  1. Bacteria • WindaPurnamasari (11A08001) • ApriliaPangestika (11A08002) • YulisnaHawarya (11A08003) • RizkyanaCindylitaAprisiwi (11A08004) • Anna AtiqaPriyadi (11A08005) • Ana Dian Rahayu (11A08006) • SafikaRahmawati (11A08007)

  2. Bakteri (Yunani, Bakterion= batangkecil) Anthony van Leeuwenhoek Orang yang pertama kali melihatbakteridibawahmikroskop (thn 1684) KinibakteridipelajaridalambidangBakteriologi

  3. UkuranBakteri • Rata-rata: 1-5 µm (diameter) • Bakteriterkecil: (0.12 µm) • Mycoplasmapneumoniae • SDM: 7.5 µm (diameter) 1 µm = 10-6 m (10-3 mm)

  4. Bentuk-BentukBakteri Chlamydia trachomatis Neisseria gonorrhoeae Diplococcuspneumoniae Staphylococcus aureus Streptococcus mutans Pediococcuscerevisiae

  5. Escherichia coli Propionibacterium acnes Diplobacillus Bacillus anthracis Azotobacter

  6. Vibrio cholerae Thiospirillopsisfloridana Treponemapallidum

  11. Kelompokbakteri Gram + dan Gram – dibedakanberdasarkankomponenpenyusundindingselnya

  12. Is this gram stain positive or negative? Identify the bacteria!

  13. Is this gram stain positive or negative? Identify the bacteria.

  14. Contoh Bakteri Gram Positif & Gram Negatif

  15. Bacteria ReproductionAsexual: BinaryFission

  16. Bacteria Reproduction Sexual • Denganpertukaranmaterigenetik (rekombinasigenetik) sehinggamenghasilkanselanakan yang memilikikombinasimaterigenetikdariduaselinduk • Dilakukandengan 3 carayaitu: • Transformasi • Transduksi • Konjugasi

  17. Bacteria ReproductionConjugation

  18. KlasifikasiBakteri Diklasifikasikanberdasarkanciristrukturtubuhmenjadi 2 kelompok: Archaebacteria(Archaio: kuno, Yunani) Kelompokbakteri yang dindingselnyatidakmengandungpeptidoglikan Membranplasmanyamengandung lipid Hiduppadalingkunganekstrimmiripbumipurbakala Eubacteria(Eu: sejati, Yunani) Disebutbakterisejati Memilikiciridanstrukturtubuhsepertibakteri yang kitakenalsehari-hari (telahdibahas)

  19. Types of Archaebacteria Methanogensliving in sewage and stomach of cow Thermoacidophilieslivingin hot springs Extreme halophile living in the Great Salt Lake

  20. Cara Bakteri Memperoleh Nutrisi • BakteriHeterotrof • BakteriSaprofit • bakteri yang memperolahnutrisidarisisa-sisaorganismeatauprodukorganisme lain • BakteriParasit • bakteri yang memperolehnutrisidariinangnya • BakteriAutotrof • Fotoautotrof • Kemoautotrof

  21. Methods of Respiration • Obligate Aerobes – require O2 (tuberculosis bacteria) • Obligate Anaerobes – die if O2 is present (tetanus) • Facultative Anaerobes – don’t need O2, but aren’t killed by it (E. coli)
