abstract

microorganisms are important components of soil. some soil filamentous fungi such aspenicilium produce many bioactive small molecules, or secondary metabolites, that range frombeneficial bioactive compounds to harmful toxins. in this study, the metabolites of threepenicillium species (p. goditanum, p. moldavicum and p. corylophilum) were extracted byadding ethyl acetate to liquid cultures. the metabolites were determined using gaschromatography and mass spectrometry. the results obtained from the gc-ms analysis showedthat penicillium species are sources of bioactive compounds. we have identified differentgroups of compounds, such as alkaloids, alkenes, sesquiterpens, fatty acids, and essential oils.among them, 1,3,8-p-menthatriene, 2-methylenecyclohexane, anthracene, neoisolongifolene,[14] annulene and thioxanthene in p. goditanum, isocyclocitral, coumarin-6-ol and 2, 4, 6-trimethoxystyrene in p. moldavicum as well as asarone in p. corylophilum were majorcompounds. moreover, several compounds, such as oxalic acid, dibenzothiophene,hexadecanoic acid, and alkane hydrocarbons, were identified in all species.

Identification of some secondary metabolites produced by four Penicillium species

Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...

Penicillium menonorum, a new species related to P. pimiteouiense

Penicillium menonorum is described as a new monoverticillate, non-vesiculate species that resembles P. restrictum and P. pimiteouiense. On the basis of phylogenetic analysis of DNA sequences from four loci, P. menonorum occurs in a clade with P. pimiteouiense, P. vinaceum, P. guttulosum, P. rubidurum, and P. parvum. Genealogical concordance analysis was applied to P. pimiteouiense and P. parvum...

Biological control of Penicillium italicum, P. digitatum and P. expansum by the predacious yeast Saccharomycopsis schoenii on oranges

In this study we evaluated the ability of Saccharomycopsis schoenii Nadson and Krassiln (UWO-PS 80-91) as biocontrol agent against plant pathogenic filamentous fungi P. expansum Link (UFMG 01-2002), P. italicum Wehmer (LCP 61.1199), and P. digitatum (Pers.: Fr.) (LCP 984263, LCP 68175 and LCP 4354). S. schoenii was able to reduce disease severity in oranges inoculated with all fungi. Among the ...
