Fucoxanthin is an algae-specific xanthophyll of aquatic carotenoid. It is prevalent in brown seaweed because it functions as a light-harvesting complex for algal photosynthesis and photoprotection. Its exceptional chemical structure exhibits numerous biological activities that benefit human health. Due to these valuable properties, fucoxanthin’s potential as a potent source for functional food, feed, and medicine is being explored extensively today. This article has thoroughly reviewed the availability and biosynthesis of fucoxanthin in the brown seaweed, as well as the mechanism behind it. We included the literature findings concerning the beneficial bioactivities of fucoxanthin such as antioxidant, anti-inflammatory, anti-obesity, antidiabetic, anticancer, and other potential activities. Last, an additional view on its potential as a functional food ingredient has been discussed to facilitate a broader application of fucoxanthin as a promising bioactive compound.
Lactic acid has become one of the most important chemical substances used in various sectors. Its global market demand has significantly increased in recent years, with a CAGR of 18.7% from 2019 to 2025. Fermentation has been considered the preferred method for producing high-purity lactic acid in the industry over chemical synthesis. However, the recovery and separation of lactic acid from microbial fermentation media are relatively complicated and expensive, especially in the process relating to second-generation (2G) lactic acid recovery. This article reviews the development and progress related to lactic acid separation and recovery from fermentation broth. Various aspects are discussed thoroughly, such as the mechanism of lactic acid production through fermentation, the crucial factors that influence the fermentation process, and the separation and recovery process of conventional and advanced lactic acid separation methods. This review's highlight is the recovery of lactic acid by adsorption technique using ion-exchange resins with a brief focus on the potential of in-site separation strategies alongside the important factors that influenced the lactic acid recovery process by ion exchange. Apart from that, other lactic acid separation techniques, such as chemical neutralization, liquid–liquid extraction, membrane separation, and distillation, are also thoroughly reviewed.
Penghasilan asid laktik D semakin mendapat perhatian kerana sifat polimernya, poli asid laktik D, yang termostabil. Kajian ini dijalankan untuk menghasilkan asid laktik D daripada sisa pertanian yang tidak bernilai tinggi seperti sabut kelapa tua (SKT) dan sabut kelapa muda (SKM) melalui teknologi fermentasi. Peringkat pertama kajian, SKTdan SKM dikenakan pra-rawatan beralkali menggunakan 5% larutan natrium hidroksida pada suhu 121 °C selama 15 minit untuk menyingkirkan komponen lignin dan hemiselulosa. Kemudian, dua kaedah hidrolisis dikaji, iaitu hidrolisis berenzim dengan menggunakan enzim Acellerase 1500 (1, 5 dan 10%, i/i) dan hidrolisis berasid dengan menggunakan asid sulfurik (1, 3 dan 5%, i/i). Keputusan menunjukkan hidrolisis berenzim dengan kepekatan 10% enzim Accellerase 1500 (11.09 mg/mL) lebih cekap menukarkan selulosa kepada gula penurun berbanding hidrolisis berasid (0.87 mg/mL) dalam hidrolisat SKT. Manakala, bagi hidrolisat SKM, 5% enzim Accellerase menghasilkan kepekatan gula penu-run yang lebih tinggi berbanding hidrolisis berasid dengan 15.00 dan 1.02 mg/mL. Kadar penukaran gula penurun yang maksimum didapati daripada hidrolisis berenzim SKT dan SKM dengan 55% dan 60%. Pada peringkat kedua, hidrolisat yang mengandungi gula penurun yang tinggi digunakan sebagai sumber karbon untuk penghasilan asid lak-tik D oleh Lactobacillus coryniformis subsp. torquen melalui proses fermentasi (48 jam, 37 ºC, 150 rpm). Pada akhir proses fermentasi, sebanyak 4.93 g/L penghasilan asid laktik D direkodkan dalam kaldu hidrolisat SKT dan 3.98 g/L asid laktik D terhasil dalam kaldu hidrolisat SKM dengan pH kaldu fermentasi tidak dikawal. Kesimpulannya, selulosa dalam kedua-dua sampel SKT dan SKM boleh diuraikan kepada gula penurun melalui hidrolisis berenzim dan seterus-nya berpotensi untuk digunakan sebagai substrat bagi menghasilkan asid laktik D melalui proses fermentasi.
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.
