The barley plants grew excellently, but in the control experiment, in which the pea seed was not inocu- lated, they failed to grow. It was also found that barley, as well as peas, grew exceedingly well right up to the flowering or fruiting stage when they were fed with an aqueous ...
In the experiment, the enzyme amylase acts on starch to produce reducing sugars that react with dinitrosalicylic acid to produce a brown colored product. The resultant color is estimated using colorimeter and a progress curve is plotted. Enzyme activity can be calculated by the graph. The specific...
Within the experimentation process it will be important to identify the independent variable, the dependent variable, and standardized variables for each experiment. Part 1: Observe the Effects of Catalase Procedure Obtain two test tubes and label one as A and one as B. Use your ruler to ...

Outline the effect of temperature on the activity of urease enzyme. [2 marks] State one factor that would need to be controlled in this experiment. [1 mark] 2. The enzyme amylase was extracted from the digestive system of horses and added to whole cereal grains (seeds) in test tubes at...
(CFU) and biomass areal density. The biofilms were grown at pH levels of 5 and 7, with three different cellulase concentrations: 9.4, 37.6, and 75.2 units/mL. A control experiment with inactivated cellulase was also included. The findings demonstrated that cellulase effectively reduced biomass ...
A study was conducted to explore the effectiveness of cellulase in inhibiting biofilm formation byP. aeruginosa, a pathogen frequently found in medical implants. In this experiment, a biofilm was cultivated on glass slides within a parallel flow chamber for four days, using glucose as the nutrient...
(2006) in soil contaminated with acetamiprid, Wyszkowska and Kucharski (2004) in a study of Trifl urotox 250 EC, and by Wyszkowska (2002) in an experiment with Treflan 460 EC. Bacmaga et al. (2012) observed a positive effect of the Aurora 40 WG herbicide containing carfentrazone-ethyl...
After maize starch being treated by β -amylase for 4h,the highest SDS amount of 13.95% was gained when transglucosidase continued to treat for 24h,the average chain length was 12.58,and branch density was 7.95% . The experiment proved that dual -enzymes treatment could improve the ...
For multi-enzyme encapsulation, a fluorescence labeling experiment was performed as described in a previous study [35]. To prepare FITC, 2 mg was dissolved in 2 mL of dimethyl sulfoxide (DMSO) to achieve a uniform solution. The solution was protected from light by wrapping it in foil to mai...
