Ethanol production by using edible feedstocks like sugarcane and grains became a point of concern in terms of the food supply and demand. (imedpub.com)
But because of disputation of food versus energy, ethanol production from lignocellulosic residues has earned noticeable attention as a wide variety of feedstocks can be used as materials with no significant competition with the food chain [ 5 - 7 ]. (imedpub.com)
The cellulase showing cells could also be recycled between lignocellulose digestions, further demonstrating their practicality.41 Most recently, MGC7807 improved ethanol production. (insulin-receptor.info)

A high yielding and end product resistant mutant UNSC-442 was finally selected having substantially higher cellulase production abilities. (iitr.ac.in)

The activity of CM-cellulase and xylanases for the non-mixed system increased to about 22.0 IU/g and that of FP-ase stayed on the level of about 4 IU/g dry matter, whereas for the mixed system the CM-cellulase activity increased to about 35 IU/g dry matter on day five and that of FP-ase stayed on a similar level of about 5 IU/g dry matter. (olsztyn.pl)
In paper industry, xylanases are used to increase the pulp properties in bleaching process as its eco-friendly nature. (nih.gov)

In contrast, xylanase activity was increased 6-fold. (biomedcentral.com)
They also developed a metric to show that combinations of cellulases designed to bind to cellulose structural organizations that are similar but not identical can generate valuable synergistic activity. (canadianbiomassmagazine.ca)
The immobilized cellulase activity can still retain 74.8% after 5 cycles. (woodrefinery.com)
Later on, the investigators improved activity by adding a third enzyme and several cellulose binding modules (CBM).38,39 These cells are capable of fermenting amorphous phosphoric acid swollen cellulose (PASC) into ethanol, which is a better lignocellulose mimic than soluble cellodextrins. (insulin-receptor.info)

This pressurized treatment can be repeated at altered temperatures and pressures in different zones increasing each subsequent time, therefore, labeled as a counter-current process. (wikipedia.org)
Advanced biotechnology can reduce stem length to make the trunk shorter and thicker, reduce the number of branches and leaves, increase growth rate, improve adaptation to hostile climates, reduce negative response to competition, increase carbon sequestration, and improve the partitioning of biomass into components more favorable for subsequent conversion. (the-scientist.com)

Plants convert sunlight to biomass, which is primarily composed of lignocellulose, the most abundant natural biopolymer and a potential feedstock for fuel and chemical production. (nature.com)

In addition to bioethanol production, the major industrial application of cellulases is in the textile industry for bio-polishing and in the production of detergents for fabric softness and brightness [ 3 ]. (arocjournal.com)
Lignocellulosic biomass comprises non-edible feedstock opened a new method for the second-generation bioethanol production. (imedpub.com)

Although transportation and the burning of fossil fuels have typically been regarded as the chief contributors to GHG emissions and climate change, a 2006 report, Livestock's Long Shadow: Environmental Issues and Options [ Food and Agriculture Organization of the United Nations (FAO) 2006 ], highlighted the substantial role of the farm animal production sector. (nih.gov)

11. Simplifying cellulase production by using environmental selection pressures and recycling substrate. (nih.gov)

Increasing temperature and decreasing precipitation has led to more frequent and extreme drought events in many regions throughout the world. (researchgate.net)
Since the mid-1970s, however, the rate of increase in temperature rises has tripled. (nih.gov)
Although some natural occurrences contribute to GHG emissions ( IPCC 2007c ), the overwhelming consensus among the world's most reputable climate scientists is that human activities are responsible for most of this increase in temperature ( IPCC 2007a ). (nih.gov)

17. An ascomycota coculture in batch bioreactor is better than polycultures for cellulase production. (nih.gov)

The present review highlights the production technology, microbiology, nutritional composition, and therapeutic potential of natto. (researchgate.net)
This can improve the nutritional value of feed, reduce feed costs, and reduce the environmental impact of poultry farming by decreasing the amount of undigested feed that ends up in manure. (thepoultrypunch.com)
With cellulase, the nutritional value of feed is increased, and the amount of undigested feed in manure is decreased. (thepoultrypunch.com)

Elsam, a Danish power company, began looking at using biomass for the production of energy in the 1990s. (wikipedia.org)

Improved feed efficiency, weight gain, and productivity of your flock. (thepoultrypunch.com)
Biological pretreatment + Mg-Zn Fe 2 O 4 NPs using coculture significantly stimulated hydrogen yield (3254 mLH 2 /L), hydrogen efficiency)216.9 mL H 2 /g reducing sugar( and hydrogen production rate (67.7 mL/L/h) to the maximum among all pretreatments. (biomedcentral.com)

Others claim that CBD oil can decrease seizures, improve sleep, and reduce anxiety. (vitanetonline.com)

Lastly, we found that monitoring changes in cell wall glycan compositions and their relative extractability for untreated and pre-treated plant biomass can provide an improved understanding of variations in structure and composition of plant cell walls and delineate the role(s) of matrix polysaccharides in cell wall recalcitrance. (osti.gov)

Genetic polymorphisms in the vitamin D receptor (VDR) may influence the biological effects of vitamin D and increase a person's susceptibility to cancer. (bvsalud.org)

In poultry, probiotics are used to promote a healthy gut microbiota, which can improve digestion and nutrient absorption, boost the immune system, and help protect against harmful pathogens. (thepoultrypunch.com)
