“…Torularhodin is an uncommon carotenoid with potential applications ranging from food technology to pharmaceutics. This carotenoid exhibits strong antioxidant activity, acts as a vitamin A precursor, and has been proposed as a colorant for meat products due to its characteristic red color (Moliné, Libkind, & van Broock, 2012;Zoz, Carvalho, Soccol, Casagrande, & Cardoso, 2015). Recently, the anticancer potential of torularhodin has been demonstrated in vivo on mice (Du et al, 2016).…”

Microorganisms (bacteria, yeast, and microalgae) are a promising resource for products of high value such as nutrients, pigments, and enzymes. The majority of these compounds of interest remain inside the cell, thus making it necessary to extract and purify them before use. This review presents the challenges and opportunities in the production of these compounds, the microbial structure and the location of target compounds in the cells, the different procedures proposed for improving extraction of these compounds, and pulsed electric field (PEF)‐assisted extraction as alternative to these procedures. PEF is a nonthermal technology that produces a precise action on the cytoplasmic membrane improving the selective release of intracellular compounds while avoiding undesirable consequences of heating on the characteristics and purity of the extracts. PEF pretreatment with low energetic requirements allows for high extraction yields. However, PEF parameters should be tailored to each microbial cell, according to their structure, size, and other factors affecting efficiency. Furthermore, the recent discovery of the triggering effect of enzymatic activity during cell incubation after electroporation opens up the possibility of new implementations of PEF for the recovery of compounds that are bounded or assembled in structures. Similarly, PEF parameters and suspension storage conditions need to be optimized to reach the desired effect. PEF can be applied in continuous flow and is adaptable to industrial equipment, making it feasible for scale‐up to large processing capacities.

“…Zoz et al . () suggested the possible use of TRu and TRo as components of cosmetics and food. Studies of toxicity conducted on rats demonstrated that β‐carotene, TRo and TRu produced by R. glutinis yeasts can be used as innocuous food additives (Latha & Jeevaratanm, ).…”

Carotenoid profile produced by Bacillus licheniformis Rt4M10 isolated from grapevines grown in high altitude and their antioxidant activity

Summary Bacillus licheniformis (BL) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or inducing plant systemic resistance against stresses. However, investigations on the biological functions and applicability of carotenoids produced by BL had been less studied. In this study, the carotenoid profile produced by BL Rt4M10 was characterised during the accumulation period of culture and in response to diphenylamine (DPA), inhibitor of carotenoid biosynthesis. The antioxidant scavenging capacities of the carotenoid extracts against oxidative reactions inside the microbial cell and in vitro were also evaluated. Eighteen different carotenoids were analysed; their profile was modified along bacterial growth. DPA decreased carotenoid production by 70%, as well as the cells’ survival in hydrogen peroxide and the antioxidant capacity, thus demonstrating the role of carotenoids from Rt4M10 in oxidative stress.

“…The compositions of carotenoids are similar, consisting of β-carotene, γ-carotene, torulene and torularhodin. The torulene is the carotenoid of higher occurrence in yeasts (Zoz et al, 2015).…”

Carotenoids are natural pigments that can be synthesized by various microorganisms, including bacteria, yeasts, filamentous fungi and microalgae. These pigments comprise around 700 different structures with peculiar colors and biological properties that are beneficial to health. Advantages of biotechnological production of carotenoids include the ability of microorganisms to use low cost substrates, the optimized control of cultivation, minimized production time and the natural origin of the synthesized pigments. Techniques for separation and purification of carotenoids are well established at laboratory scale, however the development of processes that can be economically scaled-up is essential for industrial production.
