Aims: This study aims to investigate the role of rhamnolipid in inhibiting biofilm production and gene expression of five adherence genes fimB - fimH in Escherichia coli. Methodology and results: Escherichia coli was isolated from urine and burns at a percentage of 20% for each of them. In contrast, the isolation percentage from sputum was 10%. It was also isolated from stool (control) at 100%. Using Congo red agar method (CRA), 36 E. coli isolates were tested, and it was found that 50% were strong biofilm producers and 2.8% were moderate biofilm producer where 19.4% was weak biofilm producer, and 27.8% were non-biofilm producers. However, in the MTP method, it was found that 27.8% were strong biofilm producers, 25% were moderate biofilm producers, 19.4% were weak biofilm producers where 27.8% were non-biofilm producers. 10 isolates of Pseudomonas aeruginosa produced rhamnolipid. Rhamnolipid appeared in two spots using TLC technique related to dirhamnolipid and mono-rhamnolipid. Subminimum inhibition concentration (sub-MIC) of rhamnolipid for E. coli appeared between 1250-78.125 µg/mL. Conclusion, significance and impact of study: Real-time PCR was used to detect the ability of rhamnolipid on the expression of the adherence genes fimB, fimC, fimE, fimI and fimH. Escherichia coli No 5RE32 shows an increase in expression after exposure to sub-MIC of rhamnolipid at the concentration of 1250 µg/mL. The most affected gene was fimC, followed by fimH, with the same effect on fimB and fimI, and less on fimE. Keywords: Biofilm, E. coli, real-time PCR, rhamnolipid

This narrative study seeks to investigate the interaction between Clostridium perfringens and ECM proteins present in bones and cartilage, which are important factors in the body’s movement in individual division, causing the decomposition of dead tissues in the body into necessary materials for their nutrition, which reliably prevents innate and acquired immune responses, thus providing amino acids and other nutrients necessary for the bacteria to flourish and multiply. Recently, live and laboratory experiments have found that bacteria produce collagenase and stimulate the decomposition of collagen present in bone and cartilage tissues which may cause them to lose their natural structure and physiological functions. Finally, it has been shown that the importance of the research has reached the effect of the pathogen on the degradation of collagen in bones and cartilage

The process of converting nitrogen into ammonia in the form of a compound is referred to as biological nitrogen fixation. This process is accomplished by various types of nitrogen-fixing bacteria. In this process, atmospheric dinitrogen is enzymatically converted into ammonia by nitrogen-fixing microorganisms. These nitrogen-fixing bacteria are broadly classified into two groups: symbiotic nitrogen-fixing bacteria and nonsymbiotic nitrogen-fixing bacteria. Within the microbial cells, ammonia is used for the maintenance and development of the bacterial cells. These microorganisms produce several enzymes, proteins, and cofactors that are essential for the functioning of the key enzyme nitrogenase. This enzyme is capable of reducing inert nitrogen molecules to ammonia. The entire process involves the electron transport chain within the bacterial cell. Two of the many diverse genera of rhizobia, Rhizobium and Bradyrhizobium, are α- proteobacterial diazottrophic families that form root nodules through the interaction of symbiotic genes. The nitrogen-fixing symbionts of actinophytes are symbiotic rhizobia of the genera Mesorhizobium, Sinorhizobium and Bradyrhizobium, such as Azorhizobium. The genera Frankia and Discorrhizobium provide drought-resistant forage roots in non-legume actinophytes such as alder and myrica woodlands. Frankia actinophytes have the ability to live as sugar and cellulose decomposers in addition to being symbiotic with actinophytes. Integrating nitrogen-fixing bacteria into integrated disease management can lead to significant plant growth. Research involving the application of biofertilizers in a variety of crops is at an interactive level. Nitrogen-fixing bacteria can fix nitrogen from the air into the root zone under both free and bonded nitrogen fixation. In some cases, co-inoculation of mycorrhizal spores together with nitrogen-fixing microorganisms and Azospirillum strains has shown improvement in plant health. Nitrogenfixing bacteria can improve the structure and fertility of soils that have been degraded for various reasons. Therefore, nitrogen-fixing bacteria have the potential to be used in environmental remediation processes to treat wastewater, human and animal waste, or overcome other disinfection caused by industrial pollutants. In environmental nitrogen cycles, the application of nitrogen-fixing bacteria can provide opportunities for the accumulation and preservation of organic matter through different particle sizes. However, it is necessary to identify nitrogen-fixing bacteria endemic to different ecosystems and study the potential biochemical cycles of nitrogen in different sized mineral components. In addition, the efficiency rates of chemical remediation should be compared due to potential problems with the development of concentrations of these microorganisms in environmental restoration or bioremediation processes over large areas. There is hope for the positive development of strategies to eliminate harmful metals in soil and restore potential management profits under the green economy policy, with the preferential use of extreme organisms living within soil elements, which will contribute to different strategies for the use of nitrogen fertilizers in agriculture.

Many environment have limited bioavailable iron, which leads to a variety of response strategies aimed at maintaining iron homeostasis Microorganisms, in particular, have specialized iron uptake system and frequently coordinate the synthesis and up take of iron with other cellular function like motility and biofilm formation. Microorganism produce and release low–molecular–weight compounds called siderophores in to the extracellular medium. these chelators have a high affinity and selectivity for Fe (III), making them a crucial component of an iron acquisition strategy. Sidrophores are often characterized as low–molecular–mass substances that chelate iron. Siderophores are more attracted to ferric iron than the majority of proteins. Through their role as iron-complexing ligands, they scavenge available iron and create a very stable ferric ion complex. This complex is know as Fe-siderophores complex or siderophores–iron ion complex. even if the precursor iron is present below the solubility limit, these siderophores–iron complex can stay in solution because they more soluble. Bacteria siderophres will be classified according to their chemical structure, including hydroxycarboxylates, hydroxamic acids, mixed ligands/hydroxamic acids, catecholates/metabolites, and keto acids/chelated metabolites, as well as their source, including surface-associated chelators on the bacterial envelope and released chelators. Example of siderophores Enterobactin it synthesized by Enterobacteriaceae and Pyoverdine produced by Pseudomonas species. bacteria siderophores have many application in several field, they have important role in bioremediation by …
