    The green revolution strategy, which promotes the use of synthetic agricultural chemicals like pesticides and fertilizers, the adoption of high-yielding, nutrient-responsive crop varieties, increased irrigation potential exploitation, etc., has, for the most part, increased production output. However, it will also cause a decline in the productivity and production of various crops as well as harm to the environments and soil health. Plant Growth Promoting Rhizobacteria (PGPRs) have special functions in the soil that improve the health and productivity of plants. PGPR produce phytohormones, fix atmospheric nitrogen, colonize the rhizosphere, aid in the production of secondary metabolites, shield plants from pathogens, produce siderophores, and aid in the uptake of nutrients by solubilizing phosphate. They also produce biologically active substances that have an impact on the development and growth of plants. In the present investigation, the fungicidal activities of Streptomyces sp., the significant PGPRs were screened for antifungal activities while an Entomopathogenic fungi (Baeuveria bassiana) was utilized for production of crude metabolites which were utilized to prepare Silver fused nanoparticles, the nanoparticles were found to have significant insecticidal/pesticidal properties against larvae invading Cauliflower crops

    The purpose of the present research work was to formulate, evaluate, and optimize self-emulsifying formulation to enhance drug release. The solubility of formulation was determined in different natural oils, surfactant, and co-surfactants. Self-emulsifying drug delivery system (SEDDS) was prepared by using castor oil, Tween 80, and Carbitol as co-surfactant. S-SEDDS evaluated for globule size and emulsification time. A 32 full factorial design was utilized for the optimization purpose. Formulation variables such as quantity of oil (X1) and ratio of surfactant to co-surfactant (X2) were investigated for their effect on globule size and emulsification time. Optimized formulation with minimum globule size was freeze-dried and finally, optimized formulation evaluated for the in vitro drug release study. To recognize the capable self-emulsifying zone, pseudo-ternary phase diagrams were prepared. For knowing the interaction behavior of desired responses, the Box-Behnken framework was used and configured using the appropriate method. At the last, the selected optimized formulation was tested for droplet size analysis, phase separation study, self emulsification time, transmittance, turbidity analysis, and zeta potential. Based on results it is concluded that SMEDDS can be a better choice to optimize the oral delivery of losartan potassium.&nbsp

    276-285Sweet potato [Ipomeabatatas(L.) Lam.]is a nutritious food crop primarily grown by small and marginal farmers. Successful breeding and germplasm conservation programs demands characterization of its germplasm. Here, we tried to determine genetic diversity among 21 sweet potato genotypes using morphological, biochemical and molecular markers. Ten morphological traits were studied and subjected to analysis of variance (ANOVA). Mean square due to germplasm were highly significant as well as wide mean range performance was observed for tuber number per plant, individual tuber weight, tuber fresh yield per plant, tuber dry yield per plant, tuber yield per plot and tuber length. UPGMA (Unweighted Pair Group Method Arithmetic Average) cluster analysis based on morphological traits separated the germplasm into three groups. The genotypes Gautam, Shree Arun, RS-92 and CO-3-4 appeared promising with regard to yield characters. Total phenol was maximum in in V-12 genotype (1.39 mg), while minimum was recorded in Samrat genotype (0.95 mg). The highest total antioxidant was observed in the genotype Samrat (0.30 mg), while minimum was recorded in the genotype Navsari Local (0.16 mg). Molecular diversity analysis was carried out using 25 RAPD (Random Amplified Polymorphic DNA) primers, out of which 13 primers produced 117 reproducible amplicons (106 polymorphic, 7 monomorphic and 4 unique amplicons). UPGMA dendogram based on RAPD data separated the genotypes into two major clusters having the similarity coefficient ranged from 0.56 to 0.76. The results can be used for sweet potato crop improvement through molecular breeding and marker assisted selection of for desired traits in future

    Bioremediation of tannery wastewater using Tetradesmus deserticola: A sustainable approach

    Get PDF
    This study aimed to evaluate the potential of Tetradesmus deserticola for the bioremediation of tannery wastewater (TWW), which contains both organic and inorganic pollutants that are harmful to the environment and human health if discharged untreated. The methodology involved culturing T. deserticola in different concentrations of TWW and assessing its ability to remove pollutants over 15 days. The physicochemical analysis of the treated TWW revealed significant reductions in key parameters, such as Chemical Oxygen Demand (COD) (93.6%), total nitrogen (93.3%), phosphate (79.8%), magnesium (95.9%), and heavy metals including chromium (92.9%), zinc (82.4%), and iron (63.6%). Gas chromatography-mass spectrometry (GC-MS) analysis confirmed the effective remediation of carcinogenic aromatic compounds, including benzene derivatives, and the transformation of complex steroids into less toxic metabolites. However, long-chain alkanes largely remained unaffected by the microalgal treatment. These findings suggest that T. deserticola can effectively remediate TWW, offering a promising and sustainable solution for wastewater treatment. Further optimization of treatment conditions may enhance the degradation of persistent compounds
