Advantages and disadvantages of agar solid-phase method

Advantages are convenient operation, simple synthesis process, uniform particle size, and controllable strength, less pollution, and at the same time can avoid or reduce the liquid phase is easy to appear in the hard agglomeration phenomenon, low cost. The disadvantage is that the composition is not easy to be uniform, the particles are easy to be agglomerated, and the particle diameter distribution is wide.

In the general culture temperature of the solid state of the medium are called solid medium. In the liquid medium add 1.5% to 2.0% of the agar, heated to 100 ℃ to dissolve, 40 ℃ cooling and solidification, so that it becomes a solid state that is the solid medium.
