Researchers to develop prebiotics from nonedible forest and sea resources

first_imgReviewed by Alina Shrourou, B.Sc. (Editor)Apr 24 2019With the help of forest residues such as sawdust, branches and tops (GROT) and cellulose from sea squirts, researchers in Biochemical Process Engineering at Luleå University of Technology, want to make our stomach to feel better. The researchers are the first to develop prebiotics from non-edible forest and sea resources, into a type of fiber that helps beneficial bacteria in the large intestine to thrive and multiply.We want to investigate whether we can obtain food products with prebiotic properties for animals and humans using cellulose from residues of forest and sea, Ulrika Rova, says, professor of Biochemical Engineering at Luleå University of Technology and project manager.Branches and tops become useful dietary fiberIt is through forest residues and by utilizing the outer cellulosic outer layer of sea squirt, the tunic, that the researchers, using mild chemical processes and enzymes, will produce useful dietary fiber, celloligosaccharides (COS), with prebiotic properties that promote health promotion for the gastrointestinal flora. Prebiotics are fibers that pass untouched through the digestive system and begin to be digested first in the colon by intestinal bacteria.- Sveaskog works broadly to develop new applications for our biomass. To be able to contribute to improved health in both people and animals with our GROT is good, Ann-Britt Edfast, says, R&D manager at Sveaskog.The researchers at Luleå University of Technology are the first to develop prebiotics from cellulose of forest and sea residues, a way to increase the value of resources from forest and sea. The forest residues, from Sveaskog, arrive to the scientists as sawdust in bags to the lab, where it is grounded to fine powder in a food mill. The researchers then isolate the cellulose using the research team’s own developed organosolv reactor. There, the researchers produce a cellulose that contains very little lignin, which is an advantage in the actual production of prebiotic (celloligosaccharides). The method is also used to produce cellulose free from proteins, lipids and ash substances from the sea squirt tunic that is provided by Marin Biogas.Related StoriesResearchers invent graphene-based biosensor to detect stomach-cancer causing bacteriaScientists discover how resistance to the chemotherapy drug 5-fluorouracil arisesStudy uncovers origin of cell mask that hides stomach cancerFor the benefit of animals and humansThe biggest challenge for the research team is then to add the right mixture of enzymes (commercial and in-house produced) to the cellulose so that one gets a desired prebiotic product consisting of 2-6 glucose units. The researchers’ goal is for their marine and forest-produced prebiotics to establish a commercial production of prebiotics for the food and feed industry – for the benefit of animals and humans.- Essum in Umeå, whose CEO Eva Grahn Håkansson, known for, among other things, having developed Verum hälsofil (processed sour milk) will then evaluate our prebiotic’s health-promoting properties and whether it can be used for human consumption. The Swedish University of Agricultural Sciences (SLU) will test whether the prebiotic can be used to strengthen the immune system and the growth of farmed fish and thereby reduce the antibiotic consumption in fish farms, Ulrika Rova, says.The research project Food-grade prebiotic production, merging marine and forest resources for moving up the cellulose value-chain, led by Luleå University of Technology, is done in close collaboration with Essum AB, Marin Biogas AB, which cultivate sea squirt for the production of environmentally friendly fish feed, Sveaskog AB, Dyrka AB and LTU Business. The project is funded by Vinnova, the Swedish Energy Agency and Formas via the strategic innovation program BioInnovation.Source: https://www.ltu.se/?l=enlast_img read more

Facebook faces a day of reckoning at least on Wall Street

first_imgThere’s a scratch in Facebook’s Teflon coating. Facebook hammered as user growth cools © 2018 The Associated Press. All rights reserved. In this March 29, 2018, file photo, the logo for Facebook appears on screens at the Nasdaq MarketSite in New York’s Times Square. Facebook’s user base and revenue grew more slowly than expected in the second quarter of 2018 as the company grappled with privacy issues, sending its stock tumbling after hours. (AP Photo/Richard Drew, File) The social network’s user base and revenue grew more slowly than expected in the second quarter as the company grappled with privacy issues, sending its stock tumbling after hours.The company also warned that it expects revenue growth to decelerate in the next couple of quarters as it promotes new, and for now less profitable, products— such as its Stories disappearing message feature. It is also allowing users to make “more choices” around data privacy amid public outcry and regulatory pressures.The earnings covered the company’s first full quarter since the Cambridge Analytica privacy scandal erupted. But analysts attributed the user growth shortfall largely to European privacy rules that went into effect in May, not to the furor over the political consulting firm with ties to President Donald Trump, which improperly accessed the data of tens millions of Facebook users.With an hour before trading began Thursday, shares had plunged more than 19 percent, plucking about $17 billion in net worth out of the pocket of Facebook founder Mark Zuckerberg.Still, the results suggest that Facebook may have weathered the scandal without major harm to its business, even if its public image has taken a hit. While revenue fell short of Wall Street estimates, it did so by only about 1 percent; profits, meanwhile exceeded forecasts.But Facebook continues to grapple with big existential questions, ranging from its users’ privacy to tech addiction to how it deals with fake news and misinformation, hate speech and extremism on its service.At times, it has seemed as though Facebook can’t quite decide where its values really lie. For instance, it continues to straddle the line between policing what users say and remaining a neutral platform in an increasingly divided world, and between protecting privacy while collecting as much information on its users as possible.Facebook had 2.23 billion monthly users as of June 30, up 11 percent from a year earlier. Analysts were expecting 2.25 billion, according to FactSet. User growth—both on a monthly and daily basis—was flat in the U.S. and the rest of North America, while it declined slightly in Europe.Facebook has largely saturated in the U.S. and Western European markets, and is now looking to countries such as Brazil, India and Indonesia for new users. Revenue from these regions, however, is far below what Facebook rakes in from the U.S. and Europe.The company earned $5.1 billion, or $1.74 per share, up 31 percent and above analysts’ estimates of $1.71.But revenue—up 42 percent to $13.23 billion— was slightly below the $13.34 that Wall Street was expecting.Facebook said the European privacy rules, called General Data Protection Regulation, or GDPR, did not have a big effect on the quarter’s revenue, but also noted that they were only in effect for about a month before the quarter ended.Over the long term, GDPR may end up favoring Facebook and other large companies that have the resources to adapt to new requirements. They could similarly disadvantage smaller, lesser known companies that don’t have the resources to comply and which could face big fines if they don’t.One bright spot for Facebook has been Instagram, the photo-sharing app it bought for $1 billion in 2012. Instagram now has more than 1 billion users, and analysts expect it to be a model for how Facebook molds its other big app purchase, WhatsApp, into a lucrative business. So far, WhatsApp doesn’t show ads, and its founders Jan Koum and Brian Acton left Facebook amid disagreements over advertising and other issues.center_img This document is subject to copyright.

Chennai  The train was supposed to reach Chennai on July 11, but leakages in the valves led to the delay. Jolarpettai is 217 km away from the southern metropolis.All the arrangements took around 20 days of time to complete.The initiative would be formally inaugurated by Tamil Nadu Ministers later in the day, the official said. A train carrying 2.5 million litres of water arrived in Chennai, which has been grappling with an acute water crisis over the past few months, officials said on July 12.The train with 50 tank wagons (BTPN), carrying 50,000 litres of water in each of them from Jolarpettai in Tamil Nadu’s Vellore district, reached the filling station at the Integral Coach Factory Yard in Villivakkam on the afternoon of July 12.Around 100 inlet pipes installed near the railway tracks would be used to discharge 2.5 million litres of water in all the wagons to be sent to a treatment plant after passing through a conduit, an official of Chennai Metropolitan Water Supply and Sewerage Board said.“After treatment it would be sent for distribution. This arrangement has been made for the next six months until the (advent of the) north-east monsoon,” the official told PTI.Play VideoPlayUnmuteCurrent Time 0:00/Duration Time 0:00Loaded: 0%Progress: 0%Stream TypeLIVERemaining Time -0:00 Playback Rate1ChaptersChaptersdescriptions off, selectedDescriptionssubtitles off, selectedSubtitlescaptions settings, opens captions settings dialogcaptions off, selectedCaptionsAudio TrackFullscreenThis is a modal window.The media could not be loaded, either because the server or network failed or because the format is not supported.Caption Settings DialogBeginning of dialog window.
