Combinatorial effects of bovicin HC5 and epsilon-polylysine against Alicyclobacillus acidoterrestris in orange juice
… against vegetative cells and germinated endospores of A. acidoterrestris DSMZ 2498 grown in AAM broth and orange juice. A significant decrease (P < 0.05) in the microbial growth and specific growth rate, and an increase in lag phase (P < 0.05) of vegetative cells and germinated endospores …

Development and evaluation of novel antimicrobial solutions against biofilms and planktonic microbial growth
… (MRSA), Candida albicans, and Bacillus cereus endospores. The Planktonic assay demonstrated the effectiveness of these solutions as high-level disinfectant solutions per FDA standards, which includes use as a sporacidial agent. The solutions were capable of causing a 10⁸ reduction in endospores …

Antimicrobial Materials for Water Disinfection Based on Visible-Light Photocatalysts
… coli, P. aeruginosa, S. aureus and B. subtilis endospores. The results of mechanistic study provided evidence of oxidative damages, and indicated that hydroxyl radicals are one of the key killing species. Atomic force microscopy and electron microscopy showed that the cell walls were attacked by …

Relative Expression of Germination Genes SleB, GerAC, and Gpr in Heat Treated Bacillus licheniformis and Bacillus subtilis
… the ability to form metabolically dormant endospores characterized by resistance to heat, UV, and chemical treatment. Spores have undetectable metabolic activity and remain impervious to the harsh conditions of their environment, but they can detect environmental cues signaling favorable …

Molecular Engineering Approaches against Germs, Spores and Biofilm Formation
… combat the extreme survivability of bacterial endospores; and lastly to explore the possible new routes and targets for future anti-virulence small molecules against biofilm formation. This dissertation is thus divided into these three sections accordingly: Traditional zwitterionic polymers …

Isolasi dan identifikasi bakteri rhizobium dari akar tanaman alfafa (Medicago sativa L.)
… positive results. Then continued with staining endospores with negative results. According to the test results of gram stain, catalase test, and staining endospores obtained five samples have similar characteristics and can be sure that these are the five isolates of bacteria Rhizobium. Taken as …

Characterization of endoglucanase cela from the rumen bacterium Clostridium longisporum
… from Varel (1989) because oxygen-resistant endospores might be suitable "vectors" for the introduction of genetically modified enzyme systems into the rumen via animal feeds. It is a sporadically occurring rumen bacterium and its role in ruminal cellulolysis is unclear. The aim of this …

Preserving spore dormancy
… harsh conditions by forming dormant, resistant endospores that later resume growth through germination. Because germination abolishes spore resistance, developing spores must avoid responding to germinants too early. This thesis examines how sporulating bacteria prevent premature germination …

Functionalization of phage endolysins to treat infections of spore-forming Clostridia bacteria in the era of antibiotic resistance
… not only because they form highly resistant endospores but because they produce toxins and exhibit antibiotic resistance. *Clostridioides difficile* is a nosocomial pathogen responsible for thousands of deaths every year, whereas *Clostridium perfringens* is a common cause of food poisoning …

Towards engineering the gut microbiota
… considerations. In the first study, I examined endospores and other resistant cell types in the gastrointestinal communities of unrelated humans to identify the ecological role of these states in the distribution of bacterial populations in healthy people. I used this information to infer shared …
