| 1 | Antibacterial potential of sponge endosymbiont marine Enterobacter sp at Kavaratti Island,Lakshadweep archipelago显示文摘Objective:To isolate antibacterial potential of sponge endosymbiotic bacteria from marine sponges at Lakshadweep archipelago.Also to identify the potent bacteria by 16s rDNA sequencing and determine the antibacterial activity against clinical pathogens by MIC.Methods: Sponge samples was collected from sub-tidal habitats at Kavaratti Island and identified.The endosymbiotic bacteria were isolated and selected potential bacteria which show antibacterial activity in preliminary screening against clinical pathogens Staphylococcus aureus(S.aureus), Escherichia coli(E.coli),Salmonella typhi(S.typhi),Klebsiella pneumoniea(K.pneumoniea) and Streptococcus sp.by disc diffusion assay.The crude extracts of potential bacteria LB3 was tested against clinical pathogens by MIC.The LB3 strain was identified by 16s rDNA sequencing, 1111 bp was submitted in NCBI(HQ589912) and constructed phylogenetic tree.Results:Sponge sample was identified as Dysidea granulosa(D.granulosa) and potential bacteria LB3 identified as Enterobacter sp TTAG.Preliminary screening of sponge isolates against clinical pathogens,LB3 strain was selected as potential producer of secondary metabolites and crude extract was implies on MIC of LB3 have confirmed with lowest concentration of 5.0 mg/mL in broth medium influence of crude extract on growth inhibitory activity after 5 h of incubation period and completed the inhibitory activity at 15 h.Conclusions:The present study concluded that phylogenetic analysis of endosymbiotic bacteria Enterobacter sp from sponge D.granulosa of Lakshadweep islands showed significant antibacterial activity against clinical bacterial pathogens. | Mohan Gopi Subramanian Kumaran Thipparamalai Thangappanpillai Ajith Kumar Balaraman Deivasigamani Kumarappan Alagappan Srinivasan Guru Prasad | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，2： | 2 |

| 8 | Fixed Point Theorems for Weakly Contractive Mappings in Ordered Metric Spaces with an Application显示文摘In this paper,we prove fixed point theorem for weakly contractive mappings using locally T-transitivity of binary relation and presenting an analogous version of Harjani and Sadarangani theorem involving more general relation theoretic metrical notions.Our fixed point results under universal relation reduces to Harjani and Sadarangani[Nonlinear Anal.,71(2009),3403-3410]fixed point theorems.In this way we also generalize some of the recent fixed point theorems for weak contraction in the existing literature. | Gopi Prasad Ramesh Chandra Dimri | 2022 | Analysis in Theory and Applications2022，38，2： | 0 |
| 9 | Fixed Point Theorems in Relational Metric Spaces with an Application to Boundary Value Problems显示文摘In this paper,we establish fixed point theorems for generalized nonlinear contractive mappings using the concept of w-distance in relational metric spaces.Thus we generalize the recent results of Senapati and Dey[J.Fixed Point Theory Appl.19,2945-2961(2017)]and many other important results relevant to this literature.In order to revel the usefulness of such investigations,an application to first order periodic boundary value problem are given.Moreover,we furnish a non-trivial example to demonstrate the validity of our generalization over previous existing results. | PRASAD Gopi KHANTWAL Deepak | 2021 | Journal of Partial Differential Equations2021，34，1： | 0 |
