Isolation of seaweed-associated bacteria and their morphogenesis-inducing capability in axenic cultures of the green alga Ulva fasciata

Isolation and characterization of exopolysaccharides from seaweed associated bacteria Bacillus licheniformis

“…Similar findings have been demonstrated with Bacillus licheniformis which influence the life history and developmental morphology of Ulva fasciata (Singh, Mantri, Reddy, & Jha, 2011) in corresponding to increase the zoospore production and in attaining the normal foliose morphology. Further, seaweed-bacteria interactions are partly attributed to the extracellular substances secreted by associated marine bacteria.…”

Phytohormones in red seaweeds: a technical review of methods for analysis and a consideration of genomic data

“…To demonstrate that phytohormones can be supplied to red seaweeds through seawater, axenic cultures of algae are essential. However, such cultures of macroalgae are not available, apart from a few exceptions (Fries 1975, Singh et al 2011b, Spoerner et al 2012, Grueneberg et al 2016. At least two pathways of IAA biosynthesis are suggested in bacteria (Patten and Glick 2002).…”

Large-scale seaweed cultivation diverges water and sediment microbial communities in the coast of Nan'ao Island, South China Sea

“…In addition, seaweed-associated bacterial communities can produce quorum sensing molecules (Singh et al, 2015;Twigg et al, 2014), bioactive compounds (Singh et al, 2011a) and plant growth regulators (e.g. IAA, Cytokinin) (Maruyama et al, 1990;Yokoya et al, 2013) to guarantee normal morphology (Singh et al, 2011b), and development and growth of their host seaweed (Singh and Reddy, 2014). More importantly, a core set of specific bacterial community members, which may not exhibit phylogenetically similarities among different host seaweeds, seem to exist on the seaweed surface and contain similar functions related to host-associated lifestyles (Burke et al, 2011a;Burke et al, 2011b;Campbell et al, 2015;Hollants et al, 2013a).…”
