The aim of this study is to increase EPS production by co-culturing Lactobacillus plantarum ATCC 8014 with Saccharomyces cerevisiae ICA-Y01 and study the changes in the functional characteristics of the EPS from both cultivations. In this study, the production and functional characteristics of EPS from co-cultivation culture of L. plantarum ATCC 8014 with S. cerevisiae ICA-Y01 were evaluated. The co-cultivation of L. plantarum ATCC 8014 with S. cerevisiae ICA-Y01was markedly increased EPS production up to 55.84% with 6.8 g/l yield after 20 hours cultivation. The pH of the co-cultivation culture was remained constantly at 5.2 until the end of cultivation. Furthermore, co-cultivation under pH 6 in the 16L bioreactor showed a higher growth rate of 0.214 h-1 and EPS production increased up to 104.44% when compared with single cultivation of L. plantarum ATCC 8014. This result clearly indicates the importance of growing the cells in the controlled pH condition when cultivated with S. cerevisiae ICA-Y01 to enhance EPS production. The functional characteristics of EPS secreted from both cultivation strategies were also evaluated. FT-IR spectroscopy confirmed EPS presence from both cultivations, indicating functional group of the polysaccharide with D-glucose units bound by α-(1→6). The EPS production from single cultivation showed a higher DPPH radical scavenging activity (88.21%) and IC50 (19.57%) as compared to EPS produced from co-cultivation with DPPH scavenging exhibited 32.45% with no IC50 value detected. Furthermore, solubility and water uptake of EPS from single cultivation are higher in comparison to co-cultivation. In conclusion, higher efficiency in the bioactivity of EPS from the single cultivation of L. plantarum ATCC 8014 was confirmed even though the EPS yield is low as compared to EPS synthesis through inter-kingdom cultivation.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76937312","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}

Steviol glycosides (SGs) is the group of secondary metabolites responsible for the sweet taste. Among nine SGs synthesised by S. rebaudiana, stevioside and rebaudioside A are the sweetest. The biosynthetic pathway of SGs partly involves conversion of geranylgeranyl diphosphate (GGDP) into steviol, catalysed by ent- kaurene synthase (KS), ent-copalyl diphosphate synthase (CPPS), and kaurene oxidase (KO). This study focuses on in silico molecular characterization and phylogenetic analysis of KS from Malaysia’s S. rebaudiana MS007 variety (Stevia MS007). The transcriptomic dataset of S. rebaudiana accession MS007 was used in initial experiment toward analysing the KS. Through the blastx homology search using transcriptomic dataset query Cluster-31069.42907, the Stevia rebaudiana kaurene synthase (SrKS) sequence was identified with the highest similarity percentage identity (99.62%). The protein domain prediction using InterPro yields IPR005630 (terpene synthase metal-binding domain) at positions 490 to 755 and IPR001906 (terpene synthase-N-terminal-domain) at positions 258 to 477. Multiple sequence alignment was conducted using MUSCLE and MEGA-X as phylogenetic tree analysis tool for constructing the phylogenetic analysis tree. Based on the bootstrap value from the phylogenetic analysis, Cluster-31069.42907 represents relationships between the ancestors. Since both Helianthus annuus and S. rebaudiana are Asteraceae species, the bootstrap value for both species was 100%.

However, it can cause serious health problems due to its carcinogenicity and neurotoxicity. Therefore, natural bioflocculants are used to treat wastewater without harming humans and the environment. Natural flocculants are non-toxic, environmentally friendly and capable of flotation even at low concentrations. This article also discusses the classification, functions, mechanisms and applications of flocculants. Applications of natural flocculants and flocculation efficiency in the treatment of industrial wastes such as food, heavy metal and dyeing are discussed. Future studies will use methods to understand how agricultural and food wastes are used for cost-effective bioflocculant production.

This research estimated and compared the ability of few common flavonoids to re-activate TRAIL-induced apoptosis by blocking Bcl-2 protein. Studies were carried out to understand the interaction between binding energy of the Flavonoids with Bcl-2 protein in cancer cells. The pharmacokinetic and toxicity profiling was performed to study the potency of the flavonoids as a lead candidate. Baicalein was selected as lead molecule because of its lower binding energy and its ability to increase Mitochondrial Membrane Potential as studied from its ADME properties.

Aim: To investigate the effect of nisin ZP (NZP) when dissolved in four different solvents on the viability of MG63 osteosarcoma cells. Materials and methods: MG-63 cells were incubated overnight at 37°C, 5% CO2 and treated with increasing concentration of dimethyl sulfoxide (DMSO), methanol and acetic acid to observe the cytotoxic effects of these chemicals onto the cells via MTS assay. NZP was then dissolved in distilled water and the three solvents in increasing concentrations and applied to the cultured cells. Cell viability and morphology were documented. Results: Acetic acid, DMSO and methanol at 0.05% maintained more than 90% viability of MG-63. NZP precipitated at higher concentrations (≥ 800µg/ml) when dissolved in DMSO, methanol and distilled water which interfered with the measurement of formazan density in the cell viability assay. Increasing doses of NZP in 0.05% acetic acid showed the least interference with the desirable reduction of the cancer cell viability. Microscopically, as concentration of NZP increases, cell shrinkage and apoptotic bodies were more visible. In addition, brown precipitates were abundantly observed. Conclusion: Acetic acid provides the optimal solubility of NZP and the best solvent to use in experiments involving MG-63 cells.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75536617","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 occurrence of twinning birth in cattle has been found in Indonesia both on beef and dairy breeds, however, the frequency is very low. This study aimed to identify the genetic variation of the candidate loci of Bovine chromosome 10 (BTA10) to control twinning in beef and dairy cattle in Indonesia. At least 57 historical twin births of both beef and dairy breeds across Central Java with the highest twins in cattle, were identified in 2017 during the dry season. The ratio of twin calves was relatively similar between female and male calves. Male twins showed the highest number (37.8%), while freemartin heifers were also highly born (28.9%) among twin births. Forty-nine heads out of 152 heads were sequenced on the partial regions in BTA10 that were highly homologous with the ovulation rate gene. DNA sequences polymorphism was identified at three regions in the BTA10 among twins of Simmental, Ongole, Limousin, Simmental-Ongole, and Holstein Friesian cattle. A significant association was not revealed between identified SNP and twinning birth potential in all breeds. Notably, one SNP (A/G) at 410 nucleotides in the consensus sequence of BTA10-2 appeared to be highly significantly associated with twinning birth potential in beef cattle of the Simmental. Taken together, this SNP would be a potential genetic marker for early selection of twinning birth which is promising for dramatic improvement of beef cattle production.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79803760","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}

Out of the 45 isolates, 44 (97.8%) were found to be resistant to at least one antibiotic, 38 (84.4%) resistant to metronidazole (MTZ), and all were sensitive to amoxicillin (AMX) and tetracycline (TET). Sixty percent of the isolated strains were resistant to 3-6 antibiotics; among them, multiple drug resistance (MDR) strains presented twenty percent resistance to more than two classes of antibiotics. Eleven strains (24.4%) carried two mutations associated with CLA and LFX but only nine of them were dual resistant to CLA and LFX, and twenty-four (53.3%) carried either CLA or LFX mutation.

In addition to molecular docking, we perform molecular dynamic simulation and found stearate relatively stable to bind Nsp3. The RMSD of complex protein to stearate was stable below 1 nm over 20 ns simulation. This could be caused by hydrogen bonds between stearate and Nsp3 protein, where average of hydrogen bond is 1.2, and recorded to be higher during the last 10 ns with an average of 1.5.

However, determination of the predominant isomer in adipose tissue remains obscure. The goal of this study is to identify the AMPK isomers present in human subcutaneous adipose tissues comparing between lean and overweight/obese subjects. Total RNA from post-mortem subcutaneous adipose tissue was extracted and its quantity and integrity were evaluated using a bioanalyzer before being reverse transcribed to cDNA. Then, by using SYBR-green as a fluorophore detection, quantitative real-time PCR was performed. The relative expression of each target gene was calculated using the comparative 2-∆∆Ct method, and the expression levels of target genes were normalized to that of GAPDH, RPLP0, and HPRT1. Mean differences of AMPK subunits mRNA level for both lean and overweight/obese subjects were determined by Mann-Whitney for two-sample comparisons using SPSS 26.0 (SPSS Inc., USA). This study revealed that in overweight/obese subjects, the gene expression of α1-AMPK was upregulated (2.5-fold) whilst α2-AMPK was downregulated (0.5-fold) when compared to lean controls (p=0.044). There were no differences observed between the β and γ subunits in both lean and overweight/obese subjects. Findings from this study suggests that α1- and α2-AMPK gene expression plays an important role in overweight/obese subjects. Future studies to explore the AMPK gene expressions in visceral adipose tissue and among underweight subjects would further close this knowledge gap.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91348644","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}
