Abstract:
Lemon (Citrus limon) is the most commonly grown tree fruit in the world. The fresh lemons were collected from the local market of Kathmandu, Nepal. Hexane and methanol extracts of plant material i.e. lemon peel were screened for the analysis of the presence of phytochemicals as well as their antibacterial activity. Methanol extract of lemon peel showed the maximum positive phytochemical test with the presence of alkaloids, flavonoids, polyphenols, terpenoids, glycosides, saponin, tannins etc. The essential oil was obtained by steam distillation from fresh peels of lemon using the Clevenger app

Abstract:
One of the world’s most sustainable solutions is to replace fossil-based polymers with biopolymers. The production of xanthan gum can be optimized using various renewable and cost-effective raw materials, which is a key focus in industrial biotechnology. Xanthan gum is a bioengineered thickening, stabilizing, and emulsifying agent. It has unique properties for use in many industries (food, biotechnology, petrochemicals, agricultural, cosmetics, wastewater treatment) and medical applications. It is tasteless, environmentally safe, non-toxic, and biodegradable. The biotechnological production of

In this work, the effect of dyes extracted through the Naviglio method (an eco-innovative solid-liquid extraction technique) was tested, which proved interesting for such an extraction. The dyes extracted from Opuntia ficus-indica (L.) Miller waste were treated to maximize the extraction of the coloring molecules. The extraction method was compared with conventional methods under the same conditions. The results showed that the extracts obtained with the different techniques, in the same extraction conditions (solvent, pH, temperature, time), were richer in the pigments for the extract obtaine
