“…Varieties of chemical mechanisms take place in soil that ensure the sustainability of invisible life and create an ideal ecosystem for them. Soil is the most common niche for bacteria, actinomycetes, fungi, protozoa, and algae which contribute in the maintenance of diversified natural processes such as enhancement of plants’ growth, decaying of organic substances, nitrogen fixation, and production of secondary metabolites ( Al-Dhabi et al, 2018a , Al-Dhabi et al, 2019a , Imadi et al, 2016 ). Among diverse soil microflora, bacteria are the predominant prokaryotes with high physiological and metabolic variations ( Archana et al, 2015 ).…”

Soil is an integral part of ecosystem which is niche for varieties of microflora. The present study was investigated to isolate varied strains of bacteria from soil samples of three different geographical regions of Tamil Nadu (India) and evaluate their hydrolytic enzymes (amylase, cellulase, and inulinase) producing potentialities. Among 72 bacterial cultures isolated from Ambattur Industrial Estate, Neyveli Lignite Corporation, and Arignar Anna Zoological Park regions, 41.66, 38.88, and 36.11% of isolates were observed amylase, cellulase, and inulinase producers, respectively. On the other hand, 20.83% of total bacteria isolated from all three regions exhibited concurrent production of amylase, cellulase, and inulinase. Potent isolates depicting maximum enzyme activities were identified as Bacillus anthracis strain ALA1, Bacillus cereus strain ALA3, Glutamicibacter arilaitensis strain ALA4, and Bacillus thuringiensis strain ALA5 based on molecular characterization tools. Further, the thermodynamics parameters, open reading frames (ORFs) regions, and guanine-cytosine (GC) content were determined by distinct bioinformatics tools using 16S rRNA sequences of strains. Minimum free energy values for strain ALA1, strain ALA3, strain ALA4, and strain ALA5 were calculated as −480.73, − 478.76, −496.63, and −479.03 kcal/mol, respectively. Mountain plot and entropy predicted the hierarchical representation of RNA secondary structure. The GC content of sequence for strain ALA1, strain ALA3, strain ALA4, and strain ALA5 was calculated as 53.06, 52.94, 56.78, and 53.06%, respectively. Nine ORFs were obtained for strain ALA1, strain ALA3, and strain ALA5 while 10 ORFs were observed for strain ALA4. Additionally, bootstrap tree demonstrated close resemblance of strains with existing bacteria of similar genus. Findings showed higher variability of bacterial diversity as hydrolytic enzymes producers in the investigated geographical regions.

“…Soil bacteria play imperative role not only in sustaining cleaner ecosystem and building the fertility of soil but also maintain bio-geochemical cycles ( Imadi et al, 2016 ). Most importantly, bacteria autochthonous to soil are vast producers of enzymes.…”
