The purpose of this research is to document the cyanobacteria collected from tree bark and rock surfaces at various collection sites of Similipal Biosphere Reserve. In the present study, a total of 25 cyanobacterial species under...

Spirogyra 'water silk' is filamentous green algae grow in slow flowing lotic and shallow lentic water bodies. Intracellular metabolites were evaluated for phycochemicals and antimicrobial activity. Aqueous extract has a significant result against S. aureus followed by acetone and ethanol extract against P. aeruginosa. In the broth dilution method l...

Bhitarkanika Wildlife Sanctuary, situated in the north-eastern part of Kendrapada district of Odisha, India, spreads over an area of about 672 sq. km. Within the sanctuary, an area of approximately 145 sq.km. is designated as Bhitarkanika National Park and obtained the status of a Ramsar site on 19th August 2002. It is the second largest mangrove e...

Microalgae have the ability to produce natural bioactive chemicals that are difficult to synthesize chemically. Natural antioxidants derived from microalgal sources may be effective substitutes for manufactured antioxidants due to their antibacterial action and low side effects. The influence of several solvents on phytochemical screening, antioxid...

Phyco-remediation of wastewater through microalgae is a promising area; hence, the study focused here is to analyse the growth and biochemical constituents of waste-grown microalgal strain collected from municipality wastewater of Baripada and industrial effluents of Emami Paper Mill, Balasore. Effluent samples were collected and brought to laborat...

Present investigation records diversity of pennate diatom species belonging to seven genera viz. Thalassionema, Nitzschia, Bacillaria, Psammodictyon, Hantzschia, Haslea and Diploneis, in brackish water of Budhabalanga river estuary, Odisha coast. The study comprises morphological and taxonomical enumeration of the species found in samples of the es...

In the present work, the green synthesis method was adopted to synthesize electronically charged silver nano-particles utilizing the leaf extract of Abutilon indicum collected from Similipal Biosphere Reserve, Baripada, India. The synthesized silver nanoparticles (AgNPs) were characterized by spectroscopic methods such as UV-Vis, FT-IR spectroscopy...

Traditional medicine is used in all over the world, especially in developing countries. Recently importance is given to the green medicine. Though synthetic drugs are very effective but are harmful to human beings because of different side effects. Plants of Terminalia species are belong to the family Combretaceae, which contains 20 genera and 600...

Bio- synthesis of silver nanoparticles (AgNPs) was made by using the aqueous leaf extract of Ardisia solanacea. Rapid formation of AgNPs was observed from silver nitrate upon treatment with the aqueous extract of A. solanacea leaf. The formation and stability of the AgNPs in the colloidal solution were monitored by UV–visible spectrophotometer. The...

It is an edited book compiling various studies on biodiversity, anthropology and social issues of Similipal Biosphere Reserve.

Silver nanoparticles play an integral part in the evolution of new antimicrobials against the broad ranges of pathogenic microorganisms. Recently, biological synthesis of metal nanoparticles using plant extracts has been successfully consummated. In the present study, the biosynthesis of silver nanoparticles (AgNPs) was conducted using the leaf ext...

The present investigation focused on screening of antibacterial and antioxidant potential of phytochemicals extracted from a corticolous cyanobacterium Hassalia byssoidea isolated from Similipal Biosphere Reserve situated in the Mayurbhanj district of Odisha. Different phytochemicals were extracted with petroleum ether, chloroform, acetone, methano...

In this experiment, biosynthesized silver nanoparticles (AgNPs) were synthesized using aqueous leaf extract of Erythrina suberosa (Roxb.). The biosynthesis of silver nanoparticle was continuously followed by UV-vis spectrophotometric analysis. The response of the phytoconstituents resides in E. suberusa during synthesis of stable AgNPs were analyze...

The present study reports on biogenic-synthesised silver nanoparticles (AgNPs) derived by treating Ag ions with an extract of Cassia fistula leaf, a popular Indian medicinal plant found in natural habitation. The progress of biogenic synthesis was monitored time to time using a ultraviolet–visible spectroscopy. The effect of phytochemicals present...

Abstract: Cyanobacteria and microalgae are important components of biological soil crusts (BSC) as they improve soil structure, stabilize soil erosion, enhancing plant seedling establishment and increase of infiltration of rain water into soil. During present study, algal samples were collected from 3 sampling sites namely Badamakabadi, Chahala and...

In the present study, the green synthesis method was adopted to synthesize bioactive silver nano-particles utilizing the leaf extract of Garuga pinnata Roxb., a potential medicinal plant collected from Similipal Biosphere Reserve, Baripada, India. Garuga pinnata Roxb. is well known for its ethnomedicinal properties against gastrointenstinal problem...

Rice beer, popularly known as Handia, is a fashionable drink among the tribals of northern Odisha. It influences their social, cultural and economic life. It is prepared in almost every third house following traditional knowledge. Different parts of 20 plant species are utilized for the preparation of ranu or bakhar tablets which act as starter cul...

The context and purpose of the study: To explore the available plants used for starter preparation of Handia, their ethnomedicinal uses and to screen phytochemical constituents for antibacterial activity against enteric pathogens. The main findings: Semi-structured interview was carried out with 24 informants (mean age 46, male) from 24 locations....

This paper deals with ethnomedicinal uses and anti-diarrheal properties of medicinal plants used by the tribal people of District Mayurbhanj, Odisha, India. Aqueous and methanol extracts of 72 plants were tested for antibacterial activity using agar well diffusion (sample concentration of 100 mg/ml) against eight pathogenic bacteria responsible for...

Antibacterial activity of organic and aqueous extracts from bark of Terminalia arjuna Roxb. was examined against diarrhea causing bacteria viz. Shigella boydii, S. dysentriae, S. flexneri, S. sonnei, Salmonella typhimurium, Escherichia coli, E. coli O157:H7, Bacillus cereus and Staphylococcus aureus. The minimum inhibitory concentration (MIC) was r...
