M

etagenomics provides

a culture-independent

assessment and gives

an insight into complex

relationships between

microbial composition

and functional diversity in

soil. Landfill and compost

sites provide unique

habitat to study microbial

interrelationships since they

host a great microbial diversity.

We report the taxonomic and

functional characterization of

the microbiome of composite

soil sample isolated from

typical landfill and compost

in Okhla, New Delhi, India.

Whole metagenome

sequencing was performed

to identify the microbial

community of the composite

soil sample using the Illumina

NextSeq500 platform.

Prodigal was performed

for the gene prediction

and resulting genes were

considered for downstream

analysis. The taxonomical

analysis was carried out using

Kaiju. The high-quality reads

were assembled using CLC

genomics workbench. Analysis

showed that

Methylocaldum,

Thalasobacillus, Acinetobacter

were the most dominant

genera where-as

Proteobacteria, Acinetobacter,

Firmicutes were the most

dominant phyla in Landfill.

Likewise, Streptomyces,

Saccharomonospora,

Nocardiopsis the most

dominant genera

whereas Actinobacteria,

Proteobacteria, Firmicutes

were the most dominant phyla

in compost. This suggests

the key role these microbes

play in biomass degradation.

The structure of microbiota

in the landfill was affected by

physicochemical properties

like pH, EC, organic matter

and moisture content and

presence of various elements.

Physicochemical analysis of

various elements was done

with ED-XRF. Our results

provide applicable analysis and

visualization approaches for

studying the complexity and

heterogeneity of soil microbial

communities. For functional

analysis COG, KEGG pathways

and GO was performed using

Cognizer. The COG class

‘R’ was found to have the

highest number of hits for

the composite sample. This

showed that most of the genes

were involved in “Metabolism”

of carbohydrates, amino acids,

energy, nucleotides and lipids,

xenobiotics biodegradation.

In our study, a significant

decrease in

Candidatus

Saccharibacteria

was observed

in the presence of

P. Indica

, a

plant endomycorrhiza. Further

investigations are in process to
