Abstract

Exposure to sunlight (UV radiation) can harm the skin, leading to cancer and tissue damage. The body’s natural defense involves activating hormones that stimulate melanin synthesis to reduce cellular damage. Moringa oleifera Lam. leaves, rich in flavonoids and phenolic compounds, are promising UV-protection agents. This study assessed the efficacy of nanoemulgel formulations containing M. oleifera leaf extract through in vitro and in vivo assays. Twenty-five rats were divided into five groups, including formulations with 2%, 3%, and 4% M. oleifera extract, a negative control, and a positive control with Azarine Sunscreen Gel SPF 45. The nanoemulsions had appropriate size and quality, with the highest SPF observed at 4% concentration (7.95±0.06). According to FDA classification, these formulations fall within the 'extra' SPF category (6<SPF<8). However, melanin scores in the nanoemulgel groups were comparable to the untreated control, and the 4% concentration (44.4±16.3) did not match the protection provided by commercial sunscreen (10.0±1.58). These findings suggest M. oleifera has potential for photoprotection, but further optimization is needed.

Abstract

Cellulolytic bacteria are bacteria that produce cellulase enzymes capable of degrading cellulose substrates. This study aimed to isolate and identify as well as measure the cellulase enzyme activity of cellulolytic bacteria isolated from the digestive tract of swans (Cygnus olor) in Mataram. The bacteria were isolated using de Man Rogosa Sharpe (MRS) selective media with the spread plate method. Then, the extracellular enzyme activity test was conducted by growing selected pure isolates on 1% Carboxy Methyl Cellulose (CMC 1%) media, followed by pouring 0.1% congo red solution and rinsing with 1M NaCl solution to determine cellulolytic activity (cellulolytic potential indicated by the appearance of a clear zone around the colony) and measuring the cellulolytic index. The bacterial isolation results obtained 4 isolates with the potential to support fiber degradation in animal feed. The highest cellulolytic index was produced by the isolate coded S1, reaching 34.5 mm, while the lowest cellulolytic index was produced by 2 isolates coded J21 and I2, reaching 18.8 mm.
