The use of laboratory animals such as rabbits is required for antibody production in immunoassay‐based detection. However, due to its many advantages, specific chicken egg yolk immunoglobulin (IgY) has received considerable attention as an alternative antibody production in immunodiagnostics for infectious diseases. In this study, IgY antibody against SCMV recombinant coat protein (CP) was successfully obtained from chicken blood serum and tested to compare its efficacy against antibody from rabbit (IgG) using immunocapture reverse transcription‐polymerase chain reaction (IC‐RT‐PCR). The result showed that IgY and IgG could detect 0.1 g SCMV infected leaves using 1000‐times‐diluted antibodies. The IgY antibody was also confirmed to be reproducible and potentially applicable in plant disease diagnostics using an antibody‐based detection.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44118816","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}

IL‐10 and TGF‐β act as robust anti‐inflammatory cytokines in accelerating the wound healing process by regulating myofibroblasts. Hypoxic mesenchymal stem cell‐conditioned medium (hypMSC‐CM) containing cytokines potentially contribute to accelerate wound repair without scarring through the paracrine mechanism. This study aims to observe the role of hypMSC‐CM in controlling TGF‐β and IL‐10 levels to accelerate full‐thickness wound repair and regeneration. A total of 24 male Wistar rats were used in this study. Six healthy rats as a sham group and 18 rats were created as full‐thickness‐wound animal models using a 6 mm punch biopsy. The animals were randomly assigned into three groups (n = 6) consisting of two treatment groups treated with hypMSC‐CM at a low dose (200 µL hypMSC‐CM with 2 g water‐based gel added) and a high dose (400 µL hypMSC‐CM with 2 g water‐based gel added) and a control group (2 g water‐based gel only). The IL‐10 and TGF‐β levels were examined by ELISA. The results showed a significant increase in IL‐10 levels on day 3 after hypMSC‐CM treatment, followed by a decrease in platelet‐derived growth factor (PDGF) levels on days 6 and 9. In line with this finding, the TGF‐β levels also increased significantly on day 3 and then linearly decreased on days 6 and 9. HypMSC‐CM administra‐ tion may thus promote wound healing acceleration by controlling IL‐10 and TGF‐β levels in a full‐thickness‐wound rat model.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44183714","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}

However, the chemical process often produces a by‐product that may be harmful to human health. Therefore, this study established a protocol to induce hairy roots (HRs) from a Vietnamese carrot variety and produce natural β‐carotene. The Rhizobium rhizogenes ATCC15834 harbouring Ri plasmid and a Vietnamese carrot variety were used as materials for genetic transformation and HR induction studies. The result showed that approximately 50 HR lines were obtained. Culture medium supplemented with 30 mg/L of sucrose that gave the highest biomass of HR was shown in carrot HR line 30, which had a doubling time of 6.5 days. The highest content of β‐carotene extraction, at 128 mg/100g hairy roots, was achieved with a ratio volume (v/v) of 2‐propanol and plant samples of 20:1, followed by two hours’ incubation with 2‐propanol at 60 °C. Our study reveals a highly efficient protocol for Vietnamese carrot hairy root establishment and multiplication. A very efficient protocol for β‐carotene extraction from the hairy root was established to produce natural β‐carotene that achieves the same β‐carotene quantity as that produced by normal roots. This study provides new insight into the production of high‐content and natural β‐carotene for therapeutic application.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45089616","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 treatments included a control (no EO addition), galangal EO (30, 60, 120 µL), and cineole (5 µL). The treatments were assessed using a 48‐hour in vitro batch culture of rumen fluid containing a 60:40 ratio of forage to concentrate. For amplification of the prokaryotes (bacteria and archaea) in region V4, 16s rRNA primer 5’GTGCCAGCMGCCGCGTAA, GGACTACHVGGGTWTCTAAT3’ was employed. The data for rumen microbial abundance were analysed descriptively, while the data for rumen microbial diversity were obtained from the report on the Next Generation Sequencing Method. The microbial composition of each sample was tested for operational taxonomic units (OTUs) with a 97% identity rate on a valid label. The 16S rRNA gene sequencing yielded a total of 3,977 OTUs. Adding galangal and cineole EOs resulted in the same variation of the Shannon index. The population index (chao1 index) was highest when 60 µL of galangal EO was added, compared to 30 and 120 µL of galangal EO and cineole. In addition, providing 60 µL of galangal EO decreased the abundance of Prevotella ruminicola compared to the control and cineole doses. The addition of galangal EO also led to a decline in the number of Methanobacteriales. The population of the fibre‐degrading bacteria group (Ruminococcus albus and Ruminococcus flavefaciens) was higher in a dose of galangal EO than the control and cineole. Therefore, it can be concluded that the effective dose of galangal EO, i.e. 60 µL/300 mg (DM feed) in vitro, can reduce the abundance of Prevotella bacteria and methanogens.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44318660","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}

Nevertheless, the comprehensive mechanism of action has yet to be determined. Andrographolide is a primary component of the sambiloto herb (Andrographis paniculata (Burm.f.) Nees), in which a simple isolation process can obtain high yields. This study aimed to explain the anti‐diabetic effect of andrographolide compared to pioglitazone (a positive control) on glucose uptake by measuring the expression levels of peroxisome proliferator‐activated receptor gamma (PPARγ) and glucose transporter type 4 (GLUT‐4) genes in 3T3‐LI mouse adipocytes as an in vitro model. The differentiation of mature adipocytes from 3T3‐L1 fibroblasts was induced with 3‐isobutyl‐1‐methylxanthine, dexamethasone, and insulin. Andrographolide was provided through direct isolation from A. paniculata herbs. The gene expression was detected using the reverse transcription‐polymerase chain reaction (RT‐PCR). Pioglitazone and andrographolide significantly increased glucose uptake capability. Andrographolide was able to increase the mRNA levels of PPARγ and GLUT‐4 compared to pioglitazone with the best concentration at 5.6 µM. In conclusion, andrographolide can improve glucose uptake by increasing mRNA levels of PPARγ and GLUT‐4 that encodes protein, which are key factors for glucose homeostasis. Therefore, this finding further establishes the potency of andrographolide from A. paniculata as an antidiabetic.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44546373","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}

Bacteria from Cisadane River water samples were isolated by the spread plate method on Luria Bertani medium containing 3 mM CuSO4. Resistance was determined based on the minimum inhibitory concentration value, while copper concentration was measured using an atomic absorption spec‐ trophotometer. The results presented a total of 13 bacterial isolates with a minimum inhibitory concentration of up to 8 mM CuSO4.

It is necessary to explore extracellular enzymatic activity in several microorganisms to discover a new potential application from amylases. In a previous study, thermophilic bacteria Geobacillus sp. DS3 isolated from Sikidang Crater, Dieng Plateau, Central Java, Indonesia showed amylase activity in starch medium at 70 °C. This study aimed to purify and characterize the thermostable alpha‐amylase from Geobacillus sp. DS3. The alpha‐amylase was produced and purified using ammonium sulfate and DEAE Sephadex A‐25 column. The enzyme activity was determined using the 3,5‐dinitrosalicylic acid (DNS) method. Geobacillus sp. DS3 optimally produced the alpha‐amylase at 60 °C for 15 h. The alpha‐amylase exhibited high enzymatic activity in 40–60% saturated ammonium sulfate extract. The molecular weight of the enzyme was estimated to be 58 kDa. The thermostable alpha‐amylase showed activity at the optimum temperature of 50 °C in 200 mM sodium phosphate buffer pH 7.0. The enzyme was inhibited by EDTA, PMSF, 2‐ME, and mostly by HgCl2. The Km and Vmax of the pure enzyme were 235.43 mM and 1428.57 U/mL, respectively. The result suggested that the purified thermostable alpha‐amylase from Geobacillus sp.
