| dc.description.abstract | Pyrolysis products (aqueous phase of bio-oil, bio-oil and biochar) of sugarcane leaves, wheat straw, rice husk and pine needles were used for wheat seeds germination. Biochemical analysis of wheat seeds grown in presence of 2 mg/ml wheat biochar showed increased GA3 (86.58%), _-amylase (249%), reducing sugar (23%) and total dehydrogenase activities (149%). While there was a decrease in _-amylase activity (23%) and starch (30%) during first 20 hours of imbibition of seeds. Bioinformatic analysis of GC-MS data of biochar extract, revealed that the beta-sitosterol had lower _G value with karrikins receptor of Arabidopsis. GC-MS analysis of pine needles bio-oil showed approximately 50% phenols. These phenols were extracted by liquid-liquid extraction method with 86.52% yield. Antioxidant assay of extracted phenolic compounds showed high DPPH, Total antioxidant and reducing power activity. MTT assay of the aqueous phase of pine needle bio-oil was found lowest IC50 value for E.coli. Pine needles bio-oil was used for resin formation to replace phenol to synthesize the bio-oil- phenol-formaldehyde (BPF) resins. FTIR analysis showed that 30% BPF resins could have wood adhesive activity. Insecticidal properties of the aqueous phase of bio-oil and pure bio-oil against the third instar larvae of H. armigera and anti-ovipositional activity against the adult H. armigera was screened and found that the H. armigera was tolerant against all types of the aqueous phase of bio-oil and pure bio-oil. Ovipositional activity maximum decreased by pine needles bio-oil (52%). While more number of eggs were laid on wheat straw bio-oil (57%) showed attractant nature like pheromones. Catalytic esterification of sugarcane leaves bio-oil with n-propanol produce 61.5% yield with calorific values increased by 11.06% making fuel more suitable to be used in engines. | en_US |
