Soumendranath Chatterjee; Indranil Bhattacharjee; Goutam Chandra

The metal binding capacity of the thermophilic bacteria Geobacillus thermodenitrificans isolated from Damodar river, India was assessed using synthetic metal solutions and industrial waste water. Biosorption preference of dead biomass of G. thermodenitrificans for the synthetic metal solutions was in the following order Fe(+3)>Cr(+3)>Co(+2)>Cu(+2)>Zn(+2)>Cd(+2)>Ag(+)>Pb(+2). It reduced the concentration of Fe(+3) (91.31%), Cr(+3) (80.80%), Co(+2) (79.71%), Cu(+2) (57.14%), Zn(+2) (55.14%), Cd(+2) (49.02%), Ag(+) (43.25%) and Pb(+2) (36.86%) at different optimum pH within 720 min. When this strain was applied in the industrial waste water biosorption preference was in the following order Fe(+3)>Cr(+3)>Cd(+2)>Pb(+2)>Cu(+2)>Co(+2)>Zn(+2)>Ag(+) and concentrations reduced up to 43.94% for Fe(+3), 39.2% for Cr(+3), 35.88% for Cd(+2), 18.22% for Pb(+2), 13.03% for Cu(+2), 11.43% for Co(+2), 9.02% for Zn(+2) and 7.65% for Ag(+) within 120 min.

Indranil Bhattacharjee; Soroj Kumar Chatterjee; Soumendranath Chatterjee; Goutam Chandra

The sensitivity of two Gram positive (Staphylococcus aureus and Bacillus subtilis) and two Gram negative (Escherichia coli and Pseudomonas aeruginosa) pathogenic multi-drug resistant bacteria was tested against the crude extracts (cold aqueous, hot aqueous, and methanol extracts) of leaves and seeds of Argemone mexicana L. (Papaveraceae) by agar well diffusion method. Though all the extracts were found effective, yet the methanol extract showed maximum inhibition against the test microorganisms followed by hot aqueous extract and cold aqueous extract.

A review on Anopheles subpictus Grassi--a biological vector.

Goutam Chandra; Indranil Bhattacharjee; Soumendranath Chatterjee

Anopheles subpictus is a complex of four isomorphic sibling species A, B, C and D and is recognized as a primary vector of malaria, a disease of great socio-economic importance, in Australasian Zone, Celebes, Portuguese Timor and South East Asia and a secondary vector in Sri Lanka. This species is also a vector of some helminth and arboviruses. This species has been reported so far from nineteen countries of the Oriental and Australasian Zones. An. subpictus complex is the most abundant anopheline in most parts of the Indian subcontinent, with a widespread distribution eastwards and southwards to Papua New Guinea, westwards to Iran and northwards to China. Resistance to insecticide is alarming in many parts of the world. Different aspects of this important mosquito species including attempts related to its control have been discussed which will be highly useful to carry out further research.

Bactericidal Activities of Some Common Herbs in India

Soumendranath Chatterjee; Indranil Bhattacharjee; Goutam Chandra

Abstract The bactericidal activities of the aqueous and methanol extracts of the leaves of three plants used as popular medicine in India were studied. The dried leaf extracts of Vangueria spinosa. B. (Rubiaceae), Cestrum nocturnum. L. (Solanaceae), and Nyctanthes arbortristis. L. (Oleaceae) were tested in vitro. by the disk diffusion method against four bacterial strains, namely, Staphylococcus aureus. (MTCC 2940), Bacillus subtilis. (MTCC 441), Escherichia coli. (MTCC 739), and Pseudomonas aeruginosa. (MTCC 2453). Both the aqueous and the methanol extracts of V. spinosa. showed the strongest activity, followed by C. nocturnum. and N. arbortristis.. The only exception was P. aeruginosa., which, in turn, was found to be resistant against the aqueous extract of N. arbortristis.. Aqueous extracts of the leaves of all the plants appeared to have less antibacterial activity than the methanol extracts.

Phytase-Producing Rhodococcus sp. (MTCC 9508) from Fish Gut: A Preliminary Study

Argha Khan; Sudipta Mandal; Dhritiman Samanta; Soumendranath Chatterjee; Koushik Ghosh

Isolation and enumeration of autochthonous heterotrophic gut microbiota from four carps (Labeo rohita, Catla catla, Hypophthalmichthys molitrix and Labeo bata) has been carried out. Gut isolates were analyzed qualitatively for extracellular amylase, protease, cellulase and lipase producing capacities and four superior isolates were further studied for phytase producing capabilities. The isolate CC1.1 (Rhodococcus sp. MTCC 9508) isolated from C. catla seemed to be the best phytase producer amongst the isolates studied. Bio-safety of the isolate was evaluated in vivo by injecting fresh broth culture to healthy laboratory acclimatized rohu, L. rohita. Presence of autochthonous phytase producing Rhodococcus sp. detected in the present study offers scope for further research to appraise its potential application in commercial aquaculture.

Helminth–bacteria interaction in the gut of domestic pigeon Columba livia domestica

Debraj Biswal; Anadi Prasad Nandi; Soumendranath Chatterjee

The present paper is an attempt to study the interaction between the helminth parasite and bacteria residing in the gut of domestic pigeon, Columba liviadomestica. Biochemical and molecular characterization of the gut bacterial isolate were done and the isolate was identified as Staphylococcus sp. DB1 (JX442510). The interaction of Staphylococcus sp. with Cotugnia cuneata, an intestinal helminth parasite of domestic pigeon was studied on the basis of the difference between ‘mean worm burden’ of antibiotic treated infected pigeons and infected pigeons without any antibiotic treatment. The ANOVA and Tukey tests of the data obtained showed that antibiotic treatment reduced the mean worm burden significantly. The biochemical properties of Staphylococcus sp. DB1 (JX442510) also showed a mutualistic relationship with the physiology of C. cuneata.

Spatial distribution & physicochemical characterization of the breeding habitats of Aedes aegypti in & around Kolkata, West Bengal, India.

Soumendranath Chatterjee; Arunima Chakraborty; Shuvra Kanti Sinha

Background & objectives: Dengue infection is endemic in several areas and the dengue virus is transmitted by Aedes mosquitoes. Thus, it becomes important to understand the breeding ecology of dengue vector and characterize the physicochemical parameters of its breeding habitat. The objective of this study was to analyze the physicochemical parameters of the breeding habitat of the dengue vector and to find out the nutrient composition of the habitat in and around Kolkata, West Bengal. In addition, a geographic information system (GIS) was used to map the disease prone areas for its effective management and prevention. Methods: Water samples were collected from various breeding habitats of Aedes mosquitoes of Kolkata and adjoining areas and were analysed for various physicochemical properties like acidity, alkalinity, hardness, electrical conductivity, total dissolved solids, concentration of chloride (Cl-), sodium (Na+), potassium (K+), fluoride (F-) in relation to larval prevalence. Results: Parameters like water pH, total dissolved solids, total hardness, electrical conductivity, concentration of chloride, sodium and potassium were seen to vary throughout the year. Certain parameters were found to be dependent on container type, like concentration of fluoride. Significant positive correlations were seen between per dip larval density and total dissolved solids (TDS) and electrical conductivity. Interpretation & conclusions: Water pH, electrical conductivity, total dissolved solids were seen to play a major role in the ovipositional preferences. Container type did not seem to affect TDS. Tyres had the highest TDS in most of the cases. Nutrient composition like sodium concentration was mostly found in the coconut shells, potassium concentration also showed the same. Thus, container type and various parameters and nutrients play a major role in determining where a gravid female mosquito will lay its eggs. It was observed that by altering various chemical and physical properties of breeding habitats it was possible to control the larvae survivability.

Temporal variation of the cestode, Cotugnia cuneata (Meggit, 1924) in their host, domestic pigeons, Columba livia domestica (Gmelin, 1789)

Debraj Biswal; Anadi Prasad Nandi; Soumendranath Chatterjee

A study of the temporal variation of Cotugnia cuneata, on a monthly basis, was carried out from January 2008 to December 2010. The study revealed a similarity in the percentage prevalence and mean intensity of infection with higher values in the beginning of the year that gradually declined towards the middle and rose to moderate values towards the end of the year. The periodicity clearly shows a correlation with the seasonal changes throughout the year and provides important insights to the survival strategies of the parasite as well as its life-cycle.
