“…The strong antifungal activity of antagonistic bacteria is thought to be caused by the influence of nutrition and the environment present in each combination of carriers. According to Murniasih et al (2018), the antifungal activity of antagonistic bacteria in growth media is influenced by nutrients (especially carbon and nitrogen) and environmental conditions (temperature, salinity, and pH) [22]. Widiantini et al (2018) added, the ability of an antagonistic bacterium to produce secondary metabolites is influenced by the nutrient content in the media, environmental factors, and storage time [23].…”

This study examines the ability of liquid organic waste carriers to increase the antifungal activity of the active ingredient Bacillus sp DB12, which has been stored for 12 weeks against the pathogen Fusarium oxysporum f.sp. cepae. The research method was carried out in an experimental laboratory using a completely randomized design (CRD) with a single factor in the form of a liquid waste carrier consisting of 9 treatments. The composition of liquid tofu waste (TLW), coconut liquid waste (CLW), and rice washing liquid waste (RLW) was determined as follows: 100% TLW, 75% TLW + 25% CLW, 50% TLW + CLW 50%, TLW 25% + CLW 75%, CLW 100%, TLW 75% + RLW 25%, TLW 50% + RLW 50%, TLW 25% + 75% RLW, and 100% RLW. The results showed that the combination of 75% TLW + 25% CLW carriers increased the antifungal activity of Bacillus sp. DB12 compared to other carrier combinations. An increase in antifungal activity was indicated by an inhibition zone diameter of 13.03 mm during 12 weeks of storage.

“…There are ten bacterial phyla that are symbiotic with sponges namely Proteobacteria, Nitrospira, Cyanobacteria, Bacteriodetes, Actinobacteria, Chloroflexi, Planctomycetes, Acidobacteria, Poribacteria and Verrucomicrobia [24]. Symbiotic bacteria with sponge produce secondary active metabolite compounds as potential antibacterial pathogens Staphylococcus aureus, Bacillus subtilis and Vibrio eltor [26]. Furthermore, the natural material produced by the symbiont bacteria is a type of chlorinated, neuroactive, antimicrobial compound that can be used as a raw material for antibiotic drugs [27].…”

Aquaculture is an important sector for Indonesian economic, however, the spreads of diseases during farming remains a problem in developing Indonesian aquaculture. The sponge is known as the source of potential bioactive to combat pathogenic diseases in aquaculture. However, the intensifying exploitation of wild sponge tends to the depreses population of sponges in nature. This article reviews bioactive originating from sponges and potential methods in developing sponges cultivations under in-situ and ex-situ methodologies.

Spons merupakan merupakan biota filter feeder yang mengandung mikroba laut hingga 40 % dari volumenya (Murniasih et al, 2016). Jamur simbion merupakan salah satu sumber metabolit sekunder yang sangat produktif (Amira et al, 2009).…”

Utilization of Sponges Symbiotic Fungus in the Bioisomeration of Fatty Acids in Brans to Produce Cis Fatty Acid Trans fatty acids are known to have a negative impact on human health such as triggering the coronary heart and blood vessel related diseases. However, many food and animal feed contain trans fatty acids. Bran, which is widely used as animal feed has high fatty acid content and the majority are trans fatty acids. This study aims to determine the potential of Trichoderma harzanum, a sponge symbiont fungus, in the process of fatty acid bioconversion in bran. Bran was fermented in saline and non-salin condition for 15 days in the room temperature. Both fermented and not bran was extracted with methanol, and the extracts were concentrated with rotary evaporator. Fatty acid extracts were analyzed on the GC with hydrolysis and methylation as pre-treatments. The test results showed the fatty acid composition changed, and the was formation of new fatty acids. The bioisomeration process occurs in the Trans-9-Elaidic acid Methyl esther into Cis-9-Oleic Methyl ester. Cis-9-oleic acid is known as oleic acid which is widely found in olive and sunflowers oil. The fungus has potential as biocatalys for production of cis fatty acid. Asam lemak trans dikenal mempunyai dampak negatif terhadap kesehatan manusia seperti memicu terjadinya penyakit jantung koroner dan penyakit terkait pembuluh darah. Namun asam lemak trans banyak terkandung dalam berbagai jenis bahan makanan maupun pakan ternak diantaranya adalah dedak. Dedak banyak digunakan sebagai pakan ternak mempunyai kandungan asam lemak yang tinggi dan mayoritas adalah asam lemak trans. Penelitian ini bertujuan untuk mengetahui potensi jamur simbion spons Trichoderma harzanum dalam proses biokonversi asam lemak pada dedak. Fermentasi dedak dilakukan dalam kondisi salin dan unsalin selama 15 hari pada suhu ruang. Dedak yang difermentasi maupun tidak kemudian diekstrak dengan metanol kemudian dipekatkan dengan rotari eveporator. Ekstrak asam lemak degan GC dengan pre-treatment meliputi hidrolisis dan metilasi. Hasil uji menunjukan adanya perubahan komposisi dan terbentuknya asam lemak baru. Proses bioisomerasi terjadi pada Trans-9-Elaidic acid Methyl estermenjadi Cis-9-Oleic Methyl ester. Cis-9-oleic acid yang dikenal dengan asam oleat yang banyak terdapat dalam minyak zaitun dan bunga matahari. Jamur T. Harzianum mempunyai potensi sebagai biokatalis untuk memproduksi asam lemak cis.
