amyloliquefaciens group, all having a total number of CAZymes ranging between 115 and 145 (Table 1). A lower total number of CAZymes was found in the other spore-forming species considered in this study (Table 1). Among the analyzed species, thermophilic strains of Geobacillus and Alicyclobacillus and the facultative alkaliphile strain of B. pseudofirmus showed a total number of CAZymes significantly lower Dinaciclib mouse than the other Bacilli (Table 1). A comparison of the five CAZyme classes mostly confirmed the results obtained analyzing the total number of CAZymes. In particular, like strains of the B. subtilis/B. amyloliquefaciens group, B. indicus and B. firmus showed a high number of glycoside hydrolases (GH) and carbohydrate binding modules (CBM) and average numbers of glycosyl selleck screening library Transferases Epacadostat purchase (GT), polysaccharide lyases (PL) and carbohydrate esterases (CE) (Table 1).

This analysis showed that in comparison with the other Bacilli considered in this study, B. indicus and B. firmus have a high number of CAZymes of the GH13, GT2 and GT4 families and have some CAZymes of families not common in other Bacilli (GH2, GH16, GH31, GH35, GH36, GH66, GH84, GH94, GT5, GT27, GT32, CBM4, CBM13, CBM20, CBM41 and CBM56) (Additional File 3). In addition, we observed the presence in GB1 and HU36 of candidate enzymes for the potential degradation of animal glycans.
