Solution Overview
Problem
Existing technologies lack efficient methods for hydrolyzing carbohydrates, particularly polysaccharides, in high salinity and temperature conditions, which are crucial for biorefinery processes using marine biomass.
Innovation Solution
A novel halophilic and halotolerant bacterium, Alkalihalobacillus sp., is identified from the gut of a sea urchin, capable of producing and utilizing various carbohydrate-active enzymes (CAZymes) to degrade starch into monosaccharides and nucleotide forms, even under high saline and temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional hydrolysis methods are used, then carbohydrate degradation can occur, but the process is inefficient under high salinity and temperature conditions
Solution Approach 1:
The patent utilizes extremophilic microorganisms that have adapted their enzymatic systems to function optimally under high salinity and temperature conditions. The enzymes produced by these microorganisms have altered structural parameters that confer stability and catalytic activity in extreme environments, resolving the contradiction between maintaining process stability and achieving high hydrolysis efficiency under harsh conditions
Solution Approach 2:
The patent employs microorganisms that can be easily cultivated and discarded after a single use cycle. These microorganisms are grown in controlled conditions, harvested for their enzymatic activity, and then discarded, eliminating the need for complex purification and reuse infrastructure while maintaining high productivity under extreme conditions
2Quantity of substance
If marine biomass is used for biorefinery, then bioenergy production potential increases, but the lack of efficient hydrolysis methods limits the process
Solution Approach 1:
The patent employs microorganisms that naturally possess the enzymatic machinery required to degrade marine biomass carbohydrates. These self-sufficient microorganisms can directly utilize marine biomass as their carbon source and convert it into bioenergy products without requiring external addition of complex enzyme cocktails or pre-treatment processes, thereby simplifying manufacturing while maximizing bioenergy potential
Solution Approach 2:
The extremophilic microorganisms described in the patent possess multiple functional capabilities: they can tolerate and thrive in high salinity and temperature conditions, secrete various carbohydrate-active enzymes for biomass degradation, and convert degraded products into bioenergy. This multi-functionality eliminates the need for separate process stages and simplifies the overall biorefinery operation
