  The use of mango peel (agricultural waste with no appreciable value to industries or competitive use as food) as alternative and cost-effective biomass for the production of bioethanol was examined. Thus, the aim of this study was to select performed yeasts strains able to ferment sugars containing in peel mango. The methods used, included: enzymatic hydrolysis with Bacillus and simultaneous saccharification and fermentation with W6 and B1, yeasts isolated from wine and among bakers yeasts, respectively. The kinetics parameters results showed that the optimum alcohol releasing like 35% (g E/g S) and 30% (g E/g S) respectively from W6 and B1 be spread out at 40°C. The maximum volume of ethanol produced from peel mango by W6 and B1 were, respectively 13 and 10.1 g L ¯1 at the 120th.

  Saccharomyces is a potentially useful organism for the commercial production of ethanol as it is not capable of fermenting starch containing in the mango peel. To enhance this carbon source utilization and increase the rate of alcohol production, simultaneous saccharification and fermentation were conducted using Bacillus licheniformis and yeasts. The proposal of this research was to study amylasic activity, rate and amount of starch utilization and ethanol yields increasing several-fold in coculture due to the synergistic metabolic interactions between the species. The methods used, included: enzymatic hydrolysis with B. licheniformis and simultaneous saccharification and fermentation with S3 and A1. These two yeasts strains were isolated from wine and among local beer yeasts respectively. The enzymatic hydrolysis has allowed to obtain 78% (g g-1) of reducers sugars released. The maximum concentration of ethanol produced from peel mango by S3 and A1 during 5 days were, respectively 16 and 14.4 g L-1.

  The main goal of this study was to determine the phenol content, the antimicrobial and the antioxidant activities of acetone and water extracts from the rhizomes of Ampelocissus grantii (Baker) Planch (Vitaceae). The polyphenol content of extracts was determined colorimetrically using Folin-Ciocalteu method. The antioxidant activity of the same extracts was also screened using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method. The antimicrobial activity was performed by disc diffusion and broth microdilution assays against 9 reference bacterial strains including gram-negative and gram-positive bacteria and 1 fungal strain. The acetone extract exhibited the higher level of Total Polyphenol Contents (TPC) which correlated with strong antioxidant activity (IC50 = 10.87 μg mL-1 and AAI = 5.6) and antimicrobial activity. The polyphenol content of the acetone extract was 124.26 gallic acid equivalent/100 g (GAE/100 g), that of water extract was 74.25 GAE/100 g. The largest diameter of inhibition zone (DIZ) (15 mm) and the lowest Minimal Inhibitory Concentration (MIC) value (0.625 mg mL-1) were recorded with Enterococcus faecalis 10907 CIP and Bacillus subtilus ATCC 21332. This study is a scientific base on the use of this plant in traditional health cure system.

  The main goal of this study was to determine the phenol content, the antibacterial and the antioxidant activities of the three species of Lannea largely use in traditional medicine in Burkina Faso. The total phenolic and flavonoid contents of hydro alcoholic extract (70%V/V ethanol/distilled water) from the barks of Lannea acida, Lannea microcarpa and Lannea velutina (Anacardiaceae) were determined by the method of Folin Ciocalteu and AlCl3 by spectrophotometry. These extracts were tested for their antioxidant and antibacterial activities. Antioxidant activity was determined by the method of DPPH and compared with quercetin. Antibacterial activity was performed by disk diffusion and broth microdilution essays against nine reference bacterial strains including gram-positive and gram-negative bacteria. L.acida exhibited the highest total phenolic contents (40.55±0.26 g GAE/100 g) which correlated with better antioxidant activity (IC50 = 345.72±7.76 μg mL-1). Furthermore the highest content of total flavonoids (11.02±0.04 g QE/100 g) and the largest anti bacterial spectrum (7.82 μg mL-1≤MIC≤ 62.5 μg mL-1) were recorded with L.velutina. These results show that the barks of L. acida and L.velutina could be used respectively as a potential natural antioxidant and antibacterial agent.
