Detection of basal stem rot (BSR) by Ganoderma of oil palms was based on foliar symptoms and production of basidiomata. Enzyme-Linked Immunosorbent Assays-Polyclonal Antibody (ELISA-PAB) and PCR have been proposed as early detection methods for the disease. These techniques are complex, time consuming and have accuracy limitations. An ergosterol method was developed which correlated well with t...

Coccidioidomycosis is a systemic mycosis caused by the dimorphic fungi Coccidioides spp. The treatment for chronic and/or disseminated coccidioidomycosis can be prolonged and complicated. Therefore, the search for new drugs is necessary. Farnesol is a precursor in the sterol biosynthesis pathway that has been shown to present antifungal activity. Thus, the objective of this study was to evaluat...

Fungi form the biggest microbial biomass and are key drivers of hydrocarbon biodegradation. We here describe standard cultivation methods for fungi that use hydrocarbons either as sole carbon and energy source or co-metabolically degrade them. The methods include both liquid (Protocols 1 and 2) and solid-state cultivation approaches (Protocol 3) as well as a versatile protocol to monitor fungal...

BACKGROUND The increasing availability of 'omics' databases provide important platforms for yeast engineering strategies since they offer a lot of information on the physiology of the cells under diverse growth conditions, including environmental stresses. Notably, only a few of these approaches have considered a performance under recombinant protein production conditions. Recently, we have ide...

Fungal sphingolipids contain ceramide with a very-long-chain fatty acid (C26). To investigate the physiological significance of the C26-substitution on this lipid, we performed a screen for mutants that are synthetically lethal with ELO3. Elo3p is a component of the ER-associated fatty acid elongase and is required for the final elongation cycle to produce C26 from C22/C24 fatty acids. elo3delt...

In this study, we examined the importance of membrane ergosterol and sphingolipids in the drug susceptibilities of Candida albicans. We used three independent methods to test the drug susceptibilities of erg mutant cells, which were defective in ergosterol biosynthesis. While spot and filter disk assays revealed that erg2 and erg16 mutant cells of C. albicans became hypersensitive to almost all...

Recently there has been a dramatic rise in the number of immunocompromised patients within our population, resulting from infection with HIV or from aggressive medical practices. These patients are especially susceptible to infections by opportunistic fungi leading to mycoses1). In the course of our antifungal screening program, we have devised an efficient screening method for selective toxici...
