The enzymatic and acid hydrolysis have converted eight new starches into a range of chain lengths mainly including glucose, maltose, and maltodextrins as observed on TLC plates, irrespective to the starch variety and treatment. Results of the enzymatic hydrolysis have highlighted the possibility of the use of V4 and V64, which can be labelled as "dietary fibres", to enhance the organoleptic qualities of foods and for fibre fortification of low-calorie products. Concerning V66 and V69, they have much relevant in food, textile and pharmaceutical applications. The acid hydrolysis showed that V73 is the best starch in the chemical industry for making environment-friendly products such as plastics. Because starch is a natural component that degrade quickly in normal composting condition, the whole studied starches could be advised for various utilizations in the food, textile, paper, biofuel, pharmaceutical and plastic industries for sustainable development.

Biocatalysis provides access to synthetically challenging molecules and commercially and pharmaceutically relevant natural product analogs while adhering to principles of green chemistry. Cytochromes P450 (P450s) are amongst the most superlative and versatile oxidative enzymes found in nature and are desired regio- and stereoselective biocatalysts, particularly for structurally complex hydrocarbon skeletons. We used 10 genome-sequenced Streptomyces strains, selected based on their preponderance of P450s, to biotransform the bioactive diterpenoid abietic acid.

Wearable sensors have broad application potential in motion assessment, health monitoring, and medical diagnosis. However, relying on a specialized instrument for power supply and signal reading makes sensors unsuitable for on-site detection. To solve this problem, a reusable self-powered electrochromic sensor patch based on enzymatic biofuel cells were constructed to realize the on-site visualized monitoring.

Rapid, quantitative, and sensitive detection of viral oligonucleotides can help to diagnose the infection before symptoms occur, monitor disease progression, and identify viral subtypes. A one-pot, simple, rapid hairpin-mediated nicking enzymatic signal amplification (HNESA) method was previously developed for nucleic acids detection. In the present work, this method was applied for the detection of SARS-CoV-2 RNA by designing an assistant probe (AP) that contains the complementary sequence for the target, the sequence of hybridization with the loop region of the molecular beacon (MB), and the recognition site of the nicking endonuclease Nt.

Endophytic actinomycetes are potential sources of novel pharmaceutically active metabolites, significantly advancing natural product research. In the present investigation, secondary metabolites from two endophytic actinomycetes, Streptomyces parvulus GloL3, and Streptomyces lienomycini SK5, isolated from medicinal plant taxa, Globba marantina, and Selaginella kraussiana, exhibited broad-spectrum bioactivity. Ethyl Acetate (EA) extract of SK5 showed antimicrobial activity against nine human pathogens, including Methicillin-resistant Staphylococcus aureus (MRSA), Candida tropicalis, and C.

Bacteriophages produce endolysins at the end of the lytic cycle, which are crucial for lysing the host cells and releasing virion progeny. This lytic feature allows endolysins to act as effective antimicrobial alternatives when applied exogenously. Staphylococcal endolysins typically possess a modular structure with one or two enzymatically active N-terminal domains (EADs) and a C-terminal cell wall binding domain (CBD).
