Agrobiotechnology in turfgrass - Exopolysaccharides

Most bacteria produce exopolysaccharides that have a positive impact on agriculture. Exopolysaccharides are organic molecules that have many functionalities for industry, including, of course, agriculture.

Polysaccharides exuded by micro-organisms help the success of the plant cycle under adverse conditions.

As we have explained in previous posts, microorganisms play a key role in soil productivity and long-term use. The effects of polysaccharides on crops are not well studied, but there are clear indications of the positive effect of these products. They are considered to improve several soil properties, such as soil structural stabilisation, water retention or retention of plant-accessible nutrients.

For example, nitrogenase has a high capacity to oxidise, and polysaccharides slow down this deterioration. Sodium water stress is reduced as these exopolysaccharides also help to balance osmotic pressure.

In industry, exopolysaccharides are highly valued, for example the alginate is a widely used exopolysaccharide.

Many bacteria are able to exude polysaccharides, e.g. the genus Rhizopus, Bradyrhizobium or gender Paenibacillus are bacteria that have a significant impact on production.

The potential for improvement for disease resistance, growth promotion, or improving overall soil health is there, but there is still much to be done. study to make more concrete assertions.

In summary, exopolysaccharides are credited with improving soil structure and increasing PGPR secretion. They improve the colloidal structure of the soil and are enhancers of the positive effects of symbiotic microorganisms.
