The biological process of acidogenesis results in further breakdown of the remaining components by acidogenic ( fermentative ) bacteria.
22.
It is negative for the following tests : nitrate respiration, fermentative growth, catalase, and cytochrome oxidase.
23.
Also the fermentative yeast " Saccharomyces cerevisiae " was mostly absent from Hongqu starters but present in Xiaoqu.
24.
In addition, fermentative bacteria gain maximum energy yield when protons are used as electron acceptor with concurrent H 2 production.
25.
Some types of Xiaoqu are now prepared by mixing yeast sediment with the normal inoculum to produce a more fermentative starter.
26.
They are oxidative but not fermentative, and when isolated and cultured, their growth occurs on MacConkey agar and SS agar.
27.
Cellulosic sugars are used as renewable resources for biochemical and biofuels industries and can be used to produce intermediates by fermentative processes.
28.
After glucose is depleted, the fermentative product ethanol is oxidised in a noticeably slower second growth phase, if oxygen is available.
29.
The improvements of metabolic engineering by synthetic biology is an example of a biotechnological technique utilized in industry to discover pharmaceuticals and fermentative chemicals.
30.
Yeast species form part of the symbiotic nature of a Jiuqu starter and can be enzymatic ( substrate-degrading ) and / or fermentative.
