“…The EA fraction also showed the greatest amount for phenolics and flavonoids content (Table 3). Naturally occurring phenolic and flavonoid compounds are of great interest to the pharmacological industries as well as the food or cosmetic industries, as these compounds exhibit many biological functions including anti-inflammatory, antiallergic, hepatoprotective, antithrombotic, antiviral, anticarcinogenic and vasodilatory actions [34, 35].…”

24Endophytes are microbial colonizers that reside in plants by symbiotic association produces 25 several biological classes of natural products. The current study focuses on the isolation and 26 characterization of bioactive compounds produced by endophytic fungi isolated from the 27 Himalayan yew (Taxus wallichiana) collected from the Mustang district of Nepal. The plant 28 materials were collected from the Lower-Mustang region in the month of October 2016 and the 29 endophytic fungi were isolated on artificial media from inner tissues of bark and needles. 30 Antimicrobial and antioxidant activity, along with total phenolic-and flavonoid-content assays, 31 were used in the evaluation of bioactivity of the fermented crude extracts along with the in vitro 32 ability of the endophytes to produce the anticancer compound Taxol was analyzed. A total of 16 33 fungal morphotypes were obtained from asymptomatic inner tissues of the bark and needles of T. 34 wallichiana. Among the 16 isolates, the ethyl acetate (EA) fraction of isolate MUS1, showed 35 antibacterial and antifungal activity against all test-pathogens used, with significant inhibition 36 against Pseudomonas aeruginosa ATCC 27853 (MIC: 250 µg/ml) and the pathogenic yeast, 37 Candida albicans (MIC: 125 µg/ml). Antioxidant activity was also evaluated using 2,2-diphenyl-38 1-picrylhydrazyl (DPPH). At a concentration of 100 µg/ml, the % radical scavenging activity 39 was 83.15±0.40, 81.62±0.11, and 62.36±0.29, for ascorbic acid, butylated hydroxytoluene (BHT) 40 and the EA fraction of MUS1, respectively. The DPPH-IC50 value for the EA fraction was 81.52 41 µg/ml, compared to BHT (62.87 µg/ml) and ascorbic acid (56.15 µg/ml). The total phenolic and 42 flavonoid content in the EA fraction were 16.90±0.075 µg gallic acid equivalent (GAE) and 43 11.59±0.148 µg rutin equivalent (RE), per mg of dry crude extract, respectively. Isolate MUS1, 44 identified as an Annulohypoxylon sp. by ITS sequencing, also produced Taxol (282.05 µg/L) as 45 shown by TLC and HPLC analysis. Having the ability to produce antimicrobial and antioxidant 46 3 compounds, as well as the anticancer compound Taxol, makes Annulohypoxylon sp. strain 47 MUS1, a promising candidate for further study given that naturally occurring bioactive 48 compounds are of great interest to the pharmacological, food and cosmetic industries.49

“…Each year, about 1.3 billion tons of the food generated globally is wasted. Among these losses, the fruit processing industry generates large amounts of by-products entailing economic and environmental concerns (FAO, 2011;Kowalska et al, 2017). Nonetheless, fruit byproducts are rich in high value-added compounds with antioxidant and antimicrobial properties, and can be valorised through their incorporationdirectly or via extractsin food products.…”

Summary High‐pressure extraction was used to produce pomegranate peel extract, later incorporated in carrot juice. Chemical, microbiological and sensorial analyses were performed during storage to untreated, high‐pressure and thermally processed juices incorporating pomegranate peel extract. Fortified juices showed lower counts for mesophiles and psychrophiles than the nonfortified ones (P < 0.05). Total phenolic and hydrolysable tannin contents, and antioxidant activity had superior values in supplemented juices during storage. The extract did not affect any sensorial parameter. On the 28th day, pressurised juices exhibited lower microbial loads in comparison with heated process, but phenolic compounds, antioxidant activity and several sensorial descriptors were identical between both processing technologies. The β‐ and α‐carotene content decreased after processing, and pressurised juices exhibited higher residual activity for peroxidase (P < 0.05). These data suggest that the application of pomegranate peel extract in treated carrot juices (2.5 mg mL−1) improves their microbial safety and antioxidant capacity, without impairing the sensorial aspects.

“…The high production and disposal of agricultural wastes and their uncontrolled decomposition generate environmental pollution [1]. Worldwide research is in progress to minimize the negative effects of such pollutants in conjunction with the development of potential market demand of value added bio-commodities, such as; fermented beverages, Single-Cell Proteins (SCP), Single-Cell Oils (SCO), bio-colors, flavors, fragrances, polysaccharides, bio-pesticides, plant growth regulators, bioethanol, biogas and bio-hydrogen [2].…”
