Recent advances in the use of Trichoderma-containing multicomponent microbial inoculants for pathogen control and plant growth promotion
AbstractChemical pesticides and fertilizers are used in agricultural production worldwide to prevent damage from plant pathogenic microorganisms, insects, and nematodes, to minimize crop losses and to preserve crop quality. However, the use of chemical pesticides and fertilizers can severely pollute soil, water, and air, posing risks to the environment and human health. Consequently, developing new, alternative, environment-friendly microbial soil treatment interventions for plant protection and crop yield increase has become indispensable. Members of the filamentous fungal genusTrichoderma (Ascomycota, Sordariomycetes, Hy...

Advances in biotin biosynthesis and biotechnological production in microorganisms
AbstractBiotin, also known as vitamin H or B7, acts as a crucial cofactor in the central metabolism processes of fatty acids, amino acids, and carbohydrates. Biotin has important applications in food additives, biomedicine, and other fields. While the ability to synthesize biotinde novo is confined to microorganisms and plants, humans and animals require substantial daily intake, primarily through dietary sources and intestinal microflora. Currently, chemical synthesis stands as the primary method for commercial biotin production, although microbial biotin production offers an environmentally sustainable alternative with p...

Strategies for the efficient biosynthesis of β-carotene through microbial fermentation
Abstractβ-Carotene is an orange fat-soluble compound, which has been widely used in fields such as food, medicine and cosmetics owing to its anticancer, antioxidant and cardiovascular disease prevention properties. Currently, natural β-carotene is mainly extracted from plants and algae, which cannot meet the growing market demand, while chemical synthesis of β-carotene cannot satisfy the pursuit for natural products of consumers. The β-carotene production through microbial fermentation has become a promising alternative owing to its high efficiency and environmental friendliness. With the rapid de velopment of syntheti...

Synthesis of bio-stabilized silver nanoparticles using Roccella montagnei, their anticandidal capacities & amp; potential to inhibit the virulence factors in fluconazole-resistant Candida albicans
AbstractCandida species is the causative agent in approximately 80% of invasive mycoses and drug-resistantCandida albicans is among the four strains of ‘critical priority group’ framed by WHO. Lichens are endowed with some rare phytochemicals and a plethora of therapeutics viz. antifungal capacities ofRoccella montagnei. Biosynthesis of silver nanoparticles (AgNPs) using lichen could offer an eco-friendly, and cost-effective alternative against emerging ‘microbial resistance.’ Therefore, the objective was to biosynthesize silver nanoparticles (Rm-AgNPs) using a Hydro-alcoholic (1:1) extract ofR. montagnei to develo...

Analysis of the bacterial diversity in Moroccan Jben cheese using TTGE, DGGE, and 16S rRNA sequencing
AbstractThis research investigated the physicochemical, microbiological, and bacterial diversity of Jben cheese, a popular artisanal variety in Morocco. The bacterial diversity was explored using culture-independent methods, including temporal temperature gel electrophoresis (TTGE), denaturing gradient gel electrophoresis (DGGE), and high-throughput sequencing (HTS). Significant intra-sample differences were observed for most physicochemical parameters within each milk type, while inter-sample differences occurred between cow and goat cheeses for dry matter and ash. Jben cheese exhibited distinct characteristics, with low ...

Transcriptional regulators of secondary metabolite biosynthesis in Streptomyces
AbstractIn the post-genome era, great progress has been made in metabolic engineering using recombinant DNA technology to enhance the production of high-value products byStreptomyces. With the development of microbial genome sequencing techniques and bioinformatic tools, a growing number of secondary metabolite (SM) biosynthetic gene clusters inStreptomyces and their biosynthetic logics have been uncovered and elucidated. In order to increase our knowledge about transcriptional regulators in SM ofStreptomyces, this review firstly makes a comprehensive summary of the characterized factors involved in enhancing SM production...

Kinetic modeling and optimization of ethanol fermentation by the marine yeast Wickerhamomyces subpelliculosus ZE75
AbstractThe study aims to enhance ethanol production byWickerhamomyces subpelliculosus ZE75 isolated from marine sediment. In addition, analyzing the kinetic parameters of ethanol production and optimization of the fermentation conditions was performed. The marine yeast isolate ZE75 was selected as the front runner ethanol-producer, with an ethanol yield of 89.77  gL−1. ZE75 was identified relying on the phenotypic and genotypic characteristics ofW. subpelliculosus.

Metabolic engineering Corynebacterium glutamicum for D-chiro-inositol production
AbstractD-chiro-inositol (DCI) is a potential drug for the treatment of type II diabetes and polycystic ovary syndrome. In order to effectively synthesize DCI inCorynebacterium glutamicum, the genes related to inositol catabolism in clustersiol1 andiol2 were knocked out inC. glutamicum SN01 to generate the chassis strain DCI-1. DCI-1 did not grow in and catabolizemyo-inositol (MI). Subsequently, different exogenous and endogenous inosose isomerases were expressed in DCI-1 and their conversion ability of DCI from MI were compared. After fermentation, the strain DCI-7 co-expressing inosose isomerase IolI2 and inositol dehydr...

Navigating the signaling landscape of Ralstonia solanacearum: a study of bacterial two-component systems
AbstractRalstonia solanacearum, the bacterium that causes bacterial wilt, is a destructive phytopathogen that can infect over 450 different plant species. Several agriculturally significant crop plants, including eggplant, tomato, pepper, potato, and ginger, are highly susceptible to this plant disease, which has a global impact on crop quality and yield. There is currently no known preventive method that works well for bacterial wilt. Bacteria use two-component systems (TCSs) to sense their environment constantly and react appropriately. This is achieved by an extracellular sensor kinase (SK) capable of sensing a suitable...

Saponaria officinalis saponins as a factor increasing permeability of Candida yeasts ’ biomembrane
AbstractSaponins are a large group of compounds, produced mostly by plants as a side product of their metabolic activity. These compounds have attracted much attention over the years mostly because of their surface activity and antibacterial, anti-inflammatory and antifungal properties. On the other hand, most of the hitherto research has concerned the action of saponins against microbial cells as a whole. Therefore, knowing the possible interaction of saponins with biomembrane, we decided to check in-vitro the influence of saponin-rich extract ofSaponaria officinalis on spheroplasts of twoCandida sp.
