Gelatin as a Source of Growth-Promoting Substances for Bacteria.

In the course of studies on the nutritional requirements of some of the more exacting bacteria it wase found that the addition of certain brands of gelatin to a simplified synthetic medium caused growth of a number of bacteria which were unable to develop in the same medium without the gelatin. The use of gelatin in amounts ordinarily employed for culture media produced results which were compa...

Growth Promoting Effect of Hyaluronan Synthesis Promoting Substances on Japanese Eel Leptocephali

Hyaluronans (HAs) are glycosaminoglycans produced in the bodies of Anguilliform and Elopiform leptocephali, and play a role in metabolic energy. In mammals, HA synthesis-promoting substances (HASPS) up-regulate the expression of HA synthase (HAS) and increase the amount of HA in the body. In this study, Japanese eel leptocephali were fed a HASPS containing diet. We analyzed HAS1s and HAS2 expre...

A Critical Study of Some of the Growth-promoting and Growth-inhibiting Substances Present in Brilliant-green Bile Medium.

Improvement of Sorghum Crop through Exogenous Application of Natural Growth-Promoting Substances under a Changing Climate

High temperature during May to July is a major hurdle for production of sorghum as fodder in Pakistan, ultimately resulting in a deficit with respect to the demand of meat and milk for increasing population. A field study was conducted to investigate the impact of exogenous application of natural plant growth-promoting substances on forage yield and quality of sorghum. Seed priming and foliar a...
