Progress in the field of strain engineering is being made by identifying the genetic basis of complex phenotypes, engineering new phenotypes, and combining beneficial phenotypes in industrial hosts. Advances in genomics technologies including high-throughput sequencing and DNA microarrays have improved our ability to make genotype-phenotype correlations. Applications include the analyses of traits that have evolved in nature and traits that have been created in the laboratory. Additionally, newer tools such as Whole Genome Shuffling (WGS), Scalar Analysis of Library Enrichments (SCALEs), global transcription machinery engineering (gTME), and gene-disruption methods such as transposon insertion or site-specific homologous recombination are improving the construction of phenotypic libraries and the selection and analysis of cells with desirable traits. This review focuses on some of these current methods.

Research into the role of probiotics-often referred to as "living supplements"-in cancer therapy is still in its early stages, and uncertainties regarding their effectiveness remain. Relevantly, chemopreventive and therapeutic effects of probiotics have been determined. There is also substantial evidence supporting their potential in cancer treatment such as immunotherapy.

The fermentative production of valuable chemicals from lignocellulosic feedstocks has attracted considerable attention. Although Saccharomyces cerevisiae is a promising microbial host, it lacks the ability to efficiently metabolize xylose, a major component of lignocellulosic feedstocks. The xylose oxidative pathway offers advantages such as simplified metabolic regulation and fewer enzymatic steps.

Due to individual differences, accurate identification of tissue elastic parameters is essential for biomechanical modeling in surgical guidance for hepatic venous injections. This paper aims to acquire the absolute Young's modulus of heterogeneous soft tissues during endoscopic surgery with 2D ultrasound images. First, we introduced a force-sensor-less approach that utilizes a pre-calibrated soft patch with a known Young's modulus and its ultrasound images to calculate the external forces exerted by the probe on the tissue.
