Sensor Technology Automates Agriculture Ascendancy in Individual Use Bioreactors

Bioprocessing dates aback over 100 years, in fact, beer accomplishment is a bioprocess operation and aboriginal bioreactors could be as simple as oak casks. The added contempo history of bioreactors is bedeviled by either bottle reactor vessels, which are about acclimated in action development and sized at 2 to 25 liters, or stainless steel, which are acclimated in pilot plants and manufacturing. Stainless animate reactors can ambit from a few 100 liters to 10,000 liters or more. Aback in the 1980s, ascendancy of these reactors was mainly via off-line sampling and analog controls. By the 1990s, the argosy were actual abundant the same; about ascendancy had become digitally based. Participants were converting a amount of off-line measurements, pH for example, to in-situ, absolute time measurement. Today, we see an industry area the action and media are abundant added complex, development times are extending and the amount of biologic analysis is increasing. At the aforementioned time stainless animate accessories crave top basic investment, cogent body and allotment times and are adamant to changes to achievement demand. They do accept the advantage of re-usability but, in abounding cases, this is added than account by the amount of cleaning, sterilization and maintenance. In an accomplishment to abatement the amount abject and access adaptability a archetype about-face is underway employing single-use, disposable technologies, which crave decidedly beneath up-front investment, are awful modular and are faster to implement. The 'new' bioreactor is a sterilized, disposable, artificial bag. Individual use reactors are currently sized up to 2,000 liters and crave no on-going maintenance.

Forecasted beforehand in individual use for accomplishment is accepted to be 55% per annum over the next three years in a bazaar admired at $2.8B by 2016. The archetype about-face from re-useable stainless and bottle to single-use is a cogent acknowledgment to the industry challenges. As the industry moves to disposable reactors for accomplishment it is aswell gluttonous to abate its action development costs and timescales. This is arch to the acceptance of awful alongside mini-reactors, which can be beneath than 250 ml and attending agnate to Tic-Tac boxes. These systems acquiesce action development engineers to run assorted circumstantial action 'trials' as they seek to optimize their process. These axiological changes in both action development and accomplishment highlight a amount of ascendancy and altitude issues. Firstly, C&M sensors now charge to fit into abundant abate reactor vessels. Secondly, they charge to be at a 'disposable' amount point and, thirdly, they have to be accessible beyond the absolute ambit of reactor vessels. Some of the absolute technologies may accomplish the alteration to this new operating model. Others may be added bound in their use. Finally, as able-bodied as the concrete claim imposed on catalytic gas sensor by this archetype shift, the industry is searching for sensors and systems which action new altitude ambit to accompaniment their absolute techniques and acquiesce users bigger action ascendancy and ultimately college action yields and beneath development times. That is area a micro-optical sensor is proving to be of abundant value. Working with solid accompaniment silicon and cilia optic technology, Stratophase, for example, has developed a micro optical sensor that is absolutely optimized for real-time, in-situ bioprocess ascendancy and ecology beyond the abounding reactor range. A patented accomplishment action produces optical structures that avenue ablaze about a baby silicon chip. By immersing the sensor in the action media the refractive basis of the media is abstinent directly. This absolute time altitude responds to the metabolic rate, any comestible additions and indicates the end point of the process.

Stratophase micro optical sensor able of assuming real-time, in-situ bioprocess ascendancy and ecology beyond the abounding reactor range. Stratophase micro optical sensor able of performing real-time, in-situ bioprocess control and ecology beyond the abounding reactor range. The micro-optical sensor is allotment of the Ranger System, which is composed of two components: the Ranger Manager assemblage accouterment controls and the Ranger Probe, a real-time optical oxygen sensors residing aural the action media. Advice amid the two accessories is via noise-immune cilia optic cable. Manager contains a laser ablaze source, detectors, abstracts abridgement components, advice modules, and user interface components. The arrangement appearance accepted outputs such as OPC and 4 mA to 40 mA to accredit advice to process-control systems. A two-part paradigm, the Ranger Arrangement employs the Ranger Manager for ascendancy functions and the Ranger Probe, a real-time sensor. A two-part paradigm, the Ranger Arrangement employs the Ranger Manager for ascendancy functions and the Ranger Probe, a real-time sensor. The micro-optical sensor and its ascendancy arrangement accredit action development teams to rapidly optimize their reactor agriculture action which is again acclimated in accomplishment absolute of the reactor style. As a baby silicon accessory it meets key ambit of admeasurement and amount and provides a new, top value, altitude constant to the industry. Conclusion The biotechnology industry is implementing cogent changes in the blazon and acceptance of bioreactor vessels. The deployment of individual use arrangement is advancing rapidly. This presents both a claiming and an befalling for new technologies to emerge, which are adapted in all bioreactor anatomy factors. Additionally, accretion complexity, college amount products, and authoritative directives appeal advances be fabricated in action control. Processing accessories is arch the way with smaller, massively alongside reactors and single-use systems. Ascendancy and altitude technologies have to beforehand rapidly to clue these trends and action new capability, which anon accord to the advantage and amount capability of the industry.
