Basauxia and Ashtaangam of Hyphorrycetes from Southeast Asia.
Subramanian, C.V. ;
The Korean Journal of Mycology, volume 20, issue 4, 1992, Pages 281~284
Two interesting new hyphomycetes collected on rachis of an unidentified palm (Palmao) from Malayasia are described and their taxonomy is discussed in this paper. One of them is unique in producing basauxic conidiophores from conidiophore mother cells that are sessile, simple, cylindrical or cupulate, and solitary, gangliar, acrogenous, dry phragmoconidia. It is classified in a new genus Basauxia, as a new species, B. pulchra. The other hyphomycete is also unique in producing characteristic solitary, eight-celled, eight-armed gangliar conidia on simple conidiophores. A new genus, Ashtaangam is proposed for it in which it is placed as a new species, A. sundaram.

Zohri, A. A. ; Sabah, Asber M. ; Abdel-Gawad, K. M. ;
The Korean Journal of Mycology, volume 20, issue 4, 1992, Pages 302~308
Seven genera and 15 species of fungi were isolated from 50 samples of then different steps of dried onion (5 samples of each step) collected from an onion factory in Sohag Governorate, Egypt, and grown on glucose-Czapek's agar (7 genera and 15 species) and 10% NaCl glucose-Czapek's (2 genera and 6 species). The average total counts of fungi were gradually decreased throughout the different steps of drying from 2090 to zero and 152 to zero colonies/g on glucose-Czapek's agar and 10% NaCl glucose-Czapek's agar media, respectively. Aspergillus was the most common genus on the two types of media used. The dominant species were Aspergillus niger, A. flavus, A. terreus, Penicillium chrysogenum and Fusarium of oxysporum on glucose-Czapek's agar and A. terreus and A. niger on 10% NaCl glucose-Czapek's agar. The chloroform extracts of different samples were tested for the presence of mycotoxins using thin layer chromatographic analysis. The results indicated that aflatoxin was present at concentrations decreased throughout the different steps of the drying from step No. 1, onion bulbs,
; to step No. 8, standard A,
while step Nos. 9 & 10 (completely dry powdered onion) were free from aflatoxin. Citrinin was also present in the first three steps at concentrations gradually decreased from 30 to 10 mg/kg.
Change in Size Measurements of Powdery Mildew Conidia in Relation to Air Temperature
Shin, Hyeon-Dong ;
The Korean Journal of Mycology, volume 20, issue 4, 1992, Pages 309~314
Nine species of powdery mildew fungi were examined to understand the change in size of conidia in relation to air temperature. Of these, Sphaerotheca aphanis, S. fusca and S. pannosa showed constant value of conidial sizes regardless of changes in air temperature. The length/width ratio in the conidia of Erysiphe, artemisiae and E. sordida increased as the air temperature rose. E. cichoracearum gave the result against that shown in the above two species of Erysiphe. The conidia of Microsphaera pseudolonicerae became decreased in their width as the air temperature fell. The length/width ratio of conidia was markedly increased. M. alphitoides and M. robiniae showed variable size measurements in conidia regardless of changes in air temperature and studies for it needed for additional examination in future.
Examination of Parameters Affecting Polymerase Chain Reaction in Studying RAPD
Yoon, Cheol-Sik ;
The Korean Journal of Mycology, volume 20, issue 4, 1992, Pages 315~323
The effects of several parameters on PCR amplification in using RAPD were studied. The results of this study suggest that approximately 15 ng of genomic DNA in
of reaction mixture results in discrete and reproducible PCR products. In addition, the results indicate that concentration or amounts of reaction components studied are highly inter-dependent in their effects, and RNA can interfere severely with PCR amplification. Suitable concentrations or amounts of reaction components were found to be 30 ng of 10-mer primer,
of dNTP, 0.001% gelatin 1.5 mM
, 10 mM Tris-Cl (pH 8.8), 50 mM KCl, 0.1% Triton X-100, 2 units of Taq DNA polymerase, and 15 ng of RNase-treated genomic DNA in
of reaction mixture.

On the five interspecific protoplast fusants of Ganoderma lucidum and G. applanatum was the antitumor test performed. The fusant F-2 was selected, to examine the cultured mycelia (protein bound polysaccharide) as antitumor components. When a dose of 20 mg/kg/day of each components purifed from F-2 fusant was, i.p., injected into ICR mice, the inhibition ratio of Fr. II against the solid form of sarcoma 180 increased to 1.5 times as compared with that of their parents. When Fr. II was examined for immunopotentiation activity, it increased the amount of the superoxide anion in activated macrophages to 1.2 times and the count of hemolytic plaque forming cells in the spleen to 4.3 times as compared with that of each control group. Its chemical analysis showed 85.2% polysaccharide which consisted of glucose, galactose, mannose, fucose and xylose, and 0.39% protein of 15 amino acids. The content of hexosamine was 0.39% and the molecular weight of Fr. V was

Trichoderma spp. are an effective control agent for damping-off or other plant diseases. The interaction between. T. hamatum and Rhizoctonia solani on the rhizosphere or surface soil were examined to assess the possible roles of antibiosis or competition in the mechanisms of biological control agents as a basic research. In a proportional comparison, total bacteria, fungi, actinomycetes and Trichoderma spp were 65%, 8.8%, 25.9% and 0.28% respectively in their distribution in the soil. Among Trichoderma spp isolated, the 5 species of Trichoderma spp were indentified as T. koninggii, T. pseudokoninggii, T. aureoviridi, T. hamatum and T. viride respectively. In a mycoparasitic test, one isolate of T. hamatum strain Tr-5 showed an enzymatic ability to break fungal hyphae into piecies and infected on the R. solani hyphae showing a parasitism. Spore germination of the all isolates of Trichoderma spp showed a 1.7-7.3% of germination in natural soil conditions, but the percentage was high in sterile soil indicating all the natural soil were fungistatic on conidia of Trichoderma spp. In rhizosphere competent assay in pea plant, the antagonistic T. hamatum, T. viride, T. koninggii, T. pseudokoninggii showed a colonizing upper soil depth in rhizosphere around 1-3 cm in root zone, but the colonizing ability was much reduced along the deeper the soil depth. Propagule density was decreased in deeper the soil layer. Disease development rate treated alone with plant pathogens, Fusarium solani, Rhizoctonia solani, Cylindrocarpon destructans increased, but disease incidence rate reduced in treatment with combinations with antagonistic T. hamatum strain Tr-5.

The effect of the addition of various vegetable oils on the mycelial growth was studied. Most vegetable oils were proved to be stimulative for the mycelial growth, and the best mycelial growth (12 mg/ml) was obtained with the addition of cotton seed oil. Several agricultural wastes i.e., rice straw, peanut hull, sawdust, rice hull, cocoa hull, coffee waste and beer waste were empolyed as substrates for sporophore production of p. sajor-caju. The biological efficiency(BE) for sporophore productions of rice straw and peanut hull were 36.4% and 32.6%, respectively. The highest yield of sporophore was obtained from the mixture of rice straw (50%) and beer waste (50%)(BE 109.6%) followed by peanut hull (50%) and beer waste (50%)(BE; 74.5%).
