The present investigation is focused on the removal of Ni(II) ions from aqueous environment using gum (GA) based and clay (MMT) based nanobiocomposite beads composed of CuO NPs and chitosan (Ch). The potential of beads was exploited in terms of pH (2.0-10.0), contact time (2-36 h), temperature (10-50 °C), initial metal concentration (100-1200 mg L-1) and adsorbent dosage (1.0-6.0 g L-1) during the adsorption process. Under optimized condition, maximum Ni(II) removal (95.05%) was exhibited by clay based nanobiocomposite (CuO-Ch-MMT) beads followed by gum based nanobiocomposite (CuO-Ch-GA) beads (90.12%). Equilibrium data showed the best fit to Langmuir model with the highest adsorption capacity suggesting a homogeneous mode of Ni(II) adsorption onto the nanobiocomposite beads. Kinetic studies showed better applicability of pseudo-first order model suggesting physisorption as the underlying phenomena. Thermodynamic studies showed that the process was endothermic and spontaneous. The adsorption mechanism of CuO-Ch-GA and CuO-Ch-MMT beads was further elucidated using SEM, EDX and FT-IR analyses. Ex-situ studies showed a maximum Ni(II) removal of 88.26% from electroplating wastewater using CuO-Ch-MMT beads in column mode. Regeneration studies suggested that CuO-Ch-MMT beads could be consistently reused up to 4 cycles.Keywords

The present investigation is focused on the application of bimetallic zinc-silver (Zn-Ag) nanoparticles embedded in montmorillonite (MMT)-polysaccharide (chitosan-Ch and gum ghatti-Gg) nanobiocomposites for the removal of dichlorvos (DCV) from aqueous solution. Operating parameters viz., pH (4.0-11.0), contact time (30-360 min), temperature (20-50°C), initial DCV concentration (20-140 mg/L), composite dosage (0.2-1.2 g/L) were optimized. Zn-Ag/MMT/Ch nanobiocomposite showed the maximum removal of DCV (96.6 %) followed by Zn-Ag/MMT/Gg (85.3 %) nanobiocomposite and Zn-Ag/MMT (64.3 %) nanocomposite. The process followed a heterogenous mode of DCV adsorption by all the composites. The kinetic studies indicated that the DCV adsorption followed pseudo-first order model. Intraparticle diffusion and Boyd plot suggested that the film diffusion was not the sole rate limiting step. The thermodynamic parameters indicated the feasibility and exothermic nature of DCV adsorption. The mechanism of adsorption process was further elucidated by FT-IR, AFM and EDX analysis. Packed bed column studies showed the removal of DCV up to 79.3 % using Zn- Ag/MMT/Ch under 12 cm bed height, 1 ml/min of flow rate and at 0 % dilution. Regeneration studies suggested that the Zn-Ag/MMT/Ch could be reused up to three cycles.Keywords

In the present study, ten yeasts were isolated from fruit juices and subjected to in vitro tests for screening probiotic potentiality. Three isolates exhibited higher tolerance for pH and heat stress. Based on preliminary screening, isolates were subjected to molecular identification and identified as Wickerhamomyces anomalusVITASN01, Saccharomyces cerevisiae VIT- ASN03 and Yarrowia lipolytica VIT- ASN04. The screened yeast isolates survived and grew well at human gastrointestinal conditions in pH 2.5 and 0.3% (w/v) oxgall at 37°C. The antagonistic activity of yeast isolates were tested against clinical pathogens, viz.S. typhii, B. subtilis and E. coli. W. anomalusVIT-ASN01 showed maximum tolerance to high bile salt concentration and acidity, could remove cholesterol 51.28% during 48 h and produced 586.55 mg/L of exopolysaccharide. It can be concluded that the screened novel yeast isolates can serve as promising probiotics in various fields of food industry.Keywords

The present study investigates the role of yeasts, isolated from different environments for its abilities to synthesize biodegradable polymer, Polyhydroxyalkanoates (PHA) and its copolymers. Serial dilution method and spread plate technique had been used for the isolation of yeasts from different samples. Screening had been done by crotonic assay followed by UV Spectrophotometric analysis. Growth parameters such as effect of carbon sources, incubation period, inoculum percentage, incubation temperature and pH of the production medium were optimized for each of the screened isolates. Characterization of PHA was done by FTIR and GCMS analysis. Maximum PHA produced was observed after 96 hours of incubation period inoculated with 2% (v/v) of inoculum in minimal media of pH 8 containing various carbon sources viz. 5% sucrose for Isolate1; 5% glucose for Isolate 2; 3% starch for Isolate 3 and 5% Lactose for Isolate 4. Incubation temperature was maintained at 37°C. Maximum PHA production was noted as 40 % in Isolate 1, 33% in Isolate 2, 29% in Isolate 3and 25% in Isolate 4 respectively on the basis of dry cell weight under optimized condition. Prominent peaks obtained through FTIR analysis at wavelength 3273, 2922, 1739 and 1462 cm -1 showed the presence of stretching bands of -OH-,-CH-, -C=O- and -CH3- group which are the characteristic peaks of PHA polymer. GC-MS chromatogram detected the peaks at retention time 3.063 and 19.25 min were corresponding to the derivatized products of butanoic acid (polyhydroxybutyrate) and octadecanoic acid (polyhydroxyoctadecanoate).The present study demonstrated that yeast Isolate 1 could produce high amount of PHA (40% on dry cell weight basis ) with hydroxybutyrate (HB) and hydroxyoctadecanoate (HOD) as its main constituents.Keywords

The present study had investigated the role of yeasts, isolated from soil and food samples for its ability to synthesize silver nanoparticles. Serial dilution method followed by spread plate technique was used for isolation of yeasts on YEPD agar medium and the morphological characterization was done by simple staining technique. Primary screening was done by visual colour change followed by UV spectrophotometric analysis. Significant color change and prominent peaks around 420-450 nm were noted through UV spectrophotometric analysis in the cell free extract of Isolate 5, Isolate 8 and Isolate 13, revealed the synthesis of Ag-NPs. Optimization of growth parameters for the enhancement of Ag-NPs production was evaluated for each of the potent yeast isolates. Isolate 5 and 13 had showed highest Ag-NPs production after 24 h of incubation period, supplemented by fructose in the production medium of pH 9 along with 5mM substrate concentration of AgNO3, at 45˚C, whereas in case of isolate 8, highest production was observed with 3mM concentration of Ag NO3 at pH 8. FTIR analysis revealed the presence of significant peaks around 3441-3255, 2922-2964, 1576-1579, 1384-1415, 1276, 1153 and 1076cm-1 of Ag-NPs synthesized by isolate 5,8 and 13 respectively, were corresponding to the functional groups produced during the synthesis of Ag-NPs. XRD results showed peaks at 2 theta values 27.29°, 31.76°, 45.91°, 54.26-56.77° and 75.56-75.99°, were corresponding to (111), (200), (222), (311), and (331) lattice of silver nanoparticles. Distinct surface topology of the AgNPs synthesised by the potent yeast isolates were observed by AFM analysis. Positive anti-oxidant and anti-bacterial activity were elucidated by AgNPs synthesised by the potent yeast isolates, wherein AgNPs were found to be bacteriostatic at low concentration (5ug/ml) and bactericidal at high concentrations (100ug/ml).Keywords

The application of bioflocculants has recently become a promising solution for the treatment of water and wastewater as well as removal of pollutants from environment. Water pollution is the most challenging environmental issue in the developing countries to determine the quality of life. The wastewater from different sources contains suspended solids, organic and inorganic particles, dissolved solids, heavy metals, dyes and other impurities which are harmful to the environment causing major health hazards in human and animals. The use of bioflocculants is advantageous for the control of environmental pollution as they are non- toxic and biodegradable in nature. Moreover, they do not create any secondary pollution. Chemical flocculants being a source of carcinogens can be replaced by bioflocculants which needs to be produced on a large scale. However, commercially viable bioflocculants are yet to be produced and marketed widely. This review intends to present the updated information on microbial bioflocculants and their applications for remediation of pollutants from wastewater. It may bring up the significant issues which can be attempted by future researchers for a better understanding to develop commercially viable, safe, eco-friendly and cost effective bioflocculants using new biotechnological techniques.Keywords
