Summary: This study investigated the combined effects of bicarbonate and low temperature on alkaliphilic microalgae Dunaliella salina. It found that the addition of a certain bicarbonate under low temperature could effectively enhance biomass production and accumulation of valuable compounds, such as arachidonic acid (AA) and docosahexaenoic acid (DHA).

Summary: The concentration of sodium bicarbonate and sodium acetate in different combinations with glucose or acetate affected the lipid and starch content of Dunaliella salina. Higher concentrations of sodium bicarbonate and sodium acetate promoted lipid synthesis, while lower concentrations favored starch synthesis. The lipids obtained from D. salina met the international standards for fuel properties.

Summary: The growth of Dunaliella salina and Phormidium versicolor was inhibited by high salinity, while Cylindrotheca closterium was strongly affected. The photosynthetic and antioxidant enzyme activities varied among the species under different light levels and salinity concentrations. P. versicolor and C. closterium strains could be potential sources of extremolytes under high temperature and high salinity conditions.

Summary: In this study, different microalgae were isolated and evaluated for growth and lipid accumulation. The microalgal strains were selected based on their uptake rate of sodium bicarbonate and growth behavior. The Scenedesmus sp. BHU1 strain showed high efficacy in growth and biomass productivity at a sodium bicarbonate concentration of 12mM. This study demonstrates the potential of sodium bicarbonate supplementation in renewable biofuel feedstock using the Scenedesmus sp. BHU1 strain.

Summary: Avocado is a pollinator-dependent crop that is rich in nutrients and vitamins. Insect pollination plays a crucial role in improving fruit quality and yield, particularly in terms of fruit weight, seed weight, and oil content. Supplementing avocado farms with honey bees can further enhance these fruit parameters, contributing to the profitability and marketability of avocado agriculture.

Summary: Beta-galactosidase is an enzyme with both hydrolytic and transgalactosylation properties, which has multiple advantages in the food and dairy industries. Its catalytic process involves transferring a sugar residue from a glycosyl donor to an acceptor. Depending on the source, beta-galactosidase can result in lactose-free products through hydrolysis or prebiotic oligosaccharides through transgalactosylation. Several sources, including bacteria, yeast, fungi, plants, and animals, can provide beta-galactosidase, each with different properties and prebiotic efficacy. Researchers are actively searching for novel sources with diverse properties to meet the increasing demand for prebiotics. This review discusses the properties, catalytic mechanisms, various sources, and lactose hydrolysis properties of beta-galactosidase.

Summary: There is a high demand for the development of nanomedicine for wound tissue regeneration with silver doped nanoceuticals. However, little research has been done on antioxidants-doped silver nanometals and their interaction during the bio-interface mechanism. This study prepared and analyzed c-phycocyanin primed silver nano hybrids (AgcPCNP) for their properties and their effects on gene expression and cell migration in wound healing scenarios. The results showed that AgcPCNP can accelerate fibroblast cell migration and has potential for wound healing biomedical applications.

Summary: In this study, proteomics analysis revealed that the interaction between rice and Methylobacterium oryzae CBMB20 results in dynamic changes in the proteome, promoting rice growth and development. Compared to non-inoculated rice, CBMB20-inoculated rice showed different proteomic compositions and diversification in gene ontology functions.

Summary: The phenomenon of heat stress leading to ferroptosis-like cell death has recently been observed in bacteria as well as plant cells. However, the evidence of ferroptosis in microalgae remains unknown. This study investigated the induction of reactive oxygen species (ROS) and iron-dependent ferroptotic cell death in Chlamydomonas reinhardtii, comparing it with RSL3-induced ferroptosis. The results showed that both heat shock and RSL3 treatment triggered ferroptotic cell death with several characteristic biomarkers, indicating that ferroptotic cell death affects iron homeostasis and lipid peroxidation metabolism in Chlamydomonas.

Summary: The aim of this study was to analyze the glucosinolate content in Choy sum germplasm conserved at the RDA-Genebank. The study found that aliphatic glucosinolates were the most common and aromatic glucosinolates were the least common among the analyzed germplasms. Glucobrassicanapin and progoitrin were identified as highly represented glucosinolates in one of the accessions, which have therapeutic applications.

Summary: A novel actinobacterium strain CFWR-12T was isolated from the larval gut of Protaetia brevitarsis seulensis in Korea and was identified as a new species of the genus Agromyces based on its physiological and genetic characteristics. The strain showed high sequence similarity to Agromyces intestinalis and Agromyces protaetiae, but had distinct differences in average nucleotide identity and digital DNA-DNA hybridization. The findings suggest the presence of a new species, named Agromyces larvae.

Summary: Over the past decade, there has been a noticeable decline in plant biodiversity due to climate change, ecosystem destruction for farmland, and selective breeding for limited traits. This loss of biodiversity presents a major challenge for plant biologists worldwide working on sustainable agricultural solutions. Plant genetic resources centers or genebanks that preserve plant germplasm can play a significant role in addressing this issue.

Summary: The National Agrobiodiversity Center in Jeonju, Republic of Korea is the leading genebank in the country. It has been committed to enriching its collection with foreign genetic resources and has become a world-class plant genetic resources-holding genebank. Steps are being taken to improve accessibility, data availability, and passport information for the collection, as well as to respond to the Nagoya Protocol by supplementing passport data for resources lacking origin information. High-throughput phenotyping techniques using digital methods are being initiated to improve germplasm data and passport information.

Summary: A new series of 8-nitroquinolone-based aromatic heterocyclic acyl hydrazones were synthesized and characterized. They were examined for compatibility as anti-proliferative drugs through molecular docking with proteins related to apoptosis in non-small cell lung cancer. The compounds showed good drug-likeness and low toxicity. Selected compounds exhibited significant cytotoxicity towards A549 cells and showed no toxicity on normal human embryonic kidney cells. The best compounds were further tested for apoptosis detection and investigated for reduced DNA synthesis during the cell cycle.

Summary: This study evaluated the morphological and biochemical traits of 355 leaf mustard accessions. Significant variations were observed in terms of most traits. Sinigrin was found to be the most abundant glucosinolate, while glucobrassicanapin and glucoiberin were the least abundant. Leaf length and width of the petiole were correlated with certain glucosinolates. Accessions with specific traits showed potential for developing new varieties.
