Efficient Plant Growth-Promoting (PGP) Native -Formulated Consortia Mode and Assessed Shelf Life Using Low-Cost Dynamic Media.

Various isolates were collected from the microbial germplasm, including KAC3 (PP550146), KAC4 (PP177363), KAC6 (PP177364), KAC8 (PP177365), KAC10 (PP177366), KAC11(PP177366), and KAC12 (PP177389). Three consortia formulations were then selected based on their compatibility with plant growth-promoting rhizobacteria (PGPR) properties under laboratory conditions: C consortium (KAC3, KAC10 and KAC11), C (KAC4, KAC8 and KAC10), and C (KAC11 and KAC12). In this study, we explored the use of locally available, cost-effective carrier materials, such as wood ash (NPK ratio: 1.

Impact of anthropogenic input on physicochemical parameters and trace metals in marine surface sediments of Bay of Bengal off Chennai, India.

The study of heavy metal distribution in coastal surface sediments is an important component in understanding the exogenic cycling as well as in assessing the effect of anthropogenic influences on the marine ecosystem. In this study, surface sediment samples were collected from five different traverses along the innershelf of Bay of Bengal, off Chennai, India during pre- and post-monsoon seasons. The results of Spearmen correlation matrix, factor and cluster analysis, enrichment and contamination factor analysis, and geoaccumulation index of the heavy metals analyzed in the collected surface sediment were discussed.
