Algal Polysaccharides—Marine Active Sources for Green Agriculture

Algal polysaccharides are the core components of algal cell walls. With City Max Group’s three-stage enzymatic hydrolysis technology, they are converted into highly active brown algal oligosaccharides (AOS). A natural plant immune elicitor, AOS boosts antioxidant enzyme activity, regulates endogenous hormones, enhances stress tolerance, and promotes photosynthesis and dry matter accumulation to deliver stable yields and better crop quality. The product SEAMAX, based on this technology, combines three types of algae with outstanding activity and remarkable efficacy.

Algal polysaccharides—particularly alginate—are key components of algal cell walls, possessing excellent gelation, ion exchange, and hydrophilic properties. They serve as important biostimulants in modern green agriculture. However, due to their high degree of polymerization and large molecular weight, their direct utilization efficiency by crops is limited. CityMax Group’s independently developed three-stage enzymatic hydrolysis technology effectively decomposes large polysaccharide molecules into highly active brown algal oligosaccharides (AOS), significantly enhancing biological activity and enabling faster absorption and more consistent effects.

 Ⅰ. Brown Algal Oligosaccharides—Natural Regulators of Crop Growth

Brown algae oligosaccharides are natural plant immune inducers that regulate endogenous hormone metabolism and activate the plant's antioxidant enzyme system, systematically modulating crop growth in terms of stress resistance, vigor, and yield, thereby establishing a practical pathway for applying marine resources to green agriculture:

1. Enhanced stress tolerance: Increases the activity of antioxidant enzymes such as SOD, POD, and CAT; stabilizes cell wall structure under salt stress, promotes soluble sugar synthesis in low-temperature conditions, reduces membrane lipid peroxidation damage, and significantly improves crop resilience.

2. Balanced endogenous hormones: Elevates auxin and cytokinin levels in roots, suppresses excessive accumulation of growth-inhibiting substances like jasmonic acid, and coordinates balanced growth between aboveground stems and leaves and underground root systems.

3. Improved quality and yield: It activates plants’innate defense systems, raises photosynthetic efficiency and accelerates the synthesis and accumulation of dry matter, so as to achieve stable yield and superior crop quality.

 Ⅱ. CityMax Brown Algae Oligosaccharides—A Quality Closed Loop from Raw Materials to Processing

SEAMAX employs CityMax’s proprietary MAXTSEH three-stage enzymatic hydrolysis process, meticulously selecting Irish seaweed, South African kelp and horsetail algae to achieve a scientifically balanced ‘triple-algae blend’. This process efficiently releases multiple active components including algal polysaccharides, mannitol and phenolic compounds, significantly enhancing crop absorption rates and effectively improving physiological responses under adverse conditions. The core functions of SEAMAX lie in promoting root development, enhancing photosynthesis, boosting stress resistance, and effectively improving fruit set and fruit quality. It is widely applicable to high-value cash crops such as tomatoes, peppers, melons, grapes, and strawberries.
