Water ecosystems in form lakes in diverse regions provide indispensable water resources for humans. The microbiomes in lake ecosystems are a suitable bioresources for agriculture, industry and allied sector. The microbiomes from lake ecosystems may be isolated using different nutrient combination and specific media for different groups of bacteria. There are many reports on microbial community of lake ecosystem and it was found microbes has been identified from different phylum including Actinobacteria, Cyanobacteria, Acidobacteria, Caldeserica, Calditrichaeota, Verrucomicrobia, Chlorobi, Planctomycetes, Nitrospirae, Chloroflexi, Bacteriodetes, Firmicutes and Proteobacteria. Microbes are ubiquitous in nature, inhabiting almost every habitat including soil, water, air and associated with plants. The microbes are present in extreme environmental conditions like hot springs,1‒4 saline environments,5,6 cold environments,7‒10 acidic/alkaline soil,11,12 drought13‒15 and plant associated.16‒20 Microbes play central roles in regulating elemental cycles like carbon, nitrogen, and sulfur. Lake is an area which is filled with water and surrounded by land. It is localized in a basin, apart from any river or other outlet that serves to feed or drain the lake. Microbiome varies among lakes with different environmental variables.

The microbiome in the freshwater lake ecosystems have been investigated worldwide e.g. Toolik Lake, Alaska, USA,21 Adirondack lake, New York,22Lake Loosdrecht, The Netherlands,23 Crystal Bog Lake and Sparkling Lake, USA,24 Lake Cadagno, Switzerland,25 Lake Fuchskuhle, Germany,26 Crater Lake, USA,27 Lake Soyang, South Korea,28 Lake Biwa, Japan,29 Lake Washington,30 Lake Kasumigaura, Japan,31 Lake Tanganyika, Africa,32 Lake Taihu, China,33 Lake Puma Yumco,34 Roopkund Lake, India,35 Vembanad Lake, India,36 Dianchi Lake, China,37 Lake Erie, USA,38 Laurentian Great Lakes,39 Chandra Tal Lake, India,9 Dashair Lake, India,9 Lake Baikal, Russia,40 Claytor Lake, USA,41 and Lake Baikal, Russia.42

The microbes are ubiquitous in nature and also have been reported as niches or host-specific from all habitat study e.g. from cold habitats,7,43‒45 from thermal springs,1-3 from saline habitats,5,46 from drought,47‒49 from soil12,15,18 and as plant microbiomes.13,16,19,20,50‒53 The niche-specific microbes from freshwater lakes have been reported e.g. Zoogloea from Toolik Lake, Alaska, USA; Legionella and Prevotella from Adirondack lake, New York; Planktothrix from Lake Loosdrecht, The Netherlands; Amoebobacter, Desulfocapsa, and Lamprocystis from Lake Cadagno, Switzerland; Haliscomenobacter and Spirosoma from Lake Gossenkollesee, Austria; Bdellovibrio, Eikenella, Polaromonas, and Rathayibacter from Crater Lake, USA; Caenibacterium, Hymenobacter, Methylocystis, Novosphingobium, Paucimonas and Propionivibrio from Lake Kasumigaura, Japan; Aminnobacter, Gelidibacter, Kaistella, Mesorhizobium, Methylocapsa, Niastella, Rhizobium and Tetrasphaera from Lake Taihu, China; Plantibacter from Chandra Tal Lake, India; Massilia and Nitrosomonas from Dianchi Lake, China; Brevibacillus, Hafinia, and Klebsiella from Manasbal Lake, India; Sanguibacter from Roopkund Lake, India on review of 27 freshwater lake ecosystems present in worldwide.

A huge number of novel bacteria belonging to various classes and families have been reported from freshwater lake ecosystem worldwide e.g. Ferribacterium limneticum, CdA-1 Coeur d’Alene Lake,54 Hymenobacter aquatilis, HMF3095T Artificial lake,55 Sphingobium fontiphilum, Chen16-4T Chengcing Lake,56 Limnobacter thiooxidans, CS-K1 Chiemsee Lake,57 Desulfovibrio idahonensis, CY1T Coeur d'Alene,58 Thiobaca trueperi, Eutrophic lake,59 Listeria marthii, FSL S4-120T Finger Lakes60 Sphingomonas hengshuiensis, WHSC-8T Hengshui Lake,61 Kinneretia asaccharophila, KIN192T Kinneret Lake,62 Algoriphagus aquatilis A8-7T Longhu Lake,63 Limnohabitans curvus, MWH-C5T Mondsee Lake,64 Cloacibacterium rupense, R2A-16T Rupa Lake,65 Undibacterium seohonense, SHS5-24T Seoho lake,66 Polynucleobacter difficilis, AM-8B5T Sevan Lake,67 Flavobacterium chuncheonense Soyang Lake,68 Flavobacterium soyangense, IMCC26223T Soyang Lake,69 Flavobacterium luteum IMCC26026T, Soyang Lake,68 Mucilaginibacter soyangensis, HME6664T Soyang Lake,70 Flavobacterium lacicola, IMCC25901T Soyang lake,71 Flavobacterium saliperosum, S13T, Taihu Lake,72 Roseomonas lacus TH-G33T Taihu Lake,73 Rhodoluna lacicola, MWH-Ta8T Taihu Lake,74 Nocardioides taihuensis, X17T Taihu Lake,75 Lysobacter oligotrophicus, 107-E2T Tanago Ike,76 and Nocardioides ungokensis, UKS-03T Ungok Lake.77


Microbial community play a central role in global environmental processes and earth biogeochemistry, with bacteria being the most important component of microbial community responsible, in aquatic ecosystems, for the organic matter mineralization and nutrient recycling processes. Microbiome represents the richest gamut of molecular and chemical diversity in nature, as they comprise the simplest yet dynamic forms of life. Future studies might focus on analysing the more bacterial community from diverse lakes ecosystem in different environmental conditions of salinity, pH, temperatures, osmotic potential and pressure in order to decipher the potential role in nutrients cycling of the microbial community present which is largely unexplored reservoir of resources for innovative applications useful to mankind.
