    Abstract: This edited volume focuses on the core aspects of sugarcane production-management under stressful environments as well as innovative strategies for augmenting crop growth & productivity through intrinsic and extrinsic manipulations. The various chapters aim at bringing out comprehensive and advance information on different aspects of sugarcane cultivation under stress environments and impact of climate change on the sustainability of sugarcane production. The book encompasses information about crop production management, physiological & nutritional requirements, ratooning, ripening and post-harvest losses management. It also delineates various technologies that support the continued use and improvement of sugarcane as renewable source of food, fiber and bio-energy. The manipulations at cellular and molecular levels, molecular breeding approaches and post-harvest technologies are also included. The area under sugarcane cultivation is gradually increasing because of its diversification potential. The high productivity and biomass of the cane crop also makes it a key source for use as bio-energy crop and a promising raw material for bio-based agro-industries. However, poor crop & biomass productivity due to abiotic stress is the foremost constraint in its future commercial exploitation as sustainable feed-stock for bio-based industries. It is therefore imperative to understand the cellular-molecular modulation responsible to productivity barrier under specific stress situation(s) for better sugarcane quality and quantum under field condition. Some of these innovative approaches are delineated in this book. This book is of interest to progressive sugarcane growers, millers, industrial entrepreneurs, sugarcane scientists, cane development and extension officers, sugar industry managers and valuable source of reference worldwide.

    Notes: An all-solid-state, low-cost device for fluorescent wavelength-ratiometric detection is described. Ultrabright light-emitting diodes were used as light sources. This allowed electronic modulation of the light, simple optical configuration, and miniaturization of the instrument. Narrow-bandpass interference filters were used for wavelength separation. Detection was accomplished by high-sensitivity, large-surface PIN photodiodes. An integrating double-ramp technique with fixed upper and lower thresholds was employed for conversion of the light intensities into time intervals. The duty ratio of the output signal was a function of the fluorescence intensity ratio. Additionally, the concentration of the fluorophore could be measured. The device could be easily designed as a battery-operated version. It could be used for a variety of ratiometric fluorescence measurements. © 1999 American Institute of Physics.

    Notes: We have characterized the output of inexpensive, commercially available single quantum well (SQW) blue and green light emitting diodes (LEDs). The SQW LEDs were amplitude modulated with the output from a frequency generator while biased through a bias tee with 5 mA of current. The blue SQW LED produced 800 μW of light centered at 466 nm, with a −3 dB bandwidth of 58 MHz. The green SQW LED produced 543 μW of light centered at 522 nm, with a −3 dB bandwidth of 26 MHz. Modulated light was available to approximately 100 MHz, allowing the measurement of ns fluorescence lifetimes. The fluorescence lifetime of a standard fluorophore (fluorescein) was measured in the frequency domain using the phase-modulation technique, and gave results similar to those obtained with a 488 nm argon ion laser modulated with a Pockels cell. To demonstrate the usefulness of the SQW LED source, we also performed measurements with the fluorescent pH indicator SNAFL-2. Again, these results compared favorably with those obtained with the laser. When compared to a laser modulated with a Pockels cell, the SQW LEDs were smaller, less expensive, required less power, generated less heat, and required less alignment. The ability to modulate the SQW LEDs at high frequencies, along with the blue or green outputs, allow their use as inexpensive light sources in fluorescence lifetime optical sensors and even fluorometers. © 1996 American Institute of Physics.

    Notes: Summary The metabolic relationship between the solventogenic state in Clostridium acetobutylicum and intracellular NADH levels was investigated using culture fluorescence as a technique for continuous monitoring of in vivo NADH levels. Continuous culture experiments showed that a transition from acidogenic to solventogenic state was accompanied by a decrease in culture fluorescence, which was interpreted as a decrease in NADH level. It appears that NADH/NAD+ turnover rates may be more significant than NADH levels in determining the metabolic state of the cell. This result provides important new information on regulation of the intracellular reduction state in Clostridium acetobutylicum. Culture fluorescence is shown to be a useful technique for non-invasive on-line monitoring of the metabolic state in continuous acetone-butanol fermentations.

    Notes: We investigated the relationship of dissolved oxygen and culture redox potential (CRP) on amino acid production. Corynebacterium glutamicum ATCC 14296 was used for all experiments. The fermentation can be divided into a growth phase and a production phase. Our results indicate that in order to get higher amino acid production, a lower oxygen supply during the exponential phase is favored. A higher oxygen supply rate appears to be necessary during the production phase. Culture redox potential (CRP) was used to monitor the fermentation. CRP readings were observed to drop to a characteristic minimum value as the metabolic state changed from a growth to production phase. This was evidenced by the commencement of amino acid production and a simultaneous uptake of lactate. Upon lactate exhaustion, the CRP increased abruptly. At the same time, maximal amino acid yields were observed. By the use of minimum CRP as an indication of metabolic phase changes, the agitation rate was changed to increase oxygen supply during the production phase. This significantly increased amino acid production. These results show that culture redox potential measurements can be used to monitor and optimize amino acid production by process manipulation.

    Notes: We present an intensity based sensor designed for on-line monitoring of green fluorescent protein, a revolutionary marker of protein expression. The device consisted of a blue light emitting diode as the excitation source. A band pass excitation filter cut off light longer than 490 nm. The light was directed into a bifurcated optical fiber bundle with the common end inserted into a stainless steel housing equipped with a quartz window. The fiber bundle and stainless steel housing are steam sterilizable. The emission radiation was collected through a long wave pass filter to reject the excitation light shorter than 505 nm and was detected by a photomultiplier tube. The signal was amplified and sent to a computer for recording time course data. The sensor was tested in an Escherichia coli fermentation of JM105 transformed with pBAD-GFP. The on-line signal was compared to off-line fluorescence spectrophotometer measurements. The on-line profile closely followed the off-line. Western blot data showed that with a time shift, the sensor was able to both continuously and quantitatively monitor expression of green fluorescent protein on-line in real time. © 1997 John Wiley & Sons, Inc.
