2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.
Abstract
Lignocellulosic ethanol production process, pretreatment, saccharification, fermentation, purification is divided into four steps.
The goal of the preprocessing step, after separating from the other ingredients, such as lignin and cellulose, which have the characteristics of hard and complex structures belonging to the upstream process, the microorganisms in the process of sacc

-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.
