The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain.

An encumbrance is an estimate of the salary and benefit expense which will occur for the future. Salary and benefit expense encumbrances are generated semi-monthly. Negative encumbrances (liquidations) reverse the prior semi-monthly period encumbrance by changing (reversing) the sign. Encumbrances are only generated for salaried appointments.
From Wikipedia, the free encyclopedia. In accounting and finance, earnings before interest and taxes (EBIT), is a measure of a firm's profit that includes all expenses except interest and income tax expenses. It is the difference between operating revenues and operating expenses. When a firm does not have non-operating income, then operating income is sometimes used as a synonym for EBIT and operating profit. EBIT = revenue â operating expenses (OPEX) + non-operating income.
