The genus Bacillus is a phenotypically large, heterogeneous collection of Gram-positive or Gram-variable spore-forming, aerobic or facultative anaerobic bacteria that have undergone considerable reclassification following the advances in molecular biology techniques [ 1, 2 ].

The large polysaccharide molecule starch contains two parts, amylose and amylopectin, these are rapidly hydrolyzed using a hydrolase called alpha-amylase to produce smaller molecules: dextrins, maltose, and glucose. Reaction: To test for the presence of alpha amylase, a starch hydrolysis test can be performed.

Considering the difficulties in the identification of Bacillus species and the poor microbiological quality of many probiotic formulations, we used three up-to-date methodological approaches for analyzing the content of ten formulations marketed in Italy and labeled to contain Bacillus spores.
Biochemical tests for characterization of bacteria
A system is described for the rapid and accurate identification of Bacillus isolates using a matrix of results from tests in the API 20E and API 5OCHB strips and from supplementary tests. API System tests have been shown to be more reproducible than the classical tests. A taxonomy based upon API tests is in good agreement with those obtained by other methods. The results matrix can also be.

The versatile physiology of Bacillus spp. requires biochemical tests for their identification [9]. 16S rRNA gene sequence analysis has proved to be of evident for phylogenetic analysis of bacteria [10]. Bacillus species may be divided into five or six groups (groups I-VI), based on 16S

In this study, we evaluated qualitative and quantitative aspects of ten probiotic formulations marketed in Italy and containing Bacillus spores. We compared the performance of MALDI--TOF MS (Bruker Daltonics, Bremen, Germany) and biochemical tests based on the Vitek2

Biochemical testing is necessary to identify the organism up to the species level. Following biochemical characteristics help to identify B. cereus from other species of Bacillus. Inability to produce acid from mannitol. Production of lecithinase. Bacillus cereus is usually motile by peritrichous flagella. A few B. cereus strains are non-motile.

The Bacillus especially Bacillus subtilis and Bacillus licheniformis are excellent candidates for large-scale production of commercially important enzymes [11].. On the basis of morphology, physiology and biochemical tests, the selected strain was identified as B. licheniformis. It showed oxidase and catalase activities and was able to.
Bacillus Biochemical Test
Biochemical characterization is routinely used to distinguish between closely related Bacillus species. Some of the biochemical tests which are mostly given positive by most of the Bt strain includes utilization of carbohydrates, Voges-Proskauer test, nitrate reduction test, citrate utilization test, hydrolysis of starch and casein, liquefaction of gelatin, decomposition of tyrosine.
