摘要

红树林地区被广泛报道为一个富含微藻的地方,这些微藻产生欧米伽-3二十二碳六烯酸(DHA)和其他具有高经济价值的生物活性物质。2022年4月,在雅加达Seribu群岛Pari岛的红树林地区进行了微藻搜索,并由FKIP UHAMKA生物教育实验室确定。本研究的目的是从印度尼西亚红树林森林中收集Aurantiochytrium属和Thraustochytriidae科其他成员的新菌株或分离物的长期目标的一部分。本研究采用纯条纹法分离微藻,并对其进行形态鉴定。本研究成功获得了8株分离菌株(UHA1、UHA3、UHA5、UHA6、UHA10、UHA11、UHA12和UHA13),从菌落外观和微观形态上来看,它们是Aurantiochytrium sp.。其中一株分离菌株(UHA12)以葡萄糖、酵母提取物和海水为培养基,在Erlenmeyer瓶中分批培养5天。结果表明,所获得的干生物量几乎与其他著名的Aurantiochytrium sp.相当

Exploration Of High Economic Value Microalgaes In The Mangrove Area Of Pari Island, Seribu Islands, Jakarta
Mangrove areas are widely reported as a place of abundance of microalgae producing omega-3 docosahexaenoic acid (DHA) and other bioactive materials of high economic value from the genus Aurantiochytrium. The search for microalgae was carried out in the mangrove area of Pari Island, Seribu Islands, Jakarta, in April 2022 and identified at the Biology Education Laboratory, FKIP UHAMKA. The purpose of this study is part of the long-term goal of collecting new strains or isolates from the genus Aurantiochytrium and other members of the family Thraustochytriidae from forests in Indonesian mangroves. This research was conducted by isolating microalgae with the pure streaking method and identifying them morphologically. This study succeeded in obtaining eight isolates (UHA1, UHA3, UHA5, UHA6, UHA10, UHA11, UHA12, and UHA13) which in the appearance of colonies and microscopic morphology lead to the species Aurantiochytrium sp. One of the isolates obtained (UHA12) was cultivated by batch culture for five days in an Erlenmeyer flask using glucose, yeasts extract, and seawater as a medium. The result is that the dry biomass obtained is almost equivalent to that of the Aurantiochytrium sp. other famous
