Objective:The present review highlights the advantages of using natural colorant over the synthetic one. We have discussed the fermentation parameters that can enhance the productivity of Monascus pigment on agricultural wastes.Background: Food industry is looking for natural colours because these can enhance the esthetic value, attractiveness, and acceptability of food while remaining nontoxic. Many synthetic food colours (Azorubine Carmoisine, quinoline) have been prohibited due to their toxicity and carcinogenicity. Increasing consumer awareness towards the food safety has forced the manufacturing industries to look for suitable alternatives. In addition to safety, natural colorants have been found to have nutritional and therapeutic significance. Among the natural colorants, microbial pigments can be considered as a viable option because of scalability, easier production, no seasonal dependence, cheaper raw materials and easier extraction. Fungi such as Monascus have a long history of safety and therefore can be used for production of biopigments.
Method:The present review summarizes the predicted biosynthetic pathways and pigment gene clusters in Monascus purpureus.
Results:The challenges faced during the pilot-scale production of Monascus biopigment and taming it by us of low-cost agro-industrial substrates for solid state fermentation has been suggested.
Conclusion:Keeping in mind, therapeutic properties of Monascus pigments and their derivatives, they have huge potential for industrial and pharmaceutical application.
Alzheimer's disease (AD) is the leading type of dementia in aging people and is a progressive condition that causes neurodegeneration, resulting in confusion, memory loss, and deterioration of mental functions. AD happens because of abnormal twisting of the microtubule tau protein in neurons into a tangled neurofibrillary structure.
The human gastrointestinal (GI) tract has been bestowed with the most difficult task of protecting the underlying biological compartments from the resident commensal flora and the potential pathogens in transit through the GI tract. It has a unique environment in which several defence tactics are at play while maintaining homeostasis and health. The GI tract shows myriad number of environmental extremes, which includes pH variations, anaerobic conditions, nutrient limitations, elevated osmolarity etc., which puts a check to colonization and growth of nonfriendly microbial strains. The GI tract acts as a highly selective barrier/platform for ingested food and is the primary playground for balance between the resident and uninvited organisms. This review focuses on antimicrobial defense mechanisms of different sections of human GI tract. In addition, the protective mechanisms used by microbes to combat the human GI defence systems are also discussed. The ability to survive this innate defence mechanism determines the capability of probiotic or pathogen strains to confer health benefits or induce clinical events respectively.
Biotherapeutics is a rapidly growing segment of the entire pharmaceutical industry that constitutes approximately one-quarter of ongoing new drug endorsements. Monoclonal antibodies are a major part of these endorsements every year (mAbs). MAbs' non-clinical pharmacology and toxicology research compare with substance components during progression, since these biotherapeutics are extracted from an organic source, and to inspire a pharmacological reaction, the creature models must also have similar epitopes (focuses) as individuals. Biotherapeutic items (BTPs) are the quickest developing drugs in the pharmaceutical market. Despite their clinical achievement, the immunogenicity of BTPs keeps on being a significant concern. The subcutaneous (SC) course is to cultivate a passion for the organisation of biotherapeutics. Both monoclonal antibodies and various biotherapeutics are discussed. Medicine has been disrupted by biotherapeutic drugs (BPs), altering the way we treat a few processes. Comparative BPs (SBPs) are discussed here, also called biosimilars, including the assembly process and administrative viewpoints used. Monoclonal antibodies can apply synergistic antitumour impacts in blend with other immunomodulatory approaches, for example, chemotherapy, radiotherapy, directed treatment specialists, immunisations, or different immunomodulators. Probiotics have gotten profoundly perceived as enhancements for people and specifically for creatures given their gainful result on wellbeing improvement and prosperity support.
In the present study, Monascus red biopigment produced by solid-state fermentation was evaluated for its anti-microbial and antioxidative potential. The antibacterial activity through Scanning Electron Microscopy against Bacillus cereus, Escherichia coli, and Staphylococcus aureus was found to show morphological damage in some cells, as evidenced by the outflow of cell contents, deep craters, burst cells, and cell death at concentration of 200 µg/ml of biopigment. Moreover, antibacterial activity through agar well diffusion method against Bacillus cereus, Staphylococcus aureus, Klebsiella pneumonia and Pseudomonas aeruginosa was in range of 2-6 mm by varying concentration of biopigment from 1 to 20 mg/ml.Next, the antifungal activity of the extracted biopigment was in the range of 2-9 mm for Aspergillus flavus, Fusarium oxysporum and Alternaria alternata. In addition, antioxidant efficacy of red biopigment through DPPH, ABTS and FRAP assay results was found to show 59.69 %, 91.1 %, and 15.22 % free radical scavenging activity. The results of this study revealed that red biopigment has potential to modulate the antimicrobial and antioxidative activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
