“…The additional blue light was less stressful than the red light [45]. Katsuda et al [46] reported that red LED light allowed the growth of the green alga Haematococcus pluvialis, whereas blue LED light enhanced astaxanthin production. More recently, Katsuda et al [47] showed that in mixotrophic growing conditions, flashing LED light (8 mmol photon m 22 s 21 ) triggered similar astaxanthin concentration to continuous LED light (12 mmol photon m 22 s 21 ).…”

Providing an adequate quantity and quality of food for the escalating human population under changing climatic conditions is currently a great challenge. In outdoor cultures, sunlight provides energy (through photosynthesis) for photosynthetic organisms. They also use light quality to sense and respond to their environment. To increase the production capacity, controlled growing systems using artificial lighting have been taken into consideration. Recent development of light-emitting diode (LED) technologies presents an enormous potential for improving plant growth and making systems more sustainable. This review uses selected examples to show how LED can mimic natural light to ensure the growth and development of photosynthetic organisms, and how changes in intensity and wavelength can manipulate the plant metabolism with the aim to produce functionalized foods.

“…Similarly, Enterobacter aerogenes W-23 bacteria was exposed to He-Ne laser irradiation to improve the hydrogen production ability [26]. Katsuda et al found LED emitting light of short wavelengths (380-470 nm) induced astaxanthin accumulation of up to 5-6% per dry-cell, although it caused the suppression of cell growth [33]. Kuwahara et al reported that red and blue laser diodes were applied in growing the green algae Chlamydomonas reinhardtii to determine the effectiveness of laser diodes as an electric light source for algae production [34].…”

Abstract:The impacts of laser radiation (Nd: YAG laser, 1064 nm at 800 mW, He-Ne laser 808 nm at 6 W, semiconductor laser 632.8 nm at 40 mW) on growth and lipid accumulation of Chlorella pacifica were investigated in this study. The results showed growth rates increased 1.23, 1.41, and 1.40-fold over controls by 4 min Nd: YAG, 4 min He-Ne, and 8 min semiconductor laser treatments, respectively, whereas the corresponding nitrate reductase observed increased 1.25, 1.63, and 2.08-fold over controls. Moreover, total chlorophyll concentration was increased to 1.09, 1.29, and 1.33-fold over controls, respectively. After 20 days cultivation, the highest lipid content was 35.99%, 18.46%, and 31.00% after 2 min Nd: YAG, 4 min He-Ne, and 4 min semiconductor laser treatments, corresponding to 2.86, 1.50, and 2.46-fold increase over controls, respectively. Furthermore, the lipid productivity of the above 3 treatments were 15.25 ± 2.56, 16.25 ± 2.45, and 14.75 ± 2.11 mg L −1 d −1 . However, the highest lipid productivity was 22.00 ± 3.28, 16.25 ± 2.45, and 19.25 ± 1.78 mg L −1 d −1 , in response to treatment for 2 min Nd: YAG, 1 min He-Ne, and 4 min semiconductor laser treatments, with 2.67, 1.97, and 2.33-fold increase over controls, respectively. These results indicated that lipid accumulation efficiency of C. pacifica could be significantly improved by laser irradiation using Nd: YAG, He-Ne, and semiconductor laser treatments.

“…Golkhoo et al (2007) produced astaxanthin with Phaffia rhodozyma (wild type and mutant forms) cultivated in a rich medium of YMB (yeast malt broth): 140 µg/g (wild type) and 230 µg/g of astaxanthin (mutant). This demonstrated that M. circinelloides is a promising source of astaxanthin.…”

“…Astaxanthin has also been exploited for industrial use, principally as an agent for pigmenting cultured fish and shellfish (Gross and Lockwood 2004;Kim et al, 2006;Park et al, 2010;Romero et al, 2010). A DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay is routinely conducted to assess its potential for free radical scavenging of an antioxidant molecule which is considered to be one of the standard and easiest colorimetric methods for evaluating the antioxidant properties of pure compounds (Hsu et al, 2005;Cheng et al, 2006;Noipa et al, 2011;Tai et al, 2012).…”

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.
