2. Fundamental bioflotation aspects of hematite using an extracted Rhodococcus opacus by-product
Abstract The aim of this study is to assess the floatability of hematite using a crude biosurfactant (BS) extracted from Rhodococcus opacus. Throughout high-pressure ethanol extraction, unrefined surfactant was extracted from the bacteria with a yield of 0.3 g/L. An FTIR analysis on this extract, shows the presence of alcohol (–OH) and ketone (C=O) groups,

3. Comparative assessment of antioxidant activity and biochemical composition of four seaweeds, Rocky Bay of Abu Qir in Alexandria, Egypt
Abstract The current study estimated the antioxidant activity and biochemical composition of four seaweeds; Toania atomaria (Phaeophyta), Padina pavonia (Phaeophyta), Jania rubens (Rhodophyta) and Corallina elongate (Rhodophyta). The highest total antioxidant activity was observed with ethanol extract of T. atomaria (44.6 ± 1.6 mg ascorbic acid equivalents/

4. Food production potential of Favolus brasiliensis (Basidiomycota: Polyporaceae), an indigenous food
Abstract The Amazon region has shown commercial potential for native mushroom species, such as mushrooms produced by the Yanomami people, who already sell more than 10 Amazon species. Among the species collected and consumed by the Yanomami people is Favolus brasiliensis (Fr.) Fr. (Basidiomycota: Polyporaceae), which occurs naturally in tropical areas of Cen

5. A new polysaccharide isolated from Dendrobium offcinale, stimulates aquaporin-3 expression in human keratinocytes
Abstract Polysaccharides are the major components of the water extract from Dendrobium officinale, which have been thoroughly studied and found to have favorable moisturizing properties on mammalian skin. However, the structures of polysaccharides on skin moisturizing properties remains unknown. The aim of this study was to extract and characterize D. offici

6. ANTIPROMASTIGOTE AND CYTOTOXIC ACTIVITIES OF FLAVONOIDS FROM Fridericia speciosa LEAVES
Fridericia speciosa (Bignoniaceae) is a liana that occurs in humid to dry vegetation in eastern and southeastern Brazil. Species belonging to the genus Fridericia are employed as medicinal plants. This study evaluates the antipromastigote and cytotoxic activities of the crude extract, fractions, and compounds isolated from F. speciosa, and an HPLC (High-Perf

8. Bromatological aspects of Lentinus crinitus mushroom (Basidiomycota: Polyporaceae) in agroforestry in the Cerrado
Abstract Much of the diversity of mushrooms is still unknown to science. In the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. In particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their

9. Características do trato digestivo, metabolizabilidade e retenção de nutrientes em frangos de corte alimentados com complexo enzimático
ABSTRACT The objective was to evaluate the digestive tract characteristics, metabolizability and nutrient retention of broilers fed diets supplemented with enzyme complex (EC). To evaluate the characteristics of the digestive tract 600 female Cobb 500 birds were used, distributed in a completely randomized design, with 5 inclusion levels of the EC (0; 100, 2

10. Isolation, in vitro and in silico Evaluation of Phenylethanoid Glycoside from Arrabidaea brachypoda as Lipoxygenase Inhibitor
Lipoxygenase (LOX) plays an important role in inflammatory processes and Arrabidaea brachypoda (DC.) Bureau (Bignoniaceae) has been described as presenting anti-inflammatory activity. Therefore, the objective of this study was to develop a high-performance liquid chromatography (HPLC) procedure to directly recognize LOX inhibitor compounds in A. brachypoda c

11. Structural and Functional Stabilization of Sericin from Bombyx mori Cocoons in a Biopolysaccharide Film: Bioorigami for Skin Regeneration
Development and optimization of a bioorigami film with silk sericin was pursued for skin regeneration. Several formulations were produced, with varying integrated sericin contents, viz. 0, 1, 2, 5, 10, 20 and 50 mgsericin mLfilm-1. The physico-chemical characteristics of the bioorigami films produced were evaluated via infrared spectrophotometry, X-ray diffr

12. Aromatic Polyketides and Macrolides from Microsphaeropsis arundinis
The endophytic fungus Microsphaeropsis arundinis was isolated from the capitula of the tropical plant Paepalanthus planifolius (Eriocaulaceae). The fungus was cultivated in seven different media, and the ethyl acetate extracts were tested against tumor cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. The culture wa
