In the present study, the organisms were isolated and identified from disease infected ginger and soil sample, namely Aspergillus awamori, Aspergillus conicus, Aspergillus luchensis and Pythium aphanidermatum. The pathogenicity test was performed as two treatments i.e control and treatment. In pot culture experiment, plants were grown, control plants were not infected but treatment plants were infected by pathogen and the symptoms were observed. Trichoderma koningii, Trichoderma virens, Trichoderma harzianum and Trichoderma viride grew quickly and dominate the Pythium spp within 15 days. After 21 days, the pathogen was completely inhibited by antagonist T.koningii. The culture filtrate (non volatile) from Trichoderma koningii inhibits the growth of test microorganisms. Trichoderma koningii which is inhibitory the growth of test fungi (Pythium aphanidermatum) by 31.10% at 15% concentration. © 2016, Global Research Online. All rights reserved.

In the present study, the methanolic extract of Drynaria quercifolia rhizome was investigated for its anti inflammatory and anti pyretic activities on carrageenan-induced paw odema and brewer’s yeast-induced pyrexia in rats. The results revealed that the extract at test doses of 100, 250 & 500 mg/kg b.w produced a remarkable anti inflammatory activity at 2 ½hr with an inhibition of paw oedema of 21%, 33% and 58% respectively, compared to the reference drug dexamethasone (200mg/kg b w) with an inhibition of 40%. Among the three concentrations, dose of 500 mg showed a maximum inhibition on carrageenan-induced rat paw oedema. Anti pyretic activity was also studied on Brewer’s yeast – induced pyrexia rats. Fever was induced by injecting 10 ml/kg (s.c) of 20% aqueous suspension of Brewer’s yeast in normal saline and rectal temperature was recorded by clinical thermometer before and after 12hrs of yeast administration. Drynaria quercifolia at a doses of 100, 250, 500 mg/ kg, showed significant anti-pyretic effect by decreasing the rectal temperature. Among the three concentrations, 500mg of plant extract exhibited remarkable antipyretic activity by decreasing the rectal temperature of rats in 1 hr (38.06°C), 2hr (37.33°C), 3hr (37.09°C) after treatment which was higher than that of standard drug paracetamol (200 mg/kg) (37.24°C). These findings demonstrated that Drynaria quercifolia have remarkable anti inflammatory and anti-pyretic activities when compared with positive control and thus have great potential as a source for natural health products. © 2014, Global Research Online.

Sample was collected from rhizospheric soil. Among this study, two bacteria and two fungi were selected for siderophore production. The siderophore producing organisms were identified based on cultural, morphological and biochemical characteristics. Hence, the isolated colonies were confirmed as E.coli, Pseudomonas fluorescence, Rhizopus sp and Aspergillus flavus. By this study, analysis and nature of siderophore production was determined using these organisms. Pseudomonas fluorescens and Rhizopus sp showed the maximum catechol type of siderophore produced followed by E.coli and A.flavus minimum catechol type of siderophore. Among these, Pseudomonas fluorescens and Aspergillus flavus showed the maximum hydroxamate siderophore, followed by Rhizopus and E.coli minimum hydroxamate type of siderophore produced. Whereas, the optimization of medium for siderophore production maximum in bacteria when compared with fungi. The antibacterial activity was performed by well diffusion assay against clinical bacterial pathogens such as Streptococcus mutans, Salmonella typhi, Staphylococcus aureus and Klebsiella pneumoniae. High frequency of antibacterial activity was observed in Pseudomonas fluorescens are more efficient than the fungi Aspergillus flavus. Thus we concluded that rhizosphere soil organism producing siderophore to improve the plant growth and good antibacterial activity for clinical pathogens.

Luminescence is the emission of light by an object. Living organisms including certain bacteria are capable of luminescence. Bacteria are the most abundant luminescent organisms in nature. Bacterial luminescence is due to the action of the enzyme called luciferase. Other interesting features of marine microorganisms are having their ability to survive at low temperatures and high salinity. In the present study, marine water samples were collected from different sites of Nagapattinam sea shores, and analyzed the physicochemical characteristics. The effect of salinity, pH concentration on the growth and luminescence of these 10 strains was also studied. From the samples, bioluminescent bacterial strains were isolated using Sea Water Complex Agar and TCBS medium. Ten bioluminescent bacterial strains were isolated and identified based on cultural, morphological and biochemical charactertics which are belonged to the genera of Vibrio sp and Pseudomonas sp.

Soil is a complex ecosystem, soil beneath our foot constitute rich source of microbes whose abundance are affected by both biotic and abiotic factors. Biodiversity might help sustain multiple ecosystem functions. Fungi fulfill a range of important ecological functions, yet current understanding of fungal biodiversity in soil is limited. Soil fungi have pivotal ecological roles as decomposers, pathogens and symbionts. This study highly intend to examine the physical and chemical characteristics of the soil samples and to identify as many fungi as possible present in the four seasons of soil collected from major soil types of Thiruvarur district, Tamil Nadu. The population mean density of fungi varied from 99.99 × 10-3 cfu/g with the maximum in the samples was collected during post monsoon and monsoon season. The percentage of contribution of the individual species to the total fungal population at all the seasons showed variation. At the maximum percentage of contribution was found in Trichoderma harzianum. The occurrence of different fungal species fluctuated due to ecological and biological factors of the soil and enhanced the sufficient knowledge to the farmers for the conservation of soil properties, management of soil microbial diversity and the development of sustainable agricultural system.
