Industrial wastes are capable of polluting the soil and groundwater. The tanning industry is considered as a potential environmental agent through out world. Chromium (Cr), toxic heavy metal, major constituent tannery waste, its accumulation in water causes serious issues increasing public concern India particularly Tamil Nadu. present study deals with isolation identification chromium reducing bacteria isolated from effluent collected Crompet, Chennai, Nadu (latitude 12°57′51.8″N longitude...
The endophytic fungus is have rich source of secondary metabolites which act as biological active agent in the higher plants. fungal derivatives play vital part human life and their compounds are drug for cancer, microbial viral diseases. natural from endophytes acts growth inhibitor plant pathogenic organism. Endophytes sources products used agriculture (plant insecticidal), pharmaceutical industries also phytoremediation.
Marine microbes are potential source for novel metabolites. They efficient in producing these metabolites utilizing agrowastes. Protease is one of the enzymes which find wide industrial applications. In present study, protease bacteria was isolated from marine sediments and organism identified as Bacillus halodurans. The subjected to production under solid state fermentation (SSF) using different agrowastes substrates. Among substrates used, wheat bran yielded maximum quantity protease....
With a view to develop an ecofriendly botanical pesticide, we evaluated the bioefficacy of crude extracts Couroupita guianensis against third instar larvae Helicoverpa armigera. Maximum feeding deterrency (81.67%) and least LC50 (2.72%) for larval mortality were seen in hexane extract. Hexane extract was subjected column chromatography using different ratio hexane-ethyl acetate solvent system. Totally eight fractions collected. The screened at 125, 250, 500 1,000 mg/kg concentrations H....
Three-dimensional printing (3DP) is revolutionizing pharmaceutical sciences and biomedical applications by offering unprecedented precision, efficiency, personalization in drug formulation medical device manufacturing. It enables the production of tailored dosage forms with controlled release profiles, making it highly suitable for treating complex diseases such as epilepsy, cancer, cardiovascular disorders. 3DP also facilitates creation polypills, enhancing therapeutic compliance reducing...
The present study, deal about the antibiosis activity of soil bacteria, isolated from 10 different locations rhizosphere and diverse cultivation at Kochi, Kerala, India. bacteria were by standard serial dilution plate techniques. Morphological characterization isolate was done Gram's staining found that all them gram positive. Isolated tested against 6 human pathogens viz., Escherichia coli, Enterococcus sp., Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus Acinetobacter...
The present work describes purification and characterization of an extracellular cellulase from a newly isolated cellulolytic bacterial strain Bacillus pumilus EWBCM1. candidate was tested for its abilities to hydrolyze the structural polysaccharides through depolymerising activities carboxymethylcellulase. carried out by ammonium sulphate precipitation, DEAE cellulose sephadex G-100. Purified found be 47.56 fold along with 1.46 U/mg protein molecular weight 47 kDa SDS-PAGE electrophoresis....
The intention of the study was evaluated for purification and characterization exopolysaccharides from
Bioefficacy of leaf and root extracts Aristolochia tagala Cham. at different concentrations was evaluated room temperature against Spodoptera litura Fab. Effects on feeding, larvicidal pupicidal activities larval-pupal duration were studied. Higher antifeedant activity (56.06%), lethal concentration for feeding inhibition (3.69%), (40.66%), (28%), total mortality (68.66%) prolonged (12.04-13.08 days) observed in ethyl acetate extract 5.0% concentration. Dose dependant effect test observed....
Abstract BACKGROUND The triterpenoid friedelin isolated from hexane extract of Azima tetracantha leaves was evaluated for its antifeedant, larvicidal and pupicidal activities against Helicoverpa armigera Spodoptera litura at 125, 250, 500 1000 ppm concentration. RESULTS Friedelin exhibited antifeedant (84.57 75.28%), (72.88 66%) (76.18 66.66%) H. S. respectively. homogeneity variances (Levene statistic) showed significant deviation the . It LC 50 values 130.47 226.41 509.56 607.99 In linear...
Many synthesized semiconductor QDs materials are formed using trioctylphosphine oxide (TOPO) but it requires high temperature, is very expensive and also hydrophobic. Our study deals with selective syntheses of CdSe core-shell CdSe/ZnS quantum dots (QDs) in aqueous solution by a simple heating refluxing method. It more hydrophilic, needs less economically viable eco-friendly. Bio-ligands, such as thioacetamide, itaconic acid glutathione, were used stabilizers for the biosynthesis QDs. A...
To evaluate the efficacy of Atalantia monophylla (A. monophylla) leaf in different solvent crude extracts and fractions against eggs Spodoptera litura (S. litura). Hexane, ethyl acetate chloroform A. 12 from hexane extract were screened at 5.0%, 2.5%, 1.0% 0.5% for 1 000, 500, 250 125 mg/kg S. ovicidal activity. LC50 LC90 calculated using probit analysis. Hexane showed maximum activity 61.94% 5.0% concentration with a correlation value r2=0.81, least 3.06%. was fractionated silica gel column...
Tribolium castaneum is one of the major pests stored grains which causes extensive damages. To control this insect pest many synthetic chemical pesticides are used. However, continuous usage fumigants resurgence, toxic residues, genetic resistance in pests, environmental contamination and health hazards etc., avert these problems, essential oils used as bio-fumigants to pests. They could act best alternatives fumigant closed environment. Hence, present study aimed evaluate pesticidal...
Abstract Bioefficacy of hexane, chloroform and ethyl acetate extracts the seeds Ceasalpinea bonduc (L.) Roxb. was studied against third instar larvae Spodoptera litura at 0.25, 0.5, 1, 2.5 5.0% concentrations. Significant antifeedant, larvicidal pupicidal activities least LC50 values were observed in extract. The extract subjected to fractionation using silica gel column chromatography. Six fractions obtained; among these, fraction showed high 1000 ppm concentration. Abnormalities adults...
Larvicidal activity of pectolinaringenin from Clerodendrum phlomidiswas evaluated against Anopheles stephensi and antifeedant, larvicidal growth inhibitory activities were Earias vittella. Pectolinaringenin exhibited 100 98.24% 2nd 4th instar larvae at 5ppm concentration. It LC50 values 0.35 0.55 ppm for larvae, respectively. At concentration, maximum antifeedant 74.00% 89.98%.
