Ulva Algae Extract for Antibacterial Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing resistance of bacteria, such as Staphylococcus aureus, to antimicrobial agents has led to a need for alternative treatments, particularly in livestock and human health, where traditional antibiotics are ineffective, and there is a requirement for a sustainable solution to bacterial infections.
Innovation Solution
An extract of green algae from the Ulvales order, specifically containing sulfated and non-sulfated polyanionic polysaccharides less than 50 kDa, including mannose, arabinose, galactose, glucose, rhamnose, xylose, and glucuronic acid, is used to prevent and treat bacterial infections by inhibiting bacterial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antibiotics are used to treat bacterial infections, then bacterial growth is inhibited, but bacterial resistance develops and treatment effectiveness decreases
Solution Approach 1:
The patent extracts and utilizes specific polysaccharide components (sulfated and non-sulfated polyanionic polysaccharides with molecular weight <50 kDa) from green algae Ulva. These extracted active ingredients exhibit antibacterial activity against resistant bacterial strains, providing an alternative treatment mechanism that bypasses conventional antibiotic resistance pathways.
Solution Approach 2:
The invention changes the chemical parameters of the antibacterial agent by using polysaccharides with specific molecular weight characteristics (<50 kDa) and specific monosaccharide compositions (mannose, arabinose, galactose, glucose, rhamnose, xylose, and glucuronic acid). These parameter specifications ensure effective antibacterial activity while avoiding resistance development.
2Quantity of substance
If traditional antibiotic production methods are used, then antibiotics are effectively produced, but complex production processes with multiple steps are required
Solution Approach 1:
The patent utilizes the natural biosynthetic capabilities of green algae Ulva to produce the active polysaccharide components. The algae self-produce the antibacterial substances through their metabolic processes, eliminating the need for complex multi-step chemical synthesis or extraction procedures required by traditional antibiotic production.
