Enzymatic preparation of biotinylated naturally-occurring sialylglycan and its molecular recognition on a quartz-crystal microbalance.
A biotinylated sialylglycan was prepared enzymatically by endo-M, and binding behavior of an SSA lectin was studied on a different coverage of a sialylglycan-immobilized 27 MHz quartz-crystal microbalance (QCM).
Evidence of self-inhibition by filamentous fungi accounts for unidirectional hyphal growth in colonies.
Hyphal growth in filamentous fungi proceeds in an unidirectional radial pattern from a point inoculation. An inhibitor produced, secreted, and absorbed by the advancing hyphae has been speculated to account for directional growth. Working with Mucor and Aspergillus, laboratory evidence is provided f...
Bovine mycotic abortion in Denmark.
A survey is given of the occurrence of mycotic infections associated with abortion in Danish cattle. During a period of six years a total of 748 samples of placenta material were examined. Mycotic abortion was demonstrated in 101 cases (14%). The case rate was significantly higher (21%) during the w...
Microbial transformation of hypoestenone.
Preparative-scale fermentation of hypoestenone (1) with Mucor ramannianus (ATCC 9628) has resulted in the isolation of 8(9)alpha-epoxyhypoestenone (2) and the new metabolites 8(9)alpha-epoxy-12,13-anhydrohypoestenone (3), 17-hydroxyhypoestenone (4), 13alpha,18-dihydroxyhypoestenone (5), and 13beta,1...
Mode of action of chitin deacetylase from Mucor rouxii on N-acetylchitooligosaccharides.
The mode of action of chitin deacetylase from the fungus Mucor rouxii on N-acetylchitooligosaccharides with a degree of polymerization 1-7 has been elucidated. Identification of the sequence of chitin oligomers following enzymatic deacetylation was verified by the alternative use of two specific exo...
Mucor pyelonephritis. Report of a case diagnosed by urine cytology, with diagnostic considerations in the workup of funguria.
We report a unique case in the cytologic literature in which urine cytology provided insight into the diagnosis, renal mucormycosis. CASE: The patient, a diabetic and IV drug abuser, presented with complaints of left flank pain, fever and dysuria. All urine cultures were negative. A computed tomogra...
[The role of imperfect fungi in etiopathogenesis of allergic rhinitis].
In this paper the role of imperfect fungi in etiopathogenesis of perennial rhinitis was examined. In a group of 26 patients the concentration of total IgE and IgE specific of Candida albicans, Aspergillus fumigatus, Alternaria alternata, Mucor racemosus and Cladosporum herbarum was signified. Overse...
Fungi associated with herbal drug plants during storage.
Samples of sundried herbal drug plant parts stored for sale were purchased from four herbal markets located in Ibadan, Nigeria. The plant parts were analysed for mycoflora associated with their storage. Fungal colony counts ranged from 0.60 x 10(2) to 3.50 x 10(2) within the period of the survey. Tw...
Transformation of a methionine auxotrophic mutant of Mucor circinelloides by direct cloning of the corresponding wild type gene.
A transformation system has been developed for Mucor circinelloides, by direct cloning of a wild-type methionine gene that complements the auxotrophic mutation. The marker gene isolated was associated with an autonomous replication sequence (ARS) functional in this zygomycete. Southern hybridisation...
[Sporangiospore lipids of the mycelial fungus Mucor ramannianus incapable of dimorphic growth].
We investigated the lipid composition of M. ramannianus sporangiospores, which retained the capability of initiating mycelial growth in the course of long-term cultivation of the spore-forming mycelium. It was demonstrated that sporangiospores contained high concentrations of triacylglycerides (TAG)...
