The effect of culture medium on the oil yield and fatty acid methyl ester of freshwater microalgae Chlorella vulgaris

Microalgae are commonly used in the biodiesel industry to produce lipids. The selection of media is one of the vital factors to culture the microalgae. The Chlorella vulgaris used in this study as a microalgae was cultured in three different culture media, namely the Modified Bold’s Basal medium (BBM), Blue-Green medium (BG11) and Jaworski’s medium (JM) using the immobilization method. Through this method, all the cultured microalgae were cultivated for 11 days to evaluate the oil yield. Then, the extracted oil was transesterified to produce fatty acid methyl ester (FAME). It was found that the BBM medium showed the highest oil yield (71.43%), followed by JM (67.50%) and BG11 (53.14%). In addition, BBM also is the best composition to produce FAME as it contains high nitrogen.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 123-95-5. Application In Synthesis of Butyl stearate.

Comparative Profiling of Volatile Compounds in Popular South Indian Traditional and Modern Rice Varieties by Gas Chromatography-Mass Spectrometry Analysis

Rice (Oryza sativa L.) is one of the major cereal crops cultivated across the world, particularly in Southeast Asia with 95% of global production. The present study was aimed to evaluate the total phenolic content (TPC) and to profile all the volatile organic compounds (VOCs) of eight popular traditional and two modern rice varieties cultivated in South India. Thirty-one VOCs were estimated by gas chromatography-mass spectrometry (GC-MS). The identified volatile compounds in the 10 rice varieties belong to the chemical classes of fatty acids, terpenes, alkanes, alkenes, alcohols, phenols, esters, amides, and others. Interestingly, most of the identified predominant components were not identical, which indicate the latent variation among the rice varieties. Significant variations exist for fatty acids (46.9-76.2%), total terpenes (12.6-30.7%), total phenols (0.9-10.0%), total aliphatic alcohols (0.8-5.9%), total alkanes (0.5-5.1%), and total alkenes (1.0-4.9%) among the rice varieties. Of all the fatty acid compounds, palmitic acid, elaidic acid, linoleic acid, and oleic acid predominantly varied in the range of 11.1-33.7, 6.1-31.1, 6.0-28.0, and 0.7-15.1%, respectively. The modern varieties recorded the highest palmitic acid contents (28.7-33.7%) than the traditional varieties (11.1-20.6%). However, all the traditional varieties had higher linoleic acid (10.0-28.0%) than the modern varieties (6.0-8.5%). Traditional varieties had key phenolic compounds, stearic acid, butyric acid, and glycidyl oleate, which are absent in the modern varieties. The traditional varieties Seeraga samba and Kichilli samba had the highest azulene and oleic acid, respectively. All these indicate the higher variability for nutrients and aroma in traditional varieties. These varieties can be used as potential parents to improve the largely cultivated high-yielding varieties for the evolving nutritional market. The hierarchical cluster analysis showed three different clusters implying the distinctness of the traditional and modern varieties. This study provided a comprehensive volatile profile of traditional and modern rice as a staple food for energy as well as for aroma with nutrition.

Effect of Anacetrapib on Cholesterol Efflux Capacity: A Substudy of the DEFINE Trial

Background Anacetrapib is the only cholesteryl ester transfer protein inhibitor proven to reduce coronary heart disease (CHD). However, its effects on reverse cholesterol transport have not been fully elucidated. Macrophage cholesterol efflux (CEC), the initial step of reverse cholesterol transport, is inversely associated with CHD and may be affected by sex as well as haptoglobin copy number variants among patients with diabetes mellitus. We investigated the effect of anacetrapib on CEC and whether this effect is modified by sex, diabetes mellitus, and haptoglobin polymorphism. Methods and Results A total of 574 participants with CHD were included from the DEFINE (Determining the Efficacy and Tolerability of CETP Inhibition With Anacetrapib) trial. CEC was measured at baseline and 24-week follow-up using J774 macrophages, boron dipyrromethene difluoride-labeled cholesterol, and apolipoprotein B-depleted plasma. Haptoglobin copy number variant was determined using an ELISA assay. Anacetrapib increased CEC, adjusted for baseline CEC, risk factors, and changes in lipids/apolipoproteins (standard beta, 0.23; 95% CI, 0.05-0.41). This CEC-raising effect was seen only in men (P interaction=0.002); no effect modification was seen by diabetes mellitus status. Among patients with diabetes mellitus, anacetrapib increased CEC in those with the normal 1-1 haptoglobin genotype (standard beta, 0.42; 95% CI, 0.16-0.69) but not the dysfunctional 2-1/2-2 genotypes (P interaction=0.02). Conclusions Among patients with CHD, anacetrapib at a dose linked to improved CHD outcomes significantly increased CEC independent of changes in high-density lipoprotein cholesterol or other lipids, with effect modification by sex and a novel pharmacogenomic interaction by haptoglobin genotype, suggesting a putative mechanism for reduced risk requiring validation.

The current research work investigates the effect of the prodrug approach on the mefenamic acid by synthesizing the ester conjugates with natural antioxidants such as sesamol and thymol. METHODS Synthesis of two ester prod rugs, mefenamic acid-sesamol conjugate and mefenamic acid-thymol conjugate by coupling method using DCC / DMAP, subjected to physicalchemical characterization, spectral characterization (IR, H-1 NMR, C-13 NMR and Mass spectra), in-silico studies, in-vivo biodistribution studies and pharmacological evaluation such as anti-inflammatory, ulcerogenecity, activity in the brain as well as histopathological evaluation. RESULTS The ester prodrugs of mefenamic acid which upon administration would release the parent drug as a result of enzymatic or non-enzymatic hydrolysis in the desired areas with enhanced anti-inflammatory activity and reduction in the gastro intestinal toxicity. In-silico studies showed the docking score of mefenamic acid on the beta-secretase enzyme is – 7.834 and the bio-distribution study showed the enhanced distribution of the mefenamic acid in the brain. Pharmacological study and histopathology studies using the brain tissues showed the protective effect of mefenamic acid in the brain. CONCLUSIONS Antioxidant conjugates of mefenamic acid showed sustained release of the mefenamic acid and enhanced anti-inflammatory activity with reduction in the gastric toxicity. The present investigation also revealed that the enhanced transport profile across blood brain barrier and considerable protective effect in the brain against neurodegenerative conditions.

Preparation and characterization of composite quasi-solid electrolytes composed of 75Li(2)S center dot 25P(2)S(5) glass and phosphate esters

Mechanical properties and ionic conductivities of solid electrolytes are important factors influencing the performance of all-solid-state batteries. This study investigates composite quasi-solid electrolytes composed of Li2S-P2S5 glass and a phosphate ester, prepared via planetary ball milling, and the relative densities of the powder-compressed pellets, formed using the composite quasi-solid electrolytes. Dense pellets of the Li2S-P2S5 glass electrolyte are obtained via addition of phosphate esters; the relative densities increase from 90.6% to 93.1%, without the ionic conductivities decreasing, upon addition of a small quantity of tris (2, 2, 2-trifluoroethyl) phosphate to the Li3PS4 glass. The addition of small quantities of phosphate esters to sulfide solid electrolytes is effective in improving the formability of these solid electrolytes.
