The lichen biota of the Amur Region (southern Russian Far East) was studied in course several geobotanical expeditions. In total 38 species lichens and three lichenicolous fungi are reported for first time Region. Among them four (Fulgidea oligospora, Peltigera frippii, Psora globifera, Rhizoplaca subdiscrepans) new to East nine more — southern East. Four Zeya Reserve Tokinsko-Stanovoy National...

The systematic classification of nematode-trapping fungi is redefined based on phylogenies inferred from sequence analyses of 28S rDNA, 5.8S rDNA and beta-tubulin genes. Molecular data were analyzed with maximum parsimony, maximum likelihood and Bayesian analysis. An emended generic concept of nematode-trapping fungi is provided. Arthrobotrys is characterized by adhesive networks, Dactylellina ...

The systematic classification of nematodetrapping fungi is redefined based on phylogenies inferred from sequence analyses of 28S rDNA, 5.8S rDNA and b-tubulin genes. Molecular data were analyzed with maximum parsimony, maximum likelihood and Bayesian analysis. An emended generic concept of nematode-trapping fungi is provided. Arthrobotrys is characterized by adhesive networks, Dactylellina by a...

Insufficient nutrient and pest infection are two major predicaments for low crop yield in agriculture. Nematodes, a most infectious parasite pest in plants responsible for major yield loss. Chemical phosphate fertilizer made large reserves of it in soil, but part of it is made available to the plants because of irreversible fixation of it with divalent cation. In the present study, Arthrobotrys...

arthrobotrysamerospora (atcc 34468) produced glucoamylase in a semi-synthetic medium containing starch as a sole carbon source. polyacrylamide gel electrophoresis of crude glucoamylase showed three isoenzymes. they were designated as glu i, glu ii and glu iii according to their electrophoretic mobility. these iso-glucoamylases were purified by column chromatography using deae-sephadex a-50. the...
