Q:The effect of inorganic salt medium and the difference with enrichment medium
The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
Q:What is the difference between "organic salt" and "inorganic salt"?
Organic salts are organic acids with alkali (carboxylic acid) occurs in the reaction of the salt is called organic salt.
Q:What kinds of inorganic salts are required for plant growth
Only 70 kinds of chemical elements can be detected in plants, but only 16 kinds of essential nutrient elements are needed for the growth and development of internationally recognized higher plants. They are carbon (C), hydrogen (H), oxygen (O), nitrogen (Fe), magnesium (Mg), sulfur (S), iron (Fe), boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo) and chlorine (C1), which can be divided into large nutrient elements, medium nutrient elements and micronutrient elements according to their requirements, such as carbon, hydrogen, oxygen and nitrogen Phosphorus, potassium, copper, zinc, molybdenum and chlorine.Now there are scholars that nickel (Ni) is the first 17 kinds of essential nutrients.
Q:What substances can detect inorganic salts
Looks like, a lot of inorganic salt ah, this, I suggest you clear the concept of inorganic salt under you.
Q:How to isolate the effects of inorganic salts on enzyme solubility
The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.
Q:Sodium bicarbonate is not an inorganic salt
Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt
Q:Does the apple contain inorganic salts and vitamins?
Yes, the fruit is rich in these two nutrients, especially apples
Q:What is the inorganic salt, is not the organic salt and is not the inorganic salt
There is no concept of organic salt inorganic salt inorganic salts in the class of chanting
Q:Does the plant absorb some of the inorganic salt?
Plants absorb moisture and absorb inorganic salts are two relatively independent processes.
Q:How does inorganic salts maintain osmotic pressure and pH
Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
