![]() toruloides cultivated on several different carbon sources was used to identify constitutive promoters driving high and medium expression levels of native genes (predicted expression levels are classified as described in “ Methods” section). Of the set of promoters tested, several appear to be good candidates for driving heterologous expression in this host, thus expanding the toolset available for genome editing.Ĭonstruction and characterization of promoter library toruloides promoters by monitoring expression of two fluorescent reporters in four different media over a cultivation period of 7 days. The aim of this study was to characterize native R. Several of these promoters were predicted to be bidirectional. toruloides that are likely to result in high- and medium-level constitutive expression. RNA sequencing analysis was performed to select promoters from R. For this work, a high-efficiency chemical transformation method was adopted from a protocol developed for Saccharomyces cerevisiae to streamline the engineering workflow for R. toruloides is Agrobacterium tumefaciens-mediated transformation (ATMT), a useful strategy for genomic integration of heterologous genes but is a laborious and time-consuming process. The most common method used for transformation of R. In this context, functional bidirectional promoters would be a valuable addition to the toolset, since they can be convenient for optimization of multi-gene pathways. Solid v dotted line in map snapgene viewer full#While promoters that are responsive to certain metabolites are valuable tools, a toolset of well characterized constitutive promoters remains necessary to explore the full potential of strain engineering. toruloides, the majority of them being metabolite-responsive promoters rather than constitutive. A small selection of promoters has already been characterized to modulate expression of heterologous genes in R. A growing branch of synthetic biology involves the pursuit and improvement of standard parts that are reliable, orthogonal and robust for non-conventional hosts. A major need on the tools front is for efficient and stable promoters to express genes of interest and selection markers. To improve prospects for more advanced metabolic engineering in this fungal host, the development of robust genetic tools and resources is an immediate priority. However, the high lipid content indicates a suitability for applications to any acetyl-CoA-derived product, from fatty alcohols, terpenes and methyl ketones to TCA-cycle derived products, with many applications such as fuels, chemicals, and pharmaceuticals. toruloides has focused on lipid accumulation. So far, much of the work on metabolic engineering or bioproduct formation in R. The oleaginous, carotenogenic yeast Rhodosporidium toruloides (also known as Rhodotorula toruloides) is a promising host for sustainable bioproduction due to its innate capacity to efficiently utilize both hexoses and pentoses present in lignocellulosic biomass, as well as its capacity to grow on lignin derived intermediates and aromatics, such as p-coumaric acid and ferulic acid. With the aim of replacing many petrochemical-derived fuels and chemicals with renewable alternatives, the field of metabolic engineering is moving towards the development of microbial hosts that use lignocellulosic biomass as feedstocks for bioproduction. This set of characterized promoters significantly expands the range of engineering tools available for this yeast and can be applied in future metabolic engineering studies. We also identified promoters that may be useful for specific applications such as late-stage expression (e.g., P3, voltage-dependent anion channel protein 2, VDAC2). toruloides is presented here, ranging from a promoter previously used for this purpose (P7, glyceraldehyde 3-phosphate dehydrogenase, GAPDH) to stronger monodirectional (e.g., P15, mitochondrial adenine nucleotide translocator, ANT) and bidirectional (e.g., P9 and P9R, histones H3 and H4, respectively) promoters. ConclusionsĪ set of robust and constitutive promoters to facilitate genetic engineering of R. A total of 20 constitutive promoters (12 monodirectional and 8 bidirectional) were found, and are expected to be of potential value for genetic engineering of R. Promoter expression strength was determined by measurement of EGFP and mRuby2 reporters by flow cytometry. The promoter sequences were selected using transcriptional analysis and several of them were found to drive expression bidirectionally. toruloides promoters, characterized over time in four different media commonly used for cultivation of this yeast. However, there is a lack of characterized promoters to drive expression of heterologous genes for strain engineering in R. A key prerequisite for efficient pathway engineering is the availability of robust genetic tools and resources. Rhodosporidium toruloides is a promising host for the production of bioproducts from lignocellulosic biomass. ![]()

![]() ![]() The latest version of SystemRescue now runs the 5.4.71 LTS (long-term support) Linux kernel, It also includes the dislocker utility to allow users to access data on media encrypted with BitLocker. This has been done away with in the newer release. Earlier versions of the distro featured an elaborate boot menu that spanned across several virtual consoles. The distro is now based on Arch Linux and uses an Xfce desktop. SystemRescue has gone through major changes in the last few releases. One of the oldest distros that’s designed to equip system admins with a variety of tools and utilities to help repair and rescue data from Linux or Windows. Rescatux hosts lots of guides and instructional videos on its websites, and there’s also some documentation to help inexperienced users get started with the distro. After you’ve scrolled through the illustrated documentation and know what to expect, you click the button labelled ‘Run!’ to launch the utility.Īdvanced users can bypass Rescapp and fire up a terminal and access the rescue tool directly. When you click a button, it brings up the relevant documentation which explains in detail what steps Rescatux will take and what information it expects from the user. The buttons inside each category have descriptive labels that help identify their function. The application’s interface has improved through the releases, and in its latest version hosts several buttons divided into various categories, such as Boot, Grub, Filesystem and Password. Upon booting, the distro takes you to the minimal LXDE-powered graphical desktop and automatically fires up its custom helper application called Rescapp. ![]() Unlike many of the other distros in this list, Rescatux can boot on both 64-bit and older 32-bit computers. INSTALL DDRESCUE GUI IN KALI WINDOWSThe distro also ships with tools to rescue data and restore files and can wipe both Windows and Linux installs. ![]() You can very easily use Rescatux for common repair tasks such as restoring bootloaders, repairing filesystems, fixing partition tables and resetting passwords on both Linux and Windows installs. Rescatux ships with a minimal graphical desktop and bundles all the important and useful tools to fix several issues with non-booting Linux and Windows installations. INSTALL DDRESCUE GUI IN KALI UPDATENew users shouldn’t expect much help from the project’s website as well as the documentation there is pretty old, though the developer has promised to update it as well. However, its usability is limited thanks to it being a command-line only distro. This makes it suitable even on machines that can’t boot from USB sticks.įinnix’s tool list is comprehensive, and virtually unrivalled. To that end the layout of the distro is optimized for CD-ROMs, which doesn’t impede when it’s used from a USB, but will result in faster boots from CDs. One of the goals of the distro is to keep the size of the final release small enough to fit inside a CD. There are several other noteworthy features as well including the use of zram swap compression, and improved remote SSH access. For instance, it now uses GRUB as default bootloader for both BIOS and UEFI systems. The distro has had a complete overhaul and now has a new build system based around Debian Testing.įinnix is also a native 64-bit distro now and features several enhancements that make it more usable on modern machines. In fact, the project recently celebrated its 20 year anniversary with a new release. The Finnix distro has been around since the early 2000s and though the project had been languishing for quite a few years, it’s developer has now actively started working on it with regular releases. Here then are the best Linux repair and rescue distros we think are currently available. We looked at how swiftly the distro’s booting, whether there’s a graphical user interface (GUI) or command-line interface (CLI), and how comprehensive the tools are, among other aspects. Some of the basic factors we looked at are space for installation, compatibility with 32 and 64-bit architecture, and the existing documentation. We’ve evaluated these repair and rescue distros in numerous aspects. They not only collate a vast number of healing tools, but they’ll also go the extra mile and help you find the right tool for the job. This is where these specialized rescue distros come into the picture. However, like with most things open source (opens in new tab), it is the sheer number of choices that often confuse the average desktop user who might end up choosing the wrong tool for the job. Of course, there’s no shortage of tools and utilities that’ll help users with their broken Linux (opens in new tab) installs. ![]() ![]() This is typically done through a USB connection. Operating System Compatibilityįor many people, it is important that their voice recorder be able to transfer recordings from the device to a computer. If you demand more out of your voice recorder, more expensive model often has more ways to fine-tune your recordings. Some voice recorders have a simple user interface, ideal for those who don’t need a lot of fancy bells and whistles. ![]() InterfaceĪ voice recorder interface can be measured by two different standards: how easy it is to use, and how advanced and comprehensive the controls are. Bear in mind that recordings at higher bitrates take up more data. While this is is also influenced by the quality of your microphone, the higher the bitrate, the better and clearer your recording will sound. The recording quality plays a major role in how clear your recordings are. This is directly influenced by the recording file (mp3, wave) and by the fidelity, or quality, of the recording. The available storage space, or memory capacity, available on your digital recorder determines how long you are able to record before transferring or deleting files. Five of the most important items of consideration are listed below. #OLYMPUS DIGITAL VOICE RECORDER SOFTWARE#These include recording quality, storage capacity, size of the device, versatility of the machine, systems compatibility, voice recognition software and more. There are a number of factors to keep in mind as you weigh the strengths of various devices. Attorneys and lawyers may use voice recording to help them prepare for a case. Doctors and nurses can use digital voice recorders to capture notes about their patients and record information during a procedure, rather than relying on written notes. If you are in the medical or legal industry, you may want to consider using a voice recorder as well. Some students use voice recorders to capture important parts of a lecture or to help them study for a test. Many famous songwriters use voice recorders to capture musical ideas away from the studio, and business professionals use them to record important points in a conference for easy reference down the road. ![]() Or perhaps you’re a journalist and you use a voice recorder to capture ideas for your next article. Maybe you want to use it to capture ideas like the businessman in the story above. There are any number of reasons why you might need a digital voice recorder. You reach into your briefcase, pull out a voice recorder and capture your thoughts before they have a chance to escape. #OLYMPUS DIGITAL VOICE RECORDER HOW TO#You’ve been mulling over how to present your idea for several days.
