Novel antimicroalgal substances halymecins A (1), B (2) and C (3) were isolated from the fermentation broth of a Fusarium sp. and halymecins D (4) and E (5) from an Acremonium sp. The structures of these halymecins, Fig. 1, were determined based on extensive 2D NMR studies as well as mass spectral data. These chemical structures are conjugates of di- and trihydroxydecanoic acid. Halymecin A sho...
Cephalosporium acremonium ATCC 48272 cells were immobilized on various adsorbents and in various entrapment matrices. The influence of the incubation period, the best immobilization technique and the optimum concentrations of the selected matrices were investigated. From the results of the repeated batch fermentation in shake flasks, a good level of antibiotic was maintained for a period of abo...
The biosynthesis of pyrrocidines, fungal PK-NRP compounds featuring a strained [9]paracyclophane, was investigated in Acremonium zeae. We used a synthetic L-tyrosine probe, labelled with oxygen 18 as a reporter of phenol reactivity and carbon 13 as a tracer of incorporation of this exogenous precursor. The ((18)O)phenolic oxygen was incorporated, suggesting that phenol behaves as a nucleophile ...
In an ongoing survey of Korean indigenous fungi, three fungal strains belonging to the Sordariomycetes were isolated from soil samples. These strains were designated KNU16-001, KNU16-002, and KNU16-009, and identified as Ambrosiella grosmanniae, Acremonium sclerotigenum, and Trichocladium asperum, respectively, based on morphological characterization and phylogenetic analysis using internal tra...
For tall fescue in the southeastern USA, long term persistence, competitiveness, yield, and summer survival are directly related to the presence of a fungal endophyte (Neotyphodium coenophialum; formerly called Acremonium coenophialum) living in the fescue plant. However, cattle grazing forage from the predominant USA tall fescue cultivars infected with their naturally occurring endophyte strai...
