Organic fraction of municipal solid waste (OFMSW) has the potential to sustain large-scale biofuel production. So far, OFMSW is mainly converted into biogas by anaerobic digestion (AD), and limited research available on its use produce bioethanol. This paper reports, for first time, conversion starch-rich bioethanol using a novel yeast co-secreting both glucoamylase alpha-amylase enzymes. As such, can be without adding costly enzymes following consolidated bioprocessing (CBP) approach. The...
The fermentation process in alcoholic beverage production converts sugars into ethanol and CO2, releasing significant amounts of greenhouse gases. Here, Cupriavidus necator DSM 545 was grown autotrophically using gas derived from fermentation, a fed-batch bottle system. Nutrient starvation applied to induce intracellular accumulation poly(3-hydroxybutyrate) (PHB), bioplastic polymer, for bioconversion CO2-rich waste PHB. Grape marc, another by-product wine production, evaluated as low-cost...
Anaerobic co-digestion of protein-rich substrates is a prominent strategy for converting valuable feedstocks into methane, but it releases ammonia, which can inhibit the overall process. This study developed cutting-edge combined culturomic and metagenomic approach to investigate microbial composition an ammonia-tolerant biogas plant. Newly-isolated microorganisms were used bioaugmentation stressed batch reactors fed with casein, maize silage their combination. A co-culture enriched...
Cupriavidus necator is a facultative chemolithoautotrophic bacterium able to convert carbon dioxide into poly-3-hydroxybutyrate. This highly promising as the conversion process allows production of sustainable and biodegradable plastics. Poly-3-hydroxybutyrate accumulation known be induced by nutrient starvation, but information regarding optimal stress conditions controlling still heterogeneous fragmentary. study presents comprehensive comparison effects conditions, namely nitrogen,...
The exploitation of agri-food wastes is great importance for environmental and economic reasons. Date are attractive biomasses that could be used as a carbon source the growth microorganisms to obtain added-value products. In this work, spoilage date syrup, containing 102.01 101.00 g/L glucose fructose, respectively, was assessed feedstock production bioethanol polyhydroxyalkanoates (PHAs) by Saccharomyces cerevisiae MEL2 Cupriavidus necator DSM 545, respectively. waste syrup first evaluated...
Abstract Background Microbial biopolymers such as poly-3-hydroxybutyrate (PHB) are emerging promising alternatives for sustainable production of biodegradable bioplastics. Their promise is heightened by the potential utilisation photosynthetic organisms, thus exploiting sunlight and carbon dioxide source energy carbon, respectively. The cyanobacterium Synechocystis sp. B12 an attractive candidate its superior ability to accumulate high amounts PHB well high-light tolerance, which makes it...
Abstract Anaerobic co-digestion of protein-rich substrates is a prominent strategy for converting valuable feedstocks into methane, but it releases ammonia, which can inhibit methanogenesis. This study developed cutting-edge combined culturomic and metagenomic approach to investigate the microbial composition an ammonia-tolerant biogas plant. Newly-isolated microorganisms were used bioaugmentation stressed batch reactors fed with casein, maize silage their combination. A co-culture enriched...
Due to their long domestication time course, many industrial Saccharomyces cerevisiae strains are adopted in numerous processes mostly for historical reasons instead of scientific and technological needs. As such, there is still significant room improvement yeast relying on biodiversity. This paper strives regenerate biodiversity with the innovative application classic genetic methods already available strains. Extensive sporulation was indeed applied three different strains, specifically...
This study utilized a circular economy approach to convert unripe rice, low-cost by-product of the rice milling industry, into biofuels using biorefinery process. The recombinant yeast Saccharomyces cerevisiae ER T12.7 strain was tested for its ability produce ethanol from rice. In hydrolysis trials with 20 % (dw/v) UR, showed superior saccharification yields comparable commercial enzyme STARGEN
