Phytochemical importance and utilization potential of grape residue from wine production
Grapes are placed at a distinct position, both in the economy and at nutritional and phytochemical levels. The number of studies performed aimed at identifying the various bioactive compounds of grapes, how their cellular structures are linked, efficient methods of extraction and its effect on human health are rather relevant. The use of grapes for wine production is a worldwide activity, therefore a great quantity of...

Plant physiological stimulation by seeds salt priming in maize (Zea mays): Prospect for salt tolerance
Nowadays to lessen the influence of salinity on crop performances such as germination, seedling growth and yield, several actions are undertaken; for example the use of different priming methods, antioxidants and plant growth controllers. Seed priming, best fits in this study on maize crop and is controlled by hydration process followed by re-drying that allows pre-germination which enhanced metabolic activities to...

Use of biosurfactant surfactin produced from cassava wastewater for anaerobic treatment of effluent from a poultry slaughterhouse
The use of a biosurfactant surfactin produced by Bacillus subtilis LB5a in cassava growth medium (cassava wastewater) was evaluated to treat anaerobically, the effluent from a poultry slaughterhouse. During the effluent pretreatment, effects of surfactin concentration factors were evaluated, considering the ones which were superior and below its critical micelle concentration (CMC = 28 mg L-1): 6, 13, 27, 31, 48, 73 and...

Effect of activators and inhibitors on extracellular thermostable alkaline protease isolated from Bacillus subtilis obtained from eastern province of Saudi Arabia
Alkaline proteases need some ions to achieve highest activity. These metallic ions help in, enzyme stability and activity through its thermal stability at high degrees. This protects the enzyme from being destroyed by heat. The results show that the ideal condition for enzyme activity was, using Mn2+ ions as the activator with 1112.5 U/ml activity, while MgSO4.7H2O has lower effectiveness of an enzyme activity...

Optimization of biomass and glucoamylase production by Candida famata using response surface methodology
Glucoamylase is among the most important enzymes in biotechnology. The present study aims to determine better conditions for growth and glucoamylase productivity by Candida famata and to reduce the overall cost of the medium using central composite design (CCD) with one central point and response surface methodology. A three-level central composite design (CCD) factorial design based was employed to obtain optimal...

Selection of filamentous fungi producing lipases from residual waters of slaughterhouses
The exploration and use of lipases produced by microorganisms are in line with societal concerns since they provide clean development options within the standards of environmental sustainability. The objective of this work was therefore to isolate microorganisms with the potential of producing lipases, which could be used in the waste water treatment systems of slaughterhouse units. Waste water samples were collected...
