Microbial Community Dynamics Nutrient Recycling By Xenobiotics Degradation

The rate of glacier retreat has increased dramatically as a result of climate change. The ice has melted, exposing bare spots that can become new ecosystem development sites [1]. Here, primary microbial succession starts to build up organic material in preparation for plant colonisation. The Chhota Shigri glacier is one such glacier that has receded significantly and offers a perfect location for investigations of microbial succession [2]. Here, we looked at how the microbial communities and their functional characteristics changed as the glacier forefield transitioned from an exposed glacier snout to a fully-developed forested foreland [3]. Sequencing methods for metagenomes include amplicon sequencing [4]. Patescibacteria, Gemmatimonadota, Proteobacteria, Bacteroidota, and other microbial phyla were prevalent in the forefield locations closer to the glacier snout. These organisms have the capacity to cycle carbon and sulphur: Chloroflexi, Cyanobacteria, Verrucomicrobiota, and Myxococcota [5]. The heterotrophic taxa Actinobacteria and Acidobacteriota, which aid in the recycling of organic material, were prevalent at the places further from the glacier snout [6]. In comparison to locations farther from the glacier terminal, those closer to it had a greater variety and richness of microorganisms [7]. The whole-genome metagenome investigation also indicated the predominance of genes related to N, C, and cycle [8]. The local soil temperature was the main factor affecting the quantity and diversity of the microorganisms, followed by pH and element concentration. The bacteria and genes responsible for the breakdown of the xenobiotic chemicals Aminobenzoate, Benzoate, and Caprolactam have also been found in the soils of the forefield [9]. This study highlighted microbial successional gradients, which are caused by local environmental conditions [10].
