The current study describes the extracellular hydrolytic activities of halophilic bacteria isolated from subterranean rock salt. The estimated number of grown colonies was approximately 3000 per gram of a rock salt on the surface of the medium MH containing 10% NaCl. The investigated strains, randomly selected from the colonies observed on the plate, showed at least one of the tested extracellu...
BACKGROUND Skeletons are formed in a wide variety of shapes, sizes, and compositions of organic and mineral components. Many invertebrate skeletons are constructed from carbonate or silicate minerals, whereas vertebrate skeletons are instead composed of a calcium phosphate mineral known as apatite. No one yet knows why the dynamic vertebrate skeleton, which is continually rebuilt, repaired, and...
Pathophysiological changes in the mouth of patients with diabetes mellitus (DM) predispose to overgrowth of Candida albicans. Various virulence factors such as proteinase and phospholipase production are involved in the process of degradation of the host cell membrane. These enzymes are involved in binding Candida species, especially in the hyphae stage, to the target tissue. In this study, the...
Elwyn et al. (1, 2) have demonstrated that the C1 unit formed from serine is of the oxidation level of formaldehyde rather than formate. They compared the dilution of the Cl4 and deuterium of 2 ,3-deuterio-3-C14,N15L-serine that occurred during the conversion of the serine B-carbon to methyl groups in rats. The results indicated that this carbon did not pass through an intermediate, such as for...
The hydrolytic degradation of oriented poly(L-lactide-co-glycolide) 85 L/15 G (PLGA 85/15) sample materials with various amounts of lactide monomer was monitored in vitro at 37 °C. The materials were manufactured from medical grade PLGA 85/15 by a two-step melt extrusion-die drawing process. Results showed that the hydrolytic degradation rate depended highly on the lactide monomer content, whic...
Thermochemical modification of lysozyme enables it to retain its oligomers, showing a wide spectrum of increased antibacterial activities. It also results in significant loss of hydrolytic activity of the enzyme. The objective of this study is to analyse the protective effect of resorcinol on the hydrolytic activity of modified lysozyme using a high temperature method and the oligomerization de...
