The influence of a wide range of CO2 levels on the growth, morphogenesis, and secondary metabolite production in vitro was evaluated. Shoots of thyme (Thymus vulgaris L.) and a spearmint–peppermint cross (Mentha spicata × Mentha piperita) were grown on MS medium with and without 3% sucrose under 350, 1500, 3000, 10,000, and 30,000 μL CO2/L for 8 weeks. Dichloromethane extracts from leafs were analyzed using GC-MS techniques. Prominent peaks were identified by comparison with known standards. Highest growth (i.e., fresh weight) and morphogenesis responses (i.e., leafs, shoots and roots) were obtained when shoots were grown under 10,000 μL CO2/L regardless of whether or not sucrose was included in the medium. Ultra-high CO2 concentrations (3000 μL CO2/L) stimulated secondary metabolite production regardless of whether or not the medium contained sucrose. However, the combination of certain ultra-high CO2 levels (e.g., 3000 to 10,000 μL CO2/L) and the presence of sucrose in the medium resulted in shoots producing the highest levels of secondary metabolites. These results suggest that in vitro photosynthesis, which is stimulated by ultrahigh CO2 levels, may enhance secondary metabolite production.

Metabolite Production

Plant secondary metabolites are a group of organic compounds produced by plants to interact with biotic and abiotic factors and for the establishment of defence mechanism. Secondary metabolites are classified based on their biosynthetic origin and chemical structure. They have been used as pharmaceutical, agrochemical, flavours, fragrances, colours and food additives. Secondary metabolites are traditionally produced from the native grown or field grown plants. However, this conventional approach has some disadvantages such as low yield, instability of secondary metabolite contents of the plants due to geographical, seasonal and environmental variations, need for land and heavy labour to grow plants. Therefore, plant cell and organ cultures have emerged as an alternative to plant growing under field conditions for secondary metabolite production. In this literature review, present state of secondary metabolite production through plant cell and organ cultures, its problems as well as solutions of the problems were discussed.
