Production of Alcohol01:27

Production of Alcohol

Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
Production of Organic Acids01:25

Production of Organic Acids

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Area of Science:

  • Biomass processing
  • Biorefinery operations
  • Sustainable chemistry

Background:

  • Efficient feedstock processing is crucial for biorefinery capacity.
  • Current methods for corn stover slurries are limited to 150 g/L due to flowability issues.
  • Lignocellulosic biomass requires effective pretreatment for biofuel production.

Purpose of the Study:

  • To develop a novel strategy for liquefying corn stover at higher solids concentrations.
  • To improve the operability and efficiency of biorefineries by enhancing slurry transport.
  • To reduce the inhibitory effects of biomass components on enzymatic hydrolysis.

Main Methods:

  • Cooking corn stover with maleic acid (40 mM) at 150°C.
  • Enzymatic modification for 6 hours using 1 FPU (2.2 mg protein)/g solids.
  • Measuring yield stress to assess slurry flowability.

Main Results:

  • Achieved corn stover liquefaction at 300 g/L solids concentration.
  • Reduced slurry yield stress from 6806 Pa (untreated) to 171 Pa (6h) and 58 Pa (48h).
  • Minimized inhibitory effects of xylo-oligomers on hydrolytic enzymes.

Conclusions:

  • The new strategy enables pumping of high-concentration lignocellulosic slurries into biorefinery reactors.
  • This approach significantly enhances biorefinery operability and design capacity.
  • The method overcomes limitations of current biomass slurry preparation techniques.
