One of the riches earth that can be found in sea is brown macroalgae (seaweed). Brown has various pro-perties such as having antibacterial and antifungal properties. type commonly Indonesia Turbinaria conoides. T.conoides been studied for its many benefits, including relieving fever children, insect repellent, fertilizer, also an agent. The components extract were investiga-ted to able inhibit ...

The isolation, structural elucidation and biological activities of oligosporon (1), oligosporol A (2) and oligosporol B (3), three new antibiotics from cultures of the predacious deuteromycete, Arthrobotrys oligospora, are reported. The structures were elucidated by means of high resolution mass and high field N M R spectroscopy. The compounds exhibited weak antimicro­ bial, cytotoxic and hemol...

The coastal water of Aboru village is one site with high diversity marine biological resources such as brown algae. purpose this study was to determine the morphological character algae Turbinaria from Village. procedure consists field collection, and observations in laboratory. characters observed were presence/absence rhizoid/holdfast, cauloid/stipe, phylloid/blades, pyrenoid/vesicle (air bub...

To study the molecular basis for predator-prey coevolution, we investigated how Caenorhabditis elegans responds to the predatory fungus Arthrobotrys oligospora. C. elegans and other nematodes were attracted to volatile compounds produced by A. oligospora. Gas-chromatographic mass-spectral analyses of A. oligospora-derived volatile metabolites identified several odors mimicking food cues attract...

Arthrobotrys thaumasia and musiformis as biocontrol agents against Meloidogyne hapla on tomato plant. Biodiversitas 23: 3659-3666. The use of nematode-trapping fungi a agent is an environmental-friendly step in controlling plants. aim this study was to determine the potential A. reducing at...

The objective of this work was to isolate and identify fungi associated with R. reniformis in cotton roots. Soil samples were collected in cotton fields naturally infested with R. reniformis and from cotton stock plants cultured in the greenhouse. Nematodes extracted from the soil were observed under the stereoscope, and discolored eggs and vermiform stages colonized with mycelia were cultured ...

An N-acetylgalactosamine-specific protein was purified from mycelial homogenates of the nematode-trapping fungus Arthrobotrys oligospora by using affinity chromatography. The molecular weight of the protein was estimated at 22,000 by its comparative mobility on sodium dodecyl sulfate-polyacrylamide slab gels. Pretreatment of nematodes with the purified protein reduced entrapment, indicating a r...

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 ...
