“…IPP/DMAPP has multiple destinations: (1) to farnesyl diphosphate (FPP) by FPP synthase (FPPS)-this can be used for the synthesis of sesquiterpenes (e.g., humulene, artemisinic acid, artemisinin) and triterpenes (e.g., dogfish, olefin, oleanolic acid, aromatic acid); (2) to form geranyl diphosphate (GPP) by GPP synthase (GPPS), which can serve as the precursor to monoterpenes (e.g., limonene, menthol); and (3) to GGPP, which can be used for synthesizing diterpenes (e.g., sclareol, taxadiene, paclitaxel) beyond carotenoids. Nannochloropsis has the potential to synthesize these valuable terpenoids via metabolic engineering as long as the corresponding enzymes can be functionally expressed in the alga (Figure 2).…”

“…Biodiesel from plants, however, is a long way from meeting the existing demand and will cause the conflict of food versus fuel. Algae has gradually come to people's attention because of its advantages of fast growth, no competition with grain, and higher oil production potential than plants [1,2]. However, it remains economically infeasible for algae to serve as a separate biofuel producer.…”

In light of the escalating global energy crisis, microalgae have emerged as highly promising producers of biofuel and high-value products. Among these microalgae, Nannochloropsis has received significant attention due to its capacity to generate not only triacylglycerol (TAG) but also eicosapentaenoic acid (EPA) and valuable carotenoids. Recent advancements in genetic tools and the field of synthetic biology have revolutionized Nannochloropsis into a powerful biofactory. This comprehensive review provides an initial overview of the current state of cultivation and utilization of the Nannochloropsis genus. Subsequently, our review examines the metabolic pathways governing lipids and carotenoids, emphasizing strategies to enhance oil production and optimize carbon flux redirection toward target products. Additionally, we summarize the utilization of advanced genetic manipulation techniques in Nannochloropsis. Together, the insights presented in this review highlight the immense potential of Nannochloropsis as a valuable model for biofuels and synthetic biology. By effectively integrating genetic tools and metabolic engineering, the realization of this potential becomes increasingly feasible.

“…Due to their high productivity, rapid growth cycle, rich nutrient content and minimal need for arable land and freshwater resources, they are regarded as a promising food source to address the challenges posed by a growing population and environmental degradation. They possess the ability to accumulate various nutritional products such as lipids [5], proteins [6] and pigments [7], which have found extensive applications in industries related to food, nutraceuticals, healthcare and cosmetics [8,9].…”

Microalgae are recognized as a promising and valuable source of lutein. However, the current two-stage method for lutein production has drawbacks, such as complex operations and a long cultivation time. Additionally, utilizing heterotrophic fermentation to cultivate microalgae for lutein production leads to low lutein content due to the absence of light. In this study, we proposed a novel cultivation method that involves light induction of the seed culture to enhance lutein production during the heterotrophic cultivation phase of Chlorella protothecoides CS-41. To gain comprehensive insights into the underlying mechanisms of this method, we conducted qualitative and quantitative analyses of specific metabolites related to central carbon metabolism. The results revealed that low-light induction of seeds exhibited higher carbon efficiency compared to cells continuously subjected to heterotrophic cultivation, which may explain the observed increase in biomass and lutein content in cultures. Cultures after low-light induction of seed exhibited significantly higher lutein content (2.71 mg/g), yield (66.49 mg/L) and productivity (8.59 mg/L/d) compared to those consistently cultivated under heterotrophic conditions (2.37 mg/g, 37.45 mg/L, 4.68 mg/L/d). This cultivation strategy effectively enhances lutein yields, reduces production costs and holds the potential for broader application in other algal species for pigment production.

Expanding our food supply: underutilized resources and resilient processing technologies

Many underutilized food resources have been traditionally used by regional and poor communities. The history of their consumption makes them potential new food sources for incorporation into the wider food supply. The ability to tap the potential of undervalued and underutilized food sources will reduce the world's reliance on a limited number of food sources and improve food security and sustainability. The expansion of the food diversity of the food supply to include underutilized food resources will require overcoming challenges in the efficient and profitable production of the raw material, application of suitable postharvest handling procedures to maintain the quality of perishable produce, and the use of appropriate traditional and emerging food processing technologies for conversion of the raw material into safe, nutritious and consumer‐acceptable foods. Improvement of food processing technologies, particularly resource‐efficient resilient food processes, are required to ensure the safety, quality and functionality of the whole food or extracts, and to develop ingredient formulations containing new foods for manufacture of consumer food products. Factors that help facilitate the social acceptance of new underutilized foods include increasing consumer knowledge and understanding of the contribution of new underutilized food resources to diet diversity for good nutrition, confidence in the safety and value of new foods, and their low environmental impact and importance for future sustainable food. The introduction of new underutilized food resources will increasingly require collaboration along the whole food value chain, including support from government and industry. © 2024 The Author(s).
