Abstract

This study aims to isolate Lactic Acid Bacteria (LAB) from traditional fermented food of kapiek fish (Barbonymus schwanenfeldii) from Pangkalan Serai Village, Kampar Kiri Hulu, Riau which has antibacterial activity and is a candidate for biopreservative agent. The methods used in this study were isolation, partial characterization, antibacterial activity test, and biopreservative test. The results showed that the initial isolation and characterization of pakasam obtained 2 isolates (isolate P1 and isolate P2) known as the genus Enterococcus spp. and 3 isolates (isolate P3, isolate P4 and isolate P5) from the genus Lactobacillus spp. Isolate P5 has the potential as a candidate for probiotic agent because it can grow at pH 3, extreme salt content, and has broad-spectrum antibacterial activity. Isolate P5 has the potential as a candidate activity against Escherichia coli ATCC 35128 of 8.5 ± 0.8 mm and Staphylococcus aureus ATCC 29213 of 6.6 ± 0.1 mm after the cell-free supernatant was heated for 15 minutes at 100ºC. Key words: Lactic Acid Bacteria, Pakasam, Probiotics, Biopreservative

Abstract

This study aimed to determine the types and detect the content of secondary metabolites of macroscopic fungi that are predominantly found in the Sultan Syarif Hasyim Forest Park. The method used in this study was an exploratory method in logged-over areas. The macroscopic fungi found were identified, and the dominant fungi were tested for chemical compounds such as alkaloids, flavonoids, tannins, terpenoids, steroids, and saponins. The morphological characteristics observed were referenced in identification books, applications such as Mushroom Identifier, and websites: champignouf.com and inaturalist.org. Based on the results of the identification of macroscopic fungi in the Sultan Syarif Hasyim Grand Forest Park in Riau Province, there are 10 families with 18 types of macroscopic fungi, namely Fomes fomentarius, Lentinus sp., Microporus affinis, Microporus xanthopus, Pycnoporus sanguineus, Trametes pubescens, Trametes ochracea, Trametes villosa, Auricularia mesenterica, Crepidotus sp., Baeospora myosura, Ganoderma lobatum, Galerina sp., Gymnopilus sp., Fomes fomentarius, Mycena galericulata, Oudemansiella furfuracea, Nigroporus vinosus, Suillus bovinus, and chemical compound testing was conducted on 6 types of fungi, namely Fomes fomentarius, Microporus xanthopus, Microporus affinis, Pycnoporus sanguineus, Ganoderma lobatum, and Trametes ochracea. All dominant fungal species showed positive saponin results. Fomes fomentarius and Ganoderma lobatum showed positive terpenoid results. In conclusion, this study found macroscopic fungi that have potential as medicine.

Abstract. Linda TM, Febriarti BL, Zul D, Sofyanti N, Berlyansah A, Delfira N, Devi S. 2023. Isolation and characterization of endophytic bacteria from sterile leaf of Acrostichum aureum from Bengkalis Island (Riau, Indonesia) and its potency for antidiabetic. Biodiversitas 24: 1580-1588. Endophytic bacteria are found in symbiotic plant tissues. These bacteria pose potential sources for the natural product due to their health benefit, e.g., for antidiabetic activity. The present study aimed to isolate and characterize endophytic bacteria isolates from the sterile leaf of sea fern (Acrostichum aureum Linn.) from Bengkalis Island (Riau Province), Indonesia. Furthermore, to investigate their potency as an antidiabetic agent. The characteristics of isolates bacteria were described based on colony morphology and biochemical tests. A total of six endophytic bacteria were isolated from the sterile leaf of Acrostichum aureum. Their characteristics vary in shape, color, and size. The phytochemical screening indicated the presence of alkaloids and saponin in all the isolates. The results exhibited that the extract of the sterile leaf of A. aureum also gave a similar phytochemical compound of isolate endophytic bacteria. The dendrogram constructed from morphological and biochemical characteristics showed the separation of D.SB 4.2 from other six bacteria strains due to the positive antibacterial activity for Escherichia coli ATCC35218, Staphylococcus aureus ATCC29213, Salmonella typhi ATCC14028, and Bacillus subtilis ATCC11774. Out of six isolates, only isolate D.SB 5.2 was selected for the antidiabetic test. The isolates showed positive results on the activity as a-amylase inhibitor (18.12%). This study provides important information on endophytic bacteria isolates on A. aureum and their potency for antidiabetic agents.

Abstract

Bakteri rizosfer merupakan bakteri yang hidup di sekitar daerah perakaran tanaman dan berperan penting dalam meningkatkan ketersediaan unsur hara. Salah satu unsur hara penting yang dibutuhkan tanaman adalah kalium, yang terlibat dalam berbagai proses fisiologis tanaman. Namun, sebagian besar kalium dalam bentuk senyawa mineral tidak larut sehingga ketersediaannya di dalam tanah terbatas. Bakteri pelarut kalium dapat meningkatkan jumlah kalium yang tersedia dalam tanah, melalui mekanisme konversi kalsium menjadi bentuk terlarut. Penelitian ini bertujuan untuk mengisolasi dan mengkarakterisasi bakteri pelarut kalium dari rizosfer tanaman padi di Desa Pembatang, Kecamatan Pangean, Kabupaten Kuantan Singingi, Riau. Isolasi bakteri dilakukan menggunakan medium Alexandrov dengan sumber K feldspar (KAISi3O8), pH medium 7 dengan waktu inkubasi pada suhu ruang selama 7 hari. Karakterisasi terhadap isolat bakteri pelarut kalium meliputi makroskopis, mikroskopis dan uji katalase. Hasil penelitian diperoleh empat isolat bakteri pelarut kalium yaitu isolat BPK 1.1, BPK 2.2, BPK 3.1 dan BPK 3.2. Indeks kelarutan kalium tertinggi yaitu isolat BPK 3.2 (2,48). Hasil aktivitas kelarutan kalium isolat BPK 3.2 memiliki indeks kelarutan kalium tertinggi sebesar 2,48. Hasil pewarnaan Gram isolat BPK 3.2 adalah Gram positif, tiga isolat yaitu BPK 1.1, BPK, BPK 2.2 dan BPK 3.1 adalah Gram negatif. Empat isolat bakteri menunjukkan uji katalase positif.

Abstract

The floodplain areas in Sumatra play a crucial ecological and sociological role for aquatic life and surrounding communities. However, this ecosystem faces serious threats from anthropogenic activities such as land conversion into palm oil plantations, infrastructure development (dams), and industrial pollution. This article conducts a literature review regarding the diversity of migratory fish in various floodplain rivers in Sumatra. The review results indicate that the fish community in these areas is dominated by the potamodromous fish group. The Cyprinidae family was found to have the highest number of species. Conservation data show the presence of species with concerning statuses, including an Extinct (EX) status for Chitala lopis and Endangered (EN) for Pangasianodon hypophthalmus, which correlates with massive habitat degradation. This information is expected to support conservation efforts for sensitive species and maintain connectivity between river ecosystems.
