Fatty acid profiles of oomycetes (Halophytophthora and Phytopythium spp.) from Philippines mangroves.

Mangroves create an ecological environment for a diverse assemblage of organisms, including marine and mangrove oomycetes. Halophytophthora spp., in particular, are isolated from fallen senescent mangrove leaves.

sp. nov., an extremely halophilic archaeon isolated from a saturated brine pond of a saltern.

A novel extremely halophilic archaeon, strain RHB-C, was isolated from a saturated brine pond of a solar saltern in Bolinao, Pangasinan, Philippines. Colonies were orange-red-pigmented, smooth, convex and round on a solid modified growth medium containing 25 % (w/v) of total salts. Cells of strain RHB-C on the solid modified growth medium were ovoid-shaped (0.

Marine Oomycetes (Halophytophthora and Salispina): A Potential Source of Fatty Acids with Cytotoxic Activity Against Breast Adenocarcinoma Cells (MCF7).

Marine oomycetes are ubiquitous, fungus-like eukaryotes known to produce fatty acids with potential anticancer activity. The long chain omega-3 and omega-6 fatty acids are currently popular and considered as safe when used as nutraceuticals in cancer treatment. In this study, crude fatty acids from three marine oomycetes, Halophytophthora spp.

A revision of , its placement in a new family, (), and description of a fourth species, sp. nov.

The genus was recently described for saprotrophic estuarine oomycetes with aculeolate or spiny sporangia. The genus currently contains three species, , , and , the latter two previously included in . During a survey of mangrove-inhabiting oomycetes in the Philippines, an isolate of (USTCMS 1611), was obtained from a decaying mangrove leaf.

Degradation of Polycyclic Aromatic Hydrocarbons by Moderately Halophilic Bacteria from Luzon Salt Beds.

Background: Polycyclic aromatic hydrocarbons (PAHs) are common environmental contaminants which are highly toxic due to their carcinogenic and mutagenic effects. They are released into the environment by incomplete combustion of solid and liquid fuels, accidental spillage of oils and seepage from industrial activities. One of the promising processes mitigating PAHs is through biodegradation.

TLC Screening Profile of Secondary Metabolites and Biological Activities of Salisapilia tartarea S1YP1 Isolated from Philippine Mangroves.

The Salisapilia species are estuarine oomycetes of the mangrove and saltmarsh ecosystem. To date, reports on the secondary metabolites and biological activities of these microorganisms are wanting. In this study, secondary metabolites in broth ethyl acetate extracts (BEAE) and mycelial ethyl acetate extracts (MEAE) of Salisapilia tartarea S1YP1 isolated from yellow senescent mangrove leaves were screened by Thin Layer Chromatography (TLC).

Decolorization of Selected Synthetic Textile Dyes by Yeasts from Leaves and Fruit Peels.

Background: Discharge of textile dyes into the environment poses a significant threat. They are poorly biodegradable and toxic due to their complex composition and aromatic structures. In the search for alternatives to physical and chemical treatments, biodegradation of synthetic dyes by various microbes is emerging as an effective and promising approach.
