Streptomyces sennicomposti GMY01 is a bacterium with huge biotechnological potential that revealed by genome mining analysis. This research aimed to investigate the potential compounds as antiplasmodial and the antiSARS-CoV-2 from the S. sennicomposti GMY01 using targeted metabolomic and in silico molecular docking. The crude extract was obtained by extraction of supernatant from fermentation product of the S. sennicomposti GMY01. The secondary metabolite profiling was obtained by using ultra-high-performance liquid chromatography (UHPLC) coupled to targeted high-performance mass spectrometry (HRMS) based on genome mining data of whole genome sequence (WGS). In silico molecular docking was performed on important target protein of P. falciparum i.e. glutathione reductase (PfGR), lactate dehydrogenase (PfLDH), phosphoethanolamine methyltransferase (Pfpmt), erythrocyte membrane protein 1 (PfEMP1) and glutathione-S-transferase (PfGST); and of SARS-CoV-2 proteins i.e. protease domain, spike glycoprotein, receptor-binding domain angiotensin-converting enzyme 2 (RBD-ACE2), 3-chymotrypsin-like protease (3CLpro), and RNA-dependent RNA polymerase (RdRp). One compound from S. sennicomposti GMY01 extract, albaflavenone was confirmed by targeted LC-HRMS. On molecular docking analysis, albaflavenone showed higher affinity than chloroquine as antiplasmodial drug and exhibited same affinity to remdesivir as antiSARS-CoV-2. Stertomyces sennicomposti GMY01 has promising biotechnological potential for drug development as antiplasmodial and anti-SARS-CoV-2 agent. Further study is needed, especially regarding in vitro testing of albaflavenone as antiplasmodial and antiSARS-CoV2.

Andisols has relatively low phosphorus availability due to its adsorption by allophane. Phosphate solubilizing bacteria (PSB) increases the availability of P via release of adsorpted-P. The aims of this research were to determine: 1) anorganicP solubilization, 2) organic-P mineralization, 3) blocking of Andisols adsorption site, and 4) effective PSB inoculant. The research was arranged in completely randomized design, with PSB inoculant as treatment. Variables observed were solubleP, mineralize-P, adsorpted-P, pH, total acidity, PSB population, phosphatase and phythase activity, relative surface charge, and maize’s growth component. The result showed that PSB inoculation increased soluble-P from 30 to between 150 and 195 ppm P, increased mineralize-P from 23.7 to between 63.6 and 91.7 ppm P, and decreased P-adsorption from 95 to between 36 and 13%. PSB inoculation decreased the Andisols pH, increased the total acidity, PSB population, the phosphatase and phytase activity, and PSB had relatively high of relative surface charge (69%). The PSB inoculation increased maize P absorption in the range of 70 and 75 mg P plant-1, and increased relative agronomic effectiveness (RAE )between 145 and 150%. Liquid and solid PSB inoculant had no different effect in increasing maize growth. Keywords: Andisol, P release, phosphate solubilizing bacteria, phosphatase, phytase

High resistance to chloroquine in most malaria-endemic area in the world leads to the need for new antimalaria drugs. Marine bacterium Streptomyces is the source for potential new antimalarial molecules. This research aimed to investigate antiplasmodial activity of marine-derived of Streptomyces sp. GMY01 and to identify potential active compounds using genome mining study. In vitro antiplasmodial activity assays using flow cytometry method showed that the ethyl acetate extract of this bacterium had high antiplasmodial activity (IC50 value of 1.183 µg/mL) on Plasmodium falciparum FCR3. Genome mining analysis of whole-genome sequences using antiSMASH 6.0 beta version revealed that Streptomyces sp. GMY01 had 28 biosynthetic gene clusters (BGCs), including the genes encoding polyketide synthase, non-ribosomal peptide synthetase, terpene, lanthipeptide, bacteriocin, butyrolactone, ectoin, siderophore, and others. The known BGCs were predicted to be involved in the production of known compounds from gene clusters ranged from 5 to 100% similarity. Ongoing purification and elucidation of the structures will allow identification of the active compounds produced by marine-derived Streptomyces sp. GMY01.

Utilization of glycerol by lipase producing bacteria offers great benefits for fat and oil waste degradation and waterwaste treatment. Nevertheless, there have been lack of reports about the availability of non-pathogenic, lipase producing bacteria, which could naturally degrade glycerol produced from the lipolysis process by lipase. This study reported a newly identified species of rhizobacteria, Alcaligenes javaensis JG3, which is not only able to produce high level of lipase, but also able to degrade glycerol molecules. Identification of strain JG3 was carried out using SEM (Scanning Electron Microscope), BD Phoenix 100 Automated Microbiology System and 16S rRNA gene analysis to determine its taxonomy status. The ability of the strain to metabolize glycerol was investigated both genotypically and phenotypically using degenerate PCR and a glycerol minimal medium. Identification test results showed that strain JG3 belongs to genus Alcaligenes, with the closest relationship with A. faecalis and A. aquatilis (96% nucleotide similarity maximum). Degenerate PCR resulted in a 248-bp sequence showing 93% similarity with glpK of Candidatus Sodalis pierantonius SOPE, a key gene involved in glycerol metabolism. In vitro glycerol utilization test result showed that Alcaligenes sp. JG3 was able to grow on glycerol aerobically, but not anaerobically. It is concluded that Alcaligenes sp. JG3 possesses genes coding for glycerol metabolism and this trait is phenotypically expressed, thus making the strain potential to be used as an effective fat and oil biodegrader.

Klebsiella sp. GMD08 is a bacterium capable of dissolving insoluble inorganic phosphate into soluble phosphate ions through its organic acid production. Transposon is a genetic element commonly used to generate mutants through mutagenesis, and thus can be used to identify genetic functions involved in phosphate-solubilizing mechanisms. This research was conducted to identify the genes of Klebsiella sp. GMD08 involved in phosphate solubilization through sequence detection obtained from a hyper-solubilizing phosphate mutant library. Mutation was carried out by inserting a mini-Tn5 transposon hosted in Escherichia coli S17-1/λpir [pBSL202] into the chromosome of Klebsiella sp. GMD08 using the filter mating conjugation method. Transconjugant mutant candidates were then qualitatively and quantitatively analyzed for their ability to dissolve tricalcium phosphate [Ca₃(PO₄)₂] using Pikovskaya medium. The organic acid profiles of the transconjugant mutants were detected using High-Performance Liquid Chromatography (HPLC). Suspected genes involved in phosphate solubilization were identified through sequencing of transposon insertion sites. Nucleotide BLAST was used to determine nucleotide sequence similarity with the database. The results showed that PB116 and PB122 were the two main transconjugant mutants obtained from transposon mutagenesis with higher tricalcium phosphate-dissolving ability. Gluconic acid was identified as the main organic acid produced by Klebsiella sp. GMD08 in its phosphate-solubilizing mechanism. Furthermore, the arginine repressor (ArgR) and malate dehydrogenase (mdh) genes were found to be involved in the phosphate-solubilizing mechanism of Klebsiella sp. GMD08.
