Adsorption, immobilization and activity of cellulase in soil: the impacts of maize straw and its humification

Abstract: The present work aimed to study some aspects of sorption and immobilization of cellulase molecules on soil components by the analysis of the reactions of cellulase in a soil treated with different levels of maize residue and incubated for 90 days. The analysis of variance showed that the effects of the treatments of maize straw, incubation time and their interaction on cellulase adsorption, desorption and immobilization were statistically significant. The adsorption and immobilization capacities of soil by app… Show more

“…On the other hand, the decrease in polyphenol oxidase and peroxidase activities in T3 samples could be attributed to the specific microbial group that was not flourished well in the soil system although further planned study is required to explore the proper reason. Similarly, it was reported that soil organic carbon levels is associated with changes in cellulase activities 33 and thus marginal decrease in soil cellulase activities in T3 could be linked with the reduction in organic carbon contents after treatment by Cyperus brevifolius. The increase in total population of nitrogen fixing, phosphate and potassium solubilizing bacteria has showed the conformity with earlier works 5,34 where it was reported that 6.11-11 folds increase in beneficial microbial population is possible in the contaminated soil after phytoremediation trials.…”

“…Цей фермент досить добре вивчений, але інтерес до нього не пропадає тому, що саме цьому ферменту і мікроорганізмам, що його синтезують відводиться головна роль у кругообігу вуглецю, а саме виділенню у атмосферу CO 2 . Тому целюлозоруйнуюча активність вивчається різними методами у різних ґрунтах і за різних умов [1][2][3][4][5][6]. Оскільки целюлаза безпосередньо впливає на швидкість розкладу рослинних решток, а целюлоза є домінуючим компонентом рослинних решток і органічних добрив, вивчення активності цього ензиму є першочерговою задачею при вивченні біологічної активності ґрунтів, а сам показник є чудовим біоіндикатором загального стану агроценозів [7,8].…”
