomitant repolymerization occurred to give highly polymerized products. Guaiacyl DHP was only repolymerized by MnP in the same acetone solution without giving degradation products. Addition of ascorbic acid to reaction mixtures containing acetone resulted in preferential depolymerization of syringyl DHP.

    Topics: Biology
    Notes: Abstract Manganese peroxidase (MnP) and lignin peroxidase (LiP) were produced by growing a white-rot fungusBjerkandera adusta statically, on a wood meal/wheat bran culture in flasks. MnP and LiP reached their maximum activity after 6 and 19 days of inoculation, respectively. Both MnP and LiP are thought to be important enzymes in lignin biodegradation byB. adusta. Ion exchange chromatography showed thatB. adusta produced a single LiP and a single MnP enzyme in wood meal/wheat bran culture. These enzymes were separated and characterized. The molecular weight of MnP was 46,500 with a pl of 3.9. The molecular weight of LiP was estimated to be 47,000 with a pl of 3.5. Spectral analysis demonstrated that both enzymes are heme proteins. Production of these enzymes was also achieved using a rotarysolid culture fermenter. MnP, LiP and veratryl alcohol oxidase were produced byB. adusta in the fermenter.

    Notes: Abstract Sporulation inBipolaris oryzae was induced by UV radiation (295 nm), but the number of conidia gradually decreased with increasing duration of UV radiation longer than 1 min. The inductive effect of UV radiation can be nullified by blue light (459 nm) applied immediately before or after inductive UV radiation shorter than 1 min. In contrast, the number of conidia increased with an increasing duration of blue light applied after inductive UV radiation longer than 1 min, but not if it was applied before UV radiation. The present study firstly revealed the possibility of photoreactivation inB. oryzae sporulation.

    Topics: Biology
    Notes: Abstract The germ tubes ofColletotrichum lagenarium showed negative phototropism to UV-blue (300–520 nm) and far-red (〉700 nm) regions with maximum in the near ultraviolet (NUV) region, while monochromatic radiations of 575–700 nm (yellow-red region) induced positive phototropism with maximum in the red region. Green light (520–575 nm) was ineffective. Negative phototropism-inducing wavelength regions inhibited germ tube growth and positive phototropism-inducing wavelength regions promoted it significantly.Bipolaris oryzae did not show any phototropic response and light did not affect the germ tube growth. These results indicate that the lens effect, in combination with the light growth reaction and light growth inhibition, is the mechanism of the phototropism of germ tubes ofC. lagenarium. NUV radiation, which induced negative phototropism ofC. lagenarium, promoted appressorium formation, while red light, which induced positive phototropism, suppressed it significantly. In the case ofB. oryzae, light did not affect the infection structure formation. These results indicate that negative phototropism of germ tubes ofC. lagenarium favors the infection process by facilitating the contact of the tips of germ tubes with the host surface, while positive phototropism has the opposite effect.

    Notes: Separation of the 1-phenyl-3-methyl-5-pyrazolone (PMP) derivatives of simple disaccharides (maltose, cellobiose, gentiobiose, lactose, and melibiose) by affinity capillary electrophoresis was investigated using lectin-containing neutral phosphate buffers, filled in a linear polyacrylamide-coated capillary. When Lens culinaris agglutinin (LCA) was added, the derivatives of glucobioses were retarded with varying magnitudes depending on the amount of LCA and were well separated from each other and from galactosyl glucose under optimized conditions. Addition of Ricinus communis 60 kDa agglutinin (RCA60) to the phosphate buffer gave a different migration profile, in which the derivatives of galactosyl glucoses were more retarded than those of glucobioses. However, addition of either lectin did not accomplish complete separation of the derivatives of all these disaccharides even under optimum conditions. The addition of two kinds of lectins in appropriate proportions improved separation. Thus, the binary system composed of LCA and RCA60, as well as LCA and soybean agglutinin from Glycine max (SBA), gave better separation of these derivatives, giving peak tops for all derivatives.

    Notes: This review summarizes publications on capillary electrophoresis (CE) of carbohydrates, covering almost all hitherto published papers on this topic. It is designed to be a convenient tool for the literature search by providing a comprehensive table. Since CE analysis of carbohydrates is generally complicated due to the structural diversity of carbohydrate species, an attempt is made in this table to supply detailed information on the analyzed form (underivatized or derivatized, type of derivative) and analytical conditions (capillary size, state of the inner wall, composition of the electrophoretic solution, applied voltage, detection method, etc.), for each combination of carbohydrate species to be analyzed. In addition, a brief overview is presented to help in the literature search.

    Notes: 1-Phenyl-3-methyl-5-pyrazolone (PMP) derivatives of component monosaccharides in glycoproteins (fucose, galactose, mannose, N-acetylgalactosamine and N-acetylglucosamine) and epimeric aldopentoses (arabinose, lyxose, ribose and xylose) were well separated from each other by capillary electrochromatography on a Hypersil ODS column with a mixture of 50 mM N-(2-hydroxyethyl)piperazine-2′-(2-ethanesulfonic acid) buffer, pH 6.0 to ∼ 6.3, and acetonitrile (2.2:1 v/v) as eluent. The elution of these compounds showed relatively strong dependence on the pH and concentration of the buffer salts contained in the eluent, as compared to the elution by pressure-driven high-performance liquid chromatography (HPLC) on the same stationary phase, but separation of PMP-monosaccharides was better than that by HPLC. Retention times of PMP-monosaccharides were highly reproducible with a relative standard deviation (RSD) of ∼ 0.6%, and quantification with an RSD less than 5% could be achieved using 3-O-methylglucose as an internal standard.
