A gene for the Alternaria major allergen, Alt a 1, was amplified from 52 species of Alternaria and related genera, and sequence information was used for phylogenetic study. Alt a 1 gene sequences evolved 3.8 times faster and contained 3.5 times more parsimony-informative sites than glyceraldehyde-3-phosphate dehydrogenase (gpd) sequences. Analyses of Alt a 1 gene and gpd exon sequences strongly...

1,2-bis-(4-Hydroxy-3-methoxyphenyl)-3-hydroxypropan1-one (evafolin B, 1), 1-(4-hydroxy-3-methoxyphenyl)3-hydroxypropan-1-one (2), were isolated for the first time from the genus Schisandra, along with abscisic acid (3), 4-hydroxybenzaldehyde (4), 4-hydroxybenzoic acid (5), methyl 4-hydroxybenzoate (6), methyl 3,4-dihydroxybenzoate (7), and vanillic acid (8). All the compounds were evaluated for...

In the title hydrate, C(10)H(10)O(4)·H(2)O, the six-membered aliphatic ring that is fused to the benzene ring has a sofa shape, with the hy-droxy group in the 3-position (that represents the sofa back) of the aliphatic ring occupying a quasi-axial position. The hy-droxy group of the aromatic ring is hydrogen-bond donor to the carbonyl O atom; other O-H⋯O hydrogen bonds link the organic mol-ecul...

The role of endophytic fungi isolated from different populations European Ni hyperaccumulators was investigated in regard to the microorganisms' ability enhance hyperaccumulation Noccaea caerulescens. Effects particular species on adaptation N. caerulescens excess were tested by co-cultivation with single strains fungi. Seven these had a positive effect plant biomass production, whereas two inh...

The six major components of M-92, a new antibiotic complex produced by Micromonospora verruculosa MCRL 0404 showed a similar type of antimicrobial spectrum. Among these components, VA-2 exhibited the most potent antimicrobial activity, particularly significantly against some Gram-positive bacteria and Neisseria. VA-2 and BN-1 also exhibited marked inhibitory effects against L-forms of Staphyloc...

A virus infecting the harmful bloon~ causing microalga Heterosjgma akashiwo (Raphidophyceae) was isolated from the coastal water of Nomi Bay, Japan, In July 1996. The isolate caused lysis in 2 strains of H. akashiwo tested and numerous virus-like particles (VLPs) appeared in the lysed algal culture, whereas virus multiplication was not detected in the healthy culture of H. akashiwo without its ...

BACKGROUND AND OBJECTIVES Biodeterioration is an irreversible damage that is caused by colonization of microorganisms on the surface of different materials. Among all microorganisms, fungi play an important role in deterioration of materials. Fungi can colonize on stone surfaces and by secreting different enzymes, organic and inorganic acids and pigments, can cause bio-weathering and changing n...
