AB The development of biological strategies to obtain new high-added value biopolymersfrom lignocellulosic biomass is a current challenge for scientific community. This study evaluatesthe biodegradability and ecotoxicity of new formulated oleogels obtained from fermentedagricultural residues with Streptomyces, previously reported to show improved rheological andtribological characteristics compared to commercial mineral lubricants. Both new oleogels exhibitedhigher biodegradation rates than the commercial grease. Classical ecotoxicological bioassays usingeukaryotic organisms (Lactuca sativa, Caenorhabditis elegans) showed that the toxic impact of the producedbio-lubricants was almost negligible and comparable to the commercial grease for the targetorganisms. In addition, high throughput molecular techniques using emerging next-generation DNAsequencingtechnologies (NGS) were applied to study the structural changes of lubricant-exposedmicrobial populations of a standard soil. Results obtained showed that disposal of biomass-basedlubricants in the soil environment did not substantially modify the structure and phylogenetic compositionof the microbiome. These findings point out the feasibility and sustainability, in terms ofbiodegradability and eco-safety, of the new bio-lubricants in comparison with commercial mineralgreases. This technology entails a promising biological strategy to replace fossil and non-renewableraw materials as well as to obtain useful biopolymers from agricultural residues with potential forlarge-scale applications.
