Abstract

Aktinobakterije predstavljaju jednu od najvećih skupina prokariotskih mikroorganizama unutar domene Eubacteria. Njihova specifičnost ogleda se u tome što dijele karakteristike i bakterija i gljiva, a ujedno pokazuju djelotvoran učinak na produktivnost poljoprivrednih usjeva. S obzirom da je prekomjerna upotreba mineralnih gnojiva i pesticida u poljoprivrednoj proizvodnji rezultirala negativnim posljedicama za cjelokupni okoliš, javila se potreba za pronalaskom alternativnih strategija, a rješenje se ogleda u održivoj poljoprivredi. Održiva poljoprivredna proizvodnja osigurava visoke prinose i hranu proizvedenu na ekološki prihvatljiv način pri čemu određeni mikroorganizmi mogu imati značajnu ulogu u održavanju stabilnosti i produktivnosti agroekosustava. Među njima je sve veća pažnja usmjerena na PGP aktinobakterije (engl. Plant Growth Promoting Actinobacteria), obzirom da posjeduju sposobnost promicanja biljnog rasta te sudjeluju u biološkoj kontroli biljnih patogena, a to se ostvaruje pomoću njihovih direktnih i indirektnih mehanizama. Primjena PGP aktinobakterija može smanjiti ili potpuno zamijeniti upotrebu mineralnih gnojiva i pesticida, stoga predstavljaju veliki potencijal za razvoj održive poljoprivrede.

Abstract (english)

Actinobacteria represent one of the largest groups of prokaryotic microorganisms within the Eubacteria domain. Their specificity is reflected in the fact that they share the characteristics of both bacteria and fungi, and at the same time show a beneficial effect on agricultural crop productivity. Considering that the excessive use of mineral fertilizers and pesticides in agricultural production has resulted in negative consequences for the overall environment, there is a need to find alternative strategies, and the solution lies in sustainable agriculture. Sustainable agricultural production provides high yields and food produced in an environmentally friendly way where certain microorganisms can play a significant role in maintaining the stability and productivity of agroecosystems. Among them, there is a prime focus on PGP actinobacteria (Plant Growth Promoting Actinobacteria), since they have the ability to promote plant growth and participate in the biological control of plant pathogens, and this is accomplished through their direct and indirect mechanisms. The application of PGP actinobacteria can reduce or completely replace the use of mineral fertilizers and pesticides, therefore they represent a great potential for the development of sustainable agriculture.
