The passage discusses the importance of adhering to simple but essential principles in the harvesting, drying, and storage of oil-seeds to prevent losses due to insect and mold infestation. It highlights that these practices can significantly increase the world production of edible fats without increasing the tonnage of oil-seed crops. The text also touches on the classification of bacteria, emphasizing the need for modern methods and criteria to identify and group bacteria effectively. It critiques older classification systems and advocates for a more stable and scientifically grounded approach, using morphology, metabolic activities, and pathogenicity as key criteria. The authors suggest that the "Bergey's Manual of Determinative Bacteriology" should focus on well-characterized species and use stable criteria for species differentiation to improve its practical value.The passage discusses the importance of adhering to simple but essential principles in the harvesting, drying, and storage of oil-seeds to prevent losses due to insect and mold infestation.
