“…These fatty acids are omega 3 fatty acids, and there is linoleic acid which is 19.34% omega 6. When compared to the previous study (Ermavitalini et al, (2017), the linoleic and linolenic acids produced by B160 were 1.2 and 7-times higher respectively. At a high dose, B320 has several types of hydrocarbons.…”

“…Mutagenic engineering using gamma irradiation to Botryococcus sp. has been increased biomass and lipid production up to 1.5 times (Ermavitalini et al, 2017). A similar study showed that Arthrospira platensis that irradiated with high-dose electron beam may increase lipid accumulation by about 30 -34 times higher than the control (Kim et al, 2014).…”

“…has a lipid content with SFA and MUFA composition of up to 85.1% per dry weight and PUFA content of 14.90%. The microalgae with high composition of SFA and MUFA can be developed as a potential producer of lipids (Ermavitalini et al, 2017). High composition of SFA and MUFA in cell of organism can be recommended processed into biodiesel (Singh & Mallick, 2014).…”

Botryococcus sp. is an economically important microalgae as it contains carbohydrates, lipids, proteins, and a number of phytochemicals. The high concentrations of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) in this strain also a valuable source for production of biofuel. Mutagenic engineering using irradiation has been known to increase the content of these biomass. The aim of this study is to know the effect of electron-beam irradiation to the growth profile and fatty acid composition of Botryococcus sp. In this study, Botryococcus sp. adjusted an optical density 1.0 after being exposed to different doses of electron-beam irradiation (160 kGy, 240 kGy, and 320 kGy) and induced random mutagenesis for strain improvement was observed based on high energy (1.5 MeV and 2 mA). Several mutants obtained were designated as strain B160, B240, and B320, respectively. The profile growth was significantly different between control (0 kGy) and irradiated microalgae strain. The highest growth is found in B320 mutant. Fatty acid of Botryococcus sp. control produced 7 fatty acids, B160 produced 7 fatty acids, B240 produced 6 fatty acids, whereas B320 produced 9 fatty acids. B320 produced hydrocarbon and phtalic acid as well as fatty acids. Total SFAs and MUFAs of B240 was increased 1.6 times compared to the wild type. The results would give some implications to improve the quality of biodiesel from Botryococcus sp.

“…The exposure of gamma ray produces positive impact at low doses but generates negative impact on high doses that cause inhibition as well as decreasing level of growth and maturity of plant. Besides the irradiation applied on the plant, the effect produced by the exposure of gamma ray irradiation on microalgae also occurs as performed by Ermavitalini et al (2017) in which gamma ray with 10 Gy dose reveals deceleration phase in microalgae growth. The gamma ray radiation caused the cells on microalgae to experience oxidative stress which then triggered the cell to perform defensive process to maintain the growth and reduce the generated stress effect.…”

Diversity Induction of Dendrobium sylvanum Orchid through In Vitro Irradiation of Gamma Ray

2018

View full text Add to dashboard Cite

Dendrobium sylvanum orchid is categorized as lowland habitus orchid and able to survive wihtout any shade. Orchid cultivation takes a very long time so it needs faster cultivation and producing large quantities. Therefore, it is necessary to do orchid culture by using tissue culture processes and then given gamma ray irradiation to bring up new characters in the orchid .The purpose of this research was to discover the impact of gamma ray irradiation in vitro to the diversity of D. sylvanum. The doses of gamma ray used in this research were 0 Gy, 15 Gy, 30 Gy, 45 Gy, and 60 Gy. The results obtained indicated that mutation mostly occurred on the treatment with 15 Gy (4.4 cm of plant height, 2.67 of leaves, 2.36 cm of leaf length, 0.49 cm of leaf width, and 5.33 of root strands) compared to the other doses and the control plants. The new finding in this research is the gamma ray dose that can optimally stimulate the mutation in D. sylvanum. This information is useful to generate the new variety in orchid cultivation in Indonesia. This research provides innovation in orchid cultivation and new variety that is possible to arise after the mutation.

Metabolic response of Botryococcus braunii to high bicarbonate dosages and other conditions: analysis of photosynthetic performance, productivity, and lipidomic profile

et al. 2021

View full text Add to dashboard Cite

In this study the metabolic responses of Botryococcus braunii were analyzed upon different inorganic carbon dosages and nutrient limitation conditions in terms of lipid and biomass productivity, as well as photosynthetic performance. The nutritional schemes evaluated included different levels of sodium bicarbonate and nitrogen and phosphorus starvation, which were contrasted against standard cultures fed with CO2. Bicarbonate was found to be an advantageous carbon source since high dosages caused a significant increase in biomass and lipid productivity, in addition to an enhanced photosynthetic quantum yield and neutral lipids abundance. This contrasts to the commonly used approach of microalgae nutrient limitation, which leads to high lipid accumulation at the expense of impaired cellular growth, causing a decline in overall lipid productivity. The lipidome analysis served to hypothesize about the influence of the nutritional context on B. braunii structural and storage lipid metabolism, besides the adaptive responses exhibited by cells that underwent nutrient stress.
