when cultures are grown on starch plates (which are usually nutrient agar with starch added) gram's iodine can be used later to turn the plate blue. If there is a clear(not blue area) around the culture than it consumes starch. its used to help identify what you have cultured.
What else can I help you with?
Why must use starch casein nitrate agar and what is the starch casein agar properties?
Starch casein nitrate agar is used to culture aerobic spore-forming bacteria, particularly Bacillus species. It promotes sporulation due to the presence of nitrates and starch as a carbon source. The properties of starch casein agar include supporting the growth of fastidious bacteria, promoting sporulation, and enabling the detection of extracellular enzyme production.
Why is starch phosphorylase not involved in vivo starch anabolism?
Starch phosphorylase is primarily involved in starch degradation by catalyzing the conversion of starch to glucose. In vivo starch anabolism involves the synthesis of starch molecules from glucose, which is carried out by enzymes like starch synthase and starch branching enzyme. Therefore, starch phosphorylase is not directly involved in the biosynthesis of starch in living systems.
Why do bacteria grow heavily on starch agar but don't produce alpha amylase?
Starch agar contains beef extract, soluble starch, distilled water, and agar. Beef agar allows a variety of microbes to grow on this agar. Only a handful of those numerous microbes can produce amylase hense they will grow but won't break down starch.
Where do plants store glucose in?
Plants store glucose in the form of starch. Starch is primarily stored in specialized plant structures called amyloplasts, which are commonly found in seeds, tubers, roots, and stems. When plants need energy, they can break down starch into glucose to fuel various cellular processes.
Is starch a monosaccharide, disaccharide, or polysaccharide?
Starch is a polysaccharide.
How would the results of the starch hydrolysis change if glucose was added to the medium?
Adding glucose to the starch hydrolysis medium would provide an additional readily available source of energy for the organisms present. This could potentially increase the growth rate and metabolism of those organisms, leading to a faster breakdown of starch into glucose. As a result, the rate of starch hydrolysis may be accelerated in the presence of glucose.
Starch reaction with iodine at room temperature in neutral acidic alkaline medium which colour is form?
I don't know about acidic or alkaline reactions, but in neutral conditions the reaction of iodine with starch is a dark purple color
Will starch diffuse if so in what direction?
Starch does not readily diffuse through cell membranes due to its large molecular size. However, in a solution, starch can diffuse in a gel-like medium, but this process is generally slow. If starch is placed in a solution with a lower concentration of starch, it may diffuse toward areas of lower concentration, but the movement is limited compared to smaller molecules. Overall, starch diffusion is minimal and highly dependent on the medium and conditions.
How do you sterilize starch casein agar medium?
Dear Friend You can autoclave this medium but be carefull about volume of media because in time of heating it overflows. I make about 300 cc medium in a 1L erlenmeyer.
What is significance of the starch?
when cultures are grown on starch plates (which are usually nutrient agar with starch added) gram's iodine can be used later to turn the plate blue. If there is a clear(not blue area) around the culture than it consumes starch. its used to help identify what you have cultured.
How will you know if starch is present?
Starch presence can be detected using iodine solution, which turns blue-black in the presence of starch. Alternatively, starch can also be detected by enzymatic tests such as the starch-iodine test or using a spectrophotometer to measure absorbance at a specific wavelength.
Why do we use iodine solution to test for starch and what is the significance of this chemical reaction in identifying the presence of starch?
Iodine solution is used to test for starch because it reacts with starch molecules to form a dark blue or black color. This chemical reaction is significant in identifying the presence of starch because it provides a visible and easily recognizable indication of the presence of starch in a substance.
When you cook starch almirol what type of colloids is obtained identify the disperse phase and the despesion medium?
SOLID

Which has the most starch 1 medium orange 1 cup of kidney beans 8 fluid ounces of milk or 4 ounces of meat?
1 cup of kidney beans has the most starch compared to 1 medium orange, 8 fluid ounces of milk, and 4 ounces of meat.
What is the significance of starch polysacchride?
Storage of food in plants. As starch is insoluble and compact, it is the most ideal form for storage in plants. For animals, starch is a source of carbohydrate. Therefore source of energy.
How is cassava starch used to make plastics?
Cassava Starch by itself: Best to buy a full resin from a resin manufacturer such as NatureWorks or Mater-Bi.
