Study of Potential Application of Cyanobacteria Leptolyngbya Valderiana in Skin Cosmeceuticals

Shraddha Ratnaparkhe — 2021-10-01

Skin is the outermost cover and first line of defense of the human body. Skin cosmeceuticals are therapeutic agents used to maintain flawless skin and prevent skin disorders. Considering the ill effects of synthetic active agents, natural metabolites are preferred for skincare. Cyanobacterium was known to produce various secondary metabolites with therapeutic potential. This study focuses on screening whole-cell extract of Leptolyngbya valderiana for skincare. Isolation and identification of cyanobacteria were made. The whole-cell extract of Leptolyngbya valderiana was studied for its metabolite profile, mainly for proteins, carbohydrate, and lipid content. Screening of whole-cell extract was carried out for its (2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)) (ABTS) radical scavenging ability and UV absorption potential. The antimicrobial effect of extracts was determined by agar cup and minimum inhibitory concentration (MIC) method using salicylic acid as a standard. Skin whitening potential was determined using tyrosinase inhibition assay. Leptolyngbya valderiana was isolated from the tree bark and selected for further study. The extract of Leptolyngbya valderiana was found to have 25.22% proteins, 36.65 % carbohydrates and 35.97% lipids. The extract was found to have antioxidant potential with 96.55% ABTS radical scavenging potential. Antimicrobial potency of the extract against Staphylococcus aureus ATCC 6538, Propionibacterium acne MTCC 1351, Candida albicans ATCC 10231 was equivalent to salicylic acid. The test extract was found to inhibit the tyrosinase enzyme by 43.46%. The test extract is rich in proteins, carbohydrates, and lipids. The extract has significant antioxidant potential, antimicrobial efficiency, ability to absorb ultraviolet B and ultraviolet A region, tyrosinase inhibition potential indicative photoprotective, and skin whitening potential. The isolate Leptolyngbya valderiana has a promising potential for skin cosmeceuticals.

Sensor Applications in Analysis of Drugs and Formulations

Biosensors are currently widely used in biomedical diagnostics, as well as point-of-care assessment of therapy and disease advancement, environmental sensing, food safety, drug development, forensics, and biomedical research. Biosensors may be developed using several different approaches. Due to the growing requirement for efficient and low-cost analytical methods, biosensors have gained increasing attention for application in the quality analysis of pharmaceuticals and other pharmaceutically relevant analytes. Biosensors enable the analysis of active ingredients in pharmaceutical formulations as well as the determination of degraded products and intermediates in biological matrices. The current study discusses several types of biosensors and their applications in drug analysis and formulations.

Geographical Survey and Genetic Variation Studies of Few Chilly Varieties Collected from Different Regions of Karnataka, India

Chillies are widely used throughout the world in the form of spice and are also used in making beverages and medicines. They are rich in vitamins, especially in vitamin A and C. Chillies contain lots of minerals like potassium, magnesium, and iron. They have been employed for pain relief as they are known to inhibit pain messengers and hence their extracts are used to alleviate the pain of arthritis, headaches, burns, and neuralgia. It is also claimed that they have the power to boost the immune system and lower cholesterol. They are also helpful in getting rid of gut parasites. In this regard we attempted to do a geographical survey about the chilly varieties and chilly growing states in India. We collected the local varieties of chillies available in Karnataka and performed genetic variation studies to understand their relationship at the genetic level. PCR analysis was done using the selected random amplified polymorphic DNA (RAPD) marker to identify the polymorphic loci between the genotypes taken. DNA Barcoding was done to validate the species using basic local alignment search tool (BLAST) and Clustal Omega, further dendrogram was constructed which guide the joining linkage rule of unweighted pair group average (UPGMA) and the genetic distance to compute from matrix table. The results obtained highlight the relationship between species of Capsicum annum, Capsicum frutescens which are closely related followed by Capsicum pubescens and Capsicum baccatum providing knowledge about its application in genetics and plant breeding in developing efficient hybrid variety.
