Current study is based on the larvicidal effect of mycosynthesized siver nanopartices (AgNPs) from Trichoderma ongibrachiatum (Tl-AgNPs) and viride (Tv-AgNPs) Aedes aegypti albopictus dengue vectors non-targeted aquatic crustacean, Moina macrocopa. Mosquito larvae were exposed to each test concentration (10 50 mg L-1) Tl-AgNPs Tv-AgNPs separately with three replicates containing 25 each. The AgNPs characterization confirmed formation in UV-Vis spectrum surface plasmon resonance (SPR) band at...
Three chitosan concentrations (1%, 3%, 5% w/v) were tested for their root growth promotion properties in air-layering of three popular ornamental Ficus species namely triangularis, microcarpa and benjamina. Subsequently, these treatment responses compared with a rooting hormone (naphthalic acetic acid) an organic promoting extract (Root Most) available the local market. Tap water was used as control. Air-layered plants further subjected to export simulation 14 days at 12-14°C 90% relative...
The lichen host, Amandinea medusulina, collected from mangrove habitats in Sri Lanka, and its associated endolichenic fungi were isolated identified by rDNA-ITS sequence analysis morphological features. One of the fungal strains frequently thalli was as Xylaria psidii. This study aimed at isolation identification cytotoxic compounds present this fungus. Secondary metabolites X. psidii first extracted into ethyl acetate subsequently subjected to bioassay-guided fractionation isolate bioactive...
This study aimed to examine the potentiality of microencapsulated cinnamon leaf oil (CNO-CS-MCs) and lemongrass (LGO-CS-MCs) as natural fungicides against Aspergillus flavus. Oil encapsulated microcapsules were synthesized using ionotropic gelation method. Cinnamon (CNO) (LGO) characterized GC-MS. A. flavus was isolated identified DNA sequencing. The minimum inhibitory lethal doses oil-loaded evaluated under in vivo conditions results further confirmed by silico analysis. major constituents...

Essential oils have long been attracted as substitutes for synthetic chemical pesticides because of their antimicrobial properties, low mammalian toxicity and wide public acceptance.Essential lemongrass cinnamon leaf were encapsulated using chitosan, a biodegradable polymer by emulsion formation/ionotropic gelation technique.A. flavus was isolated from stored rice.In-vitro antifungal efficacy oil loaded microcapsules against A. its time profile determined.Based on morphological molecular...
Nutritional compounds in yams may leach out to the cooking water under most traditional domestic methods.Finding alternative uses of these waste waters without discarding, can maximize usage and importance yams.This study aimed quantify bioactive determine antioxidant activity collected after boiling Dioscorea alata L. tubers two methods.Raja ala were boiled using conventional (CB) pressure (PC) methods.The both methods concentrated obtain solid crude product.Aqueous solutions product CB PC...
This study aimed to determine the DPPH free radical scavenging activity, total phenolic content (TPC) and flavonoid (TFC) of methanolic extract Durio zibethinus Murr. (durian) peels its fractions. The chemical constituents durian extracted into methanol by soxhlet extraction were sequentially hexane, dichloromethane aqueous methanol. Among fractions, fraction showed highest activity (IC50 179.9 ± 6.6 μg/ml) with high TPC TFC (85.82 12.11 mg gallic acid equivalent/g dried weight 12.66 1.94...
This work reports the synthesis of silver nanoparticles (AgNPs) using leaf extract Annona glabra as a green synthetic route and assessment its photocatalytic property methelyne blue model dye toxic effect against an aquatic model, Daphnia magna. Leaf prepared at 100 ºC, 1% plant extract, 1 mM AgNO3, 3 h incubation time were optimized for AgNPs. Surface plasmon resonance peak AgNPs laid around 419 nm. Spherical in size ranges 50-80 110-195 Biomolecules present capping agents on have cubic...
Ionotropic gelation using sodium tripolyphosphate (STPP) as the crosslinker was successfully used to formulate lemongrass oil containing chitosan microcapsules. Formation of in aqueous polymer solution followed by crosslinking with STPP. Optimum formulation for synthesis microcapsules found varying amounts (1-3 g), (1-2%) and STPP (0.5-1.0 g). Microcapsules were characterized Fourier transform infrared spectroscopy, scanning electron microscopy stage microscope. Encapsulation efficiency,...
Lasiodiplodia theobromae is one of the frequently isolated fast growing endolichenic fungus. This fungus was from lichen host, Pyrenula bahiana collected mangrove ecosystems in Puttlam lagoon and its identification confirmed based on rDNA-ITS sequence homology. Secondary metabolites L. were extracted into ethyl acetate subjected to antibacterial assay against Escherichia coli (ATCC25922), Staphylococcus aureus (ATCC25923) Bacillus subtilis (ATCC6051). Crude extract at a concentration 6.8...
