Abstract :

Lignin is a by product from Kraft and sulphite pulping industry. It is a complex biopolymer obtained after cellulose fie extraction from plants. Effective treatment of this lignin is essential for reducing the pollution of water bodies. In the present study, the alkalophilic NaOH effluent from an industry was nullified using acid, HCL, treatment. The effluent wastreated with fresh strains of, Bacillus subtilis and Trichoderma spp. The efficiency and quality of strains confirmed using plate count. The fertilizer incubated for 14 days and applied to Vigna unguiculataseeds. Biometric evaluations were performed and the yield has found to be increased compared to control and absolute control. This potential treatment of chemical slurry can be compensated for lignite and peat base of phosphate solubilizers, potassium and nitrogen fixers. The GC–MS analysis of the formulated fertilizer detected the presence of components like dineopentylesters which stimulate its biocontrol activity. Plant growth promoting factors like macro nutrients and micro nutrients confirmed by total Kjeldahl digests, UV–Visible Spectrophotometry and Flame Photometer.
