“…A small amount of astaxanthin is produced before the initial fermentation time (0-36h) after which there is an increment in the astaxanthin content. Yang et al (2011) demonstrated the same parameter when producing astaxanthin with P. rhodozyma and showed that maximum production was after 36h of fermentation.…”

“…Agro-industrial wastes provide the carbon and nitrogen sources and other elements needed to carry out microbial metabolism (Mata-Gómez et al, 2014). Cassava (Manihot esculenta) residues, like cassava wastewater (manipueira), contain a small amounts of starch, protein, cellulose and other nutrients (Nitschke and Pastore, 2004;Choubert et al, 2005;Kaewpintong et al, 2006;Vasconcellos et al, 2009;Casullo et al, 2010;Yang et al, 2011;Yimyoo et al, 2011, Saoudi andFei, 2012). The liquid waste from industrial cassava processing contains a large number of pollutants and has a significant adverse environmental impact.…”

Astaxanthin is a xanthophyll, a very common red-colored pigment of marine organisms that are in increasing demand in the market because of their applications in the food, cosmetics, and pharmaceutical industries. Particularly, astaxanthin has been found to play protective roles against many chronic human diseases, and diseases associated with oxidative stresses caused by excess free radicals and other reactive oxygen species. Mucor circinelloides f. circinelloides is able to accumulate astaxanthin by stress conditions. The aim of this study was to produce astaxanthin by M. circinelloides f. circinelloides cultivated in the presence of exogenous stress conditions using a natural medium of cassava wastewater (CWW), continuous illumination with blue LED and fluorescent lamps in a bioreactor for 96 hours. The best condition for astaxanthin was under a fluorescent lamp (150 µg/g per dry biomass). The carotenoid fraction was extracted using acetone, followed by separation and purification by thin-layer chromatography. The astaxanthin was identified and quantified using spectrophotometry, based on the absorption coefficients. The antioxidant activity was evaluated using (2,2-Diphenyl-1-picrylhydrazyl) DPPH, and a higher antioxidant effect was observed by fluorescent lamp. This is one of the first reports on antioxidant activity in astaxanthin produced by Mucor circinelloides and the biotechnological potential for this fungus was demonstrated.

“…These studies indicate that β-carotene offers protection against metal-induced lipid oxidation (Darko, 2011). In the present study, the No.BY1109 had the same ability as Rhodotorula to produce pigment and carotenoid (Yang et al, 2011), and the pigment became deep red when the content of iron (Fe II) increased in medium. A possible explanation is based on observations that presence of heavy metals results in the formation of various active oxygen radicals which, in turn, induces the formation of protective carotenoid metabolites that reduce negative behavior of free radicals (Darko, 2011).…”

Iron is an essential element for nearly all living organisms, and its deficiency is the most common form of malnutrition in the world. The organic forms of trace elements are considered more bioavailable than the inorganic forms. Although Saccharomyces cerevisiae can enrich metal elements and convert inorganic iron to organic species, its tolerability and transforming capacity are limited. The aim of this study was to screen higher biomass and other iron-enriched fungi strains besides Saccharomyces cerevisiae from the natural environment. A PDA medium containing 800 μg/mL iron was used for initial screening. Fifty strains that tolerated high iron concentration were isolated from the natural environment, and only one strain, No.BY1109, grew well at Fe (II) concentration of 10,000μg/ml. According to morphological characterization, 18S rDNA sequence analysis, and biophysical and biochemical characterization, the strain No.BY1109 was identified as Rhodotorula. The iron content of No.BY1109 (10 mg Fe/g dry cell) was determined using atomic absorption spectrometry. The results of distribution of iron in the cells showed that iron ion was mainly chelated in the cell walls and vacuoles. The bioavailability in rats confirmed that strain No.BY1109 had higher absorption efficiency than that of ferrous sulfate after single dose oral administration. The present study introduces new iron supplements, and it is a basis for finding new iron supplements from natural environment.Keywords: iron-rich fungus; screening and isolation; identification; cell-iron distribution; bioavailability.Practical Application: Iron is an essential element for nearly all living organisms, and its deficiency is the most common form of malnutrition in the world. The present study described the higher bioavailability of iron from natural environment grown in high iron medium. The result is interesting and shows some new data for finding new iron supplements from natural environment.

“…Astaksantin adalah xantofil merah (oksigen karotenoid) dengan manfaat diaplikasikan dalam akuakultur, farmasi, dan industri makanan (Rodriquez et al, 2010). Menurut Yang et al (2011) astaksantin adalah pikmen karotenoid dengan rantai molekul (3,3-dihidroksi -b, β-karoten -4, 4-dion) yang ditemukan di seluruh hewan, terutama di spesies laut seperti di lobster, kepiting, udang, ikan trout, serta salmon. Astaksantin dapat ditemukan pada mikroalga (Haematococcus pluvialis), udang, ganggang, ragi, ikan sunu merah, salmon (Moretti et al, 2006).…”

Indonesian water area is vast and has a great potential of natural resources. Most of the Indonesian people working as fisherman describes that oceanis place of making a living. Watery area resources Indonesian watery area is vast and has a great potential incude shrimps, fish, and other organism tosupport human life. Ocean organism has been known to contain nutrition which is good for humanâ€™s health. Shrimps contains omega 3, mineral, fat,citin, carotenoide (astaxanthin) and vitamin. The active compound have an ability to prevent disease and meet the nutritional need of body. Omega3 andastaxantin for example are active compounds found in shrimps. These compound play a role as antioxidant and free radicals scavenger can be supplementfor pregnant women and baby. Omega 3 and antaksantine are found in various shrimps and fish. Thus, the development of product from this organismincludes supplement, margarine, cake, souse, bread, kerupuk, flour and salt. In this review, the writer describes the the functional compound and itsusage as food product.
