Several of the substances in lab are everyday kitchen items. Would it have been useful to include soy sauce as one of the unknown substances for the assays?

Solution

Yes, it have been useful to include soy sauce as one of the unknown substances such as \"aflatoxin (fungal food toxin) assay\" of fungal species (Aspergillus fumigates species) because soy sauce is the nutritious food material obtained from Aspergillus sojae, & used to analyze the presence of \"aflatoxin\" of food fungi via fermentation assays inside the lab. Some tomes these soy sauces are food for these A. flavus species in lab cultures to analyze the presence of \"aflatoxin biosynthesis pathway genes\" finally results can be compared with the \"soya supplied with knock out gene for aflatoxin\".
