Lignin As A Green Primary Antioxidant For Polypropylene
(Wiley-BlackwellHoboken, 2016)
Relevance of extractives and wood transformation products on the biodegradation of Pinus taeda by Ceriporiopsis subvermispora
(ELSEVIER SCI LTD, 2008)
Ceriporiopsis subvermispora is a promising white-rot fungus for biopulping. However, the underlying biochemistry involved in lignin removal and insignificant cellulose degradation by this species is not completely understood. ...
Technological advances and mechanistic basis for fungal biopulping
(ELSEVIER SCIENCE INC, 2008)
Biopulping fundamentals, technology and mechanisms are reviewed in this article. Mill evaluation of Eucalyptus grandis wood chips biotreated by Ceriporiopsis subvermispora on a 50-tonne pilot-plant demonstrated that ...
Characteristics and Applications of Bacterial Nanocellulose
(Central West Publishing, 2019)
There is an increasing demand for products made from renewable and sustainable non-petroleum based resources. Cellulose, the most abundant polymer on Earth, is renewable, biodegradable, as well as non-toxic. In nature, ...
Enzymes produced by soil fungi following microaerobic growth on lignocellulosic materials
(Humana Press IncTotowaEUA, 1999)
Cooperation in regional innovation networks among small and medium enterprises: Case study of a veterinary pharmaceutical company in Jalisco, Mexico
(1994)
Technical lignins derived from kraft, organosolv, soda, and ASAM pulping as well as a fermented lignosulfonate from a sodium sulfite process have been subjected to oxidative ammoniation (ammoxidation) aimed at producing ...
Resistência da madeira de Pinus taeda tratada termicamente ao ataque de fungo de podridão branca (Trametes versicolor)
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEngenharia FlorestalUTFPR, 2014-06-24)
Wood heat treatment can minimize damage by fungi, increasing the durability and dimensional stability of wood. These treatments consist in heating the wood to high temperatures, promoting chemical changes of the primary ...
KRAFT AND KRAFT/AQ PULPING FROM PREHIDROLYZED WOOD OF HYBRID Eucalyptus urophylla x grandis
(Centro Pesquisas Florestais, Ufsm, 2016-10-01)
The wood of the gender Eucalyptus occupies a prominence place among other cellulose sources due to its chemical composition, its low cost, abundance and availability. Among the chemical pulping processes, kraft process is ...
The gut microbiome of the neotropical beetle Veturius sp. (coleoptera: passalidae): structure, composition and geneticpotential for cellulose degradation
(2020)
The global carbon cycle is responsible for maintaining the carbon dioxide and methane concentration in the atmosphere, influencing the weather and ocean acidification. Herbivores play an important role in the carbon cycle. ...
