“…The absence of difference between the two process scales also indicates that the cultivar had no effect on the physical characteristics of the products obtained. During the following fermentation and pressing operations, neither mechanical forces nor bacterial activity did cause further changes in damaged cell ratio, contrary to other observations (Williams et al, 2019, Ha et al, 2020; Table 1). This may indicate that the maximum extent of cell damage was reached after rasping.…”

“…Other microorganisms such as microalgae also accumulate lipids in the presence of salts stress which has potential use in the production of biofuels. In the case of the microalgae, Chlamydomonas reinhardtii, this increase of neutral lipids was reported to depend on MAPK activation [50,51].…”

As opportunistic pathogen, Candida albicans adapts to different environmental conditions and its corresponding stress. The Hog1 MAPK (Mitogen Activated Protein Kinase) was identified as the main MAPK involved in the response to osmotic stress. It was later shown that this MAPK is also involved in the response to a variety of stresses and therefore, its role in virulence, survival to phagocytes and establishment as commensal in the mouse gastrointestinal tract was reported. In this work, the role of Hog1 in osmotic stress is further analyzed, showing that this MAPK is involved in lipid homeostasis. The hog1 mutant accumulates lipid droplets when exposed to osmotic stress, leading to an increase in cell permeability and delaying the endocytic trafficking routes. Cek1, a MAPK also implicated in the response to osmotic challenge, did not play a role in lipid homeostasis indicating that Hog1 is the main MAP kinase in this response. The alteration on lipid metabolism observed in hog1 mutants is proposed to contribute to the sensitivity to osmotic stress.

“…Due to the challenges resulting from global warming and the depletion of fuel sources along with the energy price fluctuations, developing a renewable energy source has become one of the world's highest priorities [6,7]. In this endeavor, biofuel has received ever-growing attention as an appropriate alternative for overcoming the problems associated with petroleum fuels [8,9]. Biofuels include gaseous and liquid fuels that are usually produced from renewable resources [10][11][12][13].…”

In this study, ZSM-22 was synthesized using N,N-diethylaniline as a template through a hydrothermal method. The proton and various metals such as zirconium, strontium, and iron were immobilized on the surface of obtained zeolites through the ion exchange method. The catalysts were studied by Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Brunauer–Emmett–Teller (BET) adsorption isotherms, Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM), Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) elemental analysis, and Temperature-Programmed Desorption of ammonia (TPD-NH3) technique for determining the number of acid sites. In the esterification reaction of oleic acid, the operating conditions such as catalyst dosage, temperature, molar ratio of methanol to oil, and reaction time were optimized and adjusted at 11 wt%, 70°C, 10 : 1, and 48 h subsequently. The maximum yield% of 48.07% was achieved in the presence of Zr-H-ZSM-22 at optimum conditions. In order to improve the efficiency of three zeolites Zr-H-ZSM-22, Fe-H-ZSM-22, and Sr-H-ZSM-22, the core-shell structures with SiO2 coating were prepared. Zr-H-ZSM-22@SiO2 was less active than Zr-H-ZSM-22 due to the SiO2 coverage of Lewis active sites.
