“…These pigments are frequently more stable and soluble than pigments from plant or animal sources; in addition, they may present high productivity and are used as additives, color intensifiers, antioxidants, etc. (Méndez et al, 2011). This species was also detected in the present study.…”

Interactions between plants and microorganism are complex and can affect the establishment of plant communities and change ecosystem properties. These interactions are of interest for researchers and have many ecological and biotechnological applications. The present study is the first report on the microbial diversity associated with Butia purpurascens Glassman, and the goal was to isolate and identify the genetic diversity of endophytic and rhizospheric growable microorganisms from B. purpurascens using molecular biology techniques. Endophytic and rhizospheric microorganisms were isolated from the roots and rhizospheric soil of the purple yatay palm. DNA was extracted, and the 16S region for bacteria and internal transcribed spacer (ITS) region for fungi were amplified and sequenced. The resulting sequences were compared with known sequences from GenBank by similarity search using BLASTn. The rhizosphere and roots of B. purpurascens harbor a diverse set of microorganism groups. Fourteen (14) genera of endophytic and 12 genera of rhizospheric bacteria were identified that belonged to three phyla (Proteobacteria, Firmicutes and Actinobacteria), and 11 endophytic and six rhizospheric genera of fungi were identified that belonged to the phylum Ascomycota. The most frequent isolated genera were Enterobacter and Pseudomonas for endophytic bacteria, Gibberella and Codinaeopsis for endophytic fungi, Bacillus and Enterobacter for rhizospheric bacteria, and Ceratocystis for rhizospheric fungi. Differences were observed between the endophytic and rhizospheric microbial communities of B. purpurascens, with some microorganisms only detected in one environment. Further studies with a higher number of individuals are required to confirm these results.

“…Also, pH can affect enzyme activity involved in biosynthesis of pigments (Pisareva et al 2005). Optimum red pigment production by P. purpurogenum GH2 was observed at 24°C and pH 5 in CD medium with no relation between pigment and biomass production (Mendez et al 2011). Afshari et al (2015) reported that Penicillium aculeatum ATCC 1049 produces yellow pigment at 30°C and pH 6.5 while the biomass (11.12 g/L) production was found to be maximum at 30°C and pH 8.…”

Optimisation and characterisation of the orange pigment produced by a cold adapted strain of Penicillium sp. (GBPI_P155) isolated from mountain ecosystem

With globalisation and growing health risks of synthetic colourants, search for pigments from natural sources has increased owing to their non-toxic nature. The present study highlights the bioprospection of natural pigment from a cold adapted fungal strain of Penicillium sp. (GBPI_P155), isolated from soil of Indian Himalayan region. The fungus produced insoluble and orange-coloured pigment in liquid medium with maximum production recorded in potato dextrose (PD) broth at 15°C and 3 pH, while maximum biomass was produced at 25°C and pH 3. While examining the effect of different mineral salts, and carbon and nitrogen sources on pigment production, maximum accumulation of pigment was recorded in PD broth supplemented with 2% maltose. Following production, extraction of pigment was performed using chloroform and characterised partially by UV/vis (λ max at 495 nm and a shoulder peak at 530 nm) and Fourier Transform Infrared (FT-IR) spectroscopy. Thin layer chromatography of chloroform extract resulted in separation of pigment in three fractions with Rf values 0.911, 0.852 and 0.808, which were further analysed using Liquid Chromatography Mass Spectrometry (LC/MS). The overall approach resulted in identification of pigment as a mixture of different derivatives of carotenoids. The extracted pigment also possessed antimicrobial activity against Gram-positive and Gram-negative bacteria and actinobacteria.

“…Some strains of Aspergillus (A. glaucus, A. cristatus and A. repens) 4,5,35,36,[92][93][94] were found to produce known yellow and red HAQN compounds such as emodin (yellow, group A 1 ), physcion (yellow, group A 1 ), questin (yellow to orange-brown, group A 2 ), erythroglaucin (red, group A 1 ), catenarin (red, group C 1 ; see Table 3) and rubrocristin (red, group C 1 ; see Table 3). However, by using Penicillium or Aspergillus strains, …”

Natural pigments and colorants are widely used in the world in many industries such as textile dying, food processing or cosmetic manufacturing. Among the natural products of interest are various compounds belonging to carotenoids, anthocyanins, chlorophylls, melanins, betalains… The review emphasizes pigments with anthraquinoid skeleton and gives an overview on hydroxyanthraquinoids described in Nature, the first one ever published. Trends in consumption, production and regulation of natural food grade colorants are given, in the current global market. The second part focuses on the description of the chemical structures of the main anthraquinoid colouring compounds, their properties and their biosynthetic pathways. Main natural sources of such pigments are summarized, followed by discussion about toxicity and carcinogenicity observed in some cases. As a conclusion, current industrial applications of natural hydroxyanthraquinoids are described with two examples, carminic acid from an insect and Arpink red™ from a filamentous fungus.
