Gram positive bacterias have a cell wall which will stain in violet color. Gram negative bacterias, howâ¦ever, have an extra layer of cell wall around them which prevents the cell wall from being dyed. These gram negative bacterias will need an additional stain called safranin to make the bacterias redish color.
Grain products like bread, cereal, rice, and pasta are good for you. They are important sources of vitamins and minerals. Breads, cereals, rice, and pasta are also good sources of carbohydrates like starch and fiber. Many people think that starchy foods like breads, rice and pasta are fattening.
The whole grain is rich in protein and fiber, and just one serving of this pasta dishes up a quarter of the dayâs phosphorus (a nutrient thatâs typically only found in milk and meat) and 80 percent of the dayâs manganese, an essential nutrient that helps the body process cholesterol, carbs and proteins.
