Determination of the Best Conditions to Produce the Enzyme Chitinase by the Fungus Beauveria bassiana
Proceedings 2024, 103(1), 26; https://doi.org/10.3390/proceedings2024103026 - 26 Jun 2024

Chitinases, enzymes produced by diverse organisms like bacteria, fungi, insects, plants, and humans, play a crucial role in degrading the biopolymer chitin. They have wide-ranging applications, including abilities to isolate protoplasts from fungi, control pathogenic fungi, treat chitinous waste, and manage disease transmission viinsects due to their chitin-degrading ability. This study focused on determining optimal conditions for chitinase production using the fungus Beauveria bassiana, acknowledging the enzyme’s significant importance. The strain employed was B. bassiana 487 from Embrapa, registered in the ARSEF database. Three media (Hill, Adams, and Medium 2) were assessed with or without shrimp exoskeletons as an inducer over a 10-day period. Initial fermentation conditions included a pH of 5.5, a temperature of 28 °C, stirring at 120 rpm, and an inoculum size of 107 cells/mL. Production and enzymatic activity were evaluated, monitored for 7 days, with the tenth day dedicated to identifying optimal production conditions. Medium 2 demonstrated superior production when supplemented with the inducer, reaching its peak on the seventh day. Following the medium selection, chitinase enzymatic activity in Medium 2 with the inducer was assessed. Until the eighth day, B. bassiana 487 showed low enzyme production, with an enzymatic activity of 6.08 nmol/mL.min. A significant increase occurred on the ninth day, reaching 348.94 nmol/mL.min. High activity persisted on the tenth and eleventh days, with values of 302.45 and 264.59 nmol/mL.min, respectively. In conclusion, for enhanced chitinase production by B. bassiana 487, we recommend using Medium 2 over a 10-day fermentation period under suitable conditions.

We demonstrate the systematic optimization of SnO2-based thin-film chemical sensors by using mono-, bi- and tri metallic nanoparticles (NPs) composed of Ag, Pd, and Ru, which are deposited via magnetron sputtering inert gas condensation. The ultrathin SnO2 films are integrated on CMOS-based micro-hotplate devices, where each chip contains 16 sensor devices in total. We found that the response of the sensor device can be significantly tuned to specific target gases, such as CO and VOCs, by using various types of NPs.

Guiding mechanisms are among the most elementary components of in-plane micro-electro-mechanical systems (MEMS). Usually, a spring is desired that is compliant in only one direction and stiff in other directions. We introduce triangular springs with a preset tilting angle. The tilting angle lowers the force reaction in the displacement direction and implements a constant-force reaction whereby the maximum selectivity of the tilted triangular spring is shifted to larger displacements. Thus, the tilted triangular springs can increase the lateral stability of comb-drive actuators. We show tilted triangular springs exhibiting constant forces in a deflection range of about 75 µm to 175 µm.

The development of novel sensing materials and analytical systems remains challenging nowadays. Among various transduction principles employed in chemical sensors, the optical transduction is often preferred, due to the fast response time, simplicity of preparation, and easy signal acquisition of optodes. In this contribution, the main aspects of novel optical sensor development and their application in both single and array configurations for liquid sample analysis will be discussed. The applications of fluorimetric and colorimetric all-solid-state optical sensors and sensory arrays recently developed or under investigation for ecological monitoring, quality assessment, and medical and health care will be illustrated.

Lung cancer remains a formidable global health challenge, necessitating the exploration of innovative diagnostic approaches for early detection. This review paper delves into the burgeoning field of exhaled breath analysis using electronic nose (e-nose) technology for the identification of volatile organic compounds (VOCs) as potential biomarkers for lung cancer diagnosis. An electronic nose inspired by the human olfactory system comprises an array of sensors that can detect and differentiate complex odor profiles. This paper elucidates the principles behind e-nose technology and its application in capturing the unique VOC signatures present in exhaled breath, which serve as indicators of underlying physiological conditions. A significant portion of this review is dedicated to elucidating the methodology and advancements in e-nose-based VOC analysis, providing insights into the potential of this non-invasive approach for disease diagnosis. The exploration extends beyond general applications to specifically spotlight the utilization of e-nose technology in the realm of early lung cancer detection. E-nose-based disease diagnosis, and more specifically, lung cancer detection, is discussed in detail, with an emphasis on the recent studies and advancements. The potential of VOC profiling as a reliable and early diagnostic tool for lung cancer is explored, addressing both the promises and challenges associated with this cutting-edge approach. This comprehensive review amalgamates the current state of knowledge in the field, offering a roadmap for future research opportunities and the realization of e-nose technology’s promise in revolutionizing lung cancer diagnosis.

Insects destroy approximately one third of the world’s annual crop production. Their early detection enables the implementation of appropriate measures to prevent excessive infestation. Insects use species-specific chemical signals known as pheromones to communicate and attract their conspecifics. Interestingly, these pheromones are used to lure insects into traps for pest control purposes. Despite its effectiveness, this method is laborious and time-consuming as it requires frequent observations to identify and count the captures. As an alternative, the detection of pheromones is a promising solution for insect surveillance. In this context, we are developing biosensors based on pheromone receptors (PRs) immobilized on diamond-based capacitive micromachined ultrasonic transducers (CMUT) with the aim of achieving highly selective detection of pest insect pheromones.

A novel methodology for the sizing of magnetic nanoparticles (MNPs) based on diffusion is described herein. The sensing core is an electrical coil wrapped around a capillary filled by an MNP solution. We show that it is possible to determine MNPs’ hydrodynamic radius by employing off-the-shelf electronic equipment by measuring the decrease in coil inductance when MNPs diffuse out of the coil by Brownian motion.

The development of 3D porous nanocarbon composites has improved the performance of piezoresistive sensors. However, the functionalization and surface distribution of nanocarbon may limit conductivity and mechanical stability. In this study, a mechanochemical approach was developed to create an elastomeric/CNTs 3D porous nanocomposite. By changing parameters such as CNT length and polymer amount, different composites with improved piezoresistive properties can be produced for wearables or fluidic devices. The material can withstand compressive stress up to 150 Kpa and has a sensitivity of up to 330 Kpa−1 and a limit of detection of 0.2 Pa and 50 nm for pressure and extension, respectively.
