Explanation

Dunaliella salina (a halophilic green alga) produces glycerol as an osmoprotectant in response to salt stress. Corynebacterium glutamicum is the industrial workhorse for glutamic acid (MSG) production. Alcaligenes faecalis (now reclassified as Achromobacter faecalis) produces curdlan, a bacterial polysaccharide. Streptomyces nodosus produces amphotericin B (likely what 'Amphoterin' refers to, possibly a variant name or typo).
