In vitro study on the effect of four Trichoderma isolates on the mycelial growth of Rhizoctonia solani showed maximum inhibition of 74.54 per cent and least inhibition of 52.50 per cent. Effects of volatile compound produced by Trichoderma spp. against R. solani were ranged from 15.50 to 26.70 per cent.

This paper investigated the influence of semantic priming and word frequency on visual word recognition by native speakers of English. Three experiments were conducted to throw light on the mechanism of meaning activation based on how the homographs were processed in isolation and in contexts with semantic priming. The homographs used in the present study were ones with the same spellings, but with different pronunciation and meanings.

Combination of Rhizobium and Trichoderma species were studied to document their compatibility their synergism, antagonism under in vitro condition and their effects on the growth of lentil in vivo condition. In respect this, few strains of Trichoderma were isolated from the rhizosphere soil of Pulse crop from different locations of West Bengal and they were tested in vitro and in vivo along with Rhizobium to know the interaction between them and the growth behaviour on lentil.

Rice is an important staple food for more than half of the world’s population and is subject to diseases that often place major biological constraints on production. Sheath blight of rice is caused by a soil borne fungus and biological control of the disease is an efficient substitute to replace chemical methods. In the present study thirty native fluorescent Pseudomonads, an efficient biocontrol agent have been isolated and confirmed by cultural, morphological, biochemical characterization and visualization under UV light.

Green nanomaterials have gained much attention due to their potential use as therapeutic agents. The present study investigated the production of silver nanoparticles (AgNPs) from a silver-resistant Bacillus safensis TEN12 strain, which was isolated from metal contaminated soil and taxonomically identified through 16S rRNA gene sequencing. The formation of AgNPs in bacterial culture was confirmed by using UV–vis spectroscopy with an absorption peak at 426.18 nm.

The aim of the study was to access the anti-bacterial and anti-fungal activity on the growth of Alternaria porri under in vitro condition. The antagonistic activity of bacterial and fungal antagonists (Pseudomonas and Trichoderma spp.) was determined by the dual culture technique both on King’s B and PDA media respectively, Paper disc assay and Agar well mathod. Plates were incubated at 28ºC for 7 days and 2 days. The antagonistic activity of these antagonists was evaluated by mycelial growth and mycelial dry weight of test fungus (Alternaria porri).

The present study was undertaken to analyze the effect of the native Trichoderma spp., isolated from the rhizosphere of ghost pepper (Capsicum chinense) against root rot caused by Rhizoctonia solani. Rhizospheric Trichoderma spp. were isolated from ghost pepper growing sites of Manipur and screened for their biocontrol potential against Rhizoctonia solani. Four fungal isolates were isolated and selected based on morphology and growth pattern. Molecular identification was carried out and an amplicon size of 262 bp were generated for fungus.

An attempt was made to isolate, screen, and evaluate the different Plant Growth Promoting Rhizomicrobial consortia on growth parameters of sweet corn (Zea mays convar. saccharata var. rugosa). In the course of the study, as many as five Acetobacter, four phosphate solubilizing bacteria and four potassium solubilizing bacterial isolates were isolated from the rhizosphere soils of Malnad regions. Further all the isolates were screened under in vitro condition. Out of five Acetobacter isolates, Aceto-5 fixed a maximum of 4.8mg of nitrogen/g of carbon source.

Sclerotium rolfsii Sacc, [teleomorph: Athelia rolfsii (Curzi)] causing collar rot of chickpea, is a devastating soil-borne fungus. It is reported almost all over the world with 10 to 30% yield loss is recorded annually according to severity of the disease. It is more serious at seedling stage causing plant mortality ranged from 54.7 to 95%. The present investigation was undertaken to find out bio-efficacy of twenty native isolates of Trichoderma spp.

In vitro antagonism of native biocontrol agents on coconut pathogens revealed that all the three isolated native Trichoderma spp were found inhibitory to the mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora. Maximum percent inhibition of mycelia growth of Thielaviopsis paradoxa and Phytophthora palmivora was obtained by Trichoderma viride followed by Trichoderma hamatum and Trichoderma harzianum.

An attempt was made to screen forty native AM fungal isolates from the soybean rhizosphere of Belagavi and Dharwad districts based on their peroxidise activity and total dry matter accumulation in soybean under the restricted water regime of -500 kPa. Top three fungal isolates viz., UASDAMFS15, UASDAMFS25 and UASDAMFS36 tentatively identified as G. maculosum, G. manihotis and G. globiferum respectively. For pot culture studies three irrigation regimes were maintained viz., -33 kPa -500 kPa and -1000 kPa. An experiment was laid out in completely randomized design with factorial concept.

Petroleum-based products are the major source of energy for industry and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. Crude oil-impacted tropical soil and natural water samples (0 - 30cm depth) were obtained from the Niger Delta, Nigeria. A total of twenty seven bacterial species of relevance in bioremediation were isolated and characterized using standard and conventional methods. The predominant species belong to the genera Pseudomonas and Proteus.

The potent native bioagents isolated from tomato rhizosphere have high antagonistic potential against Phytophthora infestans. Molecular characterization of fungal isolates (T-11 and T-14) was performed by using Internal Transcribed Spacer (ITS) region of 18S rRNA sequence. The sequence analyses of two isolates (MK928414 and MK928417), showed 100% similarity with Trichoderma asperellum during BLAST analysis. The phylogeny tree constructed by using sequence analysis showed the formation of cluster along with T. asperellum and both the isolates were identified as T. asperellum.

Current research efforts are directed towards native entomopathogenic fungi which are highly virulent to insect pests to develop efficient and eco-friendly bio-pesticides. From the insect cadavers fifteen different fungal isolates were isolated on DOC2-50% selective media and were identifying as isolates of Aspergillus tamari, A. niger and A. flavus. All the fifteen isolates showed variation in all the morphological characters studied. Highest mean colony diameter (mm) was reported in isolate EPF-14 at all the time intervals.

Soybean [Glycine max (L.) Merrill] is a legume known for nitrogen fixation interacting with efficient Bradyrhizobium strains. In Côte d'Ivoire, the Bradyrhizobium inoculums used in soybean production is a foreign strain, which requires the search for indigenous strains adapted to Ivorian soils. The present study aimed to isolate and select rhizobial bacteria from soybeans grown on soils sampled from six localities in the central-western region of Côte d'Ivoire.

Studies were conducted on Carnation (Dianthus caryophyllus L.) to find out the effect of integrated inoculation of potent native isolates of Arbuscular mycorrhizal fungi (AM fungi) and Azotobacter chroocococum with other approaches of management like cultural and biological methods in solarized soil on the incidence of wilt caused by Fusarium oxysporum f.sp. dianthi (Prill. and Del.). Initially, organic amendments, botanicals and bio-control agents were evaluated against wilt to find out the best treatments. Among amendments, neem cake was found most effective with 75.

The present study principally sought to investigate the effect of green tea extract (GTE) supplementation on hepatic mitochondrial DNA (mtDNA) damage in alcohol receiving rats. MtDNA was isolated from hepatic tissues of albino wistar rats after alcohol treatment with and without GTE supplementation. Entire displacement loop (D-loop) of mtDNA was screened by PCRSanger’s sequencing method. In addition, mtDNA deletions and antioxidant activity were measured in hepatic tissue of all rats. Results showed increased frequency of D-loop mutations in alcoholic rats (ALC).
