“…Similar to the feedback interactions between plant and rhizosphere microorganisms Qu et al, 2020 ), there are complex interactions between phycosphere microorganisms and algae ( Amin et al, 2015 ). The most popular connection between bacteria and algae is the exchange of substances.…”

Freshwater cyanobacterial blooms have drawn public attention because they threaten the safety of water resources and human health worldwide. Heavy cyanobacterial blooms outbreak in Lake Taihu in summer annually and vanish in other months. To find out the factors impacting the cyanobacterial blooms, the present study measured the physicochemical parameters of water and investigated the composition of microbial community using the 16S rRNA gene and internal transcribed spacer amplicon sequencing in the months with or without bloom. The most interesting finding is that two major cyanobacteria, Planktothrix and Microcystis , dramatically alternated during a cyanobacterial bloom in 2016, which is less mentioned in previous studies. When the temperature of the water began increasing in July, Planktothrix appeared first and showed as a superior competitor for M. aeruginosa in NO 3 − -rich conditions. Microcystis became the dominant genus when the water temperature increased further in August. Laboratory experiments confirmed the influence of temperature and the total dissolved nitrogen (TDN) form on the growth of Planktothrix and Microcystis in a co-culture system. Besides, species interactions between cyanobacteria and non-cyanobacterial microorganisms, especially the prokaryotes, also played a key role in the alteration of Planktothrix and Microcystis . The present study exhibited the alteration of two dominant cyanobacteria in the different bloom periods caused by the temperature, TDN forms as well as the species interactions. These results helped the better understanding of cyanobacterial blooms and the factors which contribute to them.

“…Streptomyces form siderophores that promote Azadirachta indica plant growth by increasing the availability of the required amount of iron. And the fourth way, in which microbes facilitate plant growth is to protect the plants from various pathogens by acting as a biocontrol agent, root colonizers, and environmental protectors (Qu et al 2020). PGPR competes with pathogens for the limited nutrient available in the rhizosphere and rhizoplane by Fig.2 Social, economical, and environmental challenges in the agricultural sector reducing the contact surface between pathogen and plant roots or by interfering with the mechanisms leading to plant disease (Jayaprakashvel et al 2019).…”

Beneficial microbes in soil biota are known to enhance plant growth by stimulating the nutrient supply and by devising certain mechanisms to cope up with the biotic (diseases) or abiotic (salinity, drought, and pollution) stresses. Owing to their effectiveness and sustainability concerns, the application of microbes in the agricultural sector has seen a positive surge recently. Biochar has been commended as an exemplary carrier material for beneficial microbes in the soil ecosystem. Biochar is generally produced from the waste biomasses, which not only resolve the management crisis of agricultural wastes but also render many benefits such as enhancement of soil properties, alteration of nutritional dynamics, removal of pollutants, and in the stimulation of beneficial microbial diversity in soil. The strategic application of biochar in agricultural land could help provide agronomic, economic, and environmental benefits. Since certain risks are associated with the application of biochar, attention needs to be paid while preferring for soil amendments. This present review focused on highlighting the role of microbes in plant growth. The influence of biochar on soil biota along with its detailed mechanisms was discussed further to delineate the scope of biochar in soil amendments. Further, the risks associated with the biochar amendments and the future perspectives in this research arena were highlighted.

“…Simplified synthetic microbial communities are being considered as comprehensible systems for uncovering an in-depth view of community assembly principles. These systems are able to circumvent the complexity of natural ecosystems and allow the capture of community behaviors [17] , [18] , [19] , [20] , [21] . One approach is to reduce the complexity of natural communities by selection of microbial consortia under laboratory conditions from environmental samples [22] .…”
