“…The biological significance of polyketide pigments involves resistance to a variety of adverse environmental factors (desiccation, exposure to extreme temperatures, irradiations), to antimicrobial activity. Many observations have also been published with regard to the antioxidant activity of pigments’ protective action against lethal photo oxidation, inhibition of mutagenesis, enhancement of the immune response, and inhibition of tumour development [19,20,21,22,23,24,25].…”

Marine-derived fungi that inhabit severe changing environments have gained increasing interest for their ability to produce structurally unique natural products. Fungi belonging to the Talaromyces and the close Penicillium genera are among the most promising microbes for bioactive compound production, including colored metabolites. Coupling pigment producing capability with bioactive effectiveness would be a valuable challenge in some specific fields such as dyeing, cosmeceutical, or food industries. In this sense, Talaromyces albobiverticillius 30548, a red pigment producing strain, has been isolated from the marine environment of Reunion Island, Indian Ocean. In this research, we analyzed the effect of temperatures (21–27 °C) and salinity levels (0–9%) on fungal growth and pigment production. Maximum pigment yield was obtained in non-salted media, when cultured at 27 °C after 10 days of submerged fermentation in PDB. However, maximum dry biomass production was achieved at stressed condition with 9% sea salts concentrated media at the same temperature. The results indicate that salinity of the culture media positively influences the growth of the biomass. Inversely, pigment production decreases with increase in salinity over 6%. Color coordinates of secreted pigments were expressed in CIELAB color system. The hue angles (h°) ranged from red to yellow colors. This indicated that the color distribution of fungal pigments depends on the salinity in the culture media. This study emphasizes the impact of abiotic stress (salt and temperature) on the growth and metabolome of marine-derived fungal strains.

“…The analysis of the chemical composition of the essential oils of these plants reveals a number of chemical compounds both monoterpenes and sesquiterpenes, mainly related to their health benefits [5]. The ability to understand the relationship between the chemical composition and the activity always poses a challenge, particularly for the well-known and widely used medicinal plants and spices [6][7][8][9]. The interpretation and discussion of the relationships between the activity and composition on the basis of tabular and/or graphical data presentation are often extremely subjective.…”

The application of chemometric approaches in the comparison of the activity and the chemical composition of essential oils of 10 aromatic Lamiaceae species (Melissa officinalis, Mentha piperita, Mentha aquatica, Mentha longifolia, Ocimum basilicum, Origanum vulgare, Rosmarinus officinalis, Salvia officinalis, Salvia nemorosa, and Thymus vulgaris) is reported in this paper. The standard methodology of principal component analysis needs too many principal components (PCs) to effectively describe the relationships between studied samples. PC1 explains only 47.58% of the total variance reflecting the most significant differences between essential oils of S. nemorosa and Or. vulgare. PC2 explains 19.77% of the total variance and shows the most significant differences between the essential oils of M. aquatica compared with those of S. nemorosa, S. officinalis and Or. vulgare. Efficient compression of the data was possible by hierarchical clustering analysis (HCA) complemented with a color map. HCA shows that essential oils of both investigated representatives of genus Salvia are characterized by a high content of oxygenated sesquiterpenes and remarkable antifungal activities, but low antibacterial and antioxidant activity, particularly for the S. officinalis. Unlike sage, the essential oils of oregano and thyme have high content of aromatic oxygenated monoterpenes and low antifungal but pronounced antibacterial activity. Peppermint, basil, rosemary, and lemon balm are characterized by high content of oxygenated monoterpenes and aliphatic components as well as by high antioxidant 2,2-diphenyl-1-picrylhydrazil activity of essential oils.
