“…This would help to maximize the productivity and quality of Oncidesa plantlets cultured in vitro . In addition, CCFLs have several advantages over existing lighting systems used for plant tissue culture ( Tanaka et al 2009 ). In particular, CCFLs emit much less heat through their unique properties, allowing plants or cultures (culture vessels) to be placed very close to the light source, making more efficient use of the culture room and intensifying the efficiency of CO 2 enrichment.…”

“…Light is also an essential factor for plant growth and development. Recently, the use of cold cathode fluorescent lamps (CCFLs) as a radiation source for plants has been attempted because of their attractive features, including their small diameter (1.6–3.0 mm), long life (50 000 h) and low heat generation, with an estimated 40 % reduction in electric energy consumption used for lighting and air conditioners during micropropagation ( Tanaka et al 2009 ; Norikane and Tanaka 2010 ). Those studies demonstrated that Cymbidium and Phalaenopsis in vitro plantlets cultured under CCFLs showed enhanced photoautotrophic growth compared with plantlets cultured under conventional heat fluorescent lamps.…”

How can one increase the biomass of plants, particularly orchids, in an effective way? Photoautotrophic micropropagation is an effective means of increasing the biomass of Oncidesa orchids. Using 10,000 µmol mol−1 CO2 and a photosynthetic photon flux density of 60 µmol m−2 s−1, the number of leaves and roots and shoot and root fresh and dry weights could be considerably increased, but only when cultured on Kyoto medium rather than Vacin and Went medium. Super-elevated CO2 enrichment and growth under cold cathode fluorescent lamps can positively affect the efficiency and quality of commercial production of clonal Oncidesa plantlets.

“…CCFLs have been widely used in diverse fields, such as car navigation system displays, notebook computers, PDAs, liquid crystal monitors, and widescreen LCD TVs [23]. Recently, a CCFL was applied to plant cultivation to make use of advantageous attributes such as low heat emission, low energy consumption, long service life, small diameter, and uniform light intensity [23][24][25]. C. vulgaris FSP-E were grown in conventional and modified PBRs.…”

Fish meal is currently the major protein source for commercial aquaculture feed. Due to its unstable supply and increasing price, fish meal is becoming more expensive and its availability is expected to face significant challenges in the near future. Therefore, feasible alternatives to fish meal are urgently required. Microalgae have been recognized as the most promising candidates to replace fish meal because the protein composition of microalgae is similar to fish meal and the supply of microalgae-based proteins is sustainable. In this study, an indigenous microalga (Chlorella vulgaris FSP-E) with high protein content was selected, and its feasibility as an aquaculture protein source was explored. An innovative photobioreactor (PBR) utilizing cold cathode fluorescent lamps as an internal light source was designed to cultivate the FSP-E strain for protein production. This PBR could achieve a maximum biomass and protein productivity of 699 and 365 mg/L/day, respectively, under an optimum urea and iron concentration of 12.4 mM and 90 μM, respectively. In addition, amino acid analysis of the microalgal protein showed that up to 70% of the proteins in this microalgal strain consist of indispensable amino acids. Thus, C. vulgaris FSP-E appears to be a viable alternative protein source for the aquaculture industry.

“…In our study, the PPFD of LP and WPT-LP system was maintained at 45 μmol m In order to improve space usage efficiency in culture room, Hayashi et al (1992) developed a sideward lighting system using fluorescent lamps. However, when using this lighting system, space was needed to install the lamp and to have the distance between culture vessels and the light source because the fluorescent lamps emitted heat (Chen, 2005;Tanaka et al, 2009). The fluorescent lamps are placed 30-50 cm above the vessels in order to avoid temperature increase inside the vessels in the conventional downward lighting system (Kitaya et al, 1995).…”

-Wireless power transmission has been recently used to charge batteries in portable devices. This is the first study to combine this technology with light-emitting diodes (WPT-LP) for plant tissue culture application. We also present the comparison of the in vitro growth of chrysanthemum and strawberry plantlets under the new LED lighting system; LED -Uni-Pack (LP) system; LED tube and fluorescent light (FL). The results showed that fresh weight (1.42 g), dry weight (118.67 mg), plant height (5.68 cm), leaf area (3.59 cm 2 ) and chlorophyll content (47.9 μg g -1 ) of chrysanthemum plantlets under the WPT-LP system were higher than those under FL and LED tube. Similar results were also recorded on the strawberry plantlets. Our results suggested that utilizing WPT-LP system saves the culture space considerably compared with the conventional downward lighting system with fluorescent lamps. The results also indicated that the subsequent growth and development of chrysanthemum and strawberry plantlets derived from WPT-LP system were either equal to or better than those from LP system under LED tube or FL.Keywords: chrysanthemum, development, growth, LEDs, photosynthetic photon flux density, wireless power transfer. RESUMO -A transmissão de energia sem fio tem sido usada recentemente para carregar baterias em dispositivos portáteis. Este estudo é o primeiro a combinar essa tecnologia com diodos emissores de luz (WPT-LP) para aplicação em cultura de tecido vegetal. Também são apresentadas comparações entre crescimento in vitro de plântulas de crisântemo e morango com o novo sistema de iluminação: sistema LED -Uni-Pack (LP), tubo LED e luz fluorescente (FL
