Enhancing the process of its biological degradation using microbial strains capable of decomposing lignocellulose would not only solve the problem of CR disposal but also recycle the organic carbon, NPK and other plant nutrients back into the soil. This study was aimed at isolating and screening of the lignocellulose decomposing microbes from various sources such as crop residue incorporated soil, forest soil, soil near decaying wood, compost pit and dump yard. Total of 15 fungi and 6 bacteria were isolated in the form of pure colonies and screened for cellulose and lignin decomposing ability using carboxymethylcellulose (CMC) and tannic acid (TA) agar media on the basis of appearance of clear zone. Five fungal and two bacterial cultures identified as lignocellulose decomposers were further screened quantitatively for CMCase and filter paperase enzyme assay by standard protocols. Two fungal strains, identified as Trichoderma species and Aspergillus species showed significant enzymatic activity and can be utilized as a potential lignocellulose decomposer.","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"128 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88130520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this, soil samples (0-15 cm depth) were collected from five treatments viz. control, 100% NP (NP), 100%NPK (NPK), 100% NPK+FYM (NPKF) and 100% NPK + lime (NPKL) from long-term fertilizer experiment (LTFE), Birsa Agricultural University, Ranchi (since 1971) at pod formation stage of soybean crop (2018).Resistance and resilience capacity of soil SIR being analyzed at 1 and 30 days after heat stress (DAS). Results revealed that, SIR was significantly affected by long-term fertilization and heat stress. Balanced fertilization along with lime application (NPKL) had significantly higher SIR rate (10.78 mg CO2 g/soil/ h) followed NPKF, NPK, control and NP treatments. After 1 DAS, the SIR increased at 24 hour of substrate addition. However, during the 24-48 hours, the SIR value decreased significantly and maximum reduction was noticed under control treatments (47%). Cumulative SIR decreased significantly after heat stress, maximum reduction being in NPKL and NPKF treatments, whereas minimum under control. NPKF = NPKL treatments recorded highest resistance (0.86) followed by NP (0.82) > NPK (0.79) > control (0.61).Resilience index of NPKL (0.52) and NPKF (0.50) were highest and superior over other treatments. In nutshell, SIR emerged as a good indicator to asses’resistance, resilience capacity of soil against heat stress.","PeriodicalId":8031,"journal":{"name":"Annals of Plant and Soil Research","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74116426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
