Gellan gum is a kind of extra cellular polysaccharide excreted by microorganism pseudomonas
elodea. It is a linear structure with a repeating unit of tetrasaccharide.
The treatments were designed as follows; treatment 1 (T1) = without soil substrate and with feed supply with 40% of crude protein and 7.5% Ethereal Extract (Potimar 40J-Guabi[R]); treatment 2 (T2) = without soil substrate and without feed supply; treatment 3 (T3) = with soil substrate, feed supply and the addition of an aquatic macrophyte (
Elodea sp.); and, treatment 4 (T4) = with soil substrate, aquatic macrophytes and without feed supply.

Elodea nuttallii.

Elodea canadensis (G6, G7, G8, and G10), and Echinococcus felidis (3).
Submerged vegetation, like pondweed and
elodea, helps remove excess nutrients, resulting in clearer water.
For
Elodea canadensis, underground parts have been estimated at 2.6% of the total plant biomass, whereas underground parts were ~50% of the biomass of Littoiella uniflora and Potamogeton lucens (Westlake, 1966; Ozimek et al., 1976).
Hydrilla, Hydrilla verticillata (L.f.) Royle (Hydrocharitaceae), also commonly known as water thyme or Florida
elodea, is an extremely successful macrophyte that has invaded several continents worldwide and is considered a nuisance species (Evans & Wilkie 2010).

Gellan gum is an exocellular polysaccharide secreted from the bacterium Sphingomonas
elodea and consists of repeating tetrasaccharide of glucuronic acid, rhamnose, and glucose [26, 27].
According to Parent (1982),
Elodea canadensis may have been a vehicle for C.
