Correct option is (d) Bacillus Licheniformis
The best I can explain: The Association of Microbial Food Enzyme Producers (AMFEP) has suggested subdivisions of the FACC’s group B into 3 groups. Bacillus Licheniformis belong to Class bin8 microorganisms which are accepted as harmless contaminants present in food. Bacillus subtilis, Aspergillus Niger, and Mucor Javanicus belong to Class ain8 microorganisms that have organisms which are traditionally been used in food or in food processing. Other belonging to this category are Aspergillus Oryzae, Rhizopus Oryzae, Saccharomyces cerevisiae, Kluyveromyces fragilis, Kluyveromyces lactis etc.
