TL;DR: In this article, a Candida rugosa lipase (CRL) was immobilized on the octyl-functionalized ordered mesoporous silica (C8-OMMs) to obtain immobilized CRL arrays.
Abstract: Rice bran oil (RBO) is a great and important vegetable oil resource, but usually contain high content of free fatty acids (FFAs). Phytosterol esters are functional lipids possessing hypocholesterolemic activity. In this study, Candida rugosa lipase (CRL) was immobilized on the octyl-functionalized ordered mesoporous silica (C8-OMMs) to obtain immobilized CRL arrays (CRL@C8-OMMs). The resulting CRL@C8-OMMs arrays showed much better thermal stability and reusability in comparison to free CRL. The deacidification and simultaneous preparation of functional oil rich in phytosterol esters (PEs) was successfully achieved by enzymatic esterification of high-acid RBO with phytosterol. The contents of FFAs and PEs were below 2.3% and above 84.7%, respectively. Repeated reaction tests indicated that CRL@C8-OMSs arrays could be used 11 times with 80.7% of its original catalytic activity still retained. The strategy could not only take advantage of the high-acid oils resources, but also product PEs-enriched functional oils.

TL;DR: In this article, an unknown ferulate in rice bran oil was isolated by column chromatography and the ferulate was identified as methyl ferulate by TLC, GLC, UV, IR, NMR and mass spectrometry.

TL;DR: Results from the present study could be scientific evidence to demonstrate that oil-pulling therapy with some edible oils could probably be used as a preventive home therapy to maintain oral hygiene against dental caries especially in developing countries.
Abstract: Objective: To investigate the effect of oil-pulling against oral microorganisms in biofilm models. Materials and Methods: The effect of oil-pulling using coconut oil, corn oil, rice bran oil, palm oil, sesame oil, sunflower oil and soy bean oil was evaluated on biofilm models formed by Streptococcus mutans KPSK2, Lactobacillus casei ATCC 6363 and Candida albicans ATCC 13803 on salivary-coated microtiter plates. Saline solution and 0.2% chlorhexidine gluconate solution were used as negative and positive controls, respectively. Results: It was found that coconut oil exhibited antimicrobial activity against S. mutans and C. albicans. Sesame oil had antibacterial activity against S. mutans whereas sunflower oil had antifungal activity against C. albicans. However, L. casei was found to be resistant to all tested oils. Conclusion: Results from the present study could be scientific evidence to demonstrate that oil-pulling therapy with some edible oils could probably be used as a preventive home therapy to maintain oral hygiene against dental caries especially in developing countries.
