Present investigation studied the potential of fresh water green microalga Scenedesmus abundans as a feedstock for biodiesel production. To study the biomass and lipid yield, the culture was grown in BBM, Modified CHU-13 and BG-11 medium. Among the tested nitrogen concentration using Modified CHU-13 medium, the highest biomass and lipid yield of 1.113±0.05g/L and 489±23mg/L respectively was found in the culture medium with 0.32g/L of nitrogen (KNO3). Different lipid extraction as well as transesterification methods were also tested. Fatty acid profile of alga grown in large scale indigenous made photobioreactor has shown abundance of fatty acids with carbon chain length of C16 and C18. Various biodiesel properties such as cetane number, iodine value and saponification value were found to be in accordance with Brazilian National Petroleum Agency (ANP255) and European biodiesel standard EN14214 which makes S. abundans as a potential feedstock for biodiesel production. © 2014 Elsevier Ltd.

Objective: Present communication deals with the study of antihepatotoxic activity and molecular prediction of compounds isolated from Phyllanthus debelis in order to search lead compound. Methods: Five compounds from the whole plant of P. debelis were subjected to molecular properties prediction and drug-likeness by Lipinski rule of five & Molinspiration software. Results: All the compounds were found in compliance with Lipinski 'Rule of Five' except the Milog P valve of compound No. I-IV were found above five means these compounds have less permeability across the cell membrane. The Milog P valve of Compound No V & standard compound silibinin VI were found below five, suggest that the molecules have good permeability across the cell membrane. In respect of TPSA, all the compounds were within the limit i.e. 160 å. The bioactivity score was also calculated for GPCR ligand, ion channel modulator, kinase inhibitor, nuclear receptor ligand. All the compound showed activity through enzyme inhibition. Conclusions: Our study shows that compound V debelolactone has good drug likeness score with no violations & good bioactivity score as compared to silibinin which is potent hepatoprotective drug. So compound V debelolactone can be a lead compound with hepatoprotective activity from Phyllanthus debelis. © 2012 Asian Pacific Tropical Biomedical Magazine.

SWAP (Soil-Water-Atmosphere-Plant) version 2.0 was evaluated for its capability to simulate crop growth and salinity profiles under various combinations of fresh and saline water use for irrigation at Agra (India), located in a semiarid monsoon climatic region having a deep water table. Best available water (BAW, EC 3.6. dS/m) was used for pre-sowing irrigation to wheat crop and thereafter, twelve treatment combinations were imposed with four replications to supplement missed BAW water irrigations with saline water (EC 6/8 and 12. dS/m). The model was calibrated and validated using measurements made in field trial during 2000-2003. A close agreement was observed between the measured data and simulated values. SWAP simulated and observed values for the relative yield ranged within absolute deviations of 4.2-9.7%. The validated model was later used to illustrate the consequences of long-term use of saline water on crop growth and salinity profiles. Simulated results confirmed that a yield potential exceeding 80% could be maintained by substituting saline waters up to 8. dS/m in the absence of fresh water following a pre-sowing irrigation with BAW. This strategy helps to overcome the build-up of salts particularly in years when the monsoon rainfall is below average. It could be shown and concluded that seasonal build-up of salts due to use of saline water in winter season (November-April) crops is leached during the monsoon season (June-September) when rainfall at least during the months of July and August exceeds the potential evapotranspiration. On the whole, short-term field observations could be confirmed with application of SWAP that long-term use of saline water in monsoon climate under deep water table conditions is sustainable. © 2012 Elsevier B.V.

Yoghurt is a snow white, custard like fermented milk product, obtained through the controlled lactic acid fermentation of milk by Lactobacillus bulgaricus and Streptococcus thermophiles. A study was undertaken by using different levels of Goat milk and Apple pulp i.e. T1 (90:10), T2 (85:15), T3 (80:20) respectively. Experimental fruit yoghurt mix was standardized to 4.0% fat, 11.5% solids not fat, 10% sugar and 2% culture adjusted to 25.2% total solids. Yoghurt samples for different treatments were analyzed for organoleptic attributes (colour and appearance, body and texture, taste and flavour) by trained panelist using 9 point hedonic scale. The fruit yoghurt obtained from (80:20) (T3) ratio was the best product among all treatments. Thus, as far as product acceptability judged by organoleptic evaluation, the treatment can be rated as T3 > T0 > T2 > T1.

Objective: To assess in vitro antioxidant activity of the essential oil isolated from fresh rhizomes of garlic (Allium sativum) of the family Alliaceae in an yield of 0.2% (v/w). Methods: 2, 2-diphenyl-1-picrylhydrazyl (DPPH), Nitrogen oxide scavenging, reducing power and β -carotene bleaching assays were conducted. BHT and gallic acid were kept as standards. Results: IC 50 values observed for DPPH and nitric oxide scavenging assays were 0.5 mg/mL and 50 μ g/mL respectively. In reducing power assay absorbance increased linearly with increasing concentration of the oil, in β -carotene bleaching method also there is 84% bleaching in first one hour and it decreased to 45 % by the completion of second hour. Conclusions: The results clearly indicate garlic essential oil is effective in scavenging free radical and has the potential to be powerful antioxidant.

Objective: Present research communication was towards the investigation of antifungal minimum inhibitory concentration (MIC) and minimum fingicidal concentration (MFC) activity of some substituted clubbed thiazole-1,3,5-triazines derivatives and effect of physicochemical properties on bioactivity. Material and methods: MIC and MFC were evaluated against . Candida albicans, . Candida glabrata, . Cryptococcus neoformans and . Aspergillus niger using modified microdilution method recommended by CLSI. Cytotoxicity was determinate on the viability of marine shrimp larvaes. SAR and physicochemical correlations were studied by Molinspiration software. Results: The . 5 and . 9 derivatives showed an excellent antifungal activity with MIC lower than fluconazole and equivalent to amphotericin B specially against . C. . albicans and . C. . glabrata. The toxicity of these two derivatives was non-existent for . 5 and moderate for . 9 at the used concentration. SAR study around prototype molecule suggests that presence of di-hydrophobic fragment on 1,3,5-triazine is necessary for antifungal activity than halogen substituted aromatic amine. Conclusion: On the basis of selectivity, potency and non-toxicity, we have obtained two molecules (5 and 9) as prospective leads for further research work on 1,3,5-triazine as antifungal drug. © 2011 Elsevier Masson SAS.

With the current upward trend in national and international health awareness among the consumers, the demand for herbal food has increase. A study was conducted to develop an ice-cream by partial addition of ginger juice and to evaluate its effect on, Physicochemical and microbial quality of the product. For control, Ice-cream mix was standardized to 10% milk fat, 15% sugar, cream, SMP and 0.5% stabilizer and emulsifier to obtain 37.5% total solids and treatment (T1) was standardized to 10% fat, 2% ginger juice, 0.3% stabilizer and 0.2% emulsifier. (T2) was standardized to 10% fat, 15% sugar, 0.3% stabilizer, 0.2% emulsifier, 4% ginger juice. (T3) was standardized to 10% fat, 0.3% stabilizer, 0.2% emulsifier and 6% ginger juice. The ice-cream samples of different treatments are analyzed for physicochemical (fat, total solids, acidity, protein, moisture, ash). Microbiological analysis was carried out to assess the shelf life by SPC and coliform tests. The treatments containing 6% level of ginger juice score the highest value. Thus, as far as product acceptability judged by physicochemical properties, the treatment can be rated as T3> T2> T0> T1. On the basis of result obtained it can be concluded that the ginger can be successfully used for the preparation of herbal ice-cream, without sacrificing its palatability and therapeutic values.
