“…As an alternative to synthetic pigments, bacterial pigments due to their better biodegradability and higher compatibility with the environment offer promising avenues for various applications. The industry is now able to produce some bacterial pigments for applications in food, pharmaceuticals, cosmetics, and textiles (Venil et al 2013).…”

Marine bacteria produce natural pigments; however, the ability of marine bacterial symbionts to produce natural pigments has been less studied. Marine bacteria associated with soft-coral Sarcophyton sp. collected from Karimunjawa Island were successfully isolated and screened to synthesize the carotenoid pigments. This approach has allowed the use of these symbionts as an environmental friendly source of new natural pigments. Out of 33 bacterial isolates, only 4 bacterial symbionts (CBSCP 2-2, CBSCP 2-3, CBSCP 1-1, and CBSCP 2-4), positively contain carotenoid pigments. Molecular identification based on 16S rDNA method showed that bacterial symbionts CBSCP 2-2, CBSCP 2-3, CBSCP 1-1, and CBSCP 2-4 were closely related to Pseudoalteromonas shioyasakiensis, Pseudoalteromonas rubra, Virgibacillus salaries, and Pseudoalteromonas spongiae. Pigment analysis showed that the pigments have been categorized within the groups of carotenoid pigments. Antioxidant activity of pigment extracts was done by measuring inhibitory concentration (IC 50 ) of pigment extract against 2,2-diphenyl-1-picrylhydrazyl (DPPH) solution. The antioxidant activity measurement of CBSCP 1-1, CBSCP 2-2, CBSCP 2-3, and CBSCP 2-4 extract, and b-carotene was 2015, 5017, 2520, 4213, and 1980 mg l -1 , respectively.

“…The wide variety of food colorants currently applied in food industry has been highly scrutinized, both from regulatory agencies and subsequent updated legislation as also scientific researchers, that exert a meticulous and increasingly detailed study of food colorants, including a wide variety of evaluation criteria (Konczak et al, 2005;Shahid et al, 2013;Venil, Zakaria, & Ahmad, 2013). World consumers also perform a significant interference in these aspects, because they are increasingly informed and more exigent in relation to the quality, safety, credibility and scientific assurance of commercialized foodstuffs and their chemical additives, even requesting "clean labels" (Carocho et al, 2014(Carocho et al, , 2015Gengatharan et al, 2015).…”

Background: Worldwide consumers seek most delightful and appealing foodstuffs, at the same time they require safer, more nutritious and healthier products. Color is one of the most important organoleptic attributes that directly affects consumers' acceptance and food selection. Scope and approach:The present report aims to provide an extensive approach to the field of food (natural/synthetic) colorants, namely those who are currently allowed with established acceptable daily intake (ADI). It also describes the biotechnological and industrial techniques that have been used to optimize food attractiveness, shelf life and color stability, as well as the general trends and future perspectives of food science and technology in the topic of food colorants. Key findings and conclusions:Synthetic food colorants were largely used, but have been progressively substituted by those obtained from natural origins. Numerous side effects and toxicity, at both medium and long-terms, allergic reactions, behavioral and neurocognitive effects have been related with their use. Otherwise, naturally-derived food colorants seem to provide high quality, efficiency and organoleptic properties, and also play a contributive role as health promoters. Anthocyanins, carotenoids, phenolic compounds, beet derivatives, annatto and some curcuminoids are among the most commonly used, while strict regulatory practices have been applied looking for food quality assurance.

“…On the other hand, metabolites produced in microbial cell factories such as small Fig. 4 Two approaches to creating synthetic microbes: (1) creating life de novo, creating an artificial cell at least needs to integrate three main components: containment, cellular processes, and information and (2) bioengineering approach, using a refined version of genetic engineering, designing, and inserting elements inside the cells to perform specialized functions molecule (e.g., ethanol [89], lactic acid [90,91], glycerol [92]), antibiotic [93] (e.g., penicillin), pigment [94], protein [95] and glycoprotein [96], polysaccharide (e.g., hyaluronic acid [97], bacterial cellulose [98]), and even virus-like particles (as vaccine) [99] have been widely used in the production and life of human beings (Fig. 6).…”

Microbes are important part of life that vary in sizes and shapes, diverse surface chemistry and biology, and porous nature of their cell walls. Besides their importance in industrial processes such as fermentation, these serve as biotemplates and provide a biomimetic approach for fabrication of multifarious complex constructs with predefined features, ordered composites and hybrid nanomaterials, microdevices, and micro/nanorobots through various strategies. The template or building blocks for such approaches can be bacterial, algal, and fungal cells or virus particles. Here, we have summarized recent advancements in biofabrication based on live microbes. Using engineering approaches and suitable methods, live microbes can be manipulated as functional Bmicro/nanodevices and -robots^to further perform biological functions such as replication, distribution, motility, formation of colonies, and secretion of metabolites at will. Biofabrication based on microbes provides effective methods to control and manipulate microbes as functional live building blocks to create micro/nanodevices and -robots for biomedical and energy applications.
