Abstract
In this study, the model of heat stress was constructed in primary chick embryonic myocardial cells at 42 °C for 4 h. Proteome analysis using DIA identified 245 differentially expressed proteins (DEPs) (Q-value <0.05, fold change >1.5), of which 63 proteins were up-regulated and 182 proteins were down-regulated. Many were related to metabolism, oxidative stress, oxidative phosphorylation and apoptosis. Gene Ontology (GO) analysis showed that many DEPs under heat stress were involved in regulating metabolites and energy, cellular respiration, catalytic activity and stimulation. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that DEPs were enriched in metabolic pathways, oxidative phosphorylation, citrate cycle (TCA cycle), cardiac muscle contraction, and carbon metabolism. The results could help understanding of the effect of heat stress on myocardial cells and even the heart and possible action mechanism at the protein level.

Galactomyces geotrichum mold isolated from a traditional fried cottage cheese produced omega-3 fatty acids. Int J Food Microbiol 2020; 319:108503. [PMID: 31923767 DOI: 10.1016/j.ijfoodmicro.2019.108503] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 12/20/2019] [Accepted: 12/27/2019] [Indexed: 11/21/2022]
Abstract
Thirty nine strains of Galactomyces geotrichum molds were isolated from a traditional fried cottage cheese and production of polyunsaturated fatty acids (PUFA) was assessed. Among them eleven strains produced an extracellular lipids enriched in n-6 and n-3 PUFA. The extracellular lipids produced by G. geotrichum strain 38 contained the highest amounts of total PUFA (24.3%), with the highest contribution of n-3 fatty acids (17.9%), where α-linolenic, eicosapentaenoic, docosapentaenoic and docosahexaenoic acids were the main contributors. To obtain maximal production of PUFA, composition of the medium consisted of 10 g/L rapeseed oil, 5 g/L yeast extract, 0.05 g/L K2HPO4, 0.17 g/L MgSO4, 0.015 g/L MnSO4, 0.015 g/L ZnSO4, 0.05 g/L FeSO4, and 10 mg/L vitamin B12. The optimal growth conditions at 30 °C involve: aeration at 1.5 vvm (volume of air per volume of broth per minute) at pH 6.5. The cheese produced under described conditions contained higher amount of n-3 PUFA (0.25 mg/g cheese) in comparison to control (0.01 mg/g). α-Linolenic acid predominated among n-3 fatty acids. Galactomyces geotrichum is a natural microflora of dairy products, and could be used to enrich food/cheese in deficient omega-3 lipids.

Abstract
In this study, productions of microalgal proteins were explored via a circular economy concept. First, production of proteins from Chlorella vulgaris FSP-E (CV) and Chlorella sorokiniana (CS) was optimized by using favorable cultivation conditions and strategies. The optimal CO2 concentration for the growth of both microalgae was 5% (v/v), while the optimal nitrogen source for CV and CS were 12 mM of NaNO3 and NH4Cl, respectively. Addition of 12 mg/L ammonium iron (III) citrate enhanced protein production. Next, semi-batch cultivation strategy was employed to achieve a protein production of 793.3 and 812.8 mg/L for CV and C S, representing a 4.86 and 2.77 fold increase, respectively, in protein productivity. The obtained microalgal proteins consist of 40% essential amino acids. The CV and CS proteins possess prebiotic activities as they enhanced the growth of Lactobacillus rhamnosus ZY by 48 and 74%, respectively, with a good antibacterial activity against predominant pathogens.

Abstract
The ω-3/long-chain polyunsaturated fatty acids (LC-PUFAs) play an important role in human health, but they cannot be synthesized in sufficient amounts by the human body. In a previous study, we obtained an engineered Schizochytrium sp. strain (HX-RS) by exchanging the acyltransferase (AT) gene, and it was able to co-produce docosahexaenoic acid and eicosapentaenoic acid. To investigate the mechanism underlying the increase of PUFA content in HX-RS, the discrepancies of fermentation performance, key enzyme activities and intracellular metabolites between HX-RS and its wild-type parent strain (WTS) were analyzed via fed-batch fermentation in 5-L bioreactors. The results showed that the cell dry weight (CDW) of HX-RS was higher than that of the WTS. Metabolomics combined with multivariate analysis showed that 4-aminobutyric acid, proline and glutamine are potential biomarkers associated with cell growth and lipid accumulation of HX-RS. Additionally, the shift of metabolic flux including a decrease of glyceraldehyde-3-phosphate content, high flux from pyruvate to acetyl-CoA, and a highly active glycolysis pathway were also found to be closely related to the high PUFA yield of the engineered strain. These findings provide new insights into the effects of exogenous AT gene expression on cell proliferation and fatty acid metabolism.

Abstract
The proteomics strategy was utilized to analyze and identify the gold adsorption proteins from Tepidimonas fonticaldi AT-A2, due to its outstanding performance in gold-binding and recovery. The results showed that three small proteins, including histidine biosynthesis protein (HisIE), iron donor protein (CyaY) and hypothetical protein_65aa, have a higher ability to adsorb gold ions because of the negatively charged domains or metal binding sites. On the other hand, the Salmonella PmrA/PmrB two-component system first replaces the iron (III)-binding motif using the peptide sequence from hypothetical protein_65aa, and this is then used to reveal the sensing and responsiveness to gold metal ions, which is totally different from the performance of traditional gold binding peptide (GBP) on the crystals on the surface of gold (111). We have successfully demonstrated an integrative proteomics and bacterial two-component system to explore the novel GBP. Finally, the heterologous over-expression of GBP by E. coli and the equilibrium of binding capacity for Au(III) have been conducted.
