Result Soil was found to be acidic in nature as pH was recorded in the range of 5.7±0.260 C. The mean temperature during sampling month varied from 27.8+0.830C. The moisture content of the soil was 17 ± 1 % during studies (Table-1). From each rhizospheric soil‚ a single well distinct colony with different morphological characters was preferred for studies. On the basis of dissimilar morphological characters of the colonies‚ total twenty seven rhizobacterial isolates were isolated 7 from Coriander

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

Cesar Bizarroque Wesam Daker Bio 1107k-11 10/25/14 How pH levels impact tyrosinase activity Abstract: The purpose of our research utilizing the different pH levels was to test how a specific pH level would impact tyrosinase activity. First we added 4.0 mL of pH in each corresponding test tube and then added 0.5 mL of substrate (catechol) into each test tube. In the instructions it says to apply your 0.5 mL of tyrosinase (potato extract) as well but you have to blank the spectrophotometer before

Hypothesis: If I increase the concentration of NaOH from 0.5M to 1M‚ then I will see the temperature slope increase in the reaction with an increased concentration because with an increase of moles‚ the particles will be colliding more often‚ therefore increasing the probability that the proper energy and alignment will occur to create more collisions in the same amount of time. Methods: List of Materials: • 110 mL of NaOH at 1 M (10 mL per run) • 110 mL of NaOH at 0.5 M (10 mL per run) • 220 mL

As for the results of our tests‚ we came up with interesting findings. For the first test we conducted‚ pH‚ we came up with statistically significant results. Our p-value was .002‚ well below the .05 threshold. The control group’s mean pH was 6.65‚ whereas the experimental group’s was 6.46. This resulted in a change in pH of .19‚ making the water more acidic. As for the Q-values‚ the control group’s had a Q-value of 81 and the experimental had a Q-value of 75‚ that’s a decrease of 6‚ a significant
