Abstract

The bioremediation technique is an effort to remove the heavy metal Pb in samples of Citarum river water. High concentrations of heavy metals harm the environment, so Pb metal-reducing bacteria are needed as a pollution solution. Bioremediation uses bacteria. Bacteria are identified by molecular methods, namely sequencing analysis techniques, because they are more accurate. To determine the nucleotide sequence of Pb metal-reducing bacteria isolates and which bacterial species can reduce Pb metal. The methodology used is primary data collection, namely conducting research directly, namely the stages of bacterial purification through gram staining techniques, pure colonies, then proceeding to the DNA isolation stage. The isolated DNA is then electrophoresed. The electrophoresis results are then purified and proceed to the sequencing stage. The feasibility test results were to obtain pure DNA from the reducing bacteria. The next step was PCR amplification of the 16S rRNA gene of Pb-reducing bacteria. The research results started at the DNA isolation stage and obtained a purity of 1.80. The PCR results were in the form of amplification of the 16S rRNA gene of Pb-reducing bacteria. Electrophoresis obtained the results of DNA bands measuring ± 1400 bp—phylogenetic tree analysis with 99.60% relatedness to Bacillus cereus, which can reduce Pb. Bacillus cereus species can carry out detoxification mechanisms against the toxic effects of Pb metals, such as—biosorption, bioaccumulation, reduction, solubilization, precipitation (formation of extracellular complexes), and methylation.

Abstract

Dental plaque plays an important role in causing dental caries. In plaque formation, gram-positive coccus bacteria are found, one of which is Streptococcus mutans which can secrete toxins so that tooth cells are damaged. Dental plaque or dental caries can be controlled in number by controlling plaque with antimicrobial agents such as mouthwash. However, the continuous use of antimicrobials can cause side effects for users, including hypersensitivity reactions and resistance, so it is necessary to use natural ingredients as antibacterial alternatives. Therefore, this study used coriander seeds as an alternative to inhibit the growth of Streptococcus mutans bacteria. The purpose of this study was to determine the effectiveness of coriander seed extract (Coriandrum sativum L.) with varying concentrations on the growth of Streptococcus mutans bacteria. This study used the diffusion method as a bacterial test method for coriander seed extract. The concentrations tested in this study were 3%, 6% and 9%. Based on the results of the study showed that there was an inhibition zone in the test of coriander seed extract against Streptococcus mutans. At a concentration of 3% the average inhibition zone was 3.7 mm, the concentration of 6% was 4.7 mm and concentration of 9% by 6.06 mm. The results of this study concluded that coriander seed extract (Coriandrum sativum L.) was effective in inhibiting the growth of Streptococcus mutans bacteria.

Abstract

Candidiasis is an acute or chronic inflammation that causes disorders of the body's system caused by the fungus Candida albicans. Candida albicans is a common cause that does not cause disease in a person's normal immune system but can attack a person's poor system. Candidiasis can be treated with antifungal drugs, but prolonged and extensive use of antifungal drugs causes side effects. So alternative drugs are needed that can reduce these side effects. Lemongrass (Cymbopogon citratus) has pharmacological activity as an antifungal. Research Objectives: To determine the inhibition of lemongrass extract on the growth of Candida albicans in an SDA medium with concentrations of 0%, 0.2%, 0.4%, 0.6%, 0.8%, and 1%. The study used a descriptive research design. The method of testing the resistance is carried out by the good diffusion method. Lemongrass extract can inhibit the growth of Candida albicans fungus by forming an inhibition zone. At a concentration of 0% lemongrass extract, no inhibition zone was formed, a concentration of 0.2% formed an inhibitory zone of 10.5 mm, a concentration of 0.4% formed an inhibition of 6.1 mm, a concentration of 0.6% formed an inhibition zone of 14 mm, the concentration 0.8% formed an inhibition zone of 10.8 mm, a concentration of 15 formed an inhibitory zone of 27.6 mm.

Abstract

Conjunctivitis is the most common eye disease, characterized by contextual inflammation, which can be caused by bacteria. The diagnosis of conjunctivitis is established based various factors, including the patients’s medical history, onset of eye symptoms, non-ocular symptoms, previous disease history, family medical history, allergies, and physical examination of the eyes, which may include assessments of visual acuity and vision field. Some cases of conjunctivitis require laboratory examinations to confirm the diagnosis. These may include cytological examination with Giemsa staining, Chlamydia Diagnostic Test, Nucleic acid amplification tests (NAATs) or Polymerase chain reaction (PCR), and microbiological tests. Microbiological examination helps identify the bacteria responsible for conjunctivitis and aids in treatment by prescribing antibiotics to suppress the growth of the infecting bacteria. While identification tests are not routinely performed, researchers often seek to determine the specific type of bacteria causing conjunctivitis infections, which may require several laboratory tests. Bacterial virulence plays a significant role, with genetic mutations potentially leading to severe infections of varying severity. Virulence genes encode proteins that express pathogenic properties. The species responsible for conjunctivitis can be definitively identified definitively through microbiological examination, utilizing methods such as the 16S Ribosomal RNA Sequencing (rRNA) technique, known for its accuracy and speed. This study aims to analyze the results of rRNA sequencing in cases of acute bacterial conjunctivitis caused by 16S rRNA genotyping. The research employed an exploratory metholodolot, with the results analyzed using the The Basic Local Alignment Search Tool (BLAST) tracking program database on the National Center for Biotechnology Information (NCBI) website. The findings revealed that Sphingomonas paucimobilis encoded the 16S rRNA using Universal Primary 27 F and 1492 R, obtained in a sequence size of 1351bp. The isolate demonstrated similarities to Sphingomonas paucimobilis.
