Ever increasing antibiotic resistance due to biofilms has sparked a search for plant-based replacements. This study examines anti-biofilm potential of essential oils from lemon (Citrus limon), lemongrass (Cymbopogon citratus), and lavender (Lavandula officinalis) against 26 clinical isolates of E. coli. Essential oils (EOs) were extracted by using hydro-distillation and characterized by GC-MS and FT-IR. Biofilms were quantitatively and qualitatively evaluated. The extracted essential oils had yields ranging from 1.37 to 1.45 (w/v). The main constituents were limonene (94%) in lemon, citral (42%) and ketones (9%) in lemongrass, and linalool (35%) and linalyl anthranilate (20%) in lavender EO. MICs and MBCs of EOs were in the range of 3.13-50 µg/ml. The oils under investigation exhibited notable biofilm inhibition and eradication properties. The percent inhibition and eradication varied between 6-89% and 3-82.25% (p < 0.0001), respectively. These findings suggest that essential oils from lemon, lemongrass, and lavender may offer a promising natural approach to combat E. coli biofilms and associated infections. Further research is warranted to elucidate the underlying mechanisms of action and to explore their clinical applications.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143969653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on the isolation, screening, and comparison of Bacillus cereus strains to produce extracellular lipases utilizing agro-industrial waste through solid-state fermentation. The results indicate that B. cereus exhibited optimal lipase production with soybean extract, yielding 41.2 ± 1.08 µ/ml (p < 0.05), followed by bagasse with 40.5 ± 0.97 µ/ml (p < 0.05). Other substrates, including rice bran (9.9 µ/ml), wheat bran (25.8 µ/ml), sunflower seed (24.0 µ/ml), and oat bran (10.2 µ/ml), demonstrated significantly lower enzyme activity. Additionally, lipase production from fruit peels was assessed, with banana yielding 21.1 µ/ml, orange 20.3 µ/ml, melon 16.3 µ/ml, and watermelon 16.43 µ/ml. Various oil wastes were also evaluated, showing lipase activities of 14.6 µ/ml (Sitara oil), 13.3 µ/ml (Shan oil), 11.0 µ/ml (automobile oil), and 10.2 µ/ml (cooking oil). The bacterial lipases produced from B. cereus demonstrated maximum hydrolysis of tributyrin agar medium at 40°C (p < 0.05).

In this study, 42 adolescent male Sprague-Dawley rats were divided into six groups: control (C), socially isolated (SI), voluntary exercise (VE), regular exercise (RE), socially isolated + voluntary exercise (SI-VE), and socially isolated + regular exercise (SI-RE). Socially isolated groups were kept in separate cages for 4 weeks. Treadmill and wheel running were used in the exercise groups. The following behavioral tests-elevated plus maze (EPM), open field, ultrasonic vocalization (USV), and Morris water maze (MWM)-rats were euthanized, and brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and vascular endothelial growth factor (VEGF) levels were measured in the prefrontal cortex (PFC) and hippocampus. Statistically, the differences between the groups were evaluated by one-way ANOVA and post hoc LSD tests using IBM SPSS software. In the EPM, locomotor activity was higher in the voluntary exercise groups. In the MWM, both regular exercise groups found the platform faster. In the USV, the SI-RE group produced more 50-kHz sounds. BDNF and NGF levels in the hippocampus were higher in the SI-RE and SI-VE groups; VEGF levels were higher in the SI-RE group. Neuron density in the PFC increased in the SI-RE and VE groups, while neuron density in the hippocampus increased in the SI-RE, SI-VE, and VE groups. According to the findings, we showed that voluntary exercise reduces social isolation-induced anxiety, and involuntary/regular exercise both reduces anxiety and has potential benefits on cognitive functions.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"71-85"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143448005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of 2D video stimuli may enable researchers to systematically manipulate the perspective from which demonstrations are observed, thereby widening the range of methods available to study cognitive skills related to imitation. In this study, we explore the possibility of using 2D stimuli to test action matching in dogs, including when demonstrations are seen from different perspectives. We examined two dogs' imitative performance using videos projected on a screen; while, the owner interacted with the dog remotely through an online meeting software. The dogs were first trained to match human actions seen on a screen frontally, and then were tested when the projected demonstrations were seen frontally, from the side, and from above. Results revealed that both dogs matched the demonstrated actions from frontal and, notably, also from side perspectives, at least to some extent, consistent with familiarity of their daily interactions with humans. However, action matching from an above perspective presented challenges, indicating the potential influence of observational experience and highlighting the importance of perspective manipulation when investigating imitation abilities. These findings show that it is possible to use 2D videos to test imitation in dogs, thereby expanding the potential methodologies to study imitation and other related cognitive skills.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"33-40"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140875736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the potential of halotolerant bacteria, isolated from the rhizosphere of wild halotolerant plants in Turkey's Salt Lake basin, to enhance salt stress tolerance in maize (Zea mays L.). The rhizospheres of 17 different wild halotolerant plants were selected for bacterial isolation, resulting in the identification of 22 halotolerant bacteria using 16S rRNA sequence analysis. Among these, 19 isolates were found to possess positive activity for 1-aminocyclopropane-1-carboxylate (ACC) deaminase and nitrogen fixation. When the maize seeds inoculated with these 19 isolates were grown under normal conditions, four isolates‒TG-4 (Halomonas arcis), TG-8 (Marinococcus tarigensis), TG-12 (Halobacillus dabanensis), and TG-20 (Halomonas eurihalina)-significantly stimulated seedling growth and development. To evaluate the effect of these four isolates on salt tolerance, inoculated seeds were grown under various salt conditions (0.0, 75, 150, and 250 mM NaCl). The responses of plants to salt stress were analyzed by evaluating growth parameters, membrane damage, photosynthetic pigment and proline content, reactive oxygen species and lipid peroxidation levels, and antioxidant enzyme activities. According to the parameters, the results indicated that TG-4, TG-8, and TG-12, in particular, have the potential to function as plant growth-promoting rhizobacteria and effectively enhance salt stress tolerance in the maize seedlings. Overall, this research highlights the potential of halotolerant bacteria to improve salt stress tolerance in maize plants through multifaceted mechanisms, offering valuable insights for sustainable agriculture in saline environments.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"101-116"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143673231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant astrobiology delves into the adaptations and mechanisms that might allow Earth's flora to flourish in the harsh conditions of outer space and other celestial bodies. This review aims to shed light on the captivating field of plant astrobiology, its implications, and the challenges and opportunities it presents. Plant astrobiology marries the disciplines of botany and astrobiology, challenging us to envision the growth of plants beyond Earth's atmosphere. Researchers in this field are not only exploring the potential for plant life on other planets and moons but also investigating how plants could be harnessed to sustain life during extended space missions. The review discusses how plants could adapt to environments characterized by low gravity, high radiation, extreme temperature fluctuations, and different atmospheric compositions. It highlights the physiological changes necessary for plants to survive and reproduce in these conditions. A pivotal concept is the integration of plants into closed-loop life support systems, where plants would play a crucial role in recycling waste products, generating oxygen, and producing food. The review delves into ongoing research involving genetic modifications and synthetic biology techniques to enhance plants' resilience in space environments. It addresses ethical considerations associated with altering organisms for off-planet habitation. Additionally, the review contemplates the psychological and emotional benefits of having greenery in enclosed, isolated space habitats. The review concludes that by employing advanced research methodologies, the field of plant astrobiology can greatly enhance the viability and sustainability of future space missions, highlighting the essential role of plants in sustaining long-term human presence beyond Earth.","PeriodicalId":8853,"journal":{"name":"Biologia futura","volume":" ","pages":"1-18"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142280024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
