Explanation: 

Detailed explanation-1: -Penicillium roqueforti is used as a fungal starter culture for the production of a number of blue-veined cheeses, with both proteolytic and lipolytic enzymes produced by the fungus involved in cheese ripening and flavor production.

Detailed explanation-2: -Penicillium roqueforti is a common saprophytic fungus, that is widespread in nature and can be isolated from soil, decaying organic substances and plant parts. The major industrial uses of this fungus are for the production of blue cheeses, flavoring agents, antibacterials, polysaccharides, proteases and other enzymes.

Detailed explanation-3: -Penicillium roqueforti is a common saprotrophic fungus. The major industrial use of this fungus is the production of blue cheese, flavouring agents, antifungals, polysaccharides, proteases and other enzymes. The fungus has been a constituent of roquefort, stilton, Danish blue, cabrales and other blue cheese.

Detailed explanation-4: -A related fungus, Penicillium roqueforti, is the key microbe in blue cheese (Figure 1B).
