The simultaneous saccharification and fermentation of malt dust and use in the acidification of mash
Baltaci, Saadet Fatma; Hamamcı, Haluk (2019-01-01)
In brewing, the mash or wort is frequently acidified by the addition of lactic acid or the bioacidification of the mash. The present study provides an alternative approach for mash or wort acidification by the simultaneous saccharification and fermentation (SSF) of malt dust. In this method, fermentable carbohydrates released by the enzymatic breakdown of the cellulosic portion of the malt dust are converted to lactic acid by lactic acid bacteria. The effect of temperature, ranging between 45 and 51 degrees...
An ozone assisted process for treatment of EDC's in biological sludge
Muz, M.; Ak, M. S.; Komesli, O. T.; Gökçay, Celal Ferdi (2013-02-01)
A novel aerobic sludge digestion process to stabilize and decrease the amount of excess sludge produced during biological treatment and removal of EDCs sorbed onto sludge during this process is discussed here. Waste activated sludge samples from two different wastewater treatment plants were ozonated for different periods in Erlenmeyer flasks once a day on each of four consecutive days. Flasks were continuously aerated between ozone applications by shaking on an orbital shaker. The residual EDC concentratio...
The removal of colour, carotene and acidity from crude olive oil by using sepiolite
Ugurlu, Mehmet; Kula, Ibrahim (Wiley, 2007-03-01)
The capacity of sepiolite to adsorb colouring matters in olive oil was studied. The effects of adsorption time, temperature and solid:liquid ratio were selected as parameters. The effect of bleaching of olive oil was evaluated for determining the % free fatty acid (FFA), % bleachability and residual carotene by using both thermally activated sepiolite (AS) and acid-activated sepiolite (AAS). Results reveal that thermally acid-activated sepiolite was more efficient than thermally activated sepiolite. The ads...
Two-phase anaerobic digestion of unscreened dairy manure
Demirer, Göksel Niyazi; Chen, S (Elsevier BV, 2005-11-01)
Concentrated animal feeding operations along with a corresponding absence of suitable manure disposal methods have been shown to cause significant environmental and public health problems, including odors and nutrient enrichment and pathogen contamination of surface and ground waters. Anaerobic digestion (AD) of manure can offer substantial benefits, both economic and intangible, to animal feeding operators and surrounding communities, such as on-site energy generation, production of stable, liquid fertiliz...
An LCMSMS method to analyse phenolic profile in the liquid extract, with woodland strawberry (Fragaria vesca l.) application
Şeker, Tamay; TÜRKER, ARZU; Yucel, Meral (2012-09-23)
The most of the bioactive compounds are found in trace amounts so, an efficient extraction procedure from a given tissue is a big problem. An efficient quantitative detection coupled to the extraction procedure is necessary in order to cover the whole phenomena. The increasing dissolution volume of the lyophilized sample may result in dilution of the total content of the phenolics. In choosing the analytical measurement method, the lower sample-enjection volume, the seperate detection of the phenolics havin...
