“…Furthermore, it was found that A. parasiticus growth and spore germination was greater in the presence of Mcapsules and Mcapsules/FA, compared with those in buffer acetate control. This effect can be attributed to the presence of lecithin in the capsules, since it is reported that lecithin accelerates the growth of fungus, such as in Anthracophyllum discolor, which uses it as a carbon source (Bustamante, Rubilar, & Diez, 2014). The addition of FA in Nparticles and Mparticles potentiated its inhibitory effect, compared with the matrices without FA.…”

(2017) Preparation of chitosan matrices with ferulic acid: physicochemical characterization and relationship on the growth of Aspergillusparasiticus, CyTA -Journal of Food, 15:1, 65-74, DOI: 10.1080/19476337.2016 To link to this article: https://doi.org/10. 1080/19476337.2016 Antioxidant, anticarcinogenic, and antimicrobial properties have been reported for ferulic acid (FA), therefore, its application interests both food and agriculture research. FA was immobilized in different chitosan (CS) matrices, physicochemicaly characterized and the effect on Aspergillus parasiticus ecological parameters evaluated. Nanoparticles (Nparticles), microparticles (Mparticles) and microcapsules (Mcapsules) of 35-40 nm, 30-40 μm, and 20 μm, respectively were obtained; FA incorporation in matrices affected their morphology, physicochemical properties, and their fungistatic effect. The effect of the particles was dependent on the matrix exposed. Nparticles and Mparticles showed high FA immobilization efficiency as well as a good fungistatic effect against A. parasiticus: Radial growth at 168 h was 28.46 ± 1.01 and 28.84 ± 1.36 and the inhibition of spore germination at 30 h was 57.44 ± 0.22 and 55.74 ± 2.19, for Nparticles and Mparticles, respectively compared with control cultures. Abnormalities in mycelium, hyphae, and spores morphology were observed, as well as low sporulation due particle interaction with the fungus.Preparación de matrices de quitosano con ácido ferúlico: Caracterización físicoquímica y su relación en el crecimiento de Aspergillus parasiticus RESUMEN El ácido ferúlico (AF) presenta propiedades antioxidantes, anticancerígenas y antimicrobianas, siendo de interés para su aplicación en alimentos y agrícultura. El AF fue inmovilizado en diferentes matrices de quitosano, se caracterizó fisicoquímicamente y se evaluó su efecto sobre Aspergillus parasiticus. Se obtuvierón nanopartículas, micropartículas y microcápsulas de 35-40 nm, 30-40 µm y 20 µm, respectivamente. La incorporación de AF en matrices afecto su morfología, propiedades fisicoquímicas y su efecto fungistático, dependiendo de la matriz expuesta. Las nano y micropartículas mostraron gran eficiencia de inmovilización de AF y efecto fungistático sobre el hongo: inhibición de crecimiento radial a 168 h de 28,46±1,01 y 28,84±1,36 y de germinación de esporas en 30 h de 57,44±0,22 y 55,74±2,19, respectivamente. Asimismo se observaron anomalidades en micelio y morfología de hifas y esporas, así como baja esporulación, debido a la interacción entre las partículas con el hongo. Las microcápsulas no ejercieron efecto antifúngico, sin embargo, tanto las nano-como las micro-partículas son buenos candidatos para el control de hongos.

“…The aggressive wood rot fungi which are widely spread in the world, thanks to their enzymes it could be an excellent candidate for direct biodegradation of pollutants. Most of the current research focused mostly on the activities of these ligninolytic enzymes to understand the enzymatic mechanism of PCP degradation in wood rot fungi, and lignolytic enzymes LiP, MnP and Lac were found to play important role in organic pollutant degradation [7][8][9][10][11]. Usually, when fungi increase their enzymatic activity, they showed a higher degradation of PCP.…”

“…Extracellular ligninolytic enzymes and cytochrome P450 enzymes of wood rot fungi have been reported to be responsible for organic pollutants degradation. Phanerochaete chrysosporium [4], Phanerochaete sordida [5], Trametes hirsuta [6], Trametes versicolor [7], Lentinula edodes [8], Bjerkandera adusta [9], Anthracophyllum discolor [10], Laetiporus cincinnatus, Fomes fomentarius, Ganoderma applantum and Pleurotus ostreatus [11] are some of the wood rot fungi that show the ability to degrade PCP, and methylation and dechlorination are common reactions in transformation of PCP by these fungi. Among them, P. chrysosporium and T. versicolor have been the most widely used wood rot fungi for PCP degradation.…”

Pentachlorophenol (PCP) has been introduced into the environment mainly as a wood preservative and biocide. The degradation and transformation of PCP in liquid culture by wood-decaying fungus capable of degrading organochlorine pesticides was investigated in this study. The results of tolerance test showed that the tolerance level of Phlebia acanthocystis to PCP in potato dextrose agar medium was higher than that of other Phlebia species. At the end of 10 days of incubation, P. acanthocystis was able to remove 100% and 76% of PCP (25 μM) in low-nitrogen and potato dextrose broth media, respectively. The decrease of PCP in P. acanthocystis culture is accompanied by the formation of pentachloroanisole and p-tetrachlorohydroquinone via methylation and oxidation reactions. Moreover, the p-tetrachlorohydroquinone formed is rapidly converted to methylated products including tetrachloro-4-methoxyphenol and tetrachloro-1,4-dimethoxybenzene. The activities of lignin peroxidase and manganese peroxidase were found to increase in extracellular fluid from fungal culture treated with high-concentration PCP, with maximum values of 169.6 U/L and 73.4 U/L, respectively. The in vitro degradation of PCP and p-tetrachlorohydroquinone was confirmed using extracellular fluid of P. acanthocystis, suggested that the methylation of both compounds is related to extracellular enzymes. Degradation of PCP was efficiently inhibited by piperonyl butoxide or 1-aminobenzotriazole, demonstrating that cytochrome P450 monooxygenase is involved in fungal transformation of PCP, particularly in the oxidation of PCP to p-tetrachlorohydroquinone. Additionally, P. acanthocystis mineralized 9.3% of the PCP to 14 CO 2 in low-nitrogen culture during 42 days. Results obtained in the present study are in favor of the use of P. acanthocystis as a microbial tool of remediation of PCP-contaminated sites.
