Cellulose effects on morphology and elasticity of Vibrio fischeri biofilms

Bacteriology: Cellulose production by bacteria affects their growth patterns Different strains of the same bacterium show different sessile growth characteristics according to the amount of cellulose they produce. A team at Israel’s Ben-Gurion University of the Negev, headed by Moshe Herzberg, exami...

A team at Israel’s Ben-Gurion University of the Negev, headed by Moshe Herzberg, examined the growth of three strains of Vibrio fischeri (a bacterium found globally in marine environments) that produce different amounts of cellulose.
