Project description:Aspergillus terreus is an emerging fungal pathogen in immunocompromised patients. Due to intrinsic resistance of AmB against A. terreus and acquiring resistance to azoles, alternative antifungal strategy needs investigation. Thus, we explored the activity of phytochemicals such as Shikonin, gallic acid, coumaric acid and quercetin against A. terreus. Amongst these, shikonin showed significant inhibition at MIC50;2 µg/ml, considered for proteome profiling.

Project description:Aspergillus terreus is a filamentous ascomycota, which is prominent for its production of lovastatin, an antihypercholesterolemic drug. The commercial importance of lovastatin with annual sales of billions of dollars made us to focus on lovastatin biosynthetic cluster proteins. The analysis of these lovastatin biosynthetic cluster proteins with different perspectives such as physicochemical property, structure based analysis and functional studies were done to find out the role and function of every protein involved in the lovastatin biosynthesis pathway. Several computational tools are used to predict the physicochemical properties, secondary structural features, topology, patterns, domains and cellular location. There are 8 unidentified proteins in lovastatin biosynthetic cluster, in which 6 proteins have homologous partners, and annotation transfer is done based on the closely related homologous genes, and their structures are also modeled. The two other proteins that do not have homologous partners are predicted as PQ loop repeat protein that may be involved in glycosylation machinery and as thiolase-acyl activity by the integrated functional analysis approach.

Project description:The filamentous fungus Aspergillus terreus is known to produce both industrially and pharmaceutically important secondary metabolites. The objective of this study is to investigate the effect of exogenously added butyrolactone I (BI) on the submerged culture of A. terreus, especially on the possible regulation of the secondary metabolism on the transcriptional level. In order to elucidate the presumed regulative role of butyrolactone I, a large-scale microarray gene expression study was designed and conducted with an industrially utilised A. terreus strain MUCL38669. A. terreus MUCL38669 was cultured in secondary metabolism inducing submerged conditions for nine days, where butyrolactone I was added at the beginning of the growth phase (at 24 hours p.i.), in the middle of the growth phase (at 96 hours p.i.) or in the late growth phase (at 120 hours p.i.), in addition to the control culture where no exogenous butyrolactone I was added. To obtain comprehensive gene expression profiles over the whole culture time, samples were taken at six time points: 24 hours, 48 hours, 96 hours, 120 hours, 144 hours and 216 hours post inoculation.

Project description:Cultivation of Aspergillus terreus ATCC 20542 in a stirred tank bioreactor was performed to induce the biosynthesis of secondary metabolites and provide the bioprocess-related insights into the metabolic capabilities of the investigated strain. The activation of biosynthetic routes was attempted by the diversification of process conditions and growth media. Several strategies were tested, including the addition of rapeseed oil or inulin, changing the concentration of nitrogen source, reduction of chlorine supply, cultivation under saline conditions, and using various aeration schemes. Fifteen secondary metabolites were identified in the course of the study by using ultra-high performance liquid chromatography coupled with mass spectrometry, namely mevinolinic acid, 4a,5-dihydromevinolinic acid, 3α-hydroxy-3,5-dihydromonacolin L acid, terrein, aspulvinone E, dihydroisoflavipucine, (+)-geodin, (+)-bisdechlorogeodin, (+)-erdin, asterric acid, butyrolactone I, desmethylsulochrin, questin, sulochrin, and demethylasterric acid. The study also presents the collection of mass spectra that can serve as a resource for future experiments. The growth in a salt-rich environment turned out to be strongly inhibitory for secondary metabolism and the formation of dense and compact pellets was observed. Generally, the addition of inulin, reducing the oxygen supply, and increasing the content of nitrogen source did not enhance the production of examined molecules. The most successful strategy involved the addition of rapeseed oil to the chlorine-deficient medium. Under these conditions, the highest levels of butyrolactone I, asterric acid, and mevinolinic acid were achieved and the presence of desmethylsulochrin and (+)-bisdechlorogeodin was detected in the broth. The constant and relatively high aeration rate in the idiophase was shown to be beneficial for terrein and (+)-geodin biosynthesis.
