Correction to: Lentinus crinitus basidiocarp stipe and pileus: chemical composition, cytotoxicity and antioxidant activity

Basidiocarp structures of Lentinus crinitus: an antimicrobial source against foodborne pathogens and food spoilage microorganisms

“…Stipe had MIC 3.2 times greater than pileus against L. monocytogenes, the pathogenic agent of meningitis and listeriosis, which can lead to death (Koopmans et al 2018); the MFC value was 8.3 times higher against A. ochraceus, a known producer of highly cytotoxicity mycotoxins such as ochratoxins among many others (Bräse et al 2009). Stipe represents about 24% of the total L. crinitus basidiocarp mass and smaller amount of proteins, ashes, organic acids as oxalic and malic acid, and phenolic acids such as p-hydroxybenzoic compared to pileus (Bertéli et al 2021b). The chemical composition, cytotoxicity, and antioxidant activity results for the basidiocarp (pileus and stipe apart) of our study were published in Bertéli et al (2021b) as the samples, the batch, and the assay were the same.…”

“…Phenolics are important antioxidant compounds produced by mushrooms such as p-hydroxybenzoic acid, which has also antimicrobial activity (Manuja et al 2013;Naczk and Shahidi 2006). In L. crinitus basidiocarp, p-hydroxybenzoic was reported at 537 ± 4 µg 100 g − 1 in the pileus and at 791 ± 3 µg 100 g − 1 in the stipe (Bertéli et al 2021b); p-hydroxybenzoic acid from Ganoderma lucidum basidiocarp has MIC from 0.003 to 0.12 mg mL − 1 against A. fumigatus, A. versicolor, A. ochraceus, A. niger, T. viride, P. funiculosum, P. ochrochloron, and P. verrucosum (Heleno et al 2013), which suggests that this phenolic acid is the main compound involved in the antimicrobial activity of L. crinitus basidiocarp stipe.…”

“…L. crinitus basidiocarp stipe extracts could be added to foods and cosmetics as adjuvants for microbial control. L. crinitus basidiocarp stipe and pileus showed reduced cytotoxicity against HepG2 and no cytotoxicity against MCF7, NCI-H460, and HeLa tumor cell lines (Bertéli et al 2021b). Furthermore, the antimicrobial activity of L. crinitus basidiocarp stipe is greater than or equal to the main antimicrobials added in foods and cosmetics, such as sodium sulfite and potassium metabisulfite, which had, for the same microorganisms of our study, MIC values from 1.00 to 3.97 mg mL − 1 and from 0.505 to 2.01 mg mL − 1 , respectively, and MBC values from 0.497 to 4.04 mg mL − 1 and from 0.502 to 2.02 mg mL − 1 , respectively (Bertéli et al 2021a).…”

“…Despite one report on the antimicrobial and cytotoxic activities of L. crinitus entire basidiocarp (Bertéli et al 2021a), there are no antimicrobial data for separated pileus and stipe from this basidiocarp. The stipe represents 24% of L. crinitus basidiocarp mass (Bertéli et al 2021b). It is fibrous, difficult to chew, and generally discarded in the basidiocarp production of L. crinitus; however, it could be a source of antimicrobial compounds.…”
