Abstract
Prekomjerna uporaba sintetičkih materijala i posljedice njihove trajnosti u okolišu potaknula je razvoj novih, održivih materijala dobivenih iz lignocelulozne biomase. Celulozna vlakna dobivena iz slame žitarica imaju potencijal za različite primjene, uključujući proizvodnju papira i tekstila. Cilj ovog istraživanja bio je ispitati biorazgradivosti i ekotoksičnost neotisnutih i otisnutih papira s celuloznom pulpom slame žitarica. Pokus biorazgradnje papira proveden je u uzorku vrtnog tla s dodatkom suspenzije mješovite kulture bakterije Pseudomonas aeruginosa i plijesni Trichoderma sp., pri čemu su praćeni gubitci u masi te promjene u strukturi papira optičkim mikroskopom. Dobiveni rezultati ukazuju da se papir na koji nije otisnuta boja bolje biorazgradio od otisnutog papira. Otisnuti i neotisnuti papiri nisu se pokazali ekotoksičnim prema vodenoj leći Lemna minor.
Abstract (english)
The excessive use of synthetic materials and their long-term impact on the environment have spurred the development of new, sustainable materials sourced from lignocellulosic biomass. Cellulose fibers obtained from cereal straw have emerged as a promising candidate for various applications, including paper and textile manufacturing. This study aimed to assess the biodegradability and ecotoxicity of papers with cereal straw pulp, both printed and unprinted. Biodegradation experiments were conducted using a garden soil sample supplemented with a mixed culture of bacteria Pseudomonas aeruginosa and fungi Trichoderma sp. The experiments monitored mass losses and structural changes in the paper using a light microscope. The results indicate that unprinted paper exhibited better biodegradability compared to printed paper. Moreover, neither printed nor unprinted paper showed ecotoxic effects on Lemna minor.
