- The solution was graded as incorrect in my homework. Is there another option for this question?True or false Explain your answer To observe the Bacterial species E. coli with bright field microscopy, you will have to stain the cells.Instead of Molisch's test, what specific test can be used to detect the presence of pentose sugar? Write the procedure
- The amount of phytomenadione contained in a O.2 mL ampoule of 10 * .mg/mL solutionTrue or False Galactose gives a positive result with Benedict’s test faster than lactose due to the acidity of the reagent used.TRUE FALSE Keller-Killiani Test - Involves color reaction of the sugar 2- deoxyhexose Salkowski Test - The upper layer turns yellow with green fluorescence Liebermann-Burchard Test - Acetic anhydride reacts with the aliphatic hydrocarbon. Keller-Killiani Test - Color change results to reddish brown that turns into violet or purple Liebermann-Burchard Test - Color change is due to increasing conjugation of the double bond in adjacent fused ring Salkowski Test - The chloroform layer turns red. Liebermann-Burchard Test - Chloroform was added to react with sulfuric acid. Liebermann-Burchard Test - Must observe the color right away because it happens in a very short period of time. Salkowski Test - Involves the reagents chloroform, sulfuric acid and acetic anhydride Liebermann-Burchard Test - Reaction involved is esterification.
- mixed micron cuboidal shaped cells within the stronger paste (F127) and the physical/biochemical process that occurs during the gelationNow prepare a 500 ml media having ¼ strength MS with 5mM BAP, 5.5 mg/l Kn and coconut water 10%. Stocks are MS Macro 10X, micro 20X, FeEDTA 10X, Organic 100X, BAP and Kn 5gm/100ml. If you need anything else then you add accordingly. BAP has a MW of 225.3. Sucrose and Myo-inositol is not mentioned in the question. These you need to add. Consistency of the medium is also mentioned.Is there a possibility for lactose to give a positive Mucic Acid test?
