In a dense algal culture, the intensity of light is greatly reduced due to the scattering of light and absorption. The wavelength of the light source, culture density, penetration depth of light and the photobioreactor design play a huge role in reducing a certain light source . Although a white light source comprises a wide range of wavelengths, i.e., colors, microalgae mostly consume the Algal biofilm was periodically sampled and observed by scanning electron microscopy (SEM) (microscope JEOL 6300, JEOL Ltd.). For each sample, at least three fields were observed at different magnifications (×2500 to ×14000). Algal biofilms were also observed by an optical microscope at ×100, ×400, and ×1000 magnification. Results and the cells are submerged in a gel or scaffold that gives temporary support and al - lows the cells to merge and to connect to each other. By providing anchor points to the nascent tissue, the cells will align in between the anchor points and start to build up tension. This tension is the result of contractile proteins, but at the Most outdoor culture techniques result in low algal density, high contamination, problem in harvesting and lipid separation from the algal cells. The low algal cell productivity of mass scale techniques has prompted the development of enriched outdoor mass culture methods like raceway, photobioreactors and attached algal culture system (Fig. 1 ). If there is space and resources, as well as many microalgae in cultivation, it is appropriate to divide the species into culture environments with temperatures appropriate to each group: a room or incubator at 15°C, another at 20°C, and a third at 25°C, for example. The existing blue mussel culture has two technical limitations. The first is the unpredictability in seed supply. Techniques for seed supply are dredging wild seed beds, scraping mussel seed from rocks and collecting seed by natural settlement on, ropes or other substrates. Success of any of these methods depends on environmental conditions, But upon reviewing the current state-of-the-art for monitoring algal cultures, Havlik et al. note that the contamination monitoring techniques currently available (including optical microscopy, flow cytometry, and qPCR) are all offline methods. These require laboratory access and the participation of skilled support staff for routine operation. Moreover, these techniques are not extensible to The culture was mixed by sparging air through a sparger composed by nineteen needles uniformly spaced. The needles, with 0.25 mm of diameter (d n) and 20 mm length (L n), had 5.0 mm of distance between them. The shape and size of the needles ensure the formation of small and well-defined bubbles. Needles' placement enables a uniform bubble Fig. 1. The present invention relates to a gelidium amansis culture technique which belongs to the technical field of algae culture. The present invention is characterized in that gelidium amansis seeds are cut by a cutting machine, obtained cut sections whose length is from 0.3mm to 1.3mm are spread and sown on attached media, and the sections are cu
