Background: Soybean residue (okara) is an agricultural by-product, which is rich in protein and fiber. This study evaluated a novel sequential process which combined fungal pretreatment (F) and twin screw extruder (E), to hydrolyze okara. The sequence of the pretreatment steps, and extruder at screw speeds 200 rpm (200) or 600 rpm (600), were tested. Next, soluble nutrients were extracted to create Fokara, EFokara200, EFokara600, FEokara200 and FEokara600 okara media.
Results: All the prepared okara media could support the growth and carotenoid production by the yeast Rhodosporidium toruloides. This suggested that okara proteins and polysaccharides were successfully hydrolyzed by extrusion and fungal pretreatment, into soluble nutrients. Rhodosporidium toruloides accumulated the highest biomass of 23.7 mg mL dry cell weight (DCW), when grown on FEokara600 media. This was higher as compared to commercial YPG (yeast extract-peptone-glycerol) media (18.7 mg mL DCW). However, R. toruloides accumulated the highest carotenoid production of 13.2 µg mL when grown on EFokara200 media as the nutrient source. This was comparable to carotenoid production of 13.1 µg mL when R. toruloides was grown on YPG media.
Conclusion: Extrusion in combination with fungal pretreatment, is a low cost process, to hydrolyze and re-use okara, for carotenoid production. © 2018 Society of Chemical Industry.

The dairy industry is a significant sector within the food industries, known for its high-water consumption and consequent generation of dairy wastewater (DWW), which is rich in pollutants like Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). Improper disposal of DWW poses serious environmental challenges, including eutrophication and highlighting the need for sustainable biological treatment methods. This study investigates the potential of indigenous cyanobacterial strains , , , and for the bioremediation of DWW.

Astaxanthin (ASX), "king of carotenoids", is a xanthophyll carotenoid that is characterized by a distinct reddish-orange hue, procured from diverse sources including plants, microalgae, fungi, yeast, and lichens. It exhibits potent antioxidant and anti-ageing properties and has been demonstrated to mitigate ultraviolet-induced cellular and DNA damage, enhance immune system function, and improve cardiovascular diseases. Despite its broad utilization across nutraceutical, cosmetic, aquaculture, and pharmaceutical sectors, the large-scale production and application of ASX are constrained by the limited availability of natural sources, low production yields and stringent production requirements.

The evolutionary success of angiosperms, which make up more than 95 percent of the world's terrestrial flora, is largely based on their interactions with animal pollinators. Indeed, it is estimated that, on average, 87.5 percent of flowering plants are pollinated by animals.

Lycopene is a tetraterpene compound belonging to carotenoids that are widely present in tomatoes and similar products. It is known as a powerful anti-oxidant and a non-provitamin A carotenoid. Lycopene has been found to effectively improve diabetes mellitus and its complications, such as cardiac complications, disorders caused by oxidative stress, and liver and neurological disorders.

brown seaweed () is reported to exhibit several biological activities that promote human health, but it does not have the ability to withstand harsh environmental conditions, such as high temperatures and oxygen exposure. Encapsulation of extraction through different techniques is known to, optimize physicochemical properties, biological activities, maintain stability, and is an effective way to improve the shelf life of different foods. In the present study, the encapsulation of SIE was carried out by the freeze-drying method using maltodextrin, whey protein isolate (WPI), and chitosan.
