“…In their study, the authors used the bioaugmentation of Trichoderma harzianum SQR-T037. Ellagic acid is a product of the degradation of ellagitannins with the enzymes known as ellagitannases, which are synthesized by Aspergillus fungi [ 51 ]. This research may indicate that these fungi use EA as a source of energy.…”

Currently, natural polymer materials with bactericidal properties are extremely popular. Unfortunately, although the biopolymer material itself is biodegradable, its enrichment with bactericidal compounds may affect the efficiency of biodegradation by natural soil microflora. Therefore, the primary objective of this study was to evaluate the utility of fungi belonging to the genus Trichoderma in facilitating the degradation of chitosan film modified with cinnamic acid and ellagic acid in the soil environment. Only two strains (T.07 and T.14) used chitosan films as a source of carbon and nitrogen. However, their respiratory activity decreased with the addition of tested phenolic acids, especially cinnamic acid. Addition of Trichoderma isolates to the soil increased oxygen consumption during the biodegradation process compared with native microorganisms, especially after application of the T.07 and T.14 consortium. Isolates T.07 and T.14 showed high lipolytic (55.78 U/h and 62.21 U/h) and chitinase (43.03 U/h and 41.27 U/h) activities. Chitinase activity after incorporation of the materials into the soil was higher for samples enriched with T.07, T.14 and the consortium. The isolates were classified as Trichoderma sp. and Trichoderma koningii. Considering the outcomes derived from our findings, it is our contention that the application of Trichoderma isolates holds promise for expediting the degradation process of chitosan materials containing bactericidal compounds.

“…Among them, the three most abundant compounds obtained were geraniin, corilagin and EA, which belong to the ellagitannin family. On the other hand, De León-Medina et al (2023) [14] extracted the ellagitannins of rambutan peel via microwave/ultrasound, which were isolated via Amberlite XAD-16 column chromatography and implemented in an SSF as a substrate. Via HPLC/MS, it was observed that through SSF, geraniin allowed biodegradation in EA and ellagitanase was the enzyme involved in the biodegradation process with a value of 25.49 U/L in a period of 6-12 h.…”

“…It has an ovoid shape that measures approximately 5 to 8 cm long and 2 to 5 cm wide with a weight of 22.4 and 64.7 g; it is associated with other subtropical fruits such as lychee and longan (Jahurul et al, 2020;Peixoto Araujo et al, 2021) [11,12]. Rambutan is composed of seed, pulp and peel; at the moment of being industrially processed for consumption for the production of sold canned products, juices, liquors, jams or jellies, the seeds and peel are discarded as agro-industrial by-products [13,14]. In Mexico, rambutan is mainly cultivated in the state of Chiapas in the region of Soconusco, but it can also be harvested in other states of Mexico such as Veracruz, Tabasco, Guerrero, Michoacán and Nayarit, where the climate favors the growth of the tree [15].…”

Rambutan (Nephelium lappaceum L.) is a tropical fruit that is originally from Southeast Asia and it was introduced to Mexico in the 1960s; the fruit’s peel is known to possess ellagitannins such as ellagic acid which give the peel great biological activity; solid-state fermentation has been used to obtain said compounds and rambutan peel can be used as a fermentation support/substrate; this work aims to obtain, identify and quantify ellagic acid obtained via SSF with a strain of yeast. The water-absorption index and the support’s maximum moisture were determined. To determine the ideal conditions for ellagic acid accumulation, a Box–Behnken 3k experimental design was applied using variables such as temperature, moisture and inoculum. The maximum accumulation time of ellagic acid via solid-state fermentation was determined to be 48 h with ideal conditions of 30 °C, 60% moisture and 1.5 × 107 cells/g using S. cerevisiae, and high-performance liquid chromatography was used to identify ellagic acid, geraniin and corilagin as the most abundant compounds. The maximum recovery of ellagic acid was 458 ± 44.6 mg/g. HPLC/ESI/MS analysis at 48 h fermentation showed biodegradation of geraniin and corilagin due to ellagic acid. Mexican rambutan peel has been demonstrated to be a suitable substrate for SSF.

“…The content of hydrolyzable and condensed tannins was measured using the Folin-Ciocalteu reagent, in accordance with De León-Medina et al, 2023 [40], with some modifications. For hydrolyzable tannins, 20 µL of the sample was mixed in a microplate with 20 µL of Folin-Ciocalteu reagent (St. Louis, MO, USA, Sigma-Aldrich) and incubated for 5 min.…”

Prickly pear peel (Opuntia ficus-indica) residues can be used as a substrate in solid-state fermentation to obtain bioactive compounds. The kinetic growth of some Aspergillus strains was evaluated. A Box–Hunter and Hunter design to evaluate the independent factors was used. These factors were temperature (°C), inoculum (spores/g), humidity (%), pH, NaNO3 (g/L), MgSO4 (g/L), KCl (g/L), and KH2PO4 (g/L). The response factors were the amount of hydrolyzable and condensed tannins. The antioxidant and antimicrobial activity of fermentation extracts was evaluated. Aspergillus niger strains GH1 and HT3 were the best for accumulating tannins. The humidity, inoculum, and temperature affect the release of hydrolyzable and condensed tannins. Treatment 13 (low values for temperature, inoculum, NaNO3, MgSO4; and high values for humidity, pH, KCl, KH2PO4) resulted in 32.9 mg/g of condensed tannins being obtained; while treatment 16 (high values for all the factors evaluated) resulted in 3.5 mg/g of hydrolyzable tannins being obtained. In addition, the fermented extracts showed higher antioxidant activity compared to the unfermented extracts. Treatments 13 and 16 showed low inhibition of E. coli, Alternaria sp., and Botrytis spp. The solid-state fermentation process involving prickly pear peel residues favors the accumulation of condensed and hydrolyzable tannins, with antioxidant and antifungal activity.
