Empirical economic analysis shows cost-effective continuous manufacturing of cultivated chicken using animal-free medium.

Cellular agriculture aims to meet the growing demand for animal products. However, current production technologies result in low yields, leading to economic projections that prohibit cultivated meat scalability. Here we use tangential flow filtration for continuous manufacturing of cultivated meat to produce biomass of up to 130 × 10 cells per ml, corresponding to yields of 43% w/v and multiple harvests for over 20 days.

Spontaneous immortalization of chicken fibroblasts generates stable, high-yield cell lines for serum-free production of cultured meat.

Cellular agriculture could meet growing demand for animal products, but yields are typically low and regulatory bodies restrict genetic modification for cultured meat production. Here we demonstrate the spontaneous immortalization and genetic stability of fibroblasts derived from several chicken breeds. Cell lines were adapted to grow as single-cell suspensions using serum-free culture medium, reaching densities of 108 × 10 cells per ml in continuous culture, corresponding to yields of 36% w/v.

Differential metabolism of L-phenylalanine in the formation of aromatic volatiles in melon (Cucumis melo L.) fruit.

Studies on the active pathways and the genes involved in the biosynthesis of L-phenylalanine-derived volatiles in fleshy fruits are sparse. Melon fruit rinds converted stable-isotope labeled L-phe into more than 20 volatiles. Phenylpropanes, phenylpropenes and benzenoids are apparently produced via the well-known phenylpropanoid pathway involving phenylalanine ammonia lyase (PAL) and being (E)-cinnamic acid a key intermediate.

Systems approach for exploring the intricate associations between sweetness, color and aroma in melon fruits.

Background: Melon (Cucumis melo) fruits exhibit phenotypic diversity in several key quality determinants such as taste, color and aroma. Sucrose, carotenoids and volatiles are recognized as the key compounds shaping the above corresponding traits yet the full network of biochemical events underlying their synthesis have not been comprehensively described. To delineate the cellular processes shaping fruit quality phenotypes, a population of recombinant inbred lines (RIL) was used as a source of phenotypic and genotypic variations.
