Phototrophs (光能生物)
Photoautotrophs (光自營)
use CO2 as carbon sources
cyanobacteria
green & purple sulfur bacteria
Photoheterotrophs (光異營)
use organic compounds as carbon sources
green & purple nonsulfur bacteria
Use light energy
Oxygenic
cyanobacteria
algae
plants
Chemotrophs (化學能生物)
Use energy from chemicals
Chemoheterotroph (化學異營)
use organic
Saprophytes (腐生) vs Parasites (寄生)
Chemoautotroph (化學自營)
use inorganic
Thiobacillus ferrooxidans (氧化鐵桿菌)
NH3, NO2 - , S, H2S, CO
Energy is used in the Calvin-Benson cycle to fix CO2
Fermentation(發酵) 10941010A 10941061A
Any spoilage (腐敗) of food by microorganisms(10941010a0)
Any process that produces alcoholic beverages(含酒精的饮料) or acidic dairy products(酸性乳制品)10941010a
Any large-scale(大规模) microbial process occurring with or without air(10941010a)
Scientific definition(科学定義)
Releases energy from oxidation of organic molecules(有幾分子)
Does not require oxygen(不需要氧氣)
Does not use the Krebs cycle or ETC( 不使用克雷布斯週期或ETC)
Uses an organic molecule as the final electron acceptor(使用有機分子作為最終電子受體)
種類
Alcohol fermentation
produces ethanol + CO2
Bacteria or yeast
Lactic acid fermentation
produces lactic acid
Streptococcus
Lactobacillus
Homolactic fermentation
produces lactic acid only
Heterolactic fermentation
produces lactic acid and
other compounds
Industrial Uses for Different Types
Catabolism of various organic food molecules
Carbohydrate Catabolism 10941005A 10941030A
The breakdown of carbohydrates to release energy
Krebs cycle
Electron transport chain
Glycolysis
The oxidation of glucose to pyruvic acid produces ATP and NADH
A Summary of Respiration(呼吸總結)
Aerobic respiration(有氧呼吸)
the final electron acceptor in the electron transport chain is molecular
oxygen (O2)
Anaerobic respiration(無氧呼吸)
the final electron acceptor in the electron transport chain is
NOT O2
Yields less energy than aerobic respiration because only part of the Krebs cycle operates
Electron Acceptor (電子受體)
SO4 – Desulfovibrio
CO3 2 –
NO3 – Pseudomonas & bacillus
Products
H2S + H2O
CH4 + H2O
NO2 –, N2 + H2O
