Actinomycete Isolates from Arabian Sea and Bay of Bengal: Biochemical, Molecular and Functional Characterization

The thesis is comprised of seven chapters. Chapter 1 gives a general introduction to marine actinomycetes; Chapter 2 gives an account on the morphological, biochemical and physiological characterization of marine actinomycetes. Comprehensive description of molecular identification and phylogenetic analysis of actinomycetes is dealt with in Chapter 3. The antimicrobial property with special reference to antivibrio activity is described in Chapter 4. Chapter 5 explores the melanin production ability of marine actinomycetes, characterization of melanin and evaluation of its bioactivity. Chapter 6 illustrates the study on chitinolytic Streptomyces as antifungal and insecticidal agents. Summary and Conclusion of the study is presented in Chapter 7, followed by References and Appendices.The present study provides an insight into the various actinomycetes occurring in the sediments of Arabian Sea and Bay of Bengal. Streptomyces was found to be the dominant group followed by Nocardiopsis. Eventhough generic level identification is possible by traditional phenotypic methods, species level identification necessitate a polyphasic approach including both phenotypic and genotypic characterization. Antibiotic production coupled with biogranulation property helped in the effective utilization of the actinomycetes for the control of vibrios. Melanin from Streptomyces bikiniensis was proved to be a promising antioxidant and photoprotectant. Marine actinomycetes were found to be a good source of hydrolytic enzymes and the chitinolytic isolates could be explored as biocontrol agents in terms of antifungal and insecticidal property. The present study explored the potential of marine actinomycetes especially Streptomycetes as a promising source of bioactive molecules for application in aquaculture and pharmaceutical industry.

Pecha Kucha: Bay 8

Abstract Following the success of Bay 9's Pecha Kucha, this week Bay 8 are providing the next instalment of the newly established tradition of Pecha Kucha. In 6m40s and 20 slides, each member of Bay 8 will introduce themselves, explaining their background and research interests, so you can put a name to the face, and chat after the event if you have common interests. These mini talks aim to support the collaborative nature of WAIS by introducing each member to the wider group. This week the bay members and Pecha Kuchas are: - The Public Health Analogy in Web Security (Huw) - Social Networking Features in Digital Behaviour Change Interventions (Roushdat) - Computers, Psychology and a lot of coffee (Anna) - Law, computer science and that annoying thing you have to say you’ve read before you can use a website (Emma)

Bay 13 pecha kucha

The talks are by EA Draffan, Nawar Halabi, Gareth Beeston and Neil Rogers. In 6m40s and 20 slides, each member of Bay 13 will introduce themselves, explaining their background and research interests, so those in WAIS can put a name to a face, and chat after the event if there are common interests.
