Physiological changes that drive the microalgal-bacterial consortia are poorly understood so far. In the present novel study, we initially assessed five morphologically distinct microalgae for their ability in establishing consortia in Bold's basal medium with a bacterial strain, Variovorax paradoxus IS1, all isolated from wastewaters. Tetradesmus obliquus IS2 and Coelastrella sp. IS3 were further selected for gaining insights into physiological changes, including those of metabolomes in consortia involving V. paradoxus IS1. The distinct parameters investigated were pigments (chlorophyll a, b, and carotenoids), reactive oxygen species (ROS), lipids and metabolites that are implicated in major metabolic pathways. There was a significant increase (>1.2-fold) in pigments, viz., chlorophyll a, b and carotenoids, decrease in ROS and an enhanced lipid yield (>2-fold) in consortia than in individual cultures. In addition, the differential regulation of cellular metabolites such as sugars, amino acids, organic acids and phytohormones was distinct among the two microalgal-bacterial consortia. Our results thus indicate that the selected microalgal strains, T. obliquus IS2 and Coelastrella sp. IS3, developed efficient consortia with V. paradoxus IS1 by effecting the required physiological changes, including metabolomics. Such microalgal-bacterial consortia could largely be used in wastewater treatment and for production of value-added metabolites.

Phenotypic plasticity or genetic adaptation in an organism provides phenotypic changes when exposed to the extreme environmental conditions. The resultant physiological and metabolic changes greatly enhance the organism's potential for its survival in such harsh environments. In the present novel approach, we tested the hypothesis whether acid-adapted microalgae, initially isolated from non-acidophilic environments, can survive and grow in acid-mine-drainage (AMD) samples. Two acid-adapted microalgal strains, Desmodesmus sp. MAS1 and Heterochlorella sp. MAS3, were tested individually or in combination (co-culture) for phenotypic changes during their growth in samples collected from AMD. The acid-adapted microalgae in AMD exhibited a two-fold increase in growth when compared with those grown at pH 3.5 in BBM up to 48 h and then declined. Furthermore, oxidative stress triggered several alterations such as increased cell size, granularity, and enhanced lipid accumulation in AMD-grown microalgae. Especially, the apparent limitation of phosphate in AMD inhibited the uptake of copper and iron in the cultures. Interestingly, growth of the acid-adapted microalgae in AMD downregulated amino acid metabolic pathways as a survival mechanism. This study demonstrates for the first time that acid-adapted microalgae can survive under extreme environmental conditions as exist in AMD by effecting significant phenotypic changes.

In this study, batch experiments were carried out to study the adsorption of Malachite green dye from aqueous solution by Mangifera indica (mango) seed kernel powder. The mango seed kernel powder was characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Effect of various parameters including pH, contact time, adsorbent dosage, initial dye concentration and temperature on adsorption capacity of the adsorbent was observed and the optimized condition for maximum dye removal was identified. Maximum percentage removal of 96% was achieved with an adsorption capacity of 22.8¿mg/g at pH 6 with an initial concentration of 100¿mg/l. The equilibrium data were examined to fit the Langmuir and Freundlich isotherm models. Thermodynamic parameters for the adsorption process were also calculated.

At low temperature, the presence of oleaginous compound with fatty acids bound to crystallize and cause operability problems with compression engines. In this present investigation, seven different fatty acid methyl esters (FAMEs) biodiesel from vegetable oils (such as sunflower, coconut, jatropha, rice bran, palm, neem and mahua) were prepared by transesterification and were analyzed by gas chromatography (GC). Winterization of these synthesized biodiesel were carried out to find their usability at low temperatures (0 °C¿20 °C) and the crystals formed were separated. Further, the differential scanning colorimetry (DSC) was employed to identify the onset of melting point of the biodiesel from vegetable oils. The results showed that crystal formation was observed for various biodiesel except sunflower oil that recorded no crystal formation with minimum temperature of 0 °C. These findings suggest that biodiesel synthesized from sunflower can be used as such at low temperatures compared to the other synthesized biodiesel from vegetable oil.

Bicarbonate species in the aqueous phase is the primary source for CO2 for the growth of microalgae. The potential of carbon dioxide (CO2) fixation by Chlorella pyrenoidosa in enriched bicarbonate medium was evaluated. In the present study, effects of parameters such as pH, sodium bicarbonate concentration and inoculum size were assessed for the removal of CO2 by C. pyrenoidosa under mixotrophic condition. Central composite design tool from response surface methodology was used to validate statistical methods in order to study the influence of these parameters. The obtained results reveal that the maximum removal of CO2 was attained at pH 8 with sodium bicarbonate concentration of 3.33¿g/l, and inoculum size of 30¿%. The experimental results were statistically significant with R2 value of 0.9527 and 0.960 for CO2 removal and accumulation of chlorophyll content, respectively. Among the various interactions, interactive effects between the parameters pH and inoculum size was statistically significant (P¿<¿0.05) for CO2 removal and chlorophyll accumulation. Based on the studies, the application of C. pyrenoidosa as a potential source for carbon dioxide removal at alkaline pH from bicarbonate source is highlighted.

The aim of this study was to identify the potential for cultivation of Chlorella pyrenoidosa and Scenedesmus abundans in raw and autoclaved domestic wastewater (sewage) for nutrient removal, in a batch process. The growth was observed by measuring chlorophyll content. The inoculum size of 10% and 20% was used and the growth of microalgae and nutrient removal was monitored on daily basis. The maximum removal of ammonium nitrogen, phosphate and nitrates by Chlorella pyrenoidosa in raw samples was observed as 99%, 96% and 80%, respectively, whereas the maximum removal of ammonium nitrogen, phosphate and nitrates by Scenedesmus abundans in raw samples was observed as 98%, 95% and 83%, respectively. The maximum chlorophyll content was observed as 11.33 mg/l and 7.23 mg/l for C. pyrenoidosa and S. abundans, respectively, in raw samples. The experimental results reveal that both the microalgae are capable to grow and remove the nutrients from domestic wastewater.

Over groundwater exploitation owing to population, urbanization and industrialization make the groundwater unfavorable for living beings. This study deals with the assessment of groundwater quality in Gudiyattam and Vaniyambadi blocks of Vellore district, Tamil Nadu, India where groundwater is the major source of drinking due to deficiency in surface water. The significant physicochemical parameters such as pH, conductivity, total dissolved solids, chlorides, total alkalinity, calcium hardness, magnesium hardness and sulphate were assessed. Correlation matrix, box plot, multivariate statistical tools such as cluster analysis and principal component analysis were applied to groundwater quality analysis. The groundwater samples were assessed for its applicability in irrigation and drinking purposes and geographic information system techniques are used for mapping consequence. The parameters analyzed were compared with Bureau of Indian Standards (BIS) and WHO standards. Box plot analysis revealed that total dissolved solids and electrical conductivity was strongly correlated. Correlation analysis exhibits strong correlation (R2>0.7) between total dissolved solids and electrical conductivity, anions such as Ca2+ and Mg2+ for both the study areas.

Bicarbonate source for cultivation of microalgae is an alternate method mainly to avoid CO2 loss. The main aim of the work is to assess the bio-fixation ability of CO2 from ammonium bicarbonate by Chlorella pyrenoidosa under mixotrophic condition. Furthermore, statistical optimization has been carried out to study the influence of pH, concentration and inoculum size and identify best conditions for CO2 removal. The results revealed that maximum removal of CO2 was obtained at pH 6.0; with ammonium bicarbonate concentration, 6.66 g L-1 and inoculum size, 36.81%. The obtained results were statistically analyzed and the results were obtained with regression co-efficient R2 value of 0.94 for CO2 removal and 0.86 for corresponding chlorophyll content. From the study, it can be concluded that microalgae could able to grow in ammonium bicarbonate source which indicates that microalgae could assimilate ammonium and CO2 in to their cells even at high concentration. Bicarbonate captured CO2 proves to be a significant method for cultivation of microalgae supports commercial production.

Noise levels beyond the limits are said to be noise pollution. Preventive measures are adopted by legislation by prescribing noise level, that is to be maintained at different zones in a city. In the present investigation, the noise levels in various parts of Patna city in India have been studied. Due to increase in industrial growth, population migration has constantly increasing day by day. Hence, it is important to measure noise levels as it may be major concern to know the impact of noise pollution. The noise level recorded has been compared with the Noise Pollution (Regulation and Control) Rules, 2000. The study area has been categorized in to 4 zones, such as residential zone, silent zone, commercial zone and traffic zone. The obtained results revealed that noise exceeds the permissible limit almost in all zones. The present study results are compared with the literature on noise levels in other cities in India.

A feasibility study has been conducted to determine the capability of the microalgae (Chlorella sp) to grow in sewage without sterilization in a laboratory scale batch process under the continuous illumination of light. In the present investigation, the algal growth and nutrients removal in the sewage has been studied and the experimental results revealed the growth period of microalgae as 9 days. The nutrients present in the sewage after algal growth was compared with the nutrients in the initial stage. The percentage removal of nutrients after the end of batch process is Phosphate-90.7%, Total solids -86%, Nitrates-Nitrogen-60%, Ammonia-Nitrogen-58.8%, Total dissolved solids -90%, and Total suspended solids -50%, respectively.

In this study, commercial sodium poly acrylate (SPA) is used along with sodium chloride for low salt skin preservation. SPA is a super-absorbent polymer which can absorb water many times of its own weight. The SPA used in this study was characterized using NMR, IR and its water absorption characteristics were determined. Fresh goat skins were taken for experimental and conventional preservation studies. Control skins were applied with 40% salt and kept under ambient condition. Preliminary studies were carried out on optimization of SPA contact time, quantity and amount of salt for preservation. The experimental skins were applied with 5% SPA on flesh side and kept for 4 hours for moisture removal and then, SPA was removed from the skin by gentle scrapping and taken for drying and reuse for subsequent batch of raw skins. The SPA recovery was found to be 95%. Then 15% salt was applied on experimental skins and both experimental and control skins were stored for 21 days. The skins were observed periodically for hair slip and foul smell, which are indications for onset of putrification and microbial growth as per the conventional method. After preservation period, both control and experimental skins were processed into chrome tanned leathers and tested for their strength and other properties. The results suggest that SPA aided moisture removal along with minimal salt has adequate curing efficiency similar to conventional salt preservation and has comparable physical and organoleptic properties with a substantial reduction in TDS and chlorides in effluent. This SPA aided low salt skin preservation if implemented on commercial scale pollution caused due to sodium chloride would be significantly minimized.
