Extremophilic fungi have received considerable attention recently as new promising sources of biologically active compounds with potential pharmaceutical applications. This study investigated the secondary metabolites of a marine-derived Penicillium ochrochloron isolated from underwater sea sand collected from the North Sea in St. Peter-Ording, Germany. Standard techniques were used for fungal isolation, taxonomic identification, fermentation, extraction, and isolation of fungal secondary metabolites. Chromatographic separation and spectroscopic analyses of the fungal secondary metabolites yielded eight compounds: talumarin A (1), aspergillumarin A (2), andrastin A (3), clavatol (4), 3-acetylphenol (5), methyl 2,5-dihydro-4-hydroxy-5-oxo-3-phenyl-2-furanpropanoate (6), emodin (7) and 2-chloroemodin (8). After co-cultivation with Bacillus subtilis, the fungus was induced to express (-)-striatisporolide A (9). Compound 1 was evaluated for antibacterial activity against Staphylococcus aureus, Acinetobacter baumannii, Mycobacterium smegmatis, and M. tuberculosis, as well as cytotoxicity against THP-1 cells. The compound, however, was not cytotoxic to THP-1 cells and had no antibacterial activity against the microorganisms tested. The compounds isolated from P. ochrochloron in this study are well-known compounds with a wide range of beneficial biological properties that can be explored for pharmaceutical, agricultural, or industrial applications. This study highlights the bioprospecting potential of marine fungi and confirms co-cultivation as a useful strategy for the discovery of new natural products.

In this study, phylogenetic analysis of Turkish Conringia (Brassicaceae) species was conducted based on nuclear ribosomal DNA (nrITS) and chloroplast DNA (trnL-F) sequences. In addition, the relationships between the sequences of some Brassicaceae family species retrieved from NCBI, and Conringia species were documented. All of the plant specimens were collected at their flowering and vegetation periods from different regions of Turkey, and brought to the laboratory. Total genomic DNA was extracted using the GeneMark kit. In PCR analyses, ITS4 and ITS5A primers were used for the amplification of the nrITS region, while the trnLe and trnLf primers were used for the cpDNA trnL-F region. The DNA sequences obtained were then edited using BioEdit and FinchTV, and analyzed using MEGA 6.0 software. Neighbor joining (NJ) and bootstrap trees were constructed in order to identify the relationships among Conringia taxa. The nrITS sequences ranged between 573 and 672 nucleotides, while the trnL-F sequences ranged between 346 and 764 nucleotides. The divergence values of nrITS sequences differed between 0.177 and 0.00 and divergence values of trnL-F sequences differed between 0.902 and 0.00. NJ tree generated using nrITS and trnL-F sequences consisted of two clades. In trees generated with both the nrITS and trnL-F sequences, C. orientalis, C. grandiflora and C. austriaca appeared within the same group. In addition, according to the phylogenetic analysis results obtained with other Brassicaceae species, it is revealed that the Conringia genus is polyphyletic.

The aim of this study is to provide information on the phenology of urban spring season, of some species of ornamental trees and shrubs, in the light of climate changes occurred over the recent decades. Ten species of ornamental shrubs and trees cultivated in two areas of a town located in southwestern Romania were studied. It was found that the spring season phenology of the studied species is dependent on the climatic year, in recording differences between the number of days from November 1 and the beginning of each spring phenophase, both from one species to another and from one climatic year to another, and also from one area to another; the spring phenology starting earlier in the urban area regardless of the species and the climatic year. Higher temperatures, rising from one year to another, are speeding-up the onset and development of spring phenology, regardless of species, and the urban climate through the effect of urban heat island leads to even earlier onset of spring phenophases and shortening of the growing season, so that by phenological differences existing within the species from one climatic year to another and from one climatic zone to another, spring season phenology can be considered an indicator of temperature rise.

Antimicrobial preservatives are widely added to health products to prevent microbial contamination. However, because of the risks attributed to several synthetic agents, manufacturers are searching for new natural agents. Therefore, this work investigated the different physicochemical characteristics of one of those natural ingredients, the essential oil (EO) of Moroccan thyme (Thymus satureioides C.) and its antimicrobial potential against five microbial strains. The physicochemical parameters (density, refractive index, optical rotation, miscibility, acid value, ester value, and flash point) were measured and the chemical composition was determined by GC/MS. The antimicrobial activity was assessed using disc diffusion method and a macrodilution broth method. The EO yield was 1.01% compared to the dry matter. Fifty-two compounds were identified. The major compounds were thymol (28.66%), borneol (21.16%) and α- terpineol (12.33%). The disc diffusion method revealed that all the strains tested showed sensitivity to the EO at concentration of 1636 μg per disc. For the minimum inhibitory concentration (MIC) and the minimum microbicidal concentrations (MMC), similar results were obtained for Staphylococcus aureus and Escherichia coli (640 μg/mL), for Pseudomonas aeruginosa (960 μg/mL) and for Candida albicans (800 μg/mL) baring Aspergillus brasiliensis, which had 480 μg/mL and 640 μg/mL for the MIC and MMC, respectively.

Water, as one of the main sources of life, is an important aspect to public health and safety. Up until now there have been many concerns about water pollution especially in developing countries. Heavy polluted water that is not treated well could cause many concerning diseases that can lead to deaths. Contaminants that are of chemical, physical, and biological origins are commonly found in these water sources. Gram negative bacteria (GNB) have been seen to develop multiple drug and antibiotic resistance, causing more fatal infections. This has become a major concern of public health especially as it makes water treatment more challenging. Our study investigates human coagulation factor II that is responsible for blood clotting as a possible method for water treatment against GNB. By investigating the coagulation protein interaction with several bacterial lipopolysaccharides proteins and calculating the binding affinity of the interaction, the results show factor II has a lower binding affinity compared to previously studied factor VII. This shows possibilities of factor II to hydrolyse several gram-negative bacteria to act as a potential treatment against these GNBs.

Chromosome count is the only direct way to determine the number of chromosomes of a species. This study is often considered trivial that seldom described and discussed in detail. Therefore, it is inevitable that the chromosome count protocol should be revised and revisited before it becomes obliterated. In the present study, we encountered challenges in obtaining a clear micrograph for the chromosome count of active mitotic cells of Neolamarckia cadamba (Roxb.) Bosser (Rubiaceae) root tips. Several obstacles were determined through micrograph observation, such as existing unwanted particles in cells, poor chromosome staining and chromosome clumping. To overcome these, root tip types, staining methodologies, squashing methods were among the factors assessed to obtain clear micrographs. The chromosome counts of N. cadamba under optimized procedure showed 2n = 44 chromosomes. We also apply digital technology in chromosome counts, such as online databases and graphic software that are open source and freely accessible to the public. Only basic laboratory equipment and chemicals were used throughout the study, thus making this study economical and applicable in a basic laboratory. The availability of online digital software and databases provide open-source platforms that will ease the efforts in chromosome count.
