Production and optimization of amylase enzyme using bacillus subtilis under solid state fermentation and its characterization
Abstract: This study employed solid state fermentation to maximize amylase production by Bacillus subtilis (OR578403). The research began by discovering and analyzing amylase-producing bacteria in soil samples followed with biochemical, molecular characterization. By using commercially available substrates like wheat bran, rice bran, and wheat rava were obtained from the local market and employed as solid substrates, which may influence amylase production and to be assessed. The identified organism was Bacillus subtilis, …

Characterization of Plant Growth Promoting Bacillus subtilis (VBKT5) Isolated from Vermicompost
Abstract: Vermicompost is a rich source of nutrients and beneficial soil bacteria which can promote plant growth in various ways. Ten prevalent bacterial strains were isolated from the cow dung vermicompost and assessed for growth promotion of paddy. Bacterial suspensions (3X108 CFU/ml) were individually applied to the pots planted with paddy variety and vegetative growth parameters and yield were recorded. Among the bacterial treatments, better shoot length, root length and yield …

Experimental Evaluation of Strength in Bacterial Concrete Mixtures
Abstract: The incorporation of bacteria into concrete, through the process of Microbiologically Induced Calcite Precipitation (MICP), offers a promising approach to enhancing the mechanical properties and durability of concrete. This research explores the effect of bacterial addition on the compressive strength, split tensile strength, flexural strength, and workability of concrete. Specifically, three bacterial strains—Bacillus megaterium, Bacillus subtilis, and Pseudomonas aeruginosa—were used in varying concentrations (10⁴, 10⁵, and 10⁶ cells/ml) and incorporated …

Production of n-Butanol from Biomass by Two Step Fermentation Process Using Staphylococcus Sciuri
Abstract: This study explores the sustainable production of n-butanol from wheat husk through a two-step bioconversion process. Wheat husk, an abundant agricultural residue, was first fermented into butyric acid using Bacillus subtilis. The resultant butyric acid was then converted into n-butanol using Staphylococcus sciuri. The process leverages biological fermentation to create value-added chemicals from lignocellulosic biomass, offering an eco-friendly alternative to petrochemical methods. Two steps fermentation process were carried to increase …

Bioremediation Potential: Discovering Naphthalene-Degrading Microbes in Iraqi Contaminated Soil
Abstract: A polycyclic aromatic hydrocarbon, napthalene is an environmental contaminant with a slow rate of disintegration. Biological treatment by microbes present in contaminated places is the most important of the several approaches applied to remove it from the environment. At depths of 5 to 10 cm, soil samples were collected from areas polluted by oil near the Al-Dora and Sheikh Omar refineries. Nutrient agar was cultured with 0.1 ml of each …

Characterization of Synthesized Heterocyclic Oxadiazole Derivatives Using Mass, UV, IR, and NMR Spectroscopy, Among other Spectroscopic Techniques: Review
Abstract: The current study synthesized and assessed 3-heteroarylazo 4-hydroxy coumarin derivatives' initial antibacterial activities in vitro against four distinct pathogenic bacterial strains, including Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli, and Staphylococcus aureus. Ampicillin, a common medication, was used to compare each compound's antibacterial properties. UV, IR, 1H NMR, mass spectroscopy, and X-ray diffraction examinations were used to analyze the compounds. By using UV–vis spectra, the solute-chromic behavior of these compounds was …

Exploring the Bioactive Potential of Himalayan Lichens: Phytochemical and Antimicrobial Profiling of Xanthoparmelia tinctina and Pyxine subcinerea Extracts
Abstract: The symbiotic association that develops between cyanobacteria, algae, and fungi results in the composite organism known as lichens, which has traits similar to those of plants but differs in its separate parent organisms. Lichens can have a variety of morphological characteristics, including foliose structures that resemble flat leaves, crustose structures that resemble flake crystals, fruticose branches that have short, leafless branches, and leprose-powder-like appearances. Due to their therapeutic potential, lichens …

Self Healing Material: An Introduction
Abstract: Self-healing materials have emerged as a transformative innovation for sustainable infrastructure and advanced applications such as wearable electronics and smart transportation systems. These materials possess the intrinsic ability to repair damage autonomously or with minimal external intervention, thereby extending service life and reducing maintenance costs. Inspired by biological systems, self-healing mechanisms are broadly classified into extrinsic approaches, such as microcapsule and vascular networks based healing, and intrinsic mechanisms involving reversible …
