Dependence of biomass concentration, total sugar concentration and microbial transglutaminase activity on the fermentation time of Streptoverticillium ladakanum NRRL 3191 grown on molasses at different agitation speeds
Source publication
Transglutaminase is an enzyme that catalyses an acyl transfer reaction between g-car-boxamide groups of glutaminyl residues and lysine residues in proteins. Due to this property , this enzyme is used for enhancing textural properties of protein-rich food. The trans-glutaminase used as food additive is obtained by microorganisms, mainly by Streptove...

... highest biomass concentration of (8.39±0.61) g/L ( Fig. 1) was obtained after 72 h at 400 rpm. The increase of agitation speed enhanced the biomass production. This can be due to the fact that an increase in agitation speed increases the oxygenation of the culture media. Dissolved oxygen is one of the main factors that affect microbial growth and the formation of transglutaminase by S. ...

... fructose and saccharose concentrations were given as total sugar concentration, as shown in Fig. 1. The initial total sugar concentrations were 57.62, 56.15 and 48.13 g/L for fermentations at 200, 300 and 400 rpm, respectively. The initial concentration of glucose was 8.91 g/L at 200 rpm, which increased to 11.68 g/L in 24 h and then decreased to 0.4 g/L in 72 h. This behaviour showed that the decomposition of saccharose generated ...
