Introduction
In my September 2023 post, I provided an overview of bacteria the biological domain that includes millions of taxa that share both genetic similarities and an absence of visible internal structures. After a three-month hiatus, I’ll now provide a similar overview of…

Introduction

Now that I’ve provided an overview of the characteristics of all life, I’ll describe the most common types of organisms that contaminate industrial process fluid systems – i.e., oilfield injected and produced waters, fuel-associated waters, heat exchange systems, and countless other systems in which fluids are contained of through which they flow. Historically, the two…

June TLT Sounding Board Question 1: “Do you think that biolubricants are more sensitive to microbiological attacks?”

In Talmudic style, my response to that question is another question: is biolubricant susceptibility to microbial attack – i.e., biodeterioration – a matter of conjecture?! Most of the respondents apparently thought so. However, one responded: “Depends on the composition and overall resistance to microbial attack. I…

All Organisms Share Common Characteristics

As I explained in April’s column, all life forms share at least six common properties (variations of this list that include additional properties):

Order
Growth
Homeostasis
Metabolism
Reproduction
Respiration

In April I focused on order and growth. In May I covered homeostasis and metabolism and in July, reproduction. In this month’s article I will focus on respiration.

Respiration
