It has a diverse microorganism, especially actinomycetes group, which might potentially produce beneficial secondary metabolites that remain unknown. In this study, we were interested in isolating Dactylosporangium and Micromonospora that have been potentially reported as antibiotic sources. We used two methods using the chemical germicide (pretreatment 1.5% phenol) compared with the SDS-YE (0.05% SDS pretreatment). Thirty-nine isolates actinomycetes were successfully isolated from two samples of the karst cave soils. Thirteen isolates were obtained by using the germicide chemical method and closely related to the genera of Dactylosporangium and Micromonospora. On the other hand, the SDS-YE grew twenty-six isolates which closely related to 11 genera of actinomycetes (Catenulispora, Nocardia, Rhodococcus, Ornithinimicrobium, Catellatospora, Dactylosporangium, Micromonospora, Streptacidiphilus, Streptomyces, Nonomuraea, and Streptosporangium). These results suggest that 1.5% of phenol pretreatment could preserve the genera of Dactylosporangium and Micromonospora, while the Streptomyces and other rare actinomycetes were killed. Among all isolates, only 7 showed the antibacterial activity on tested bacteria. Even though the antibacterial activity of those isolates was not high, the isolation of actinomycetes from a specific substrate is necessary to be conducted on exploring the richness of our natural resources.

In some Asian countries, the fruits are consumed as traditional medicine and food ingredient. Meanwhile in Indonesia there has not been much use. A series of oral toxicity tests must be conducted to study the possibility of toxic effects and the safety before further exploration. Oral single dose toxicity study of young and ripe hairy fig fruit filtrate has been carried out. Results demonstrated no observed adverse effect level (NOAEL) at a concentration of 100%. This study was aimed to continue the oral toxicity test with repeated dose following standard toxicity procedure by OECD Test Guideline No. 407 with some modifications. Parameters observed were mortality, sublethal effects consisted of physical conditions and behavior, body weight, core temperature, complete blood count, as well as liver, heart, and renal functions by measuring ALT, AST, and creatinine, respectively. Sampling points on day 0, 7, 14, 21, and 28. Results showed no observed adverse effect level (NOAEL) in both young and ripe fruits filtrate at a concentration of 100% however with a tendency to cause anemia and associate with renal dysfunction.

This study examines the growth and productivity of Oedogonium sp. under different light intensity in laboratory scale. The main research includes Oedogonium sp. culture, measurement of growth (doubling time (DT) and relative growth rate (RGR)), measurement of primary productivity, and the effect of light measurement on cells through observation of histological preparations. The results showed that Oedogonium sp. on indoor culture showed negative growth (RGR of -0.054), whereas in semi-outdoor culture showed positive growth (RGR 0.046 - 0.47 g / day and DT for 14.72 - 15.09 days. Primary productivity and respiration in 1000 lux lighting cultures showed greater value than cultures in 650 lux lighting. The length of Oedogonium sp. ranged from 18.68 - 34.47 µm in dark light, 51.33 - 95.00 µm in moderate light, and 48.83 - 70.75 µm in bright light. This study showed that in indoor culture, the availability of light, temperature, pH and DO significantly affect the growth of Oedogonium sp., whereas in semi-outdoor culture, temperature, pH and DO factors was not limiting factors.

The aim of this study is to identify the effect of black cumin cream on collagen levels and hydration of the skin of Rattus norvegicus exposed to ultraviolet-B rays. This is experimental study in which 30 male Wistar strain rats were classified into 6 sub-groups, namely the KN group (without treatment), KP (getting Nivea cream moisturizer), P1 (basic cream ), P2 (black cumin seed extract cream 0.25%), P3 (cream 0.5%) and P4 (cream 0.75%). P4 rat collagen levels increased significantly before and after the intervention (24 ± 2.23 vs 42.6 ± 14.6, p <0.05).Cream with lower concentrations did not provide a significant increase (p> 0.05). P4 rats also showed increased skin hydration (38.6 ± 19.3 to 63.0 ± 4.47 (p <0.05)), and this was not found in other groups. The administration of topical black cumin seed extract 0.75% can inhibit decreased levels of collagen and increase skin tissue hydration.

The presence of alien species can be on threat for the loss of biodiversity in fresh waters, including endemic fish in Lake Matano. The research aim to review the threat of louhan fish as alien species to endemic fish in Lake Matano. The study was conducted in Lake Matano at five stations in April and August 2015 namely Lawa, Nuha, Petea, Pantai Impian, and Pantai Kupu-kupu. Sam-ples were collected using experimental gillnet with mesh size of ¾; 1; 1¼; 1⅟2; 2; 2,5; and 3 inches. Fouteen species were found consist of 10 endemic species and red list.These were three of genus Glossogobius, seven species of Telmatherina, and four alien species of the carp (Cyprinus carpio), louhan, gourami (Trichopodus trichopterus), and tilapia (Oreochromis niloticus). The most common species of endemic fish is T. antoniae. Louhan is the result of a hybrid species Amphilopus citrinellus x Cichlasoma trimaculatum. The abundance of louhan is 64 in April and 40 fishes in August, respectively at a time caught. The percentage ratio of louhan to endemic fish was of 8.6% and 18.3%. This indicated that the louhan fish tend to be invasive and certainly threatened endemic fish survival in this lake. The maturity of gonads of louhan is in the level of I - IV that enables the fish to reproduce quickly.","PeriodicalId":280065,"journal":{"name":"BERITA BIOLOGI","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127031076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
