Characterization of collagen and its hydrolysate from yellowfin tuna Thunnus albacares skin and their potencies as antioxidant and antiglycation agents

Fisheries Science - Collagen is one of the biopolymer proteins that may be useful for food and non-food purposes. Recently, even for collagen, it is becoming necessary to meet the requirements of...     

Monitoring of the Roundup Ready soybean in the Vojvodina province in Serbia

The Vojvodina province is the most important agricultural area of the Republic of Serbia and is its largest soybean producer. Serbian low forbids the introduction of genetically modified organisms (GMO) into the environment and demands labeling of food containing more than 0.9% GMO. This aim of this study is to monitor the Roundup Ready (RR) soybean in fields and in food products using PCR and immunoassays. A duplex PCR reaction was performed to analyze the lectin gene and 35S promoter using DNA isolated from soybean leaf and seed sample. Specific detection of RR markers was performed using nested PCR and verified by immunoassay. RR soybeans were found in 68 fields in samples from 2003 and 28 fields in 2004. The presence of the RR soybean was confirmed in 44 seed samples out of 7142 samples examined in 2006 and in 108 out of 7171 samples examined in 2007. The data presented here are the first to demonstrate the presence of RR soybean in the Serbia fields.     

Marine Microbial-Derived Resource Exploration: Uncovering the Hidden Potential of Marine Carotenoids

Microbes in marine ecosystems are known to produce secondary metabolites. One of which are carotenoids, which have numerous industrial applications, hence their demand will continue to grow. This review highlights the recent research on natural carotenoids produced by marine microorganisms. We discuss the most recent screening approaches for discovering carotenoids, using in vitro methods such as culture-dependent and culture-independent screening, as well as in silico methods, using secondary metabolite Biosynthetic Gene Clusters (smBGCs), which involves the use of various rule-based and machine-learning-based bioinformatics tools. Following that, various carotenoids are addressed, along with their biological activities and metabolic processes involved in carotenoids biosynthesis. Finally, we cover the application of carotenoids in health and pharmaceutical industries, current carotenoids production system, and potential use of synthetic biology in carotenoids production.     

Artoindonesianin L, a new prenylated flavone with cytotoxic activity from Artocarpus rotunda.

A new prenylated flavone, named artoindonesianin L (1), was isolated from Artocarpus rotunda (Hout) Panzer (Moraceae). Its structure was elucidated as on the basis of spectroscopic evidence. Along with this new compound, four known phenolic compounds were also isolated from this plant and identified as artonins M (2) and E (3), cycloartobiloxanthone (4) and artonin O (5). All these compounds showed significant cytotoxicity against murine P388 leukemia cells.
