Characterization of Self-Growing Biomaterials Made of Fungal Mycelium and Various Lignocellulose-Containing Ingredients
2022
In this study, novel blends of mycelium biocomposites (MB) were developed. Various combinations of birch sawdust and hemp shives with birch bark (BB) and wheat bran (WB) additives were inoculated with basidiomycete Trametes versicolor to produce self-growing biomaterials. MB were characterized according to mycelial biomass increment in final samples, changes in chemical composition, elemental (C, H, N) analyses, granulometry of substrates, water-related and mechanical properties, as well as mold resistance and biodegradability. The mycelial biomass in manufactured MB increased by ~100% and ~50% in hemp and sawdust substrates, respectively. The lignocellulose ingredients during fungal growth…

USE OF BIODEGRADABLE POLYMERS FOR FOAM EXTRUSION

Toward the Decarbonization of Plastic: Monopolymer Blend of Virgin and Recycled Bio-Based, Biodegradable Polymer.
2022
Decarbonization of plastics is based on two main pillars: bio-based polymers and recycling. Mechanical recycling of biodegradable polymers could improve the social, economic and environmental impact of the use of these materials. In this regard, the aim of this study was to investigate whether concentrations of the same recycled biopolymer could significantly affect the rheological and mechanical properties of biodegradable monopolymer blends. Monopolymer blends are blends made of the same polymers, virgin and recycled. A sample of commercially available biodegradable blend was reprocessed in a single-screw extruder until two extrusion cycles were completed. These samples were exposed to gr…
Photo-Oxidative and Soil Burial Degradation of Irrigation Tubes Based on Biodegradable Polymer Blends
2019
: Irrigation tubes based on biodegradable polymers were prepared via an extrusion-drawing process by Irritec and compared to conventional pipes made of high-density polyethylene (HDPE). A commercial polylactide/poly (butyleneadipate-co-butyleneterephthalate) (PLA/PBAT) blend (Bio-Flex®

Biodiversity of organophosphorus-degrading bacteria isolated from agricultural soils
2009
Organophosphorus (OP) insecticides are used all over the world for crop protection. Although OPs are less persistent than organochlorine pesticides, they still constitute an environmental risk thus increasing the social concern about their levels in soils, surface and ground waters. Biodegradation by microorganisms is primarily responsible for elimination of the OP insecticides released to the environment. In the present study the OP degrading potential of agricultural soils with different agronomic history was investigated. Using enrichment cultures, with parathion or dimethoate as the sole C and energy sources, 47 bacterial isolates were obtained from OPs contaminated and pristine agricul…

Micēlijsēņu pielietojuma iespējas celulozes un celulozes acetāta biodegradēšanai
2021
Signe Vadone (2021): Micēlijsēņu pielietojuma iespējas celulozes un celulozes acetāta biodegradēšanai. Darbā salīdzināta 12 dažādu micēlijsēņu augšana uz dažādiem celulozes (C) un celulozes acetāta (CA) paraugiem – smēķētiem un nesmēķētiem cigarešu filtriem un to ārējiem apvalkiem, kā arī rūpnieciski neapstrādātiem celulozes un celulozes acetāta paraugiem. Veikta arī CA filtru inkubēšana augsnē kopā ar labāk augušajām micēlijsēnēm. Novērtētas micēlijsēņu augšanas tendences un cigarešu filtru masas un CA struktūras izmaiņas cigarešu filtru plastificējošās saistvielas – glicerīna triacetāta ietekmē. Noskaidrots, ka vislabāk uz cigarešu filtriem aug Aspergillus niger 137.3, Stachybotrys charta…
