Artyku³ jest przegl¹dem dorobku pracowników IBWCH i partnerów projektów w zakresie zawartej w tytule tematyki. Wskazano mo¿liwy zakres zastosowañ biomasy, nies³usznie czêsto uznawanej za produkt odpadowy, maj¹cy wartooeae jedynie energetyczn¹. Do materia³ów najczêoeciej pozyskiwanych z biomasy nale¿¹: celuloza ze s³omy zbó¿, lioeci i ³odyg kukurydzy czy ³upin orzechów, keratyna z ptasich piór, chityna i chitozan z pancerzy skorupiaków. Te naturalne polimery s³u¿¹ jako dodatek do bazowych polimerów, np. PE, PP, zwiêkszaj¹cy wytrzyma³ooeae (celuloza), ognioodpornooeae i izolacyjnooeae akustyczn¹ (keratyna) lub te¿ ch³onnooeae i bakteriostatycznooeae (chitozan, chityna) biokompozytów wytworzonych z ich udzia³em.
Biopolymers from a group of polysaccharides are used in treatments enhancing sowing material of crops due to their physical and chemical properties, susceptibility to chemical modification, biodegradability and high bioactivity. Natural polymers, such as: chitosan, alginian, celulose, galaktoglucomannans, lignin and gellan gum, can be used as binders in seed coating or carriers of active substances and microorganisms. Moreover, biopolymers contained in the seed coatings and seed dressings can protect germinating seeds from unfavorable influence of environment and pathogens.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
