“…[27] However, the relationship between floral pollen contributions and the intensity of the antibacterial capacity is not enlightened. [1,7,8] The range of the antibacterial capacity against S. pyogenes is similar to Chilean honeybee pollen samples reported by Velásquez et al, [1] being more effective in the antibacterial grown inhibitions of S. pyogenes than conventional antibiotics; whereas penicillin has shown an inhibition diameter of 5 mm while streptomycin has shown a value up to 24,0 mm. The different behavior of the samples, especially in the antioxidant activity, could be related to the individual polyphenols present in each sample.…”

“…[18] According to Figure 1, the antimicrobial capacity of the HBP3 sample was the highest, which correlates with the carotenoid content. [8] The other HBP samples showed inhibition halo for S. pyogenes ranging between 9.0-13.7 mm without a significant difference, with the lower performance for HBP4, the sample with the lesser contribution of Brassica rapa.…”

Honeybee pollen (HBP) is a mixture of floral pollen collected by honeybees near the hive. It is characterized by a composition rich in phenolic compounds, carotenoids and vitamins that act as free radicals scavengers, conferring antioxidant and antibacterial capacity to the matrix. These bioactive properties are related to the botanical origin of the honeybee pollen. Honeybee pollen samples were collected from different geographical locations in central Chile, and their total carotenoid content, polyphenols profile by HPLC/MS/MS, DPPH radical scavenging capacity, and antimicrobial capacity against S. pyogenes, E. coli, S. aureus, and P. auriginosa strains were evaluated. Our results showed a good carotenoids content and polyphenols composition, while antioxidant capacity presented values between 0 -95 % for the scavenging effect related to the botanical origin of the samples. Inhibition diameter for the different strains presented less variability among the samples, Furthermore, binary mixtures representing the two most abundant species in each HBP were prepared to assess the synergy effect of the floral pollen (FP) present in the samples. Data shows an antagonist effect was observed when assessing the carotenoid content, and a synergy effect often presents for antimicrobial and antioxidant capacity for bee pollen samples. The bioactive capacities of the honeybee pollen and their synergy effect could apply to develop new functional ingredients for the food industry.

“…Os biocorantes são corantes biologicamente sintetizados a partir de microrganismos, geralmente, como metabólitos secundários. Fungos, bactérias e microalgas são bastantes descritos na literatura como produtores de diversificadas moléculas de pigmentos naturais, como: carotenóides, melaninas, flavinas, quinonas, monascinas, violaceína ou índigo (Dufossé, e 2016Del Carmen Chavez-Parga, 2008;Vargas-Sinisterra & Ramírez-Castrillón, 2021). A produção dessas moléculas pode estar relacionada a diferentes fatores, como: defesa aos ataques de outros organismos, defesa a radiações eletromagnéticas danosas, proteção contra agentes oxidantes, proteção contra calor e frio extremos (Liu & Nizet, 2009;Patkar, et al, 2021).…”

Em todo o mundo são produzidos, diariamente, muitos resíduos agroindustriais provenientes de diferentes tipos de processos industriais. Ressaltando aqueles realizados por indústrias de polpas e sucos que descartam a maior parte do peso total das frutas (cascas e sementes). Esses resíduos contêm grandes quantidades de nutrientes, como açúcares, minerais e proteínas, que podem ser biotransformados em moléculas de interesse tecnológico através da aplicação de processos biotecnológicos. Dentre eles, os processos fermentativos com fungos filamentosos vêm como alternativa promissora, pois esses microrganismos são relatados como grandes produtores de metabólitos secundários com aplicação médica e farmacêutica. Como, por exemplo, os biocorantes que são substâncias que proporcionam cor e podem agregar atividade biológica aos produtos, como ação antioxidante e antimicrobiana. O presente trabalho trata-se de uma revisão narrativa sobre o potencial uso de diferentes tipos de resíduos agroindustriais como substratos nutritivos para crescimento fúngico e a produção industrial de seus metabólitos bioativos.

“…Despite the availability of a variety of natural and synthetic antibiotics, the potential of carotenoids as novel antimicrobials has increased recently. Several reports have recorded the antimicrobial potential of carotenoids from seaweed [51] and fungal extracts [52][53][54], as well as from tomatoes [55].…”

Carotenoids from Persimmon (Diospyros kaki Thunb.) Byproducts Exert Photoprotective, Antioxidative and Microbial Anti-Adhesive Effects on HaCaT

et al. 2021

Persimmon (Diospyros kaki Thunb.) fruits are a remarkable source of carotenoids, which have shown protective effects against UV radiation in bacteria, fungi, algae, and plants. The aim of this study was to analyze the photoprotection provided by an acetone extract, rich in carotenoids and obtained from byproducts derived from the persimmon juice industry, against UV-induced cell death in the keratinocyte HaCaT cell line. For this purpose, the cytotoxicity and phototoxicity of carotenoid extract, as well as its intracellular reactive oxygen species (ROS) scavenging and anti-adhesive activities towards HaCaT cells, were evaluated. The in vitro permeation test provided information about the permeability of the carotenoid extract. Persimmon extracts, rich in carotenoids (PEC), were absorbed by HaCaT keratinocyte cells, which reduced the UV-induced intracellular ROS production in treated cells. Thus, PEC exerted a photoprotective and regenerative effect on UV-irradiated HaCaT cells, and this protection was UV dose-dependent. No cytotoxic effect was observed in HaCaT cultures at the concentration tested. PEC treatment also stimulated the adhesion capacity of skin microbiome to HaCaT cells, while exhibiting a significant anti-adhesive activity against all tested pathogens. In conclusion, PEC showed potential for use as a functional ingredient in skin-care products.
