Recently, Prof. Dr. Tong Kim Thuan and scientists from the Institute of Biotechnology (Vietnam Academy of Science and Technology) have studied using microorganisms with mucous membranes to create moisture for the soil.

More importantly, these yeast strains have been isolated and produced into small-scale commodities, and at the same time, tested and effectively supported for the greening of bare hills.

This biological product is called Lipomycin - M , because its main ingredient is the Lipomyces PT7.1 yeast isolated from bare land of Ha Hoa district (Phu Tho). Their advantages are the ability to form mucous membranes in dry soil conditions and grow at high temperatures.

Taking advantage of these properties, the team put them into culture medium with proper temperature and humidity. During fermentation for 5 days, yeast biomass was removed, added preservatives and put into drying, packing.

Using this preparation is also very simple: just apply Lipomycin - M around the stump with a moderate dose, then fill up a layer of soil. For dry areas without irrigation water, they must be applied in the late dry season or early rainy season. Under no rain conditions, yeast grows slowly and can survive throughout the dry season as spore cysts.

When the rainy season comes, spores sprout and proliferate mucous membranes to reduce the evaporation, increase the water holding capacity of the soil, and maintain soil moisture in the absence of water conditions. Irrigation long time, contribute to improving the survival rate of plants.

In particular, if this composition is mixed with NPK fertilizer, the moisturizing effect increases by 15 - 30% compared to separate application. In addition to the above advantages, Lipomycin - M microbiology also has many other beneficial properties such as no harm to soil microorganisms, land animals as well as to the ecological environment, and not harmful. for plants.

Mr. Tong Kim Thuan said that the Institute of Biotechnology now needs investment to produce on a large scale, increase the efficiency of serving farmers, or transfer technology to dry areas.
