Abstract:
Disclosed is a method for producing bacterial cellulose using a Gluconacetobacter sp. KCG326 strain. Specifically, a method for producing bacterial cellulose disclosed in the present invention can increase production yield of the bacterial cellulose by Gluconacetobacter sp. KCG326 strain using sucrose as a carbon source and yeast extract or soytone as a nitrogen source.
Abstract:
A portable device for non-destructively measuring the sugar content of a mandarin, according to the present invention, comprises: a measuring head unit; a light emitting unit which is arranged on the measuring head unit to emit light onto a target object, a mandarin, for measuring the sugar content; a light-intercepting-and-spectrum head unit which is spaced apart from the light emitting unit at a predetermined distance, so as to receive light from the mandarin; and an elastic pad which is tightly fixed onto the front side of the measuring head unit. An ultra-miniature spectrum head and a light emitting diode integrated module are included, so as to enable miniaturization, weight-lightening, and reduction in power consumption and price.
