Answer 2

Explanation:

3.Mesophilic spoilage can occur due to underprocessing (Table 9.3). Insufficient heat treatment results in the survival of mesophilic Clostridium and Bacillus spores. They can germinate and grow to cause spoilage after processing. The predominant spoilage bacteria in canned foods are mesophilic spore-forming bacteria.

4.Tobacco mosaic virus (TMV) is a positive-sense single-stranded RNA virus species in the genus Tobamovirus that infects a wide range of plants, especially tobacco and other members of the family Solanaceae.

5.The microbe which forms cottony mass on a moist bread slice is a very common fungus, the Bread Mold Fungus Rhizopus stolonifer.
