Abstract
Sunscreen and sunblock are crucial skincare products to prevent photoaging and photocarcinogenesis through the addition of chemical filters to absorb or block ultraviolet (UV) radiation. However, several sunscreen and sunblock ingredients, mostly UV filters, have been associated with human and environmental safety concerns. Therefore, the exploration and discovery of promising novel sources of efficient and safer compounds with photoprotection-related activities are currently required. Marine invertebrates, particularly their associated microbiota, are promising providers of specialized metabolites with valuable biotechnological applications. Nevertheless, despite Actinobacteria members being a well-known source of bioactive metabolites, their photoprotective potential has been poorly explored so far. Hence, a set of methanolic extracts obtained from Cliona varians-derived actinomycetes was screened regarding their antioxidant and UV-absorbing capacities (i.e., photoprotection-related activities). The active extract-producing strains were identified and classified within genera Streptomyces, Micrococcus, Gordonia, and Promicromonospora. This is the first report of the isolation of these microorganisms from C. varians (an ecologically important Caribbean coral reef-boring sponge). The in vitro cytotoxicity on dermal fibroblasts of oxybenzone and the selected active extracts revealed that oxybenzone exerted a cytotoxic effect, whereas no cytotoxic effect of test extracts was observed. Accordingly, the most active (SPFi > 5, radical scavenging > 50%) and nontoxic (cell viability > 75%) extracts were obtained from Streptomyces strains. Finally, LC-MS-based characterization suggested a broad chemical space within the test strains and agreed with the reported streptomycetes' chemodiversity. The respective metabolite profiling exposed a strain-specific metabolite occurrence, leading to the recognition of potential hits. These findings suggest that marine Streptomyces produce photoprotectants ought to be further explored in skincare applications.

The applicability of high-speed counter-current chromatography for preparative separation of biosynthesis products: Glycosylation products as example. J Sep Sci 2021; 44:4368-4375. [PMID: 34687498 DOI: 10.1002/jssc.202100544] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 09/22/2021] [Accepted: 10/15/2021] [Indexed: 11/08/2022]
Abstract
Biosynthesis is a promising way to manufacture desired products, however, the purification of its final products is a tough work due to the huge amount of reaction matrix. Liquid stationary phase of high-speed counter-current chromatography could easily avoid the commonly disadvantages that occurred in traditional column chromatography in the field of biosynthesized products purification. This characteristic makes high-speed counter-current chromatography particularly applicable for final products separation in biosynthesis. In this study, the glycosylation products of Silybin B by one-pot glycosylation were successfully purified by high-speed counter-current chromatography to show the applicability of high-speed counter-current chromatography for preparative separation of biosynthesis products. An optimized n-hexane/ethyl acetate/methanol/water (2:5:2:3, v/v/v/v) system was applied in this study. As a result, four Silybin B glycosylation products, including 7 mg of Silybin B-5-O-β-D-glucoside (SG-1), 12 mg of Silybin B-3-O-β-D-glucoside (SG-2), 10 mg of Silybin B-7-O-β-D-glucoside (SG-3), and 24 mg of Silybin B-20-O-β-D-glucoside (SG-4), were simultaneously separated from 200 mg of glycosylation crude products, with the purity of 89.3, 95.2, 96.4, and 97.5%, respectively. Their structures were identified by spectroscopic analysis.

Abstract
The marine environment represents one of the most underexplored environments in the world. Marine sponges have a higher taxonomic diversity according to definite environmental conditions. They have been considered interesting sources for bioactive compounds. Dictyoceratida sponges are divided into five families which are widely distributed and habituating different types of micro-organisms. However, some secondary metabolites are probably not produced by the sponges themselves, but rather by their associated micro-organisms. These secondary metabolites are characterized by different chemical structures and consequently different biological activities. This review outlines the reported secondary metabolites from micro-organisms associated with Dictyoceratida sponges and their investigated biological activities from 1991 to 2019. The increasing research studies in this field can play a major role in marine microbial natural products drug discovery in the future.

Abstract
Phelligridin LA (PLA) is a natural product with vigorous free radical scavenging activities accumulated in the liquid fermentation of herbal medicinal fungus Inonotus baumii. Aiming to establish an efficient isolation method of PLA from the fermentation broth, we evaluated the adsorption of PLA by macroporous resins. The best resin ADS-17 was screened for six candidates with various physical properties and adsorption behaviors. Studies on the thermodynamics and kinetics of the process revealed that the adsorption reaction could take place spontaneously, which implied that the heat generated in adsorption might compensate for the decrease in entropy. The Freundlich theory could be utilized to fit the experimental data. The pseudo-second-order equation could describe the process, and the adsorption rate was primarily controlled by liquid film diffusion and pore diffusion. The influencing operation factors (temperature, pH, and the ratio of fermentation broth to resin) of the adsorption process were optimized with response surface methodology. The optimized condition (temperature 22.81 °C, pH 5.19, and the ratio of fermentation broth to resin or RLS 5.11) supported an adsorption rate of 97.03%. These findings would be indispensable for further optimization of the efficient separation of PLA from the fermentation broth, and the fermentation production of PLA in which separation would be included.

Front Microbiol 2019; 10:915.

Abstract
Co-culture of different microbes simulating the natural state of microbial community may produce potentially new compounds because of nutrition or space competition. To mine its metabolic potential in depth, co-culture of Streptomyces rochei MB037 with a gorgonian-derived fungus Rhinocladiella similis 35 was carried out to stimulate the production of new metabolites in this study, using pure cultivation as control. Five metabolites were isolated successfully from co-culture broth, including two new fatty acids with rare nitrile group, borrelidins J and K (1 and 2), one chromone derivative as a new natural product, 7-methoxy-2,3-dimethylchromone-4-one (3), together with two known 18-membered macrolides, borrelidin (4) and borrelidin F (5). The structures of 1–3 were elucidated by using a combination of NMR and MS spectroscopy, ester hydrolysis, and optical rotation methods. Interestingly, 1 and 2 were obtained only in co-culture. Though 3 was gained from either co-culture or single culture, its production was increased significantly by co-culture. Compound 1 exhibited significant antibacterial activity against methicillin-resistant Staphylococcus aureus with a MIC value of 0.195 μg/mL.
