Agar-Agar From CONFERVOIDES SEAWEED GRACILARIA. The main ingredients for sulfuric acid galacitiol together fat. The goods have made for strip, some for powder. AGAR characteristic is its most use of low-freezing and melting point of difference between temperature. It should be in the water heated to 95 °C and then began to melt, the solution temperature melting to 40 °C to then began to set, so it is made of solid medium concreting best. Using agar-agar preparation, and it can be used to the solid culture medium of high temperature melting, and not in training before solidification vaccination, will not be will cultivate things very hot dead. Therefore, AGAR medium of biological preparation is the most widely used a coagulate agent. AGAR concentrations, usually is 1 to 1.5% of the liquid culture.Natural Agar-Agar is used in producing a firm, clear jelly and is rich in iodine and trace minerals and has mildly laxative properties.
