This study aimed to evaluate the growth performance, pigment content changes, essential amino acids (EAAs), fatty acids (FAs), and proximate composition of Azolla pinnata and Azolla caroliniana grown in a greenhouse. Plants were grown in nitrogen-free Hoagland?s solution at 28?2?C/21?2?C, day/night temperature and 60-70% humidity and examined on the 3rd, 5th, 10th and 15th days. The mean percentage of plant growth and relative growth rate for A. pinnata were 119% and 0.148 gg-1day-1, respectively, while for A. caroliniana these values were 94% and 0.120 gg-1day-1, respectively. Compared to day 3, the amount of total chlorophyll obtained on day 15 decreased significantly (p<0.05) for A. pinnata while the total phenolic and flavonoid contents increased significantly (p<0.05) from the 3rd to the 15th day. However, the total phenolic and flavonoid contents did not differ (p>0.0.5) in A. caroliniana. The crude protein, lipid, cellulose, ash values and the amounts of EAAs were higher in A. pinnata than A. caroliniana. Palmitic acid, oleic acid, and lignoceric acid were found to be predominant in A. pinnata and A. caroliniana. From the plant growth and pigment contents, we concluded that A. pinnata grew faster than A. caroliniana and its photosynthetic efficiency was more effective.

Abstract Soy whey, a liquid nutritional by-product of soybean manufacture, is rich in proteins, oligosaccharides and isoflavones. Soy whey can be used to produce functional beverages, instead of discarding it as a waste. In this study, unfermented soy whey (USW) and Cordyceps militaris SN-18-fermented soy whey (FSW) were investigated and compared for their physicochemical and functional properties by high performance liquid chromatography (HPLC) and DNA damage assay. Results show that C. militaris SN-18 fermentation could increase the contents of essential amino acids, total phenolic and flavonoid and isoflavone aglycones and eliminate the oligosaccharides in soy whey. Furthermore, C. militaris SN-18 could significantly enhance the ABTS radical scavenging ability, reducing power and ferric reducing power of soy whey, and its fermented products could prominently attenuate Fenton reaction-induced DNA damage. These findings indicate that soy whey can potentially be converted into a novel soy functional beverage by C. militaris SN-18 fermentation. Graphical abstract

In recent years, a substantial amount of evidence has pointed to the key role of free radicals and other oxidants as the main culprits for aging and degenerative diseases associated with aging, such as cancer, cardiovascular diseases, cataract, decline of the immune system and brain dysfunctions. The objective of this work was therefore to detect variations in total phenol and flavonoid content, and in antioxidant activity of samples of V. montevidensis. Dried samples were submitted to extraction to obtain the hexane, ethyl acetate and ethanol fractions. Phytochemical prospecting and an analysis of the phenolic content and antioxidant activity was carried out. The data was analyzed according to the mean±standard deviation and submitted to analysis of variance followed by Tukey's test with a significance of (p < 0.05). Flavonoids, tannins, coumarins, terpenoids, steroids, alkaloids and anthraquinones were detected in the samples. The content of total flavonoids varied between 3.18±0,58 and 7.22±0,17 g/100g, while the total phenols ranged from 1.13±0.16 to 18.44±0.21 g/100g. The extracts produced EC50 between 339.75±6.56 and 278.33±23.11 μg/mL.

Abstract Cowpea is considered as one of the underutilized legumes which is rich in secondary metabolites. These metabolites can be detected during the plant growth and the contents increase especially after the plants are stressed both abiotic and biotic. This study aimed to determine total phenolic and flavonoid contents as well as antioxidant activity in seeds of eight cowpea genotypes. Two extraction solvents (70% acetone and 70% acidified acetone) were used to extract the secondary metabolites in those cowpea genotypes. Total flavonoid contents of those genotypes extracted in 70% acetone and 70% acidified acetone were in the range from 7.28 to 10.90 mg CE/g and 7.84 to 11.58 mg CE/g, whereas total phenolic contents were from 15.20 to 19.99 mg GAE/g and 15.03 to 21.15 mg GAE/g. Inhibition percentages of antioxidant activity were in the range from 46.90 % to 59.46 % and 50.71 % to 63.81 % for 70% acetone and 70% acidified acetone, respectively. Both solvents were effective to extract those secondary metabolites. Flavonoid and phenolic contents of MLGU 0239 were the highest among other genotypes, which were 11.58 mg CE/g and 21.15 GAE/g and antioxidant activity was 63.81 % inhibition after being extracted with 70% acidified acetone. This study observed the variation of the secondary metabolites among eight cowpea genotypes with different seed coat colours.

Juvenile of Trichogaster lalius was reared under three photoperiod conditions (0L:24D, 12L:12D, 16L:08D) for 60 days to examine the growth performance under laboratory conditions. The maximum growth was observed in the juvenile of T. lalius exposed to 16:00 hrs. light. The mean body weight of different groups of juvenile fish exposed to different light conditions were significantly different (p<0.05) from each other which was observed from 20thday of the experiment. The absolute, specific, and relative growth rates were found to be maximum in the group exposed to 16:00 hrs. light duration. The present study indicated that 16:00 hrs. light duration was considered to be better for the growth of juvenile of T. lalius under controlled condition.

AbstractThis study aimed to determine the standard amount of antioxidant content and compounds of the propolis for the standardization of propolis. For this purpose, the total flavonoids, total phenolic, CUPRAC antioxidant capacity content and the diversity of phenolic and flavonoid components of these propolis samples were found by HPLC determined at the 23 propolis samples which were collected different regions of Turkey. Beside that, the similarities and differences of these 23 provinces to each other according to their antioxidant capacities were investigated by multidimensional scaling analysis. The total flavonoid content in the propolis samples were determined between 21.28 and 152.56 mg CE/g. The total phenolic content in the propolis samples was found between 34.53 mg and 259.4 mg GAE/g. CUPRAC antioxidant capacity of the propolis samples and antioxidant range was found from 95.35 to 710.43 mg TE/g. Also, 4 flavonoid [Quercetin (min.1.12–max.4.14 mg/g), Galangin (min.0.72–max.40.79 mg/g), Apigenin (min.1.07–max.17.35 mg/g), Pinocembrin (min.1.32–max.39.92 mg/g] and 6 phenolic acid [Caffeic acid (min.1.20–max.7.6 mg/g), p-Coumaric acid (min.1.26–max.4.47 mg/g), trans-Ferulic acid (min.1.28–max.4.92 mg/g), Protocatechuic acid (1.78 mg/g), trans-Cinnamic acid (min.1.05–max.3.83 mg/g), Caffeic Acid Phenethyl Ester (CAPE) (min.1.41–max.30.15 mg/g)] components were detected as mg/g, in different ratios in propolis samples collected from different regions. The feature of this study, so far, is to have the maximum number of samples representing the Turkish propolis, and so is thought to help to national and international propolis standard workings.

Presently, the bioprocessing of agricultural residues to various bioactive compounds is of great concern, with the potential to be used as plant growth promoters and as a reductive of various diseases. Lycopersiconesculentum, one of the most consumed crops in the human diet, is attacked by Fusarium wilt disease, so the main aim is to biocontrol the pathogen. Several fungal species were isolated from decayed maize stover (MS). Trichodermaasperellum was chosen based on its organic acid productivity and was molecularly identified (GenBank accession number is MW195019). Citric acid (CA) was the major detected organic acid by HPLC. In vitro, CA of T.asperellum at 75% completely repressed the growth of Fusariumoxysporum f. sp. lycopersici (FOL). In vivo, soaking tomato seeds in CA enhanced the seed germination and vigor index. T. asperellum and/or its CA suppressed the wilt disease caused by FOL compared to control. There was a proportional increment of plant growth and yield, as well as improvements in the biochemical parameters (chlorophyll pigments, total phenolic contents and peroxidase, and polyphenol oxidase activities), suggesting targeting both the bioconversion of MS into CA and biological control of FOL.
