Calorific contents of microorganisms

Calorific values and ash contents of different organs of Masson pine (Pinus massoniana) in southern China

Calorific values of plants are important indices for evaluating and reflecting material cycle and energy conversion in forest ecosystems. Based on the data of Masson Pine (Pinus massoniana) in southern China, the calorific values (CVs) and ash contents (ACs) of different plant organs were analyzed systematically using hypothesis test and regression analysis in this paper. The results show: (i) ...

Health Safety of Soft Drinks: Contents, Containers, and Microorganisms

Soft drinks consumption is still a controversial issue for public health and public policy. Over the years, numerous studies have been conducted into the possible links between soft drink intake and medical problems, the results of which, however, remain highly contested. Nevertheless, as a result, increasing emphasis is being placed on the health properties of soft drinks, by both the industry...

Calorific content of certain bacteria and fungi.

Calorific contents of dried cells of several representative species of bacteria (gram-negative rods and gram-positive rods and cocci), two species of yeasts, and a filamentous fungus were determined by bomb calorimetry. The grand mean was 5,383 cal per g of ash-free dry weight. This value was then used to determine quantity of energy assimilated (E(a)) during growth. Subsequently, E(a) was empl...

High pressure inactivation of microorganisms inoculated into ovine milk of different fat contents.

High hydrostatic pressure inactivation of Escherichia coli, Pseudomonas fluorescens, Listeria innocua, Staphylococcus aureus, and Lactobacillus helveticus were studied. These microorganisms were inoculated at a concentration between 10(7) and 10(8) cfu/ml in Ringer solution and in ovine milk adjusted to 0, 6, and 50% fat content to evaluate the baroprotective effect of fat content on inactivati...
