“…This condition certainly affected the diversity and morphology of the seaweed (Erlania and Radiarta 2017;Widyartini et al 2017;Romdoni et al 2018). In addition, this condition certainly affected the flora and fauna diversity in both places (Putri et al 2017;Utami et al 2017;Rahmawati 2021;Sabdono et al 2021). Previous studies have reported that seaweed from Chlorophyta and Rhodophyta are diverse in the Gunung Kidul region, while in Jepara is dominated by the Phaeophyta division (Wulandari et al 2015;Chasani and Suyono 2020).…”

Abstract. Sibero MT, Frederick EH, Sabdono A, Wijayanti DP, Pringgenies D, Radjasa OK, Zilda DS, Murwani R. 2022. First report of seaweed-associated yeast from Indonesia: Species composition and screening of their polysaccharides-degrading enzymes. Biodiversitas 23: 1408-1419. Yeast has been widely utilized in various industries due to its enzyme properties. Therefore, plenty of studies focus on exploring yeast biodiversity from diverse sources. However, there are limited reports regarding marine yeast biodiversity and its potential from Indonesia. This study aimed to isolate and identify the seaweed-associated yeast from Jepara in Central Java and Sepanjang Beach in Gunung Kidul, Yogyakarta, then examined their potential to produce extracellular polysaccharides-degrading enzymes (EPEs). Marine yeasts were isolated using standard marine agar (STD) and potato dextrose agar (PDA). All isolates were characterized by their salinity tolerance, morphology, and species confirmation using DNA barcoding. Three EPEs consisting of agarase, alginate-lyase, and carrageenase were screened using polysaccharides-enriched agar media. A specific agarase encoding gene was detected with specific primers. In total, 21 seaweed-associated yeast were successfully isolated from 6 seaweeds and noted as facultative marine yeast. The DNA barcoding study discovered that these yeasts belonged to 5 genera, consisted of Aureobasidium, Candida, Debaryomyces, Hortaea, and Rhodotorula. Moreover, Candida was noted as the most abundant genus (71.42%). It was noted that Hortaea werneckii MTJ.11 and MTJ.13 were positive for all enzymes; Aureobasidium melanogenum MTGK.31 gave a positive result for agarase and carrageenase; while [Candida] zeylanoides MTGK.23 only exhibited alginate-lyase activity. Unfortunately, none of the primers used to detect the presence of genes encoding polysaccharide-degrading enzymes were successfully amplified.

“…Selanjutnya Salosso & Jasmanindar (2018), juga menyampaikan pemanfaatan makroalga dalam bidang industri terkait dengan kandungan karagenan, agar dan alginat. Pemanfaatan makroalga dalam bidang pangan juga telah disampaikan oleh Nurmiyati (2013); Putri et al (2017), bahwa jenis Ulva lactuca telah dimanfaatkan sebagai sayuran atau keripik untuk olahan khas Gunungkidul. Selanjutnya jenis Caulerpa racemosa dimanfaatkan sebagai sayuran untuk pecel, oseng ataupun lalapan, dan jenis Gracilaria arcuata dijual secara langsung ke tengkulak sebagai bahan agar (Nurmiyati, 2013).…”

Penelitian ini bertujuan untuk mengetahui kandungan fitokimia pada berbagai jenis makroalga di Pantai Jungwok, Kabupaten Gunungkidul, Yogyakarta. Penelitian ini dilaksanakan di Pantai Jungwok, Kabupaten Gunungkidul, Yogyakarta. Materi penelitian ini adalah makroalga (Ulva sp., Gracillaria sp., dan Boergesenia sp). Metode yang digunakan dalam penelitian ini adalah survei dengan pendekatan kualitatif. Teknik pengambilan sampel makroalga menggunakan purposive sampling. Lokasi pengambilan sampel makroalga berada di bagian timur, tengah dan barat Pantai Jungwok. Analisis skrining fitokimia dilakukan dengan uji kualitatif. Analisis skrining alkaloid menggunakan metode Culvenor Fitzgerald, sedangkan untuk steroid dan terpenoid menggunakan metode Liebermann-Buchard Test, pada fraksi air yang terbentuk dilanjutkan dengan uji flavonoid, fenolik dan safonin. Hasil penelitian menunjukan bahwa sampel segar makroalga jenis Gracilaria sp., yang berada di bagian tengah Pantai Jungwok paling banyak mengandung senyawa bioaktif seperti alkaloid, terpenoid dan flavonoid. The objective of this research was to identify the content of phytochemical in various types of macroalgae at Jungwok Beach, Gunungkidul District, Yogyakarta. This research was conducted at Jungwok Beach, Gunungkidul District, Yogyakarta. The material of this research were macroalgae (Ulva sp., Gracillaria sp., and Boergesenia sp.). This method of research used survey with a qualitative approach. The technique of collecting data was done through purposive sampling. The macroalgae samples were collected from the eastern, central and western part of Jungwok Beach. The phytochemical tests were carried out using qualitative test. Alkaloid screening analysis using the Culvenor Fitzgerald method, while for steroids and terpenoids using the Liberman Buchard Test method, the formed water fraction is followed by flavonoid, phenolic and safonin tests. The results showed that fresh sample of the macroalgae type Gracilaria sp., which is located in the middle of Jungwok Beach, contains the most bioactive compounds such as alkaloids, terpenoids and flavonoids.
