Background: Myrciaria dubia “camu-camu” a fruit-bearing shrub native to the Amazon, is known for its high vitamin C content. However, variations in vitamin C biosynthesis and accumulation among different cultivars present challenges for commercial production. This study aimed to establish an efficient in vitro regeneration protocol for the Vitahuayo cultivar through callus induction and somatic embryogenesis. Methods: Stem and leaf explants were cultured on Murashige and Skoog (MS) medium supplemented with 24-dichlorophenoxyacetic acid (24-D) and 6-benzylaminopurine (BAP) to induce callus formation. Somatic embryos were induced using Woody Plant Medium (WPM) supplemented with 2,4-D, thidiazuron (TDZ), indole-3-butyric acid (IBA), naphthaleneacetic acid (NAA) and kinetin (KIN). Result: The best results for callogenesis were obtained with 1 mg/L of 24-D and 0.5 mg/L BAP. Somatic embryo...

A plausible strategy to mitigate socioeconomic problems in the Peruvian Amazon is through the sustainable exploitation of biodiversity resources, such as native microalgae. Several studies worldwide affirm that these microorganisms are excellent sources of higher value products for human nutrition and possess health-promoting biochemicals, but these attributes are unknown for the native microalgae of Peru. Therefore, the aim of this investigation was to evaluate the nutritional and human health-promoting potential of compounds biosynthesized by native microalgae from the Peruvian Amazon. Ten native microalgae strains of the groups cyanobacteria and chlorophyta were cultured in BG-11 medium and their biomass harvested and dried. Standardized methods were then used to determine proximate composition, fatty acids and amino acids composition, antioxidant activity, and total phenolic content....

The objective of this chapter is to provide scientific information on basic aspects to be taken into account to achieve the successful isolation, biochemical, and molecular characterization and then to evaluate the biotechnological potential of native microalgae of the Peruvian Amazon. Recent investigations reported by our research team has demonstrated that the isolated native microalgae from the Peruvian Amazon have a great potential for the biotechnological production of biodiesel and nutraceuticals. This biotechnological potential was identified thanks to the application of various protocols that were standardized by the authors over the last 5 years. In conclusion, the native microalgae of the Peruvian Amazon have biotechnological potential and are therefore promising for the production of both biodiesel and nutraceuticals. Various species of microalgae were identified, isolated, cu...
