Review
Natural environments possess a reservoir of compounds exerting antimicrobial activity that are forms of defence for some organisms against others. Recently, they have become more and more attractive in the food sector due to the increasing demand for natural compounds that have the capacity to protect food from pathogenic microorganisms. Among foodborne pathogens, can contaminate food during production, distribution, or storage, and its presence is especially detected in fresh, raw food and ready-to-eat products. The interest in this microorganism is related to listeriosis, a severe disease with a high mortality rate that can occur after its ingestion. Starting from this premise, the present review aims to investigate plant extract and fermented plant matrices, as well as the compounds or mixtures of compounds produced during microbial fermentation processes that have anti-listeria activity.

Review
The photocatalytic material-microorganism hybrid system is an interdisciplinary research field. It has the potential to synthesize various biocompounds by using solar energy, which brings new hope for sustainable green energy development. Many valuable reviews have been published in this field. However, few reviews have comprehensively summarized the combination methods of various photocatalytic materials and microorganisms. In this critical review, we classified the biohybrid designs of photocatalytic materials and microorganisms, and we summarized the advantages and disadvantages of various photocatalytic material/microorganism combination systems. Moreover, we introduced their possible applications, future challenges, and an outlook for future developments.

Review
Differential shotgun proteomics identifies proteins that discriminate between sets of samples based on differences in abundance. This methodology can be easily applied to study (i) specific microorganisms subjected to a variety of growth or stress conditions or (ii) different microorganisms sampled in the same condition. In microbiology, this comparison is particularly successful because differing microorganism phenotypes are explained by clearly altered abundances of key protein players. The extensive description and quantification of proteins from any given microorganism can be routinely obtained for several conditions within a few days by tandem mass spectrometry. Such protein-centred microbial molecular phenotyping is rich in information. However, well-designed experimental strategies, carefully parameterized analytical pipelines, and sound statistical approaches must be applied if the shotgun proteomic data are to be correctly interpreted. This minireview describes these key items for a quick molecular phenotyping based on label-free quantification shotgun proteomics.

is an intestinal protist that presents worldwide distribution, colonizes animal and human hosts, and is classified into at least 34 ribosomal subtypes (STs). Herein, we conducted an update based on studies reporting -positive samples obtained from diverse hosts in the Americas. We described the distribution throughout the continent by assembling maps representing the distribution of STs and the most important 18S-rRNA alleles. Thirty-nine articles from the previous study, "A summary of subtypes in North and South America," and forty-one additional articles from March 2019 to March 2022 were considered. The most common subtype described was ST3, representing the highest percentage of positive samples. Other recently identified STs include ST12, ST13, and ST16 in humans, and ST10, ST14, and ST17 in animals. Novel subtypes have also been described in this continent. We assembled and updated the distribution of in the Americas. We hope this delivers new understandings and knowledge of this microorganism's prevalence and genetic diversity.

Review
Oil tea Camellia is a major woody oil plant, which has a positive influence on alleviating the contradiction between supply and demand of edible oil in China. Microbial fertilizer for Oil tea Camellia is urgently needed in current production, and it is of great significance to improve the yield and quality. Culturable functional microorganisms are the basis of research and development for microbial fertilizer. In this study, culturable microorganisms which had abilities of antagonism, growth promotion, phosphorus solubility, nitrogen fixation and drought resistance, were integrated from oil tea literature. And the strains potential application ability were evaluated in terms of functionality, safety and adaptability, culture characteristics, suitable conditions and colonization or infection ability of strains. The results showed that the strains with strongest antagonistic ability were s D2WM and Y13. BbTK-01 and FJMa201101 had the strongest insect resistant ability. and can promote oil tea fastest growth. Phosphorus dissolving ability of NC285 and 6-Y-09 were strongest. The strains with strongest Nitrogen fixing ability were N7-3 and B7-7, and the strains with strongest improving drought resistance ability were and Comprehensive evaluation of strains showed that Y13 and N7-3 had a good applied potential ability. This study would save time-consuming of isolate, purify and identify repetitively for the researchers of functional bacteria of oil tea Camellia. Meanwhile it provides a research basis for selecting targeted strains and constructing the combination of functional strains, therefore provides data support for fertilizer efficiency.

Review
Marine microorganisms produce a series of promising enzymes that have been widely used or are potentially valuable for our daily life. Both classic and newly developed biochemistry technologies have been broadly used to study marine and terrestrial microbiological enzymes. In this brief review, we provide a research update and prospects regarding regulatory mechanisms and related strategies of acyl-homoserine lactones (AHL) lactonase, which is an important but largely unexplored enzyme. We also detail the status and catalytic mechanism of the main types of polysaccharide-degrading enzymes that broadly exist among marine microorganisms but have been poorly explored. In order to facilitate understanding, the regulatory and synthetic biology strategies of terrestrial microorganisms are also mentioned in comparison. We anticipate that this review will provide an outline of multiple strategies for promising marine microbial enzymes and open new avenues for the exploration, engineering and application of various enzymes.

Review
Microorganisms are exceptional at producing several volatile substances called microbial volatile organic compounds (mVOCs). The mVOCs allow the microorganism to communicate with other organisms via both inter and intracellular signaling pathways. Recent investigation has revealed that mVOCs are chemically very diverse and play vital roles in plant interactions and microbial communication. The mVOCs can also modify the plant's physiological and hormonal pathways to augment plant growth and production. Moreover, mVOCs have been affirmed for effective alleviation of stresses, and also act as an elicitor of plant immunity. Thus, mVOCs act as an effective alternative to various chemical fertilizers and pesticides. The present review summarizes the recent findings about mVOCs and their roles in inter and intra-kingdoms interactions. Prospects for improving soil fertility, food safety, and security are affirmed for mVOCs application for sustainable agriculture.

BACKGROUND
Inevitably, the floors of mosques are contaminated with microorganisms, and the risk of pathogen transmission is probably high between the many visitors, but the issue has been infrequently studied.
OBJECTIVES
Investigate microorganism variety and risk of contamination on commonly used carpets and rosaries (prayer beads).
DESIGN
Cross-sectional.
SETTINGS
Mosques.
METHODS
This study was carried out in three different cities of Turkey in 2023, focusing on mosques located around hospitals. Forty mosques were included in the study and from each mosque 10 samples were collected from various parts of carpets and rosaries. The number of positive culture isolates were identified.
MAIN OUTCOME MEASURES
Diversity and distribution of microorganisms isolated from mosque carpets and rosaries; methicillin-resistance rates in .
SAMPLE SIZE
400 samples.
RESULTS
Growth was observed in 368 (92%) of 400 samples examined. The microorganisms isolated in the highest number were methicillin-susceptible coagulase negative (MSCoNS) (59.8%), (41%) and diphtheroids (31.3%). The rates of total growth (=.001), including diphtheroids (=.018), methicillin-resistant coagulase negative (P=.001), (=.036) and (=.002) rates were significantly higher in the rosary samples than carpet samples. At mosques in Tokat, a province center, 4 samples were positive for , two samples were positive for and one sample for methicillin-resistant (MRSA), and these were isolated from rosaries. 0.3% of isolates were MRSA.
CONCLUSION
As there is a high risk of contamination of carpets and prayer beads on the mosque floor with human flora, the use of appropriate hygiene practices is necessary. We also found some emerging bacteria in addition to the normal human flora.
LIMITATIONS
Our study was conducted in three provinces. Further studies might cover a wider geography.
