Effect Of Light

In this research, the effect of solar irradiance on Chlorella vulgaris cultivated in open bioreactors under greenhouse conditions was investigated, as well as of ratio of light intensity in the 420–520 nm range to light in the 580–680 nm range (I420–520/I580–680) and of artificial irradiation provided by red and white LED lamps in a closed flat plate laboratory bioreactor on the growth rate and composition. The increase in solar irradiance led to faster growth rates (μexp) of C. vulgaris under both environmental conditions studied in the greenhouse (in June up to 0.33 d−1 and in September up to 0.29 d−1) and higher lipid content in microalgal biomass (in June up to 25.6% and in September up to 24.7%). In the experiments conducted in the closed bioreactor, as the ratio I420–520/I580–680 increased, the specific growth rate and the biomass, protein and lipid productivities increased as well. Additionally, the increase in light intensity with red and white LED lamps resulted in faster growth rates (the μexp increased up to 0.36 d−1) and higher lipid content (up to 22.2%), while the protein, fiber, ash and moisture content remained relatively constant. Overall, the trend in biomass, lipid, and protein productivities as a function of light intensity was similar in the two systems (greenhouse and bioreactor).

Different types of bio-polysaccharide play a vital role in the growth of PLBs cultured in vitro. In this study, to we investigated the potential impacts of two bio-polymers,: hyaluronic acid (HA9) and sodium alginate (ALG) on the organogenesis of protocorm-like bodies (PLBs) in Phalaenopsis under white LED lights. PLBs of Phalaenopsis ‘Fmk02010’ were explanted on modified MS medium with different concentrations of HA and (ALG). The highest average number of PLBs per explant (24.6) was recorded for ALG alone at a concentration of 0.01mg/L, and the fresh weight was also highest at the same concentration. The combination of 0.01mg/L ALG and 0.01mg/L HA also resulted in a large number of PLBs (23.8) and high fresh weight. As opposed to, the highest number of shoots /explant (3.6) was observed at the treatment of the combination of 1mg/L ALG and 10mg/L HA. This study shows that the application of ALG and HA alone, and in combination, at low concentrations, increased the average number of PLBs and the amount of fresh weight, but shoot formation was higher at a high concentration compared with control.

Background and Aim: Manipulating lighting colors and regimens is considered an effective mean for improving broiler productivity. The influence of red, blue, and white light-emitting diode (LED) was investigated using three different regimens of lighting and darkness; continuous 23 h light (L):1 h dark (D), continuous 18 h L:6 h D, and intermittent 16 h L:8 h D hours on the performance, carcass weight (CW), feed and water intake (WI), serum glucose (GLUCO), triglycerides (TG), and cholesterol (TC), intestinal bacterial load, growth and metabolic hormones, and efficiency of Newcastle disease (ND) vaccine. Materials and Methods: A total of 252 1-day-old Ross broilers on deep litter were divided into nine groups. The 1st, 4th, and 7th groups were exposed to continuous 23L:1D, the 2nd, 5th, and 8th groups were exposed to continuous 18L:6D, and the 3rd, 6th, and 9th groups were exposed to intermittent 16L:8D (4L:2D, 4 times) lighting regimen using red, blue, and white LED lights, respectively. A total of 1350 samples (225 sera, 225 swabs, and 900 organ samples) were collected. Results: Blue LED group revealed a highly significant increase (p<0.01) in live body weight, body weight gain, performance index, CW, spleen, heart, and liver weights, and anti-ND antibody titer, as well as a highly significant decline (p<0.01) of feed intake, WI, GLUCO, TG, TC, growth hormone, insulin, tri-iodothyronine (T3), tetra-iodothyronine (T4), total bacterial count (TBC), and total Enterobacteriaceae count compared to red and white LED lights in all tested lighting regimens. Continuous 23L:1D and 18L:6D regimens were significantly (p<0.01) superior to intermittent 16L:8D in their influence on the performance, CW, biochemistry, hormonal profile, and bacterial load. Conclusion: The blue LED light associated with continuous 18L:6D or 23L:1D h regimen is highly recommended in broiler houses for their enhancing the productive performance, growth, and immunity.
