Purification and characterization of an intracellular family 3 β-glucosidase from Lactobacillus sanfranciscensis CB1
2005
Lactobacillus sanfranciscensis CB1 uses cellobiose and other β-glucosides (methyl-β-glucoside, arbutin, amygdalin and salicin) as carbon sources. A hexameric ca. 288 kDa β-glucosidase was purified to homogeneity from Lact. sanfranciscensis CB1 by four chromatographic steps. The enzyme was optimally active at pH 7.5 and 40°C. It had a pI of ca. 4.38 and a D55°C value of ca. 27 sec. Almost total inhibition was found with sulfhydryl-modifying agents and divalent cations such as Cu2+, Co2+, Hg2+, Ni2+ and Fe2+ at a concentration of 2 mM. The enzyme was active towards β-(1→4) substrates such as p-nitrophenyl-β-D-glucoside, -D-galactoside and -L-rhamnoside, and cellobiose. The sequencing of four …

L’utilizzo dei cereali per l’alimentazione umana risale all’era neolitica, come rivelato dalla scoperta di cariossidi fossili (Toderi 1989). Gli alimenti a base di cereali sono stati fondamentali per millenni e ancora costituiscono la principale fonte nutritiva per molte popolazioni (Blandino et alii 2003). I cereali contengono i macronutrienti necessari per la crescita e forniscono anche importanti minerali, vitamine e altri micronutrienti essenziali per il mantenimento di un buono stato di salute, sebbene siano carenti in alcuni componenti quali gli aminoacidi essenziali (ad es. lisina e triptofano). Il costante consumo di cereali riduce il rischio di malattie dovute a mala-alimentazione …

LACTOBACILLI IN SOURDOUGH FERMENTATION: A REVIEW
2007
Sourdough technology is widely used; it is employed in bread making and for the production of cakes. Sourdough is characterized by a complex microbial ecosystem, mainly represented by lactic acid bacteria and yeasts, whose fermentation confers to the resulting bread its characteristic features such as palatability and high sensory quality. Investigation of the microbial composition of sourdough is relevant in order to determine the potential activities of sourdough microorganisms. This review focuses on the role of the most important group of sourdough fermenting bacteria that consists of lactobacilli; species that belong to the Lactobacillus genus are the main responsible of flavor develop…
