Domain swapping and generation of chimeric insecticidal crystal protein is an emerging area insect pest management. The lepidopteran pest, gram pod borer (Helicoverpa armigera H.) wreaks havoc to chickpea crop affecting production. Lepidopteran insects were reported be controlled by Bt (cryI) genes. We designed a plant codon optimized gene (cry1Aabc) using three domains from different cry1A genes (domains I, II, III cry1Aa, cry1Ab, cry1Ac, respectively) expressed it under the control...
Aim: To select a toxin combination for the management of maize stem borer (Chilo partellus) and to understand possible mechanism synergism among Bacillus thuringiensis Cry1A toxins tested. Methods Results: Three were over expressed in Escherichia coli strain JM105 used diet overlay insect bioassay against C. partellus neonate larvae, both alone combinations. Probit analysis revealed that three tested have synergistic effect larvae. In vitro binding fluorescein isothiocyanate (FITC)-labelled...
A feeding trial of 60 days was conducted to delineate the effect dietary synbiotic on maximum growth, body composition, digestive enzyme activity and subsequently gut microbiota in Cirrhinus mrigala fingerlings. One hundred eighty acclimatized fingerlings mrigal with initial weight ranging from 2.87 ± 0.01 g 3.26 0.05 were randomly distributed three replicates each four experimental groups including control (without probiotic prebiotic), T1 (high + low T2 (low high prebiotic) T3 using...
Abstract An experiment was conducted for 60 days in a 500L capacity FRP tank containing inland ground saline water (fortified to level of 50% potassium) with one control (sediment) and three treatments; T1(Paddy Straw Biochar (PSB) sediment), T2 (Banana Peduncle (BPB) T3 (PSB + BPB sediment). (100 g) amended sediment (25 kg) at 9 tons/ha. Shrimps average weight 5 ± 0.03 g were stocked juveniles/m 3 fed satiation levels using commercially available feed. Compared control, biochar contained...
Natural and anthropogenic causes have led to soil degradation, salinisation of inland areas, groundwater. The degraded soils are unsuitable for primary agriculture, but can be utilised saline aquaculture. ICAR-CIFE has initiated a selective breeding program faster growth in common carp cultured at low salinity (6–8 ppt). present study demonstrates the dynamic nature physico-chemical parameters Inland Saline Ground Water (ISGW) potential selectively bred F1 generation using ISGW. About 1560...
A 60-day feeding trial was carried out to determine the effect of dietary lipid levels on growth and physiometabolic responses optimize requirement for maximizing Genetically Improved FarmedTilapia (GIFT) juveniles reared in inland ground saline water (IGSW) medium salinity (15 ppt). Formulation preparation seven heterocaloric (389.56-449.02 Kcal digestible energy/100 g), heterolipidic (40-160 g/kg), isonitrogenous (410 g/kg crude protein) purified diets were done conducting trial. Random...
A feeding trial was conducted for 90 days to assess the metabolic and digestive enzyme activity in response alternate or mixed of different protein levels diet Pangasianodon hypophthalmus fingerlings. One hundred forty four fingerlings with an average weight 5.0–5.5 g were distributed into experimental groups each triplicate. Four iso-caloric diets varying level crude viz., 35%, 30%, 25% 20% made designated as 35P, 30P, 25P 20P respectively. treatments maintained based on schedules such...
A yellowish brown bacterium was isolated from photoheterotrophic enrichment cultures obtained a mud sample collected mangrove forest located in Khola, India. Enrichment and isolation medium containing 2 % NaCl (w/v) yielded strain JA297T, cells of which were ovoid motile. Cells JA297T contained vesicular internal membranes bacteriochlorophyll carotenoids the spheroidene series. Strain grew optimally at 30 °C pH 6.0–7.0. Photo-organoheterotrophy preferred mode growth. also able to grow...
In aquaculture system, 40-60% cost comes from the production of fish regarding feed. Hence, there is a need in future to further reduce feed and its utilization with low input for growth high survival fish. Concerning former most obvious approach reducing decrease amount expensive ingredient i.e. fishmeal, through substitution suitable low-cost alternative ingredients, while ensuring that such will not compromise quality cultured stock. Previously, few attempts have been made on mixed...
Like other helminth proteases, filarial proteases have also been shown to require for parasite survival inside the host and mediate various physiologic processes such as tissue invasion, feeding, embryogenesis immune evasion. Many of these potential vaccines chemotherapeutic agents against active infections. Setaria cervi is a bovine serves good model studies in lymphatic filariasis. Recently, 175 kDa collagenase leucine aminopeptidase (LAP) purified characterized from S. be vaccine...
