Over the past few decades, curing of diseases are under threat as many medicines and drugs produce toxic reactions. Nowadays 61% of new drugs has been developed using natural phytochemicals in curing many diseases. Present investigation is an attempt to assess the antimicrobial activity of Pergularia daemia and to evaluate the potential against antibiotics. In the present study, P.daemia proved to have efficient phytochemicals which created distinct zone of inhibition against bacterial strains.Keywords

An increase in greenhouse gas effect and depletion of fossil fuel leads to work on alternate renewable source of energy. Biofuel, in which biodiesel has gained its importance over a decade due to its promising characteristics. Crude glycerol is produced as an inevitable byproduct during biodiesel production. The carbon content of the waste glycerol can be utilized by many microorganisms as a cheap carbon and energy source for the production of high value chemicals like ethanol, citric acid, propanediol etc. In this present work simple sequential procedures like distillation, acidification, activated charcoal adsorption, filtration and centrifugation were carried out made to remove major impurities economically and increases the glycerol concentration. The removal of impurities from crude glycerol and the increase in the concentration of glycerol were witnessed from GCMS and GC-FID reports. The procedure followed in this work provided a realistic and concrete target shows a momentous proliferation of increased glycerol concentration from 10.43% to 44 %. The other properties of glycerol were studied and compared with standard methods.Keywords

Recent developments in material synthesis involve avariety of physical and chemical approaches which has substantially influenced the field of nanotechnology. These strategies play a significant role in many prospects such as synthesis of nanoparticles of variable shapes and uniform particle size distribution. Toxic chemicals in these strategies for the synthesis of metal nanoparticles create hazardous concerns for the environment. In contrary, the biological approach includes the use of bioactive components which are highly biodegradable in nature. Hence biological approach is considered as a promising method for the eco-friendly synthesis of noble metal nanoparticles.Although these noble metal nanoparticles can be synthesised in various forms such as nano-sols, nano-colloids, nano-crystallines, nanorods, nanotubes and nanowires using a variety of physical as well as chemical approaches. Besides their shape and morphology, the size of noble metal nanoparticles should be efficiently tailored to achieve the desired medical application. The increase in surface area increases the possibility of causing the aggregation of nanoparticles which limit their functionalities. The surface functionalization of noble metal nanoparticles was done using chemical dispersants such as surfactants or polyelectrolytes to avoid the aggregation.This functionalisation improves the stability of the noble metal nanoparticles but at the same time it alters the surface chemistry of the nanoparticles. It is crucial for producing the nanoparticles in such a way that they could be size controlled, inexpensive and eco- friendly. The objective of this review is, therefore, to reveal the past and present scenarios, specifically the possibilities of noble metal nanoparticles in applications. Furthermore, it also documents the detailed information about the strategies involved in the use of plant extracts as reducing agents in the synthesis of metal nanoparticles and the incorporation of metal nanoparticles into polymeric materials for environmental applications. This review paper mainly summarizes the various synthesis methods of gold and silver nanoparticles and their applications in biomedicine.Keywords

The aim of present study is to optimize the important parameters of total phenol extraction form Azadirachta indica wood using ethanol. Experiments were conducted based on the central composite rotatable design (CCRD) and the models were constructed using response surface methodology (RSM). Response Surface Methodology (RSM) was employed for optimization of influencing factors such quantity of wood, temperature and extraction time in total phenol extraction using ethanol as solvent. The levels of mentioned parameters were in the range 1-5% of quantity of wood, 20-60°C of temperature and 1-5 days of extraction time were evaluated. The optimization of individual parameters were determined the 5% for quantity of wood, 50°C for temperature and 4 days for incubation time as central values. Based on the central values, 17 experiments were designed and experimentally conducted. The responses of 17 experiments were used for optimization. The best optimal condition of total phenol extraction was determined as quantity of wood 4.55 %, temperature 59.24°C and extraction time 3.92 days with extraction yield 0.958 mg Gallic acid equivalents (GAE)/g of dry powder. The phenolic extract quality was evaluated using thin layer chromatography and GC-MS analysis. The extract shows good anti-bacterial activity against E. coli and S. aureus.Keywords

The clean production concept shows a good utilization potential for solid vegetable waste. It could achieve a reduction of investment and raw materials and can contribute to waste minimised plant production. Thus rendering cheap and environmentally safe alternative to commercial media. At present study was aimed at finding the potential of vegetable waste as a culture media. Composition of the media and the efficiency of the media to support plant growth were tested. Vegetable waste of Cabbage, Beetischolar_main and Onion were collected and dried in the sun light for 2 weeks. Dried vegetable waste was grinded into fine powder. These vegetable waste media (alternative plant tissue culture media) was prepared and coconut water was added for natural hormone (cytokinin). The alternative media pH was 5.6 to 5.7 before sterilization. The vegetable waste powder was analysed for Macronutrients which include potassium (268 mg/kg), sodium (520 mg/kg), calcium (1591 mg/kg), while the micronutrients were analysed copper (5.421 mg/kg), iron (1101 mg/kg) and zinc. The growth was comparable to that obtained on routine commercial media.Keywords

We have developed simple and efficient regeneration protocol using plant growth regulators and naturally available seaweed. Efficiency of Sargassum polycystum in promoting the growth of Vigna unguiculata at in vitro condition were studied. Equal sized seeds were inoculated in different concentration of seaweeds, we found that 20% of extract shown 100% germination compared to control. Initially, TDZ and Kin were tested for the multiple shoot induction. Best responded concentration was tested in combination with the seaweed extract Sargassum polycystum. We observed increase in the multiple shoot induction from 10.2 shoots per explant to 14.8 shoots per explant. Seaweed extract induced shoot elongation and ischolar_maining at in vitro condition. So we believe that, seaweed extracts has biostimulant activity, the activity of the seaweed extract is due to presence of more than one plant promoting substances.Keywords
