TL;DR: Solid-state fermentation provided 48% more polygalacturonase activity compared to submerged fermentation under individually optimized conditions.

TL;DR: β-Galactosidases produced by pure and mixed cultures of Streptococcus thermophilus 95/2 and Lactobacillus delbrueckii ssp bulgaricus 77 (Lb 77) isolated from the Toros mountain region of Turkey were characterised with respect to their biochemical and thermal properties and could be considered as potential candidates for lactose hydrolysis of milk and milk products.

TL;DR: In this study, in vitro and in vivo analyses have been used to clarify the roles of individual SleB and YpeB domains in PG degradation and support the role of this invariant glutamate as the key catalytic residue insleB and CwlJ.

TL;DR: In this paper, the associative growth of Streptococcus thermophilus 95/2 and Lactobacillus delbrueckii ssp. bulgaricus 77 (Lb 77) isolated from the Toros mountain region of Turkey was investigated with respect to lactic acid, biomass and β-galactosidase enzyme production using response surface methodology (RSM).

TL;DR: Data indicate that while the presence of either the N- or C-terminal domain of B. megaterium SleB is sufficient for initiation of cortex hydrolysis and the generation of anhydromuropeptides, the perceived lytic transglycosylase activity may be derived from an enzyme(s), perhaps exclusively or in addition to SleB, which has yet to be identified.
