The present study reports the production of bacterial cellulose (BC) membranes using for the development of transdermal wound healing patches. BC-based transdermal patches were developed by impregnating varied concentrations of antibiotic mupirocin and characterized by SEM, FTIR, TGA, and DSC to study the interaction of BC with antibiotic. Developed patches were evaluated for antimicrobial activity, drug release study, efficacy, and acute dermal toxicity studies.

Antimicrobial resistance (AMR) is one of the most challenging problems and is responsible for millions of deaths every year. We therefore urgently require new chemical entities with novel mechanisms of action. Phytocannabinoids have been adequately reported for the antimicrobial effect but not seriously pursued because of either stringent regulatory issues or poor drug-like properties.

The main goal of this study was to provide possible alternative production medium containing xylose enriched spent lemongrass hydrolysate with glycerol as a feedstock and corn gluten meal as a nitrogen source for their ability to support the cell growth of the Streptomyces clavuligerus MTCC 1142 for the production of clavulanic acid. The xylose was extracted from spent lemongrass by using 0.25% dilute nitric acid and further partial purification of acid spent hydrolysate was performed using ion exchange resin.

Corn gluten meal (CGM) which is a byproduct of corn wet milling is mainly used in animal and poultry feed. Due to its high protein content in CGM, it has been utilized for the extraction of zein protein which is the main hydrophobic protein present in the corn. The extracted zein protein was used along with bacterial cellulose that is highly pure, biocompatible, biodegradable, and generally regarded as safe for the preparation of composites that have better surface properties and applications.

UDP-N-acetylglucosamine enolpyruvyl transferase (MurA) is an essential cytosolic enzyme in the biosynthesis of peptidoglycan. It becomes a potential bacterial target for screening promising antibacterial compounds as it is associated with the early phases of peptidoglycan production. MurA enzyme is conserved and necessary for bacterial viability with no mammalian homolog, which is a well-proven therapeutic research target.

Annually, a huge amount of waste is generated by the industries that use agricultural biomass. Researchers have looked into employing this cheap and renewable agro-biomass as a substrate for enzyme production via fermentation processes to meet the ever-increasing worldwide need. Although there are a number of sources for enzyme extraction, microbial sources have dominated industrial sectors due to their easy availability and rapid growth.

Unlabelled: Antibiotic resistance is one of the biggest challenges that is escalating and affecting humanity across the globe. To overcome this increasing burden of resistance, discovering novel hits by targeting the enzymes involved in peptidoglycan (murein) biosynthesis has always been considered better in antimicrobial drug discovery. UDP-N-acetylglucosamine enolpyruvyl transferase (MurA) enzyme has been identified as essential for survival and catalyzes the early-stage step in bacterial cell wall synthesis.

Background: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 pandemic, has infected more than 179 million people worldwide. Testing of infected individuals is crucial for identification and isolation, thereby preventing further spread of the disease. Presently, Taqman™ Reverse Transcription Real Time PCR is considered gold standard, and is the most common technique used for molecular testing of COVID-19, though it requires sophisticated equipments, expertise and is also relatively expensive.

Mono alkyl fatty acid ester or methyl ethyl esters (biodiesel) are the promising alternative for fossil fuel or petroleum derived diesel with similar properties and could reduce the carbon foot print and the greenhouse gas emissions. Biodiesel can be produced from renewable and sustainable feedstocks like plant derived oils, and it is biodegradable and non-toxic to the ecosystem. The process for the biodiesel production is either through traditional chemical catalysts (Acid or Alkali Transesterification) or enzyme mediated transesterification, but as enzymes are natural catalysts with environmentally friendly working conditions, the process with enzymes are proposed to overcome the drawbacks of chemical synthesis.

Microbial secondary metabolites (SMs) are the intermediate or the product of metabolism produced during fermentation process. SMs are produced during stationary phase and play a major role in competition, antagonism and self defence mechanisms. These metabolites finds application in the pharmaceuticals, food, cosmetics etc.

Different natural aromatic/heterocyclic l-amino acids were biotransformed into aryl/heteroaryl ethanol metabolites oxidative deamination, decarboxylation and reduction cascades using live baker's yeast cells producing intracellular human CYP2D6 enzyme. Among the three yeast strains expressing 3 different CYP2D6 variants, CYP2D6(2) ( CYP2D6 wild-type) provided the best result under neutral pH conditions at RT. We have successfully converted six natural amino acids into their corresponding alcohols, having one carbon atom less, with moderate yields.

It is imperative that promising bacterial cellulose-producing bacteria mainly belongs to genera Acetobacter (acid-producing bacteria). In order to screen cellulose-producing Acetobacter, the isolated cultures from vinegar/rotten fruits were inoculated in Hestrin-Schramm (HS) medium containing ethanol and CaCO. After the desired incubation, the positive cultures form a zone, which is observed around the bacterial growth, resulted from the solubilization of CaCO by acetic acid produced from the oxidation of ethanol during fermentation.

l-Asparaginase-producing microbes are conventionally screened on phenol red l-asparagine-containing plates. However, sometimes the contrast of the zone obtained (between yellow and pink) is not very sharp and distinct. In the present investigation, an improved method for screening of the microorganisms producing extracellular l-asparaginase is reported wherein bromothymol blue (BTB) is incorporated as pH indicator in l-asparagine-containing medium instead of phenol red.
