Maria C. Manca de Nadra, Mario E. Arena and Fabiana M. Saguir
(WFL Publisher Science and Technology, 2003-12)
It is well known that lactic acid bacteria need multiple nutritional requirements for growth. They require numerous amino acids and other growth factors to develop in synthetic media. In this review the amino acid requirements, ...
Divergent synthetic routes to biologically relevant types of compounds: chiral polyfunctional γ-lactams and amino acids
(Elsevier, 2014-09)
Divergent and versatile synthetic routes leading to the title compounds are described. They start from a common chiral precursor derived from (−)-(S)-verbenone and afford polyfunctional γ-lactams and γ- and ε-amino acids. ...
Application of 2,4-D hormetic dose associated with the supply of nitrogen and nickel on cotton plants
(2021-01-01)
Growth traits, yield, N content, photosynthetic pigments, ammonia and amino acids were measured to verify the effect of the interaction between N, Ni, and 2,4-D applied in the cotton crop. The objective was to study the ...
Enhancement of polyunsaturated fatty acid production under low-temperature stress in Cylindrotheca closterium
(Springer, 2020-02-04)
Marine microalgae synthetize great amounts of essential metabolites such as fatty acids and amino acids. In addition, their exposure to stress factors can induce the overproduction of these desirable metabolites. Thus, in ...
Effect of amino acids and peptides on growth of pediococcus pentosaceus from wine
(Plapiqui, 2003-09)
Lactic acid bacteria are characterized by numerous nutritional requirements. The influence of amino acids and peptides on the growth of Pediococcus pentosaceus c1 isolated from argentinean wines was determined. Cells were ...
Amino acid and polyamine membrane transporters in Trypanosoma cruzi: biological function and evaluation as drug targets
(Bentham Science Publishers, 2019-12)
Amino acids and polyamines are involved in relevant processes for the parasite Trypanosoma cruzi, like protein synthesis, stress resistance, life cycle progression, infection establishment and redox balance, among others. ...
Gold-Catalyzed Cycloisomerization of Alkyne-Containing Amino Acids: Controlled Tuning of C–N vs. C–O Reactivity
(Wiley VCH Verlag, 2016-06)
Versatile alkyne-containing amino acids were used as ambident precursors in the divergent synthesis of alkylidenelactones and 1-pyrrolines. Two gold-catalyzed protocols were applied for selective intramolecular O- and ...
An altemative peptide sequencing procedure for low budget laboratories
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
