Abstract

Oligosaccharins are natural polysaccharides and oligosaccharides occurring as part of cell walls of plants and microorganisms such as fungi; however, main sources of raw materials for its large scale preparation are by products from agriculture and wasted crustacean exoskeletons from fishing industry. They have potential agricultural applications since they promote germination
and plant growth, enhance crop yields and benefit symbiosis
in leguminous. A great number of studies demonstrate crop
protection by oligosaccharins against biotic and abiotic
stress. Some oligosaccharins, such as chitosans, perform
direct antimicrobial activity, this fact reinforce their
application as protective agent of agricultural commodities
quality. There are several international commercial products
based on these macromolecules that bearing also, as an
additional valor, the innocuous and biodegradable features
of these compounds. The Group of Bioactive Products
(GPB) from INCA has developed several oligosaccharins
based products that constitute national alternatives to agroproducts as plant growth regulators, enhancers of crop yields,
plant protecting agents against biotic and abiotic stress and
new type of biofertilizers for biological nitrogen fixation in
leguminous.
