In the current study, an ethyl acetate extract from the endophytic fungus Trichoderma sp. EFI 671, isolated from the stem parts of the medicinal plant Laurus sp. was screened for bioactivity against plant pathogens (Fusarium graminearum, Rhizoctonia solani, Sclerotinia sclerotiorum and Botrytis cinerea), insect pests (Spodoptera littoralis, Myzus persicae, Rhopalosiphum padi) and plant parasites (Meloidogyne javanica). The chemical study of this insect antifeedant extract resulted in the isolation of 1-oleoyl-2-linoleoyl-3-palmitoylglycerol (1), eburicol (2), β-sitostenone (3), ergosterol (4) and ergosterol peroxide (5). The free fatty acids present in compound 1 (oleic, linoleic and palmitic) showed strong dose-dependent aphid antifeedant effects against M. persicae. Liquid (PDB, and SDB) and solid (corn, sorghum, pearl millet and rice) growth media were tested in order to optimize the yield and bioactivity of the fungal extracts. Pearl millet and corn gave the highest extract yields. All the extracts from these solid media had strong effects against M. persicae with sorghum being the most active. Corn increased the content in linolenic, pearl millet the oleic and stearic and sorghum oleic and linolenic acids compared to rice. Their antifeedant effects correlated with linoleic /oleic acids. The phytotoxic effects of these extracts against Lolium perenne and Lactuca sativa varied with culture media, with sorghum being the least toxic.

The present work constitutes the external scientific report of the EFSA open call OC/EFSA/FEED/2015/01. The aim of the call was to provide EFSA with a database from a review on the taxonomical description and potential toxigenic capacities of microorganisms used for the industrial production of feed additives and food enzymes. The review includes microorganisms used as source of feed additives and food enzymes for which EFSA has received or can potentially receive applications for safety assessment, and which have not been recommended for Qualified Presumption of Safety status. The database also comprises the molecular taxonomical identifiers and biosynthetic pathways involved in the production of toxic compounds and the responsible genes. The main result of the project is shown as a database developed according to the EFSA data structure. The methodological aspects and the queries used in the systematic search, as well as the procedure applied for the screening of scientific documents retrieved are described in this report. Details are available in supplementary appendices.In total, 22970 scientific documents were screened in the literature search, from which 411 were initially selected for providing pertinent data for the scope of the project. From the review of the selected articles, 474 bioactive secondary metabolites were recorded and 59 compounds were further studied in order to obtain data on their toxicology and the conditions in which they are produced by the microorganisms used in industrial fermentations. The database generated in this project comprises details that characterise, when available, the production conditions, genes involved and toxicity of these 59 compounds. This provides information that can be used to establish safety measures when using potentially toxigenic microorganisms in industrial fermentations Disclaimer: The present document has been produced and adopted by the bodies identified above as author(s).

“…The marine alga-derived endophytic fungi were the focus of our researches, and a series of new terpenes, steroids, polyketides and alkaloids have been isolated and identified (Miao, Li, et al 2012;Miao, Liang, et al 2012;Ji et al 2013;Liu et al 2013;Sun et al 2013;Miao et al 2014). Trichoderma species were known for the production of functional products (Ahluwalia et al 2015;iqtedar et al 2015). in our continuing chemical investigation towards the marinederived Trichoderma species, Trichoderma citrinoviride cf-27 isolated from the marine brown alga Dictyopteris prolifera has been studied.…”
