Tryptone in Growth Media Enhances Pseudomonas putida Biofilm

Microorganisms 2022 Mar 14;10(3):618.35336191 PMC8954664

Extracellular factors and growth conditions can affect the formation and development of bacterial biofilms. The biofilm of Pseudomonas putida has been studied for decades, but so far, little attention has been paid to the components of the medium that may affect the biofilm development in a closed system. It is known that Fis strongly enhances biofilm in complete LB medium. However, this is not the case in the defined M9 medium, which led us to question why the bacterium behaves differently in these two media. Detailed analysis of the individual medium components revealed that Tryptone as the LB proteinaceous component maintains biofilm in its older stages. Although the growth parameters of planktonic cells were similar in the media containing Tryptone or an equivalent concentration of amino acids, only the Tryptone had a positive effect on the mature biofilm of the wild type strain of P. putida. Thus, the peptides in the environment may influence mature biofilm as a structural factor and not only as an energy source. Testing the effect of other biopolymers on biofilm formation showed variable results even for polymers with a similar charge, indicating that biopolymers can affect P. putida biofilm through a number of bacterial factors.

Tryptone-stabilized gold nanoparticles induce unipolar clustering of supernumerary centrosomes and G1 arrest in triple-negative breast cancer cells

Sci Rep 2019 Dec 13;9(1):19126.31836782 PMC6911093

Gold nanoparticles of different sizes, shapes, and decorations exert a variety of effects on biological systems. We report a novel mechanism of action of chemically modified, tryptone-stabilized gold nanoparticles (T-GNPs) in the triple-negative breast cancer (TNBC) cell line, MDA-MB-231. The T-GNPs, synthesized using HAuCl4.3H2O and Tryptone and characterized by an assortment of spectroscopy techniques combined with high-resolution electron microscopy, demonstrated strong antiproliferative and anti-clonogenic potential against MDA-MB-231 cells, arresting them at the G1 phase of the cell cycle and promoting apoptosis. The molecular mechanism of action of these particles involved induction of unipolar clustering and hyper amplification of the supernumerary centrosomes (a distinctive feature of many tumour cells, including TNBC cells). The clustering was facilitated by microtubules with suppressed dynamicity. Mass spectrometry-assisted proteomic analysis revealed that the T-GNP-induced G1 arrest was facilitated, at least in part, by downregulation of ribosome biogenesis pathways. Due to the presence of supernumerary centrosomes in many types of tumour cells, we propose chemical induction of their unipolar clustering as a potential therapeutic strategy.

Employing Tryptone as a General Phase Transfer Agent to Produce Renal Clearable Nanodots for Bioimaging

Small 2015 Aug 12;11(30):3676-85.25914195 10.1002/smll.201500287

Hydrophobic ultrasmall nanoparticles synthesized in nonpolar solvents exhibit great potential in biomedical applications. However, a major challenge when applying these nanomaterials in biomedical research is the lack of a versatile strategy to render them water dispersible while preserving the hydrodynamic diameter (HD) to be less than 8 nm for efficient renal clearance. To address this problem, Tryptone is employed as the novel ligand to fabricate a simple, versatile, and inexpensive strategy for transferring hydrophobic NaGdF(4) nanodots (3 nm in diameter) from organic phase into aqueous phase without any complicated organic synthesis. The paramagnetic properties of NaGdF(4) nanodots are well retained after the phase transfer process. In particular, the tryptone-NaGdF(4) nanodots have ultrasmall HD (ca., 7.5 nm), which greatly improves their tumor accumulation and facilitates renal clearance within 24 h postinjection. The as-prepared tryptone-NaGdF(4) nanodots can also be further functionalized with other molecules for extensively biomedical and bioanalytical applications. Furthermore, the proposed strategy can easily be extended to transfer other types of inorganic nanoparticles from hydrophobic to hydrophilic for facilitating biomedical applications.

Tryptone-stabilized gold nanoparticles target tubulin and inhibit cell viability by inducing an unusual form of cell cycle arrest

Exp Cell Res 2017 Nov 15;360(2):163-170.28887025 10.1016/j.yexcr.2017.09.002

Gold nanoparticles have been investigated extensively for their molecular mechanisms of action and anticancer potential. We report a novel, tubulin-targeted antiproliferative mechanism of action of tryptone-stabilized gold nanoparticles (TsAuNPs). TsAuNPs, synthesized using HAuCl4路3H2O and Tryptone and characterized by a variety of spectroscopic methods and transmission electron microscopy, were found to be inhibitory to viability of human pancreatic (PANC-1), cervical (HeLa), and breast (MDA-MB-231) cancer cell lines in a concentration-dependent manner, with highest efficacy against PANC-1 cells. The particles strongly inhibited the clonogenic propagation of PANC-1 cells. TsAuNPs-mediated inhibition of cell viability involved an unusual mode of cell cycle arrest (arrest at both G0/G1 phase and S-phase) followed by apoptosis. In vitro, TsAuNPs bound purified tubulin, competitively inhibited anilinonaphthalene sulfonate binding to tubulin, and suppressed tubulin assembly. In cells, tubulin-TsAuNPs interactions were manifested as a disrupted microtubule network, defective reassembly of cold-disassembled microtubules, and induction of tubulin acetylation. Our data indicate that TsAuNPs inhibit cell viability by inducing differential cell cycle arrest possibly through disrupted dynamicity of cellular microtubules.

Tryptone-yeast extract broth as a culture medium for Haemophilus pleuropneumoniae and Haemophilus parasuis to be used as challenge inocula

Can J Vet Res 1986 Jul;50(3):441-3.3755642 PMC1255242

Haemophilus pleuropneumoniae and Haemophilus parasuis were grown in a liquid medium containing Tryptone and yeast extract. Whereas culture turbidity during exponential growth of either organism was proportional to the number of viable cells, continued incubation of stationary phase cultures was accompanied by a dramatic decrease in viability with no corresponding decrease in culture turbidity. It is concluded that the medium described should prove useful for the growth of porcine haemophili for use in experimental infections provided the stage of growth is given due consideration.
