Lignin is one of the most abundant and recalcitrant natural polymers. Consequently, lignin degradation is important for completing the carbon cycle in forest ecosystems and a central challenge towards more environmentally-friendly and economically performing second-generation lignocellulosic-based biorefineries.
Recently, there has been a considerable interest for the production of renewable energy from lignocellulosic biomass which presents several advantages. It is, however, a technological challenge because of the difficulty to hydrolyze lignin contained in this biomass. This limitation can be overcome by pretreatments. Among them, low-cost fungal pretreatments are attractive. This study focuses on the selection of a fungal strain, in order to increase methane production from wheat straw.
Exploration of fungal biodiversity for the deconstruction of lignocellulosic biomass and the implementation of new biosynthetic pathways for green chemistry. European Union and Sustainable Development: Challenges and Prospects
Following the development of new applications of pilot plant scale extraction and formulation processes for natural active bioproducts obtained from various under-utilized tropical plants and herbs, we have manufactured water-extracts from Delonix regia flowers, grown in Ivory Coast. These extracts, which contain polyphenols, are traditionally home made and used as healthy bioproducts. They are reddish-coloured due to the presence of anthocyanins.
With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities.
Microbial mannanases are biotechnologically important enzymes since they target the hydrolysis of hemicellulosic polysaccharides of softwood biomass into simple molecules like manno-oligosaccharides and mannose. In this study, we have implemented a strategy of molecular engineering in the yeast Yarrowia lipolytica to improve the specific activity of two fungal endo-mannanases, PaMan5A and PaMan26A, which belong to the glycoside hydrolase (GH) families GH5 and GH26, respectively.
Ganoderma lucidum is a widely used medicinal macrofungus in traditional Chinese medicine that creates a diverse set of bioactive compounds. Here we report its 43.3-Mb genome, encoding 16,113 predicted genes, obtained using next-generation sequencing and optical mapping approaches. The sequence analysis reveals an impressive array of genes encoding cytochrome P450s (CYPs), transporters and regulatory proteins that cooperate in secondary metabolism.
