High levels of organic matter and heavy metals in domestic wastewater can increase the pollution of water bodies. The water pollution results correspond to the degree of public health. Waste must be controlled and processed first using management methods such as biophytoremedyator to decrease the rate of pollution because its advantages do not negatively impact public health and the environment. Biophytoremediation offers a better alternative method to repair environmental conditions by combining microorganisms and plants. This study aimed to analyze the effect of heterotrophic bacterial strains with Pistia stratiotes L. and Salvinia molesta D. Mitch for heavy metal removal in domestic wastewater. It also investigated the influence of heterotrophic bacterial strains with Pistia stratiotes L. and Salvinia molesta D. Mitch which were also carried out to observe the BOD and COD levels. The results showed decreased heavy metal levels from the three treatment groups. The consortium treatment group of heterotrophs and Salvinia molesta D. Mitch bacteria strains reduced heavy metal levels faster than the other groups by 59%. In addition, it is also able to reduce BOD and COD levels. This study has shown the significant effect of combining heterotrophic bacterial (HB) strains with Pistia stratiotes L. or Salvinia molesta D. Mitch for heavy metal removal in domestic wastewater.
生活废水中高浓度的有机物和重金属会加重水体的污染。水污染的结果与公共健康的程度相对应。必须首先使用诸如生物植物修复剂之类的管理方法来控制和处理废物，以降低污染率，因为其优点不会对公众健康和环境产生负面影响。生物植物修复是一种将微生物和植物结合起来修复环境条件的较好的替代方法。本研究旨在分析异养菌对生活污水中重金属的去除效果。并研究了异养菌株对水环境生化需氧量(BOD)和COD水平(COD)的影响。结果显示，三个治疗组的重金属含量都有所下降。异养菌与Salvinia molesta D. Mitch菌群联合处理组重金属水平下降速度比其他组快59%。此外，它还能够降低BOD和COD水平。本研究表明，异养细菌(HB)菌株与Pistia stratiotes L.或Salvinia molesta D. Mitch组合对生活废水中重金属的去除效果显著。

To extend plant benefits, three different concentrations of five Morinda citrifolia part was investigated on the collagen type II which is the primary collagen in human cartilage through the expression of the genes, COL2A1, COL-II and COLL2 regions in normal human dermal fibroblasts by qRT-PCR method. The results showed that 1) fibroblasts cultured in the presence of M. citrifolia extracts produced many times more collagen type II gene expression than control cells depending on the plant parts and concentrations, 2) the expression levels of the collagen type II gene stimulated by all fruit parts yields the higher percentages than leaves. Next, Morus alba leaf extract at a concentration expected to be a precursor protein source for collagen synthesis, working together with M. citrifolia stimulation, was added to the selected concentration indicating high expression in the M. citrifolia fruit experiments. The result showed various gene expression levels depended on the kind of gene and fruit part. Therefore, M. citrifolia fruits can benefit the creation of collagen type II with or without M. alba. The M. citrifolia fruit can be further benefited in product production for both the elderly and young for maintaining the typical structure and function of the skin, tendon, and bone.

Chikungunya virus (CHIKV) is an arthropod-transmitted Alphavirus endemic to countries in Africa and Asia, including Indonesia, which causes debilitating arthralgia which can last several years. The rapid spread of CHIKV to new areas makes the discovery of antiviral agents a high priority. α-mangostin is a xanthone from mangosteen (Garcinia mangostana) pericarp and has antiviral activity against Hepatitis C and Dengue viruses. We investigated the antiviral activity of α-mangostin against CHIKV in HepG2 cells in pre-, post- and combination treatments compared to the common antiviral medicine ribavirin, as well their cytotoxicity. Our results show dose-responsive reductions in viral titer in all treatment regimes, with post- and combination treatments being more effective than pre-treatment only (IC50 = 7.79, 5.99 and 6.39 µM, respectively), but with poor specificity (SI = 1.39, 1.81 and 1.70, respectively) compared to ribavirin. Neither compound showed a direct virucidal effect. These results suggest α-mangostin effectively inhibits CHIKV replication in this cell line.

The use of mouthwash is one of the actions against biofilms that are often used. However, commercial mouthwashes have a fairly high alcohol content, which is around 26.9% of the total volume, which is considered to have a prolonged impact where high alcohol content in direct contact with the oral mucosa can cause lesions or abnormalities, resulting in a shift in the medical paradigm towards eco-friendly widely considered as a solution. Propolis with antibacterial ability was formulated using the nanoemulsion steps, which were initiated by separating pure propolis through drying, and then there were variations in the formulation of 3 types of bee propolis: Heterotrigona itama, Tetragonula sapiens, and Tetragonula clypearis along with the addition of Tween 80, propylene glycol, glycerin and then the effect on microbial growth of S. mutans was compared with antimicrobial agents in Brazilian propolis with the identification and comparison of the antibacterial activity stability of the organoleptic formula. Where the active ingredient content of propolis is the highest in H. itama propolis with a total flavonoid content of 38.94 mgQE/L sample and T. clypearis propolis has the lowest total flavonoid content of 14.23 mgQE/L sample with its function as an anti-oral biofilm agent by inhibiting the glucosyltransferase was proven with a minimum percentage of 49% inhibition of S. mutans and degradation of 18% with the use of a combined surfactant proved to be able to increase the stability of the preparation shown at 2:1 (v/v).

The forest conversion into oil palm plantations in Belitung impacts the plant source for pollen and nectar to support the honey bee Apis dorsata. This study aimed to identify the plants used by A. dorsata as pollen sources in honey and bee bread in honey bee nests and to analyze the vegetation composition and structure surrounding the sunggau (artificial nesting site) in Belitung Regency. Honey from A. dorsata was collected from bee nests in sunggau on Kampak Island and Tanjung Rusa. The pollen grains from 20 ml honey were acetolysed and counted until 1,200 grains for each honey sample. In Kampak Island, we found eight pollen types in honey dominated by Rhizophora mucronate mangrove pollen and eleven pollen types in bee bread dominated by Melaleuca cajuputi. The pollen type in honey in Tanjung Rusa was similar to those in Kampak Island, and nine pollen types were found in the bee bread dominated by Elaeis guineensis. The vegetation analysis revealed that mangrove and heath forests in Kampak Island were dominated by Lumnitzera littorea and Melaleuca cajuputi, respectively. The results of this study confirm the bees' notable use of the mangrove ecosystem, which adds conservation value, especially in supporting bee management efforts in Belitung.

The pollination of oil palm by Elaeidobius kamerunicus leads to an increase of over 70% in countries such as India, Malaysia, and Indonesia. The impact of insect-microbiome interactions on the pollination activity and fitness of E. kamerunicus is unknown. Our study aimed to gain insight into the bacterial communities of E. kamerunicus from two different sites with high and low fruit set percentages, using culturable and Terminal Restriction Fragment Length Polymorphism (T-RFLP) analysis. Our result revealed distinctive T-RFs profiles in E. kamerunicus from two different sites. Additionally, the culturable approach showed that some of this microbiome were found only in the weevil population from the high fruit set site. Our findings suggest that these bacteria could contribute to the fitness of E. kamerunicus, leading to a higher fruit set in oil palm plantations.

Seagrass is the most common ecosystem in Tanjung Berakit waters. Therefore, Tanjung Berakit waters have a very important role as a benthic foraminiferal habitat. This study was conducted to describe the distribution of benthic foraminifera relating to the environmental condition of the waters. The samples were collected from eight stations by handling garb in November 2017. This study collected 18 species of shallow water benthic foraminifera dominated by Amphistegina and Heterostegina. This study recorded a correlation between the sediment texture and foraminiferal assemblages. The most common foraminifera were inhabiting fine-textured sediments, especially very fine sand and silt. Only a few foraminifers are collected from extremely fine sediments such as clay sediments, or extremely coarse including pebbles.

Fungal spores in the air can be inhaled and enter the human respiratory tract. The entry of fungi into the respiratory tract can cause colonization or infection depending on the host immune response. Fungal colonization is the first step into debilitating fungal disease in humans, especially in immunocompromised groups. The increased rate of drug-resistant fungi has been reported in human disease and the environment. This study aims to examine the diversity of fungal colonization in humans and the rate of fungal resistance to voriconazole. This cross-sectional study was done in patients with naïve lung cancer who had not been previously treated with any cancer therapy nor given antifungal agent. Induced sputum from 70 subjects was collected and inoculated in the Sabouraud Dextrose Agar medium. Macroscopic and microscopic examinations were performed to identify fungal species. Voriconazole susceptibility tests were done using the disc diffusion method. This study found Candida albicans, Aspergillus niger, Aspergillus fumigatus, and Penicillium sp. among the most common lower respiratory tract colonies. This study also found the colonization of up to 5 species in a single subject. A high rate of voriconazole-resistant Aspergillus sp. was found (42.4%) among 59 isolates tested. Given that these subjects had never taken antifungal agents previously, the high rate of voriconazole resistance might be attributed to the environment, such as community and agriculture. Mitigation of antifungal use in the agricultural sector, fungal diversity in the environment, and clinical study of fungal colonization/ infection in other high-risk groups are needed.

Pegler suggested that shiitake comprises three morphological species: Lentinula edodes (continental and northeast Asia), L. lateritia (tropical Asia and Australasia), and L. novae-zelandiae (New Zealand). The current study reported for the first time the occurrence of L. lateritia (Berk.) Pegler in Indonesia. During a fungus foray in Kerinci (Jambi, Sumatra, Indonesia) in 2022 and 2023 by the Indonesian mushroom hunter community, some basidiomata of Lentinula were obtained. At a glance, our specimens resembled L. edodes. The current study aims to justify the taxonomical position of our specimens based on morphological and molecular data. The fresh basidiomata were used for morphological and molecular analyses. The molecular work was done using ITS 4/5 Primers for phylogenetic analysis of rDNA-ITS region. Morphologically, the uniformly reddish brown, smooth, and glabrous of pileus confirmed our specimens as L. lateritia. In addition, the absence of a range of colors and squamules pileus distinguished L. lateritia BO24628 form L. edodes, while the formation of florets cheilocystidia in L. madagasikarensis was the distinctive character of our specimens. The BLAST result revealed that our specimen has high similarity (99-100%) with L. lateritia and L. edodes as the top hits. The phylogenetic tree (RAxML) nested our specimens in the L. lateria clade and is closely related to one specimen from Papua New Guenia (PNG) (BS 98%). In addition, L. lateritia BO24628 has a sister clade of the specimen from PNG and Australia. Moreover, we provide the herbarium collection of wild L. lateritia in Indonesia.

The current study reported for the first time the occurrence of L. lateritia (Berk.) Pegler in Indonesia. During a fungus foray in Kerinci (Jambi, Sumatra, Indonesia) in 2022 and 2023 by the Indonesian mushroom hunter community, some basidiomata of Lentinula were obtained. At a glance, our specimens resembled L. edodes. The current study aims to justify the taxonomical position of our specimens based on morphological and molecular data. The fresh basidiomata were used for morphological and molecular analyses. The molecular work was done using ITS 4/5 Primers for phylogenetic analysis of rDNA-ITS region. Morphologically, the uniformly reddish brown, smooth, and glabrous of pileus confirmed our specimens as L. lateritia. In addition, the absence of a range of colors and squamules pileus distinguished L. lateritia BO24628 form L. edodes, while the formation of florets cheilocystidia in L. madagasikarensis was the distinctive character of our specimens. The BLAST result revealed that our specimen has high similarity (99-100%) with L. lateritia and L. edodes as the top hits. The phylogenetic tree (RAxML) nested our specimens in the L. lateria clade and is closely related to one specimen from Papua New Guenia (PNG) (BS 98%). In addition, L. lateritia BO24628 has a sister clade of the specimen from PNG and Australia. Moreover, we provide the herbarium collection of wild L. lateritia in Indonesia.","PeriodicalId":12927,"journal":{"name":"HAYATI Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43668303","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}

The mangrove ecosystem is unique because it is located between marine and land. Little research is exploring lactic acid bacteria (LAB) from mangrove ecosystems. The LAB LG71 isolate is successfully isolated from the sediment of mangrove ecosystems on the coast of Logending, Jawa Tengah (Indonesia). In this study, we aimed to know the effect of glucose supplementation on the growth of LG71 isolate, bacteriocin production, and its application in food preservation. The characterization results showed that the LG71 isolate is Lactobacillus sp. Interestingly, the LG71 isolate is catalase-positive since this character is rarely found in the LAB group. Supplementing 0.25% glucose to MRSB medium and an incubation time of 15 hours is the best treatment for producing Lactobacillus LG71 isolate cell biomass. A 2% concentration of crude extract of Lactobacillus LG71 bacteriocins is the best concentration against Salmonella typhi both during in vitro and in vivo tests in fish balls. The addition of glucose affects the production of Lactobacillus LG71 cell biomass, and the bacteriocin derived from Lactobacillus LG71 gives increased protection against S. typhi and offers an alternative for food preservation.
