    Stability of Orange Oil-in-Water Emulsions Prepared by Multilayer Membranes 

    Suwimon Ariyaprakai; Qi, Wu Jai (2013)

    Due to the small molecular size of orange oil, primary orange oil–in-water emulsion can easily undergo Ostwald ripening destabilization. To improve the stability of orange oil emulsion, multilayer emul- sion was prepared using Citrem as emulsifier and gelatin as coated biopolymer. Firstly, primary emulsion containing 20 wt% orange oil and 0.4 wt% Citrem was produced. Since Citrem was an anionic emulsifier, the primary emulsion had a negative charge of ~ -57mV. Then, the primary emulsion was suspended in 0.5 wt% gelatin aqueous solution ...

    Use of Rice Hull Hydrolyzate in the Cultivation of Lactobacillus acidophilus 

    Tatsaporn T.; Nikapong Puanglamyai (2012)

    This project aims to minimize the cost of production of live L. acidophilus by replacing the expensive carbon source in the fermentation medium with the rice hull hydrolyzate and compare the growth efficiency of the microbe in the rice hull formulated medium with the rich medium (de Man Rogosa Sharpe or MRS). Rice hull was hydrolyzed with diluted H2 SO4 and HCl at various concentrations 0.25, 0.5 and 1% v/v at 120 o C for 30 minutes. The hydrolyzate was further overliming with Ca(OH) 2 and filter through the diatomaceous earth. ...

    Zymomonas mobilis biofilm formation on different types of carriers 

    Tatsaporn Todhanakasem; Rashmi Tiwari (2016)

    Zymomonas mobilis biofilm have been proposed to enhance the bioethanol production from agricultural derived materials. Z. mobilis biofilm reactor has been prospected to be used for a large scale bioethanol production. The cost effective carrier for Z. mobilis biofilm reactor was searched. This study investigated the biofilm forming abilities of Z. mobilisstrain TISTR 551 and ZM4 on biotic (loofah and corn silk) or abiotic carriers (flatted sheet polyvinyl chloride, PVC). Biofilm formation was visualized for 3 consecutive days under the bright-field ...
