Abrégé

Induction mutagenesis in lactic acid bacteria for D(+) lactic acid production from starch was performed and the stable mutant strain of Lactobacillus plantarum improved by the molecular biological technique can be used in production of high optically pure D(+) lactic acid directly from various kinds of starch as a carbon source. Those starch substrates are included cassava starch, corn starch and rice starch, etc. The fermentation product is high optically pure D(+) lactic acid up to 90.0-99.0% which is able to apply in bioplastic and pharmaceutical industries.

Abrégé

The present disclosure relates to a radio frequency system for mitigating infestation in agricultural crops, as well as a method of an application of the system. The system comprises a treatment apparatus for treating the agricultural crops with radio frequency radiation. The system also comprises an outlet feeder for feeding the agricultural crops into the treatment apparatus. The agricultural crops flow vertically through the treatment apparatus after being fed therein. An advantage of the present disclosure is that the agricultural crops are continuously flowing through the system, such that the agricultural crops are subject to radio frequency radiation from the treatment apparatus as they vertically flow through the treatment apparatus. Another advantage is that there are lesser spaces within the agricultural crops due to the vertical flow, leading to more efficient use of the radio frequency radiation from the treatment apparatus.

Abrégé

The present disclosure relates to a dielectric heating system for controlling rice weevils, mold, and/or moisture levels in agricultural products. The system comprises an adjustable output power unit configured to generate and output an electric field. The adjustable output power unit comprises a high-power amplifier circuit having a set of inputs and a plurality of outputs, each input configured to receive a radio frequency (RF) signal, and each output configured to provide an amplified RF signal. The adjustable output power unit also comprises a high-power combiner having a plurality of inputs electrically coupled to the plurality of outputs of the high-power amplifier circuit, and having an output configured to provide a high-power RF output signal. The adjustable output power unit further comprises an impedance matching circuit electrically coupled to the output of the high-power combiner. The adjustable output power unit yet further comprises an output stage or heating unit electrically coupled to the impedance matching circuit. The output stage or heating unit comprises a structure through which a volume of agricultural products can flow and which exposes the agricultural products to the electric field produced by the adjustable output power unit as the agricultural products flow through the structure.
