Culture studies on the mycobiont isolated from Parmotrema reticulatum (Taylor) Choisy: Metabolite production under different conditions
(Springer Heidelberg, 2009-11)
A strain of the lichen mycobiont isolated from a thallus of Parmotrema reticulatum was cultured axenically on different media. The morphology, anatomy, growth of the colonies, and metabolite production were studied. The ...
A STRATEGY FOR THE RAPID IDENTIFICATION OF FUNGAL METABOLITES AND THE DISCOVERY OF THE ANTIVIRAL ACTIVITY OF PYRENOCINE A AND HARZIANOPYRIDONE
(Soc Brasileira Quimica, 2016-07-01)
The isolation and identification of bioactive metabolites from complex extracts obtained from microbial growth media is a time consuming, costly, and labor-intensive task. A strategy to rapidly identify secondary metabolites ...
A green, simplified, and efficient experimental setup for a high-throughput screening of agri-food by-products – From polar to nonpolar metabolites in sugarcane solid residues
(2020-12-20)
From an environmental perspective, searching for useful compounds in agri-food by-products by employing inefficient and polluting analytical procedures is paradoxical. This work aimed to develop a green, simplified, and ...
Terrestrial and marine Antarctic fungi extracts active against Xanthomonas citri subsp. citri
(2018-07-01)
This study aims to obtain secondary metabolites extracts from filamentous fungi isolated from soil and marine sediments from Antarctica and assess its potential antibacterial activity on Xanthomonas citri subsp. citri, the ...
Use of Experimental Design for the Optimization of the Production of New Secondary Metabolites by Two Penicillium Species
(AMER CHEMICAL SOC, 2010)
A fractional factorial design approach has been used to enhance secondary metabolite production by two Penicillium strains. The method was initially used to improve the production of bioactive extracts as a whole and ...
Improvement of bioactive metabolite production in microbial cultures—A systems approach by OSMAC and deconvolution-based 1HNMR quantification
(2019-08-01)
Traditionally, the screening of metabolites in microbial matrices is performed by monocultures. Nonetheless, the absence of biotic and abiotic interactions generally observed in nature still limit the chemical diversity ...
STEROIDAL METABOLITES IN CHILEAN RIVER SEDIMENTS INFLUENCED BY PULP MILL EFFLUENTS
(Soc Chilena QuimicaConcepcionChile, 2013)
Integration of Plasma Membrane and Nuclear Signaling in Elicitor Regulation of Plant Secondary Metabolism
(Natural Products, 2008-08-01)
The plant kingdom represents a valuable source of natural products of commercial interest. These compounds, named secondary metabolites, are not essential for the survival of plants, but confer them some advantages that ...
Bioprospecção de microrganismos endofíticos isolados de Tabebuia spp. e Hymenaea courbaril e identificação da produção de metabólitos de interesse biotecnológico
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2014-11-28)
Microorganisms, such as those belonging to the groups of Penicillium, Bacillus, Paenibacillus, represent represent an important source for the production of bioactive metabolites with varied applications. The production ...
NMR-based metabolite profiling of Selaginella convoluta in different hydration states and the unprecedented occurrence of anabasine in lycophytes
(2021-06-01)
Selaginella convoluta is a Brazilian endemic, desiccation tolerant plant with an effective drought-resistance mechanism. Herein, nuclear magnetic resonance (NMR)-based metabolite profiling was used to investigate this ...
