Five of the discovered GHs share more than 90% sequence identity with enzymes from Bifidobacterium species, which were already shown to be involved in prebiotic breakdown: one

Indeed, geometrical approaches for flamelet regime usually assume that the filtered flame thickness and chemical profiles are not affected by sub-filter scale flame wrinkling..

During a cycle, the mean area S T of these instantaneous area measurements is approximately equal to the area of the reference laminar flame S 0 (the difference is less than

However, it creates a feedback loop in 1D premixed flames when Z is computed locally, where the wrong value of Z , Z u used to access the table leads to inconsistent values of the
