“…Advances in production of biologically active metabolites have opened up new possibilities for more extensive industrial scale-up applications (Vannelli et al 2007). Physiologically active compounds such as antibiotics, antitumor drugs, antibodies, hypocholesterolemic drugs, anticancer drugs, immunosuppressants, plant hormones, growth promoters for livestock, alkaloids, statins (Vieira et al 2008;Demain 2014;Khan et al 2014), phenolic compounds, terpenes, steroids (Hasnat et al 2015), and antioxidants (Borderes et al 2011) are obtained by fungal culture in bioprocess. Fungi are also recognized by their wide potential in enzyme production of commercial scale (Demain 2014;Hansen et al 2015), biotransformation process (Aguirre-Pranzoni et al 2011), and synthesis of organic acids (Liaud et al 2014).…”

Natural coumarins and derivatives are compounds that occur naturally in several organisms (plant, bacteria, and fungi) consisting of fused benzene and α-pyrone rings. These compounds show high technological potential applications in agrochemical, food, pharmaceuticals, and cosmetics industries. Therefore, the need for bulk production of coumarins and the advancement of the chemical and pharmaceutical industries led to the development of synthetic coumarin. However, biotransformation process, synthetic bioengineering, metabolic engineering, and bioinformatics have proven effective in the production of natural products. Today, these biological systems are recognized as green chemistry innovation and business strategy. This review article aims to report the potential of fungi for synthesis of coumarin. These microorganisms are described as a source of natural products capable of synthesizing many bioactive metabolites. The features, classification, properties, and industrial applications of natural coumarins as well as new molecules obtained by basidiomycetes and ascomycetes fungi are reported in order to explore a topic not yet discussed in the scientific literature.

“…In another study, antioxidant activity in Pycnoporus sanguineus broth was evaluated via the DPPH method. The highest antioxidant activity (around 80% of radical inhibition) was registered during the stationary phase, with a similar potential as the synthetic antioxidant BHT, after 30 days of cultivation (Borderes et al 2011).…”

Crude extract samples of Pleurotus pulmonarius and Pycnoporus cinnabarinus were taken during growth in liquid broth in an airlift reactor. Growth was monitored indirectly by sugar consumption and pH profile. During growth Pleurotus pulmonarius consumed glucose more slowly than Pycnoporus cinnabarinus, reaching a final pH of 8.0. In contrast, Pycnoporus cinnabarinus started consuming glucose faster from the beginning to the end with a pH of 3.6, suggesting the production of different metabolites while they grow in the same culture broth. Additionally, antioxidant activity, polyphenol and flavonoid contents, as well as laccase and hydrolase activities were quantified in the culture extracts during the fermentation. Pleurotus pulmonarius showed higher antioxidant activity than Pycnoporus cinnabarinus. Both fungi have a very low polyphenol and flavonoid content. Values of amylase and pectinase activities were similar in crude extracts of both fungi; however, cellulase, xylanase, invertase, and laccase activities showed higher levels in crude extract of Pleurotus pulmonarius. Antimicrobial and insecticidal activities were also evaluated in each crude extract. In fact, Pycnoporus cinnabarinus presented a very strong bacteriostatic and bactericidal effect against Escherichia coli and Staphylococcus aureus and reliably killed Diatraea magnifactella larvae, while Pleurotus pulmonarius did not showed any negative effect on the growth of these bacteria or larvae.

“…Embora, inferior aos controles catequina e BHT a atividade antioxidante promovida por P. ostreatoroseus é considerável, pois para extratos de cogumelos os valores de descoloração da solução por sequestro do radical DPPH são considerados bons nos intervalos entre 30-80% (ALAM et al (2010). Resultados semelhantes foram obtidos pelo cultivo entre 10 a 25 dias do micélio de Pycnoporus sanguineus (BORDERES, 2011), superior a ao basidioma de P. enrygii e inferior ao micélio de P. enrygii e Agaricus blazei (54,6%; 68,15), (ZIEBA et al;QUEIROZ et al, 2016). Para demonstrar a eficiência na atividade antioxidante dos extratos de P. ostreatoroseus, os resultados da porcentagem de sequestro do radical DPPH foram expressos como EC50 (mg/mL), (Figura 1).…”

Pleurotus ostreatoroseus é um cogumelo brasileiro cultivado e consumido em algumas regiões do país. No entanto, pouco se conhece a respeito de sua composição e efeitos biológicos. Com o intuito de promover a popularização desta espécie nativa e a segurança alimentar para o consumo este estudo teve como objetivo analisar os compostos bioativos e os efeitos antioxidante e antiproliferativo do extrato hidroalcóolico de Pleurotus ostreatoroseus Singer. Foram estimadas as concentrações em compostos fenólicos, ácido ascórbico e carotenoides. Os efeitos biológicos foram analisados por meio método de descoloração do radical DPPH e teste do Allium cepa. Foi observado que P. ostreatoroseus apresenta concentração em compostos bioativos superior a outros cogumelos do gênero e como consequência apresenta boa atividade antioxidante. Com relação aos efeitos sobre o ciclo celular de A. cepa foi verificado efeito antiproliferativo por redução do índice mitótico e ausência de genotoxicidade. Assim, P. ostreatoroseus pode ser indicado para consumo com segurança quanto à mutagenicidade e a pode beneficiar a saúde pela qualidade em compostos bioativos e efeitos biológicos potenciais.
