Application of microbial resources in biorefineries: Current trend and future prospects

The recent growing interest in sustainable and alternative sources of energy and bio-based products has driven the paradigm shift to an integrated model termed "biorefinery." Biorefinery framework implements the concepts of novel eco-technologies and eco-efficient processes for the sustainable production of energy and value-added biomolecules. The utilization of microbial resources for the production of various value-added products has been documented in the literatures. However, the appointment of these microbial resources in integrated resource management requires a better understanding of their status. The main of aim of this review is to provide an overview on the defined positioning and overall contribution of the microbial resources, i.e., algae, fungi and bacteria, for various bioprocesses and generation of multiple products from a single biorefinery. By utilizing waste material as a feedstock, biofuels can be generated by microalgae while sequestering environmental carbon and producing value added compounds as by-products. In parallel, fungal biorefineries are prolific producers of lignocellulose degrading enzymes along with pharmaceutically important novel products. Conversely, bacterial biorefineries emerge as a preferred platform for the transformation of standard cells into proficient bio-factories, developing chassis and turbo cells for enhanced target compound production. This comprehensive review is poised to offer an intricate exploration of the current trends, obstacles, and prospective pathways of microbial biorefineries, for the development of future biorefineries.

The influence of emotional intelligence on team performance through knowledge sharing, team conflict, and the structure mechanism

Purpose

To analyze the influence of emotional intelligence on team performance, knowledge sharing, team conflict, and the structure mechanism, the influence of knowledge sharing, team conflict, the structure mechanism, and emotional intelligence on team performance, and the influence of emotional intelligence on team performance through knowledge sharing, team conflict, and the structure mechanism.

Design/methodology/approach

This research uses the quantitative research method and is included in explanatory research. Data collection was done cross-sectionally. This research was conducted at provincial hospitals in South Sulawesi and in Central Sulawesi.

Findings

Emotional intelligence directly influences knowledge sharing, conflict in teams, the structure mechanism, and team performance. There is a direct influence of knowledge sharing, team conflict, and the structure mechanism on team performance. Then, there is an indirect influence of emotional intelligence on team performance through the mediation of knowledge sharing, team conflict, and the structure mechanism.

Originality/value

The novelty of this research is in its effort to observe the mediation of knowledge sharing, team conflict and the structure mechanism with other variables developed in the research model. No previous studies have found a relationship between emotional intelligence and team performance, knowledge sharing, team conflict, and the structure mechanism, or the influence of knowledge sharing, team conflict, the structure mechanism, and emotional intelligence on team performance.

Mucor nidicola sp. nov., a fungal species isolated from an invasive paper wasp nest

A strain of a novel mucoralean fungus was isolated from a nest of the invasive paper wasp, Polistes dominulus. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and 5.8S rRNA gene sequences, along with physiological tests, revealed that this strain represents a novel species within the genus Mucor. The novel species also includes a representative that had previously been characterized as part of the Mucor hiemalis complex. Unlike the type strain of M. hiemalis, these two strains can grow at 37 °C and sporulate at 35 °C. Here, we present a partial resolution of the M. hiemalis species complex and propose the novel species Mucor nidicola sp. nov. to accommodate the isolate; the type strain of M. nidicola is F53T ( = NRRL 54520T = UAMH 11442T = CBS 130359T).

Green synthesis of gold nanoparticles using palm oil mill effluent (POME): a low-cost and eco-friendly viable approach

The present study reports the synthesis of gold nanoparticles (AuNps) from gold precursor using palm oil mill effluent (POME) without adding external surfactant, capping agent or template. The biosynthesized AuNps were characterized by using UV-vis spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). According to the image analysis performed on a representative TEM micrograph by counting 258 particles, the obtained AuNps are predominantly spherical with an average size of 18.75 ± 5.96 nm. In addition, some triangular and hexagonal nanoparticles were also observed. The influence of various reaction parameters such as reaction pH, concentration of gold precursor and interaction time to the morphology and size of biosynthesized AuNps was investigated. This study shows the feasibility of using agro waste material for the biosynthesis of AuNps which is potentially more scalable and economic due to its lower cost.
