Penaeus vannamei (the shrimp) is an omnivorous species and it can be assumed that a high level of carbohydrates is necessary for its growth. α-1,4- and 1,6-glucosidases are important enzymes necessary for the ultimate liberation of glucose residues from various carbohydrates, principally starch. However, the shrimp's hepatopancreas produces only α-1,4-glucosidases, which limits the growth rate in different sources of starch. In order to identify strains with α-1,4- and 1,6-glucosidase enzymes with potential uses in shrimp feed production, Bacillus strains were isolated from marine environments. One strain produced large amounts of an extracellular thermostable α-glucosidase that permitted good growth on starch. The organism was identified by polymorphism (restriction-fragment-length polymorphism, RFLP), sequenced, and named B. subtilis LMM-12. [ABSTRACT FROM AUTHOR] |
