Secondary metabolites in the Parastagonospora nodorum-wheat pathosystem
… effectors. Such is the case for the P. nodorum secondary metabolites (SMs). Bioinformatic analysis of the P. nodorum genome has revealed that it contains around 40 genes responsible for biosynthesising the core structure of different SMs which provides this fungus the capacity to produce a vast …

Secondary Metabolites from Xylaria Endophytes: The isolation and structure elucidation of secondary metabolites from Xylaria endophytes by chemical and spectroscopic methods
… the isolation and structure elucidation of secondary metabolites from a number of endophytic Xylaria fungi. Six Xylaria endophytes were surface cultured on an aqueous malt extract-glucose medium. The fungus A311R, from a palm tree in Thailand, produced nonane-1,2,3-tricarboxylic acid, which …

A Phytochemical Analysis of Secondary Metabolites in Eupatorium Serotinum
… and unique properties of natural compounds. All metabolites are produced from the metabolic cycle, which is a pathway that provides energy for the organism. These metabolic compounds vary greatly and are classified based on their function within the organism. Primary metabolites are abundant and …

Nematicidal, antimicrobial and acaricidal activity of plant secondary metabolites
… azedarach and Armoracia rusticana and their secondary metabolites such as α, β- and α, β, γ, δ- unsaturated aldehydes, isothiocyanates and polyphenols as potential nematicidal against the root knot nematode Meloidogyne spp. We deal also about the possible mode of action of aromatic aldehydes …

Studies on secondary metabolites produced by actinomycetes and cyanobacteria
Biosynthetic studies compounds showed that the Adda unit of nodularin was derived from C-2, C-3 and the phenyl ring of scL-phenylalanine as well as acetate and methionine. A separate feeding experiment with (2-$\sp{13}$C) pyruvate suggested that the methylaspartate (MeAsp) unit could be derived …

The roles of secondary metabolites in microcystis inter-strain interactions
… on the genomic as well as on morphological and secondary metabolite levels. Microcystis communities are composed of a variety of diversified strains. The focus of this study lies on potential interactions between Microcystis representatives and the roles of secondary metabolites in these …

Biosynthetic characterisation of secondary metabolites from stromatolite cyanobacteria Symploca sp. 1013
Cyanobacteria are known to produce secondary metabolites that exhibit a wide range of chemical activities. Many of these compounds are toxins, however, an increasing amount of metabolites with potential therapeutic bioactivities are also being discovered. The majority of these metabolites are …

An analysis of microbial film fermentor system for production of secondary metabolites
… system, which is used for the production of a secondary metabolite, is analyzed through computer simulation techniques. Penicillin fermentation was chosen for the model system. From the steady-state analysis, it was found that a complete-mixed contacting pattern is superior to a plug flow …

Inhibition of Alzheimer’s type toxic aggregates of tau with fungal secondary metabolites
… medicinally important compounds. We identified secondary metabolites obtained from Aspergillus nidulans as tau aggregation inhibitors. We identified a novel class of tau aggregation inhibitors, azaphilones. Four of the azaphilones inhibited tau aggregation and disassembled pre-formed tau …

Indole diterpenoid secondary metabolites produced by the Epichloë festucae var. lolii – Lolium perenne symbiosis.
The indole diterpenoid intermediates of lolitrems in a crude extract of Lolium perenne (L. perenne) seed infected with Epichloë festucae var. lolii (E. festucae var. lolii) and their biological activity against porina larvae were investigated. Liquid-liquid partitioning of the crude extract, …
