Anaerobic bacteria outnumber aerobic bacteria in many sites of the human body. They are commonly found in the mouth, skin, intestines, and colon. While earlier classification was based on colony morphology and biochemical reactions, current classification is based on DNA analysis and fatty acid profiles. Obligate anaerobic bacteria lack metabolic pathways using oxygen and are susceptible to oxygen radicals. They are an important cause of infections and are often found growing with other bacteria. Identification requires use of specialized techniques to cultivate in an oxygen-free environment.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

The numbers of anaerobes have been
estimated to be 10 4-10 5/ml in small
intestine,10 8/ml in saliva and 10 11/g in the
colon

Aerobes and facultative anaerobes have
metabolic systems listed below, whereas
anaerobic bacteria do not
▪ Cytochrome system of metabolism of oxygen.
▪ Superoxide dismutase, which catalyses the following
reaction:
▪ O-2+O-2----H2O2+O2
▪ Catalase, which catalyses the following reaction.
▪ 2H2O2----2H2O+O2 (gas bubbles).

7. Anaerobic bacteria do not have cytochrome
systems for metabolism.
Less fastidious anaerobes have low levels of
superoxide dismutase and may not have
catalase.
Obligate anaerobes usually lack superoxide

lethal effects of oxygen radicals.
Most human infections are caused by
